I wish.  I live with a native Sprint 1x800 signal that seems to go on forever, even though I'm surrounded by great Extended LTE. I wish I could use both simultaneously.  In fact, this makes some of the areas on the Sprint coverage map a lie. If the area has Extended LTE available, the coverage map will show that. But if native Sprint 1x is also in the area, you will never connect to that Extended LTE. 

Do we live in the same area? I experience this exact situation.

East KY here. Check out the coverage map between Paintsville, Prestonsburg, and Pikeville. 4 lone Sprint towers. Pikeville is 3G, the two around Prestonsburg are Band 25, and Paintsville has a single tri-band tower. But the entire region has extended LTE via Appalachian Wireless with excellent coverage on Band 12.  Paintsville's 1x800 signal has amazing reach and creates a huge area of exclusion for the Extended LTE.  I don't mind as long as I can text and make calls, the frustrating part is when it hangs on when it shouldn't in the fringe areas and I can't make or receive calls.

I'm in rural west michigan where Sprint's coverage gets spotty at times.  Many times I end up with false SCP logs showing TMobile connections.  I have a few areas that I can hopefully latch onto a tmobile signal once roaming is working.

I just attempted a PRL update, but still on 55069

In Cumberland, Maryland I experience this exact issue, however with US Cellular LTE. These areas are only covered with 3 3G only towers in which data and texts are broken, but calls works. I have made a lot of reports with he executive office and it seems now that they removed the 3G coverage completely and only have Extended LTE shown.

If your picking up a Sprint signal it won't let you roam, no device will roam if it can pick up a signal from it's home network, so during a manual network search if Sprint appears, there is no point attempting to connect to T-Mobile as it will refuse and say it is not allowed.

If it is seeing an LTE signal, it will not allow you to roam. However, there are many instances where devices have been on a roaming LTE signal while connected to Sprint 1x (1900 or 800). I have seen this happen on my devices many times. However, it seems to only happen *after* losing the Sprint 1x signal and switching to roaming. Once that happens, the device seems perfectly happy to continue on roaming LTE even when it reacquires a Sprint 1x signal, and doesn't switch away from the roaming signal until it sees a Sprint LTE signal.

That has not been my experience at all.  When roaming on US Cellular, the moment my phone thinks it sees 1X 800 from Sprint, it immediately ditches the US Cellular LTE signal and tries to connect to 1X 800 until it realizes there was nothing there after all.  Very, very annoying.

Hmm... maybe there is something different about the way roaming on NexTech works versus USCC.

My Pixel 2 does this and previously my GS7 did this in rural Nebraska.

 Maybe the difference is between traditional roaming (counts against your roaming limit) and roaming on extended LTE (which does not). I have seen SCP show Sprint 1X and Appalachian LTE simultaneously but when this happens it is very short-lived and I do not actually have data availability. The LTE signal quickly goes away and only the 1X remains.

Of course this raises the question:  Once T-Mobile roaming is activated and only Sprint 1X is available will phones connect to T-Mobile LTE if available? Will T-Mobile roaming be traditional or extended?

Well, in the examples above both NexTech and USCC are extended LTE now. I don't know if it is a regional thing, or a device thing, but I do recall in a small USCC roaming area nearby that I had a USCC LTE signal and Sprint 1x signal for a time as I was re-entering Sprint coverage, it only lasted a couple minutes as I was soon in range of Sprint LTE, but data didn't seem to be disrupted. This is on the LG G6. 

I suspect that, for now at least, you will need to lose all Sprint signal in order to connect to T-Mobile LTE. I would guess that it probably won't let you hold on if you have a Sprint 1x signal. Roaming on T-Mobile sounds to be extended LTE rather than coming out of the 100MB roaming bucket.

According to todays T-Mobile Earnings Call the T-Mobile roaming is LTE Data only and in the example given outside of Sprint coverage your device would use T-Mobile LTE for Data and Verizon for CDMA voice.

That’s exactly what they do with AT&T. I usually roam on Verizon 1X and ATT LTE. I guess I will start seeing T-Mobile LTE instead when it’s active.

