iOS 8.3 Update - Tmobile wifi calling getting disconnected

Hi saurabh2326,

I know that dropped calls can be frustrating, but if this is happening with Wi-Fi calls, then take a look at the article below to give some suggestions on troubleshooting the issue further. You may want to look into the setting of your Wi-Fi if that is where it is happening the most.

same problem for me. Upgraded to ios8.3 on my tmobile iPhone 6plus yesterday. I have very poor reception at home and have been using wifi calling since it rolled out with no issues. Now, I see the tmobile wifi in the upper left corner. Make a call and it drops away to just tmobile, the the call drops. As soon as the call drops, goes back to tmobile wifi. Same thing for every call. Reset wifi calling, reset router, etc. still the same result.

On my 5s-32gb "T-Mobile WiFi" logo is not even on anymore. Before installing 8.3 it was working just fine. But as soon as I installed 8.3 I don't even get to see the "T-Mobile WiFi" logo on any wifi hotspot I'm connected to, no matter what I do. It simply not working anymore and like everybody else, at home and at work, t-mobile signal is almost non-existent and wifi calling is the only way.

I have noticed another problem that may be related to lost calls. Last night, every text message I sent using WI-FI calling on my iPhone 5S (also with iOS 8.3) with iMessage turned off, failed. The green sent bar went 90% to the right and then stalled and timed out. The text messages were actually received by the other party, but I got the error message that the send failed. Tried to resend repeatedly with the same results.

WI-FI calling worked great with iOS 8.2. With iOS 8.3 it's virtually useless.

VERY frustrating!

I hadn't associated my wifi calling problems with 8.3 but now I think about it it probably was around then that it started. I find a hard reset is the only thing that gets it working again, and then only for a while. Maybe 8.4 (out tomorrow they say) will help in some way - not holding breath.
