  4. There are areas where I know T-Mobile underperforms in NYC but generally my speeds are more than sufficient and I don't encounter issues with using my phone. The only thing that worries me is that there are some areas where my phone will roam on Sprint's network to make up for T-Mobile's poorer performing network and I'm afraid that T-Mobile may just decommission those Sprint sites without integrating it into their own network, despite the enormous benefit integrating those sites would make.

  5. NYC DoITT and Public Design Commission approved a new design for multi-tenant small cells last month. They look very similar to the previously approved single-tenant design but they're quite a bit taller. Basically the new design means that going forward, a single light pole or utility can have multiple carriers and technologies on it, reducing the number of new poles that needs to be "converted" to densify 4G/5G coverage. It should definitely speed up mmWave deployment once the city starts allowing carriers to build out 5G small cells here.

  7. It's unfortunate that T-Mobile's lax security got them to this point, but it does appear that they've hired some of the best outside consultants to help them get to where they ought to be. Let's hope they mean what they say here. There's another security issue that needs tightening up, too... store employees are often all too willing to make changes to an account without properly checking ID or account PIN information. That should become an immediately fireable offense.

  9. So in my experience, the crazy band hopping and frequent / brief "no data" episodes seem to be a market thing. I spend most of my time in my home area in Fairfield County, CT, but I have an office in Manhattan where I go a few times a month. I don't have a lot of time to use my phone when I'm in my city office, but I have never noticed the two (2) fundamental problems that I experience in CT all the time. For instance, in using the NY Times app, in CT I get "device offline, try again" many times a day, but I have never seen that while using it in NYC. My overall simplistic take on this is that they rush to add 5G all over the country, but that is step 1. Step 2 is to optimize it (logic on band selection, making sure there is appropriate backhaul, etc.). I feel that they prioritize step 2 in the major cities but the suburbs and other areas have to wait until they get to it. Would love to hear more about what is really happening. I miss the good old days of Sprint tri-band LTE working for me like it was supposed to: 2500 while out on the street, changing to 1900 in a building at the perimeter and changing to 800 while deep inside a building in a windowless office or a basement.

  17. There is a common misconception in many companies today that their company is not an Information Technology (IT) company. It does not matter what business you are in, your data and your computer systems are a core part of how your company operates and they are valuable to others who would like to steal that data or prevent your access to your computer systems without paying them money (ransomware) or to use your servers for other processes. If that data and those computer systems are not treated as if they were a target of others by a company's staff, then they will be sloppy with handling the company's data and the security of the computer systems and bad things will occur. Many large companies have an IT security or IT compliance checking department that ensures that all the common security issues are taken care of such as server patching, scheduling penetration testing, verification of user accounts on the computer systems, and verifying that testing systems do not have access to production data. Hopefully T-Mobile's new consulting partners will help them build this capability if they do not already have it in place. It appears that information security is a systemic problem in T-Mobile and I wonder how many additional problems have occurred that have not appeared in public so we do not know about them.

  18. While hiring that company is nice, it should have never gotten to this point in the first place. What is this, like the 3rd time T-Mobile has been hacked. There was no need to keep customer info on their servers like that. Its bad practice as per the NSA general counsel mentioned a while back. While my account wasn't affected, whos to say the next time (and there will be a next time) that it won't be. But as usual, all they get is a slap on the wrists and the customer has to deal with changing passwords, pins, locking credit cards etc.