According to Sprint's earnings call today, Marcelo said that it would take them 60 to 90 days to implement TMobile Roaming. He said he told John Saw to get it running as soon as possible. Marcelo also said it is significantly cheaper than roaming on Verizon and ATT although he couldn't share numbers.

Sprint doesn't roam on Verizon LTE (data) do they?

What areas of the U.S. has T-Mob LTE where Sprint/USCC/other Extended Networks do not???

1x only on Verizon.

I think mostly the Dakotas, Montana, Wyoming is where T-Mobile may have coverage. Beyond that, it think it's pretty spotty where they have coverage that Sprint or partners do not. I'm not sure if T-Mobile roaming is going to be prioritized over that of USCC or other partners like NexTech or Pioneer.

The South East is a big one. Sprint is pretty pathetic in Alabama to be honest. My phone usually stays on Verizon 1X and ATT LTE when I leave the interstate.

They still do EVDO data roaming too, but the speeds are capped just like they are on At&t LTE and it's not widespread. Before porting out last month, I was able to get data from one Verizon site in rural Texas.

I also noticed that domestic roaming that counts towards your roaming allowance has blocked off video services from places such as YouTube. Videos will not load at all.

It'll be impossible to roam on T-Mobile in most of Wyoming. Outside of Cheyenne, the only LTE band they use is LTE B71.

It takes 60-90 days to activate it on the system.  Keep trying but realistically wait a few months and it should be working.

Going along US-79 between Austin and Longview is a nice test of Sprint's roaming ability. As I type this, I'm on EvDO roaming with VZW; if I had to guess, it's an old Alltel site. Earlier, I was on AT&T LTE (B4 or B17) with VZW or Sprint 1x. The T-Mobile SIM in my tablet is pulling native LTE pretty consistently, bouncing between various bands and CA.

Unfortunately this is the last time I'll be doing this trip for quite awhile, so I won't be able to confirm when roaming goes live on that corridor.

It'll also be interesting to see what happens in the reverse direction. Though realistically the only roaming available in the other direction for me will be on PCS A-F, assuming the network is set up to properly broadcast Band 2 when the frequencies line up. For high end phones that just so happen to have a single variant cross-carrier B26 should be a nice boost in those places where TMobile hasn't built out yet and Sprint has.

EDIT: By the time I finished this message I was split between AT&T LTE and VZW 1x again.

VZW EVDO roaming is available on some sites inside the Texas triangle. Once you get into East Texas (east of I-45), At&t LTE takes over as a roaming partner. Unfortunately, this arrangement has left a lot of holes in roaming. I can confirm that the area west of I-45, south of SH-30, and east of SH-6 has no data roaming whatsoever.

From what I've been able to map, AT&T LTE roaming is available on I-45 starting at the Freeman/Navarro County line and ending at the Walker/Montgomery county line. On I-10, At&t LTE roaming starts somewhere inside Gonzalez county and ends at the Colorado/Austin county line.

      I recently went on an 8 day cruise from NYC to the Caribbean that stopped in Turks and Caicos, Puerto Rico, and the Dominican Republic. My first stop was Grand Turk and there I opted for the free roaming. My S9+ automatically connected to Flow's (Cable & Wireless) LTE network where I received speeds of around 120kbps on average with boosts of up to 150kbps. Something worth noting is that on speed tests, the server prefers to default to Sprint's Miami server as opposed to local servers. Speeds were more than adequate for any amount of web browsing and honestly felt much faster than in reality. It helps that using Chrome will save you data by not loading pictures on certain sites unless you click them.
      In Puerto Rico, I connected to Band 13 on the way into the port in San Juan but once I was in the city, my phone never left Band 41. While the phone was usable, speeds remained significantly lower than what I've come to expect from 3xCA in the mainland U.S. Data speeds peaked at around 25-30Mbos but on average were in the 5-10 Mbps range even on LTE+. Signal remained strong everywhere though. 
      Finally in the Dominican Republic, I entered in Amber Cover which is in Puerto Plata. My phone latched onto a weak Band 2 LTE signal in the port from Altice (called Orange Dominicana in SignalCheck). I had trouble loading pages though. Once off of the ship and out in the open, I had a much stronger signal which allowed me to browse the internet without a hitch. Because it was the last day of my trip, while at the beach I decided to purchase the 24 hour high speed pass for $5. My speeds went from 120kbps to 65Mbps in less than 5 seconds. In some areas speeds were slower, particularly at the port where it struggled to break 2Mbps. Now, back on the boat my phone is flipping between weak Band 4 LTE and overloaded Band 5 HSPA+ from Claro (called Verizon Dominicana in SignalCheck Pro). Here is the difference in speed from before and after purchasing the high speed pass.

