  1. Upload signals from your mobile device almost always die out faster than download signals to your mobile device because your mobile device with its small antennas and limited battery power cannot possibly broadcast to the network antenna with the same power that a large high power network antenna can broadcast to you. A device that supports both upload CA and HPUE uses upload CA to get faster upload speeds until the signal starts to get weak. At that point upload CA is disabled and HPUE is enabled so that rather than two quiet voices whispering quickly to the network antenna (Upload CA), you have one loud voice using a megaphone (HPUE) to talk at half the normal upload CA speed to the network antenna. If your signal gets stronger, upload CA is re-enabled and HPUE is disabled. The net effect is that you stay on usable B41 for a longer period of time. Now if you get to the point where B41 is no longer usable even with HPUE, then refer to the others in this thread who know about noise levels and how that affects signal strength.
  2. Because of HPUE devices can use a -128 signal on B41. It is the upload that is timing out not the download when you are not using a HPUE enabled device.
  3. As soon as they tried to do this, the states suing them would almost certainly ask the court for a temporary injunction preventing them from making this type of change until the court cases are settled.
  4. This a thousand times. 99% of customers do not care about maximum speed. They just want their mobile device to work properly for whatever they are trying to do wherever they are located. It is much more important to get rid of no service areas and to improve capacity at sites where capacity is maxed out causing users to get no effective data throughput than it is to win the max speed measuring contests.
  5. Most people at a Disney World resort hotel or in a Disney World park are on the free Disney WiFi. WiFi blankets the insides of the hotels and insides of the parks and works well even when the parks are at capacity. That leaves people in the parking lots, bus stops, commuting in cars, buses, etc. on the cellular networks. Sprint coverage generally good on Disney property and stays that way until you get outside Disney property. Then it sometimes get congested if you get away from the interstates.
  6. You are only this far away. Establish or increase your monthly donation and you will be there before you know it. Monthly donations really help with site hosting costs for sites with a lot of traffic and a huge number of users and posts such as this site.
  7. Magic Boxes can fall back to B25 if B41 is not available from the macro network. Sprint B25 will be combined with T-Mobile B2 and will very likely use MFBI. Using MFBI, B2 can broadcast simultaneously as B2 and B25. New T-Mobile should have a very large amount of bandwidth available for the combined 1900mhz B2/25. The big question is: will New T-Mobile reserve the 20mhz of B41 bandwidth necessary for Magic Boxes to broadcast their own B41?
  8. I expect that most of the switch-over activity from Sprint to T-Mobile will occur at device activation time with all new devices being activated on the T-Mobile network even if the previous device that is being deactivated was on the Sprint network. The only devices they will allow to be activated are those that will work properly on the T-Mobile network. This is why it is planned to take 3 years to move the users from Sprint to T-Mobile.
  9. The writer does not know the difference between a mobile data transmission standard (5G) and the frequency that standard is transmitted over and uses his own ignorance to bash Sprint. This is the definition of "Fake News". This article is wrong and should be taken down.
  10. If T-Mobile would keep the Sprint roaming agreements after they merge with Sprint, the combined company would have incredible coverage. The Sprint roaming agreements are extremely useful (and expensive) in keeping Sprint mobile devices usable in coverage holes. The T-Mobile network is a little better than Sprint's in some areas but in other areas is far worse and just goes to no service since T-Mobile currently has many areas with no roaming agreements.
  11. The VoLTE setting would not have been turned on in the backup since the backup was made from a iPhone 7. The restore on the XS, restored the settings from the iPhone 7. It was the restore process that turned VoLTE off on the XS. That appears to be a bug in either Apple's restore from backup process or Sprint's code that enables VoLTE where that code did not run after a restore.
  12. Once enabled in "Settings - Cellular - Cellular Data Options - Enable LTE - Voice & Data", it holds through IOS updates and iPhone restarts. VoLTE is enabled by default starting in IOS 12.1.1 on iPhone 8 and higher if you are in a VoLTE market but you can turn it off if you need to for any reason by setting Enable LTE to Data Only. Turning it off reverts to phone back to using CDMA 1x/3G for calling. Even if enabled, it acts as if it is disabled whenever you are not in a VoLTE enabled market.
  13. Sprint has limited which Iphone models can use VoLTE. Some hardware components are different in iPhone 8 and higher from the 7 and earlier models. Thus far Sprint has only developed the necessary VoLTE programming for the iPhone 8 and higher version. This is most likely due to the vast majority of iPhone users having those models of the iPhone and a much smaller number have iPhone versions earlier than 8. It is unknown if they will release a version of the VoLTE programming for older phones. If nothing else, you will likely be able to switch older iPhones to the T-Mobile network in the future and get the T-Mobile version of the VoLTE programming that works on some some older models of iPhone.
  14. I hope the first thing they do after the merger completes is to make VoLTE calls and LTE data work seamlessly across both the Sprint and T-Mobile legacy networks. That would require changes to the core data centers that power the Sprint network to make them operate like T-Mobile's network. Once that work was completed, both networks would be able to operate as the new T-Mobile network with all Sprint customers and all T-Mobile customers able to use all the combined LTE bands their devices were able to use. New T-Mobile would then be free to thin out the network by removing redundant sites, move antennas and spectrum around as needed, and most other work they need to do with minimal disruption to the end users. Work could simultaneously start with deploying 5G on low band and high band spectrum on sites that are going to stay running.
  15. One very important thing to remember is that the merger is not just for T-Mobile to get the Sprint spectrum and other assets. A major part of the purpose of the merger is to get the 50+ million Sprint customer base thereby giving them a much larger customer base to earn money from. I am sure they do not want to drive millions of those newly acquired Sprint customers away to their competitors by making them have a terrible network experience and they do not want to ruin their existing network by suddenly overloading it with new acquired Sprint customers which will drive both Sprint customers and T-Mobile customers away to better performing networks.
