[Q] T-mobile One S won't receive calls

---

Hey everyone, I just got my One S yesterday and found out last night that the incoming phone calls aren't coming through. I can receive and send text message and make outgoing calls. Any idea if this is a problem with the phone or maybe a t-mobile outage?

Why don't you call the store you got it from or call C.S you just got it so anything wrong with it could be handled with them. Have you tested it yourself calling from another phone?

I just realized that wifi calling works. I also just called t-Mobile and after 30 minutes of diagnostics they told me that there is a network outage for new activations. Since it took them so long to figure out there is a network outage, I think they are full of it.

Are you still having this issue?

My wife just emailed me saying she was trying to call me but the call wasn't going through.

I was immediately getting calls when I changed my SIM yesterday...

When I first turned the phone on and called to activate my new SIM, tmobile made a test phone call to my new phone and everything worked fine. But now that I think about it, I think wi-fi calling was active at the time. I haven't received any calls today so not sure if the issue is still there.

This happened to me when switching telco, I got a SMS from new operator with a date but no time when my number would be ported. On that day I could make calls and send SMS but not get any calls. Turns out my number had been ported to new telco without me realizing this (I was still using my old SIM since it seemed to work to me.) After changing to new SIM everything was fine. All of this was on a desire though so might not apply to you ofc

Yep, just got a new SIM card and everything is fine.

Update: The phone worked for 24 hours and now is back to not receiving phone calls. Anyone else experiencing these problems?

Sounds like you have a bad phone, call CS or take it back and demand a replacement.

Calls not coming through - possible solution

I had this problem when I first got it.

First under settings->call->Use Internet calling - make sure you select Only for Internet calls.

Now go to wifi and make sure you are connected to a Wi-Fi network - then click the More menu listed under Mobil Network (three dots). If you have wifi calling enabled, go to Wi-Fi Calling Settings->Connection Preferences and select Cellular Preferred - otherwise you won't be able to make calls when not near a Wi-Fi.

Hope this helps - it took me forever to track it down!