      Sprint 4G Rollout Updates
      Friday, April 20, 2012 - 11:31 AM MDT
       
      Is there a "spectrum shortage?" Those two words send shivers down the spines of wireless industry executives. New services demand ever more spectrum, and, the story goes, there simply isn't enough spectrum available. An Internet search engine will easily find hundreds of thousands of links to the term "spectrum shortage." Many claim that it will be the downfall of America.
      The dwindling availability of a finite resource that can't be seen or touched threatens to possibly disrupt the mobile lifestyle that virtually every American has embraced. Dropped cellphone calls, delayed text messages and choppy video streams could become more frequent occurrences because the airwaves on which that data travel are nearing capacity at a time when mobile usage shows no signs of slowing.
      Federal regulators and industry players are searching for ways to fend off the supply-and-demand collision. Dish Network recently acquired a large block of vacant wireless spectrum that pending regulatory approval could be used for mobile broadband services.
       
      Short-Term Plan

      AT&T tried to merge with T-Mobile to solve its own capacity problem. It wanted to get its hands on T-Mobile spectrum. Still, that would have been only a temporary fix at best. Remember all the terrible stories about the quality of AT&T's wireless data network over the last few years? They say they simply don't have enough.
      The reason is that during the last few years, smartphones like the Apple iPhone and the many devices running Android emerged, and wireless data traffic grew like crazy. This problem jumped up and bit AT&T in the rear end. Suddenly, so many people were sucking so much data that the network could not handle it, due to spectrum shortage. Spectrum is like the size of the hose, and a wider hose is needed to carry more data for more customers.
      A couple good things are suddenly happening that may give carriers a little time to solve this increasing problem. Perhaps Verizon starting to sell the iPhone last spring has something to do with it. If so, then now with Sprint selling the iPhone, AT&T will have more breathing room, at least temporarily. That's the good news. However, that reprieve will only last a short while before the exploding smartphone and wireless data growth catches up. Then the other carriers will be faced with the same problem that's confronting AT&T.
      In the first quarter of 2011, the amount of data the average smartphone user consumed each month grew by 89 percent to 435 megabytes from 230 MB during the same quarter in 2010, according to Nielsen research. That's up from about 90 MB in 2009. For reference, the average size of an MP3 music file is about 4 MB.
      "Texting has always been traditionally viewed as a lightweight consumer of bandwidth, but if I start adding videos and pictures to my texts, that also starts consuming more bandwidth," said Tom Cullen, an executive vice president with Dish. But the primary growth driver will be video. Consumers can go through 5 gigabytes a month simply by streaming 10 minutes of standard definition video daily, he said.
       
