Roaming with 4G


Recommended Posts

I thought this was interesting that I could roam and have a 4G connection?

 

 

Yeah...I had that happen in Ft. Worth at one point. Roam on 1x while on Sprint LTE.

How is that possible i could see that on wimax but on LTE shouldn't he be in a Sprint 3G 1x coverage area

 

My Viper has been known to stay connected to Sprint 3G and roam on 1x. Couldn't access 3G data speeds, but the phone showed it was there.

Sometimes when you start roaming, it can be hard to get your device to go back to native. However, your LTE may start scanning and find something before your 1x does.

You can be roaming on 1x and be on sprint EVDO. This is exactly how the PRL is designed.

Wow, the things I learn are invaluable. I figured it was a fluke.

This happened to me last week. I saw both the "Roaming" and "4G" icons in my status bar at the same time. I thought it must have been some kind of glitch, but there was some compelling evidence to the contrary.

 

For one, the “Phone info” menu stated that I was roaming:

I also happened to be logging in Sensorly while it happened. It was the first time I had ever seen the phone record more 4G points than 2G and 3G points:

You were simultaneously roaming on another carrier's CDMA1X network and connected to Sprint's LTE network. That can happen. But you were not roaming on another carrier's LTE network.

Agreed, This has happened to me in Texas. I went over and checked the band and channel assignment and confirmed that I was on another network for 1x. I remained on Sprint LTE.

Holy crap dude... I just quoted a post you made in the other thread pointing you here! You beat me to it 1 minute before I got the chance to even direct you here! Someone's on their game...

 

Oh yeah, I know that these phone's can't roam on LTE, but I thought it was still strange that I was roaming on 1X while connected to LTE.

Not really strange. It can happen on 3g as well. Sprint designed the PRL to search for Sprint Evdo while connected to roaming 1x.

This happens frequently on the LG Viper, because its 1x reception usually runs 10dBm worse than the EVDO.

I had this happen last week in Chicago. Was inside a building and started roaming, made a call and then went by a window and the phone connected to LTE while roaming on US Cellular. The GS3 displays an R instead of the little triangle when connected to LTE and 1x roaming.

I had this same issue. Roaming when on Sprint EVDO shows a triangle, but roaming when on Sprint LTE shows a superscript R. Weird.

Could the Sprint voice be swamped and force someone into roaming... This thread just got me thinking...

 

I imagine it is very rare that voice is overloaded. But I don't believe Sprint would do this. From a financial point of view, that would cost them more money- roaming on Verizon is not free, and certainly not cheap for Sprint.

Yes, but if Sprint were at capacity... I would expect them to push them to another Sprint tower. I was just wondering if they had the means to technically hand them off to a roaming cell under these conditions. I know it would not be their choice, but if it were that or drop the call.... could they do it?

      Hi guys,
      like the title says, I am travelling to the Netherlands and am curious about people's experience with the international roaming passes. 
      Firstly, are they unlimited data, or are they limited with deprioritization?
      Secondly, what are the speeds like?
      I have asked around but have gotten mixed answers.
      Thanks!

      When Virgin Mobile introduced their Inner Circle plan they added Extended coverage giving them the same coverage as Sprint Postpaid. And a few months ago when Virgin did away with its Inner Circle plan and its iPhone only to the current plan lineup and devices I figured they'd backtrack on the roaming and go back to Sprint only. While they may not have updated their coverage map it would seem they are not allowing roaming as my LG Tribute Dynasty which is compatible with US Cellular roaming is being restricted and blocked post activation. Before hands free activation began I was able to go into the devices network and roaming settings and switch on voice roaming, which worked, it immediately connected to US Cellular, then the hands free activation started which couldn't complete due to no data until I switched on wifi, but after the device rebooted, the voice roaming was turned off and greyed out so it couldn't be switched back on.
      I know this device is capable of roaming, it has band 12 and band 5 for LTE and the CDMA band necessary to roam onto US Cellulars CDMA network, which again it was able to due prior to activation. If Virgin Mobile is going to continue having roaming as an option then it should work otherwise they need to remove it from their coverage map. I've attempted to take the issue up with Virgin but they tell me that they'll help me with any other issue, except roaming. I believe it has something to do with the PRL since it is what determines the devices roaming. I found a old Virgin device from before Inner Circle started, in it was PRL 7080 the same one as it has now, back then Virgin was the home network on Sprint only, no data or voice roaming.
      I don't know where the issue is with this and I'm hoping after filing a complaint with the FCC which has been served that it is either corrected and fixed and roaming starts working, or Virgin removes it from their coverage map if they're not going to allow it. I've asked customer service if the coverage map and the roaming on it applies to current customers or if it was just Inner Circle and they say it does apply to the current plans. If so, and if I have a device that is compatible (LG Tribute Dynasty), why is it being restricted.

      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
      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.

