A few days ago my 950XL would not make or receive calls.
When trying to making a call, it would immediately say 'call dropped'.
Everyone calling in would say the line was just busy and not offer to leave a message.
I went to ATT and they gave me a new sim card (they were quite bewildered by the phone and all the workers came over to look at it).
That does some to kinda work, although I keep having to hard reset (remove battery) the phone to keep it available to take incoming calls, 'call dropped' still pops up every now and then.
Any better carrier options? I can't help but feel like this is forced obsolescence.
I still love my 950xl and don't want to upgrade any time soon!
How long have you owned/used your XL and used it on att? Had you used any other carrier and might that be an option? Or did I miss this?
T-Mobile is an option, I'd guess. I'm haaappily and thaaaankfully stilll using my 950 daily on T-Mobile. I had seen the 950 on attt's (good-to-go/continue working) "white list" last year and posted that on these pages, though I had moved to T-Mobile in 2017. I haven't noted any changes in my T-Mobile service. I also have no knowledge, though, of any T-Mobile x-G policies or plans regarding my phone or any other phone.
Your report sounds service-related, but I fortunately haven't had enough related experience to truly know this. You may want to visit a T-Mobile shop if one is available to you, to see if they can check/test your phone. I have an angroid phone on Mint Mobile, and though that reportedly uses the T-Mobile system, their website check says it does not support the 950. I've never checked beyond that, and I haven't tried just inserting the Mint SIM, and I won't.
Hardware-wise, your battery report makes me wonder if your battery may the/an issue/cause. Do you have a backup? I am using this Taeozi as my daily battery, though an original is still my backup: https://www.amazon.com/Battery-3200...ag=hawk-future-20&ascsubtag=UUwpUvbUpU3839686
There doesn't appear to be one available for the XL at Amazon, though a different one does show there for the XL. Without experience with the battery or seller, I can't recommend it; but, I'd sure try a battery replacement.
BTW, and interestingly -though perhaps only to me, my 950 still updates regularly in the background, though I've never monitored this. Still, a couple of weeks ago I noticed that Groove artist images were appearing again on my lock screen after having lost that feature a bunch of months ago, though Groove itself has never lost any functionality that I recall. The option to activate that lock-screen feature is also back on the Groove settings page. I checked under updates, and the phone had just updated, though usually it only reads "your device is up to date" and the last check, which is always "today, x time". I note this only to encourage you to not give up on your loved XL.
Good luck getting back to our normal.
P.S.: I haven't checked for updates on that att "white list", BTW, and I don't recall checking it for the XL.