      Data use is skyrocketing
      Data from the FCC indicate that more Americans are looking at their phones rather than talking on them. In 2009, 67 percent of available spectrum was utilized for voice and 33 percent for Internet data. Those percentages are now at 75 percent for data and 25 percent for voice. With each new iPhone release, data consumption grows. The iPhone 4S eats up twice as much data as the iPhone 4 and three times as much as the iPhone 3G, according to a study by network services firm Arieso. The new iPhone features Siri, a bandwidth-heavy voice recognition feature.
      The FCC estimates the U.S. will face a spectrum deficit of 90 MHz in 2013 and 275 MHz in 2014. To address the crunch, the federal government hopes to unleash 500 MHz of spectrum currently used for other purposes for wireless broadband by 2020. To put that figure in perspective, there is currently 547 MHz of spectrum allocated for mobile services, and AT&T and Verizon each own about 90 MHz.
      The government plans to hold so-called incentive auctions, which will try to lure spectrum owners such as TV broadcasters to sell their licenses. Verizon Wireless has agreed to purchase spectrum from a group of cable-TV companies. Sprint has expressed interest in working with Dish, which acquired the bulk of its 45 MHz of spectrum through two deals for bankrupt satellite technology companies. Dish chairman Charlie Ergen has said that the satellite-TV provider would prefer to partner with an existing wireless carrier on a high speed, 4G network. In response to recent comments by Sprint Chief Financial Officer Joe Euteneuer about the company's interest in working with Dish, Cullen said other wireless carriers are in the same situation. After failing to acquire T-Mobile, analysts expect AT&T to make a play for Dish, a long-rumored merger partner.
      As for T-Mobile, perhaps the most logical buyer is CenturyLink. T-Mobile's German-based parent company has indicated that it might exit the U.S. market. CenturyLink, which acquired Denver-based Qwest last year, is the third-largest landline phone company but does not own a wireless service, unlike the top two, AT&T and Verizon.
      Carriers are trying to offload as much traffic as they can to Wi-Fi networks, which ride on unlicensed spectrum. In some areas, they're installing picocells, which are smaller cell sites that can help boost capacity in dense areas.
      Finally, they're spending billions of dollars on LTE networks that use the airwaves more efficiently. Verizon and AT&T already have 4G LTE networks in place, and Sprint is moving to the technology. Dish says it hopes to enter the mobile broadband market with advanced LTE technology by late 2014 or early 2015. If Dish were to also offer voice service, it would come through VoLTE, which is similar to Voice-over-Internet Protocol (VOIP) phone services. Dish still needs the FCC to drop a condition tied to its spectrum that requires devices to have the ability to communicate with satellites, not just ground-based cell sites. The rule-making process that will likely remove the requirement is underway and could be completed by summer's end.
       
      Is there really a shortage problem?
      The problem, analysts argue, is that the operators that control the greatest amount of unused spectrum may be under-capitalized or unwilling to build out networks to use the spectrum. "We do not believe the U.S. faces a spectrum shortage," Jason Bazinet and Michael Rollins wrote in their Citigroup report. "Too much spectrum is controlled by companies that are not planning on rolling out services or face business and financial challenges. And of the spectrum that is being used, 90 percent of it has been allocated to existing 2G, 3G, and 3.5G wireless services by larger wireless carriers, such as AT&T, Verizon Wireless, Sprint Nextel, and T-Mobile USA.
      In total, U.S. operators have licenses for about 538MHz of wireless spectrum. Only about 192MHz of that spectrum is currently being used. Most of the unused wireless spectrum is owned by companies such as Clearwire, LightSquared, and Dish Network. But so far, LightSquared has been stopped and the other companies have been slow to build networks using their available spectrum.
      "There is definitely a mismatch when it comes to spectrum in the wireless industry," said Paul Gallant, an analyst with MF Global in Washington, D.C. "There are some companies that have spectrum, but they're struggling financially. Or they aren't quite sure what to do with the spectrum. And others that have the money and business model, but need the spectrum." The move to 4G is very important for these operators because it offers them a more efficient way to deliver service. 4G LTE uses the available spectrum roughly 700 percent more efficiently than the 3G wireless technology EV-DO. Carriers will soon be refarming 3G spectrum to 4G LTE in several years.
      A key factor in encouraging efficient use of spectrum has been largely overlooked in carrier boardroom discussions. Wireless providers can add capacity, without obtaining more spectrum, by adding more and more cell sites. Additional cell sites in spectrum constrained areas allow the same spectrum to be used by even more consumers, as well as adding picocells and microcells to denser population areas. So far, the carriers have not expressed too much interest in this method due to additional capital expenditures and overhead. Their strategy is like what Microsoft, Apple and Google have used. It's just cheaper to buy what you need than to invest the time and energy to do the actual work.
      So what can the wireless companies do? To some extent, re-farming their existing networks will help. But so will finding ways to use other spectrum. For example, only T-Mobile lets users make phone calls using Wi-Fi, yet most of the mobile devices available from carriers have this capability; the carriers just don't enable it.
      Allowing Wi-Fi calling could unload millions of voice and data users on to alternative networks and ease the spectrum crunch, at least to some extent. Encouraging VoIP use would also help for two reasons. VoIP doesn't require a lot of bandwidth, and it means that the phone in question uses only the data spectrum, not both voice and data while this is going on.
      These points illustrate that the carriers do have options beyond just buying up spectrum. They can offload more wireless traffic than they do now, build more cell sites into their networks and they can allow the use of other types of communications. While the spectrum crunch isn't going away, that doesn't mean that the process can't be slowed.

