Tengen31 Posted May 3, 2019 Share Posted May 3, 2019 i was asking about my phone stop working for phone call and tex message . What can i do since my phone was reset and it work on the cdma network since the cdma network say no new activation in that article . and i am talking as best as i can Oh I get ya. Is yours a LTE capable phone? If yes you have nothing to worried about. If not it was still work, just no prl update and will have to upgrade to LTE device when CDMA shutdown nears. If you have a LTE device then nothing to worry about. Happy Friday Sent from my SM-G965U1 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

dnwk Posted May 7, 2019 Share Posted May 7, 2019 I will be satisfied by T-mobile and US Cellular voice roaming. If they get VoLTE roaming on AT&T or Verizon will be a plus but I am not setting hopes that high. Quote Link to comment Share on other sites More sharing options...

Sprint could do VoIP on T-Mobile LTE (similar to Calling Plus) although there may be reliability issues there. We will likely see VoLTE roaming on USCC, AT&T and other rural partners as their LTE networks mature. Quote Link to comment Share on other sites More sharing options...

red_dog007 Posted November 24, 2019 Share Posted November 24, 2019 I didn't think 3G could be trimmed down far enough to fit in a guard band. Beings that VZW complete shutdown is Dec. 31 2020, ATT is Early 2022, I think we can expect Sprint's shutdown around then as well, at least a partial one. I think they could rock 1x800 for a long time. Unless they are ready for 5G on 800 and want to do 5x5 5G and repurpose the 1x800 into LTE.

It doesn't have to fit completely into a guard band. Even if CDMA overlaps with the LTE carrier, the LTE carrier an be configured to not assign resource blocks that overlap with the CDMA carrier. For example, if in a market where Sprint owns the C+G block, they could run a 20x20 L1900 carrier spanning 1975-1995/1895-1915. The default LTE guard bands would be 1975-1976/1895-1896 and 1994-1995/1914-1915. If Sprint ran two CDMA carriers that occupied 1975.125-1976.375/1895.125-1896.375 and 1993.625-1994.875/1913.625-1914.875, they could prevent the LTE carrier from assigning resource blocks in the 1976-1976.5/1896-1896.5 and 1993.5-1994/1913.5-1914 range. This leaves a 0.125 MHz guard band on either side of the CDMA carrier. With this design, you have the 94.7% (18/19 MHz available) of the capacity of a 20x20 LTE carrier as well as two CDMA carriers in a single 20x20 block of spectrum.

Brad The Beast Posted November 24, 2019 Author Share Posted November 24, 2019 I don't want my 3G trimmed down. I get 2.5Mbps over it! Granted it only works if you have a good signal. Quote Link to comment Share on other sites More sharing options...

Granted it only works if you have a good signal. For me personally, I don't care anymore if EVDO goes away. When I am out and about, when I actually drop down to EVDO, which is lesser these days, the signal is so weak after LTE dies off that it is completely unusable. It also used to be more useful when there was a lack of widespread B41, and LTE overall was less optimized a few years ago. When <1Mbps was fairly common, disable LTE and in town you are back up to +2Mbps on EVDO. However, I rarely even do this anymore. Quote Link to comment Share on other sites More sharing options...

By the 1x channel number it's in the middle of their 10x10 B5 carrier, and their EvDo carrier is within their 5x5 B2 carrier. 1 Quote Link to comment Share on other sites More sharing options...
TechGuru Posted December 9, 2019 Share Posted December 9, 2019 I am concerned about what Sprint is going to do about voice for iPhone's 6, 6+, SE, 6s, 6s+, 7, and 7+. Right now with my 6s my voice calls go over AT&T HSDPA when I'm outside of Sprint coverage. I'm wondering if Sprint will support VoLTE on these phones or decide to just pawn us off on AT&T for voice even inside Sprint coverage areas, which I believe AT&T plans to shut down HSDPA in 2022.

Paynefanbro Posted November 14, 2020 Share Posted November 14, 2020 They likely won’t get around to turning off CDMA until the end of next year. They’ve already migrated 15% of Sprint customers over to the T-Mobile network through software updates and device upgrades. I think that the shutdown of T-Mobile’s 2G and 3G network was moved up to January specifically to free up some spectrum in lots of cities to take on more Sprint customers. For example, they’ll have an extra 5MHz of AWS here in NYC. T-Mobile will probably take an even more aggressive approach to switching people over to their network next year because of that. 1 Quote Link to comment Share on other sites More sharing options...
TechGuru Posted November 14, 2020 Share Posted November 14, 2020 If I switch to a T-Mobile SIM (TNX) will I lose the ability to roam on AT&T? (I know I'll lose the ability to roam on Verizon 1x voice). There is a area I travel though frequently that literally has nothing but AT&T and Verizon and has been fine for me for many years with Sprint as I would always just roam on Verizon there and the past year and a half I started roaming on AT&T there instead.

Yes. Switching to TNX will cause you to lose all Sprint roaming partners. You would only have access to T-mobile roaming, and whoever their partners are. I know there is some att roaming but it's more restrictive than Sprint. And you also lose high speed international roaming. Quote Link to comment Share on other sites More sharing options...