  23. Adding onto this thread! I went to Roatán, Honduras and CocoCay, Bahamas recently. Here's my experience in both places. Roatán, Hondruas: I bought a 5GB international high speed data pass for $35 from T-Mobile. It lasts 10 days and gives you virtually unrestricted access to partner networks out there. For some background there are 3 networks in Honduras; Tigo, Claro, and Honducel. I did my research and found out that Tigo and Claro are virtually the only two viable carriers in the country. Honducel has a tiny 3G network and controls less than 1% of the market so you'll probably never encounter their network in the country. Upon arrival in Roatán I took my phone off of airplane mode and got a text from T-Mobile welcoming me to Honduras. I also got a text from Claro welcoming me to Honduras which was quite the surprise. Because Roatán is a pretty small island, both Claro and Tigo have signal virtually everywhere with zero coverage dropouts. However it's obvious that Tigo has invested more on the island as they not only have massive macro sites on towers but they have lots of mini-macros/small cells on telephone poles throughout the island to provide infill coverage on mountain roads and in tourist areas. Unfortunately Tigo does not provide T-Mobile customers with access to their LTE network in Roatán, only their HSPA network. Nonetheless it still performed well. Any time I (manually) switched my phone to Tigo's network I had a full signal. Speeds were good everywhere at about 8-10Mbps down and 1 up. On Claro's network, I was seeing average LTE speeds of 7-20 Mbps with peak speeds of 50Mbps. Checking the Service Menu on the iPhone I could see that I was on 20MHz of Band 4 however I'm not sure if it was aggregated with any other bands. Given the speeds I was seeing it definitely seemed like I was only connecting to that single carrier. Claro LTE: CocoCay, Bahamas: The Bahamas has two carriers, BTC which is a state run telecom that is partially owned by Cable & Wireless (the company behind the Flow brand across the Caribbean) and the other carrier is called aliv. Aliv is a relatively new carrier in the has an all LTE network with lower prices than BTC that was created to bring competition to the Bahamian telecom space. I believe that T-Mobile's roaming agreement with BTC predates the arrival of aliv and as a result, T-Mobile doesn't have a roaming deal with them, only with BTC. I couldn't find a coverage map for either carrier on their websites but according to Bell Canada's international roaming map, aliv provides LTE coverage to CocoCay and BTC provides 3G coverage. Upon arrival in The Bahamas, my phone connected to BTC's 3G network and I got a welcome text from T-Mobile. Neither BTC nor aliv has a tower on the actual island of CocoCay. Instead, they have a tower on Great Stirrup Cay, the private island that belongs to Norwegian Cruise Lines about a mile and a half away. This is not an issue though as BTC uses Band 5 for their HSPA network and have power and downtilt set such that you get full signal across the entirety of CocoCay. I was actually getting great 3G speeds from the tower at about 12-18Mbps down and 2-4Mbps up. Ultimately I had nothing to complain about with BTC's network there. BTC 3G:

  24. I just received it in my rural town of WI. I'm a few miles down the road in a forested area, but having B71/N71 finally makes a world of difference. Before I was roaming at random throughout my yard on you-name-it carriers/Sprint 1x but now have 10+mbps. N41 is in town but appears backhaul has not been upgraded yet because speeds are no better than B2/66 before.

  25. I am on 4G most of the time also. Our service is great. We get everything we need and want out of our connection. I remember the issues we had when Sprint converted towers to LTE. Everyone was out chasing tower upgrades. It was a mess for some people but we all got thru it. And I for one, am glad we did.

  30. Staten Island Took a trip to the forgotten borough of NYC, Staten Island, to see how the n41 build was going on over there, and to be honest, its a mixed bag. Immediately off the Verrazzano, I found n41 40 MHz, being broadcasted from a different frequency. The unique thing I have found is T-Mobile does 2680 for their LTE block on the island, not the 2538.2 MHz block like the rest of the city, because the NR block is using that area. South of the Expressway there is plenty of apparent holes in n41 coverage, as I dropped to n71 often, but north of the Expressway was different, as I was on n41 more often, but still dropped down to n71 occasionally. Seems like most towers have n71 and wide enough to be on n71 often, but n41 is still very patchy. I went with the guess that 2645.8 and 2599 MHz blocks from Sprint were 20 MHz each, but they are not, they are 10 MHz and 15 MHz respectively. This places the 2645.8 block right inside T-Mobile's n41 40 MHz block in Brooklyn and The Bronx. Could also be only for Staten Island 2645.8 and 2599 are setup like this, not sure. T-Mobile is also overlapping the NR block with the 10 MHz LTE currently being used for Sprint small cells on Staten Island. Organized layout of all the active blocks I have found for Staten Island: (center frequency, bandwidth [frequency boundary] = deployment) * = same deployment citywide 2523.8, 10 MHz [2518.8 to 2528.8] = Sprint LTE small cells * 2599, 15 MHz [2591.5 to 2606.5] = current Sprint LTE macros 2645.8, 10 MHz [2640.8 to 2650.8] = Sprint LTE macros 2680, 20 MHz [2670 to 2690] = T-Mobile LTE macros 2539.35, 40 MHz [2519.35 to 2559.35] = T-Mo NR macros Finding and locating some of the towers on Cellmapper has been fun on the island, as B41 doesn't use the same PCI that B66 uses, like the rest of the city does, and B12 and B71 also don't share the same PCI either on Staten Island, so matching splits have been a guessing game if B12 isn't mapped on both the original and new eNB. Recent Brooklyn observations Verizon is moving very fast with their installations of C-band. eNBs 81426 and 81322 both have the Samsung panel Paynefanbro has shared. T-Mo has upgraded 1 of 3 sites they use to cover Starrett City with n41, eNB 43391. The site at Gateway Mall, eNB 127993, also got the 6449 treatment, so speeds on 5G have gone up there. The strange thing is, the Gateway Mall site has 2538.2 and 2558 MHz blocks, both being 20 MHz being broadcasted, along with 80 MHz n41. The n41 block and the 2558 MHz block are overlapping by ~8 MHz. I haven't found this setup anywhere else in Brooklyn yet, but it isn't the first site I have seen like this, there is a Bronx site that does the same thing, eNB 130682. I wonder if the LTE NR overlap will only remain in high traffic areas, or if it will spread across the city, as it is a ton of LTE capacity. Found 2 more n41 SA sites, eNB 134936 and 140520. The speeds leveled out at 390 down/55 up at -93 RSRP on 140520. Also don't know how long they will last with SA active, since the last 2 I knew of now have n41 SA turned off.