      Sprint 4G Rollout Updates
      Tuesday, January 31, 2012 - 7:46 PM MST
       
      Since last fall, there had been talk of a Samsung Galaxy Nexus launching on American carriers other than Big Red. Sprint has finally announced several weeks ago that it is the another vendor slated for release in the U.S. Suffice to say, many of us out there, especially those adverse to heading to Verizon and paying its premium prices, are excited about the impending release.
      The good news is that Google could be working on an updated version of the Galaxy Nexus. It has unofficially been dubbed the Galaxy Nexus Plus. There is much anticipation that it will be released before Sprint turns on LTE this summer. It’s not the first time an OEM has refreshed a device and re-released it to the market place, which works to our advantage. It’s rumored that the new Galaxy Nexus will have either a 1.5 or 1.8 GHz Texas Instrument OMAP4670 dual core processor. This would be a significant upgrade from the 1.2 GHz dual core processor found in the current Verizon version.
      We don’t know anything about official specs, but it’s also rumored to have an 8 MP camera. This is a noteworthy upgrade to the 5 MP shooter on the Verizon model (which has been lauded by many techies). We already know that the Sprint model will come installed with Google Wallet, per previous announcements. Some rumors also point to a beefier battery as well. The phone should have all the other features that’s on the current Galaxy Nexus, so now all we have to do is wait.

      Ericsson RRUS31 B25 + RRUS11 B26
      These are the newest and greatest remote radio units to come from Ericsson. 

      The new Ericsson RRUS31  B25 should be fairly distinctive compared to the earlier RRUS11s and now the RRUS12s being deployed by ATT and Verizon. One of these new RRUS31s can do the job of two earlier RRUS11s thus reducing deployment costs for Sprint and complexity in deploying new sites and making it easier for users to spot as there are now 4 jumpers coming out of one RRUS31 rather than two from each RRUS11 that Ericsson originally deployed. 

      All future deployments will be utilizing the new Ericsson RRUS31s. In addition Ericsson are sending crews to their original deployments and swapping out older RRUS11s for these new RRUS31s due to the aforementioned fact that one RRUS31 can do the job of 2 RRUS11s. Weight savings will be significant at sites where there are 4 or 5 RRUS11 B25s that can be replaced by one or 2 RRUS31s. The Ericsson RRUS31 deployment project is known as the 65 Mhz Project.

      Previously Ericsson utilized additional PCS radios and used RF combiners for high capacity setups where they utilized three or more PCS radios. This new setup will utilize a completey new antenna + radio set just like Samsung and run 4x2 MIMO on the LTE antenna / radio set. 
       

       

       

       
      Ericsson RRUS11 B25 [EOL'd] and B26
      A standard Ericsson Network Vision 1.0 site with 3 RRUS11s where two are dedicated to PCS and one to SMR.  

      This type of setup is no longer deployed or utilized in new sites. Existing sites will be slowly converted to newer RRUS31 B25 via the Sprint 65 mhz project. 


       
      Ericsson NV high capacity site [EOL'd]
      3 or 4 PCS RRUs are present for a total of 4 or 5 RRUS11s per antenna.