      Sprint 4G Rollout Updates
      Monday, June 25, 2012 - 4:27 PM MDT
       
      As technologies advance, the equipment to use the technology must advance as well. With the upcoming release of 4G LTE in our area (Houston), new equipment will be required to be able to use it. Although Sprint will have numerous data devices to handle the usage by the end of the year, only the Sprint Tri-Band Modem will be available at the rollout of the 4G LTE service.
      Due to the enormous dependence my business has on accessing data in a mobile environment, plus the great increases in data speed available with 4G LTE, this makes getting access to 4G LTE imperative to me. I depended heavily on the Sierra Wireless data devices when I started this business 7 years ago for my source of a reliable method of mobile data transmission. This relationship continued on until the release of the original Hotspot with the 4G service in my area.
      At one point, I was so displeased with past models, that I had sworn I would never buy another Sierra Wireless device as long as I live. This conclusion was reached after having numerous issues with previous hotspot models. There were so many problems that it seemed as if the device was never even tested on the networks it was to be used on. Also Sprint actively blocked reviews of the device, likely to not hinder sales in spite of the problems.
      My need for a new device with both WiMax and LTE capability outweighed my outright dislike of Sierra Wireless products. I proceeded against better judgment, and the Tri-Band modem was ordered even though the possibility of getting a substandard unit once again was always at the forefront of my mind.
       
      On with the show
       

      The official part number of the Tri-Band Modem is 803S. Along with the modem, I also ordered the SSX7077-V desktop cradle. I had to dig through a lot sites to find the information necessary to make this decision for my business. Much to my surprise, even though I was told the cradle was not available yet, I got a Sprint telesales person who was able to use the part number and find they had it in stock.
      Upon arrival I unpacked the unit and cradle...while holding my breath. The device that came out of the box was a pleasant departure from the previous Hotspots I had owned. Above is a picture of the device as it was shipped with all components. There was a small user guide as well but to get the real instructions the user guide must be downloaded from Sprint.
       
      Gone was the one piece blow molded plastic case which allowed no air circulation and caused the prior Hotspots to overheat quickly. Although the display is still too small for my aging eyes (it is actually the same display size as prior units) the change to the case makes it much easier to see in the interior of my van where the device will mostly be used.
      In this picture of the front you can see that there is a new button arrangement as compared to the older Hotspots. Also in the picture is the USB cable for use with the charger or to connect a computer, the AC to USB adapter, the battery and the battery cover. I opened the cradle, which was surprisingly inexpensive, and was delighted to find an additional AC to USB adapter which meant the cradle could be left in place without having to move the adapter around.
      As you look at the modem from the side you can see the antenna ports (the covers are open), the USB connector in the middle and the slot for the memory card. The round hole just right of the left antenna port is the reset button for the unit.

      Here is the same view with the battery and cover installed. Notice that the SD card slot is covered by the
      battery cover.
       

      The opposite side has two switches. The one on the left is a WPS setup button while the one on the right is a slider to mute the unit.
       

       
      The unit sits nicely in the cradle and looks to me to be a solution to help keep the USB port for the charger/interface cable from failing. This has been a major issue with the prior Hotspots. The case of the unit also helps support the USB port to take some of the load off of the circuit board.
      It took quite a bit of digging on the Sierra Wireless site to find out that the antenna ports are for the 4G WiMax band only. The cradle contains 2 5dbi omnidirectional antennas to allow full use of the WiMax network architecture.
       
      Initial testing

      The initial testing of the unit looks promising. The antennas in the cradle for 4G WiMax actually seem to get 3 – 5dBm gain in all conditions tested. The new unit has the ability to search the other bands for signals while staying connected. This allows less downtime between band changes. I notice a lot less disruption when switching bands.
      This unit has better reception on 3G and 4G WiMax than the previous hotspots and even the U600 USB modem I use as well. 4G WiMax is able to connect quickly even at 10% and the cradle has improved stability of WiMax and decreased ping times. For a short time I had access to Sprint 4G LTE as they were testing the towers in my area. The speeds were incredilbly faster. A 10% 4G LTE signal averaged 8.12Mbps download and 1.85Mbps upload. An 80% signal was able to get 35.8Mbps down on my best test and 22.1Mbps up.
      The upload speeds was very unexpected, and much higher than Sprint LTE smartphone devices have reported. This is likely due to much stronger transmit capabilities of the hotspot. I also discovered that when the modem is tethered the cable limits the bandwidth to approximately 20Mbps total speed. It will be interesting to see how it works in the 12 to 14 hour days of hot Houston Weather.
       
      First week in the field
      The Tri Band Modem got pressed into service a little quicker than planned, as my main unit went down with a bad transmission and the U600 USB modem with a Cradlepoint that was in this unit appears to have been damaged by the wrecker’s radio which runs on the edge of the WiMax frequency at 5 watts. The units have been sent in to determine cause of failure and for repairs but I think next time I will make sure all electronics are powered off before getting that close to a transmitter (OUCH!!).
      I am running the same routes in a rental van with the Tri-Band Modem that I normally use the other units on. There is less downtime in the signal gaps I am familiar with and areas where I have had signal problems in both 3G and 4G WiMax are much improved. I have yet to encounter any more 4G LTE signals but am looking forward to the service coming online soon. The unit seems to be running hotter than I would like with a fully charged battery but is actually cooler that the previous Hotspots. The temperature is supposed to soar over the next few days without the cloudiness we have had this past week. So it will be interesting to see if the overheating problems of previous models still occur.
       