  31. I saw there was a thread for Central Mexico but I just decided to create a new catch-all thread for all Mexico roaming. Where I Was I visited Costa Maya Port, Mahahual, and the Mayan ruins at Chacchoben. Since I'm visiting on a cruise, I had my phone in airplane mode to avoid cruise roaming charges but as soon as we docked I turned off airplane mode and was greeted with strong signal and a text from T-Mobile welcoming me to Mexico with a message that I could use my phone at no extra charge. Networks & Speeds There were two networks available at the cruise port at Costa Maya. The first is Telcel which is the giant of the Mexican telecom industry, having the largest and fastest network in the country. The second network was the Red Compartida which is a shared network commissioned by the Mexican government that is being built out using Band 28 spectrum by a company called ALTÁN Redes so that they can bring carrier competition to the most underserved regions the country. Sidenote: AT&T Mexico's coverage map shows that they have coverage in Costa Maya Port and Mahahual but in reality it's just roaming on the Red Compartida. My phone defaulted to Telcel and even though the Red Compartida shows coverage available on their coverage map, my phone wouldn't connect to it. This is likely because it was never intended to operate as a standalone network that anyone could connect to. The fact that I was never able to connect to it was not a problem as speeds were insanely fast on Telcel. I was seeing peak download speeds of 250Mbps and peak upload speeds of around 50Mbps+ Coverage I have become so accustomed to having coverage everywhere whether native or roaming that seeing my phone drop out of coverage completely for about 30 minutes as we took the one road out of Costa Maya Port (Carretera a Mahahual) to go to Chacchoben really baffled me. The area that the highway goes through is a protected mangrove-like area with a near-zero population for about 30 miles so it's not worth it for any carrier or even the Red Compartida to actually cover. Eventually you reach Highway 307 and have contiguous LTE coverage that is super fast, with peaks speeds of over 200Mbps. According to all of the coverage maps, I should have had coverage at Chacchoben however I couldn't get my phone to connect to the network there at all. Checking the iOS network selector, I saw Telcel listed which indicated that my phone was seeing the network however it may have been too weak to establish a connection to it or Telcel's network was blocking me from connecting. Shortly after leaving there and getting back on the highway though I saw my phone connect to 3G and then LTE, providing those same 200Mbps speeds in plenty of areas that I would consider to be super rural. Summary I can see why Telcel often refers to their LTE network as 4.5G. Speeds in the Costa Maya region of Quintana Roo were insanely fast and comparable to the lowband 5G networks and the best LTE network speeds you'll find in the U.S. However, it looks like Telcel may be overstating their coverage a bit so there may be some areas where you'd expect coverage but it just doesn't exist.

  32. Yep! But that mmWave spectrum has been deployable for quite a while now - last years iPhone supported n260/n261, and so did the Galaxy series as far back as the S10. The only phone that T-Mobile currently sells that supports n258 is the OnePlus 9 Pro 5G. Having a mainstream device such as the iPhone supporting n258 will greatly increase T-Mobile's amount of deployable mmWave. Tampa, for example, would go from 600MHz of deployable spectrum to 1000MHz (400MHz n260 + 200MHz n261 + 400 n258). NYC, which is currently only operating with 100MHz of n261, will go from 500MHz of deployable spectrum to 900MHz (400MHz n260 + 100MHz n261 + 400MHz n258). Hopefully, having more deployable spectrum will push them to expand deployment.

