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

I would go to the Sprint store and have it looked at. New sim card might be needed

Any hope for VoLTE roaming?
Yes not going to have any choice when VZW CDMA roaming goes away. I wish it was sooner to force this on Sprint. It's never made since that TMobile roaming didn't include instead of VZW 1x

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.

Yeah cause VZW roaming has limits which no one wants. Those two don't

The T-Mobile roaming agreement doesn't include VoLTE. 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.

I'm sure it's not hard to add VOLTE agreement. Don't wanna be roaming onto TMO then switch to att during a call

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.

This is cool.  I didn't know this was a thing.  Wonder if this is what VZW is doing. Do you happen to know what 3GPP Release this became a feature and if it has a specific name?

I don't want my 3G trimmed down. I get 2.5Mbps over it! 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.

Verizon is doing that here. 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.

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.

Any update on CDMA sunset?

I have not heard anything. Only that non-volte devices won't be allowed on the T-Mobile network...

https://www.androidpolice.com/2020/07/25/t-mobile-will-soon-require-volte-on-all-phones-incomopatible-devices-kicked-off-january/

AT&T has announced Feb 2022 https://www.att.com/support/article/wireless/KM1324171

Verizon to end CDMA Jan 2021 IIRC...

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.

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.

    • Long live Wimax, Clearwire, Sprint Spark, Sprint LTE Advance, Sprint LTE Plus, Sprint!
    • Has your site been upgraded? Because B4/B66 performs worse on the new Nokia AAFIA Massive MIMO equipment in Texas. Before the upgrades, T-Mobile physically split sectors for B2/4/66 and coverage+performance was pretty impressive. B4/66 coverage was actually very close to that of B2 (even outperforming it in some instances). Now that my local tower has been upgraded, I still receive B12 and B2 from it. But my B4/66 now comes from a different neighboring tower as my home tower's B4/66 is drowned out. As you can imagine, I no longer get the same peak speeds as before since CA doesn't play nice with bands coming from different towers. Even the newly added B41 has a better reach than B4/66 (getting 80+ mbps downloads on B41+B41, T-Mobile just needs to optimize load balancing as B41 thresholds seem very conservative).
    • I don't have the "hearing me" problem, but I bet it's network related..... I just rarely get calls and texts when people call me or text me. Telemarketers seem to always get through but never the important calls. The New T-mobile sucks just as hard as the Old Sprint. 
    • At one point i was on B66 all the time at our house, but now i almost never see Band 66.  I haven't paid attention to the PLMNs,  i will have to check.  We haven't had the issue in a few days, hopefully they have fixed whatever the issue was.  
    • It's amazing how quickly T-Mobile is integrating Sprint's network assets after the merger and putting itself on real competitive footing with Verizon/AT&T. With the launch of the 5G iPhone, uptake of new 5G devices on T-Mobile's network must be substantial. T-Mobile's midband capacity from Sprint is making a real difference in usability and speed.