      Week 2 – The True test
      The unit is getting worked really hard this week with temperatures outside up near 100 degrees. The GPS is useless with this kind of sun load as the unit will overheat if left in direct sunlight (as the instructions state) in about 20 minutes. The good news is that this is about twice as long as my original Hotspot will last. How anyone can make a unit that requires a clear view of the sky for GPS but can’t handle sunlight is beyond comprehension. A quick check of the Tri-Band’s temperature specs shows that the unit is only rated for 95 degrees. The prior Hotspot was rated well above the century mark but couldn’t even handle 90 degrees for any length of time. The crappiest laptop on the market will handle 105 degrees plus all day long. The true test will be my afternoon calls when the temperatures are high. Battery life has been about 8 to 9 hours which is far better than the prior Hotspots.
      The unit started overheating one afternoon. I can’t say I’m a bit surprised at that, but what is surprising is that it will run steadily as long as the air temp is below 98 degrees. This is a first for Hotspots as they always overheated well before the rated temperature spec. The bad news is the crappy overheat shutdown doesn’t turn off the unit before damage starts to occur, nor does it turn the unit off completely.
      Removing the battery cover seems to help air circulation and overheating some. The button lights are flickering after one overheating but the unit seems to be working fine other than this. It will be interesting to see what happens when it really gets hot here.
      According to the specs 4G LTE takes the least amount of wattage to run so it may not overheat as fast when using 4G LTE. I had the chance to try the modem in the old school 3G EVDO mode as one of my locations is 40 feet underground and that is all that is available at this location. I shut the unit down after 30 minutes as the unit was so hot you could barely handle it even though the temperature underground is around 70 degrees. I would not recommend trying to use this for any length of time if you want the Tri-Band to not overheat!!
       
      My Opinion
      Although Sierra Wireless has made some major improvement in the 3rd generation Hotspot, this is still a unit for the casual user. It is not designed to handle heavy use or outdoor summer temperatures for any length of time. It will be going in my climate controlled cabinet to protect it from the heat next week. I will let you know how it works when the temperature stays below 85 degrees. The improvements in connectivity, reception and stability are worth the investment. As long as you know and adjust your usage for the limitations of the unit.

    • Or, more simply, have a physical SIM that I can just move from one device to another.  Problem [already] solved.  Carrier doesn't have to be involved at any point in the process. I'll be among many (I'm sure) who will be glad to know if you see it.  Here in the DC area, Dish hasn't really done much yet.  I think I've seen some Dish gear around Richmond, but nothing here. - Trip
    • I like VICE.  They actually report on news no one else is willing to report. A lot of the places they go no sane person would want to be there.  They put their life on the line in many cases to get a story. From stories about the avocado wars in Mexico, being in the front lines against ISIS and Ukraine, to being embedded with terrorist organizations.   FAA might have some conspiracy 5G nut on their team or something.  At work ever year we have some one come in and say "hey, can you turn off the WIFI in my room? I don't want its radiation".  It doesn't make sense and their reasoning is always uneducated conspiracy. I can see someone coming into my office and acting crazy over C band disregarding everything else.
    • I think on esims it depends on how they implement it. If you can freely activate them on one phone while having it loaded on many that would be great.   I will let you know when I see Boost Mobile native 5g live here. So far no sign of even the plmn being active which I figure will be my first indicator. I look at changing networks with the TNX Sim and seem to get a full list of all carriers and their alternate plmns.
    • This is a result of the change I mentioned above, sparked by @PedroDaGr8 trying to log AT&T cells with a non-AT&T SIM that was reporting "out of service" but still capturing cell info. For the moment (subject to change as I keep testing and getting feedback), the "Connecting to" prefix will disappear when you connect in a scenario like that. I may adjust it to show a special prefix like "Limited LTE" or "No Data LTE" to make it more clear what is going on, but I also need to make sure that's only appearing at the proper times. When you were seeing just "LTE" in your screenshots, was there anything unusual about your connection? I see the app indicated you couldn't make calls; could you transfer data? Can you send a diagnostic report next time you see that?   I'm seeing this more frequently, unfortunately -- it has something to do with Android's power saving efforts I believe. Was the app in the foreground when it happened? When the screen updates, the notification and home screen widget are also updated -- but as seen with the widget for the past couple of years, Android doesn't always execute the update. I'm constantly trying to find ways around these limitations, since the app is useless if it's displaying stale data.
    • Bleh, hope not.  The eSIM is a huge step backwards to the bad old days and I have no desire to encourage their use. But in any event, maybe I should get Boost service, then, if people are already seeing it.  I can use it for AT&T until Dish native gear goes live in this area.  Have to ponder that a bit. - Trip