  35. Took a day trip to Philadelphia some weeks ago, and my experience was exceptional. I was on n41 basically all the time, except when the device started to overheat and disconnect NR, as the day was hot. Rode Amtrak from NYC to Philadelphia and back, and T-Mobile was great. I locked SA south, and NSA north. Southbound the device stayed and held SA n71 without going to no signal, except for the immediate area outside the tunnel from Penn Station. From Harrison PATH station south to 30th, SA n71 didn't disconnect at all. The northbound trip was great on NSA also, quite often connecting to n41, with occasional drops to n71. 30th St Station has n41 coverage, but the tower that covers the station either is backhaul capped and/or is heavily utilized, as B66+n41 was only 110 Mbps. Walked from SEPTA Jefferson Station to the Liberty Bell, and it has 100% n41 coverage, and the tower which covers the landmark got to 600 Mbps very easily. Got on the Market-Frankford Line out to 69th Street Transportation Center, and once the train went from tunnel to elevated, n41 was there, all the way to 69th Street. Tried and failed to run a speed test at 69th St as the device was warm, thanks to the temperature of the day. Spectrum holdings Here is what I found in Center City and on the MFL trip for T-Mobile: n41 is 100 MHz, with EARFCN 516030 (2530.15 ~ 2630.15 MHz) n71 is 10 MHz, using D and E blocks B66 is 20 MHz B41 is 40 MHz, 2558 and 2538.2 MHz at 20 MHz each. B2 is 15 and 10 MHz. 15 MHz is all of C block, and 10 MHz is 1870-1880 MHz of B block. B12 is 5, and B71 is 10 MHz, B and C blocks. HSPA is still active, 1877.3 to 1882.3 MHz. Sprint: B41 at 2680 MHz (20 MHz) and 2521.1 MHz (15 MHz), and B25 (G block only) and B26. T-Mobile B41 is nearly overlaps fully with their n41 block, except for ~2 MHz. Speeds and SNR were great on n41 and B41 on the tower outside the Liberty Bell which I found it and tested on. I wonder if this is a form of DSS. HSPA is a strange one, as T-Mobile is squeezing 15 MHz of spectrum (10 MHz and 5 MHz HSPA) within 12 MHz of spectrum. I would assume come January 2022 it will be 2 15 MHz B2 blocks in Philly, with HSPA in the middle of the lower 15 MHz block, until HSPA is shut down. Data has been added to Cellmapper in Philadelphia for T-Mobile and Sprint. Album of screenshots/data is here: https://imgur.com/a/XVKgvWk

  36. T-Mobile has widened N41 to 100MHz now in the Louisville, KY area. Looks like they took the Sprint network down to a single 20MHz B41 carrier at EARFCN 41490 and they've changed the GCI pattern to 31, 32, and 33, this was previously the 3rd carrier using 41, 42, and 43 GCI endings. I noticed a decent speed boost at my house from the increase, I used to get 500-550 down about a mile from the site, now I've hit 700 a couple times. I haven't been about to test next to the site yet to see if backhaul has been increased yet, the best I've ever gotten from this particular site at 80MHz N41 was 730 down sitting right in front of it at 4am.

  39. You may need to force SA only to activate it. I have a different device (A71 5G) and I was able to make calls over n71 and n41 SA, but only by locking to SA only. Until VoNR is officially launched, the only way to use it for now is by locking the device to SA only bands. Once the device can pick up and connect to LTE/HSPA/GSM, it won't use NR for calls.

  41. Yes, in the Harrisburg PA area, I have trouble with outgoing voice on some phone calls because the upload speed is so bad. Web pages can take forever to load as well. Usually, I just give up and use my Verizon phone. Supposed to get the low frequencies on a Sprint tower near me in about a year. Currently said Sprint tower stomps on the very usable T-Mobile 5G stand alone NR signal. They just don't have the system set up properly yet.

So I have a choice of Xfinity or RCN. T-Mobile should consider striking a deal with RCN for access to fiber network, which serves Boston, Chicago, Washington DC Metro Area, NYC, Lehigh Valley and Philadelphia.

  48. It is real, they finally updated one of my locals and added 5MHz of PCS to their sites that Sprint turned from EV-DO>LTE only last year. This one has 80MHz n41, 20MHz LTE 41, 2 separate but equal 5MHz slices of LTE in PCS with a 5MHz channel of W-CDMA, 10MHz of LTE 5 with a GSM carrier in the 850 guard band, 15MHz n71, 5MHz of LTE 71 and 10MHz of band 4. There is still a shared site that has Sprint PCS A-F PowerVision kit only and Tmo LTE2/4/5 I am watching for. I hope it is next. Pretty based. Enjoy this 4K video I took of it in an opportune break between electrical storms.
