It is about 3 weeks I cannot send and receive SMSs. It is Lumia 950 XL on T-mobile. I called help to T-mobile. An agent did not help, send me to tech support they did not help, opened ticket it did not help too. I've reset APN several times and reset phone but it did not help. I put SIM to another phone (Lumia 920) and was able to send and receive SMSs. So the problem is in Lumia 950 XL settings or updates.
The question is what I can set, change or check on my Lumia 950 XL?
