I just switched from AT&T to T-Mobile. I'd like to call over wifi, as the signal strength isn't very strong in my house. But the switch under the listing of my phone number in settings > phone doesn't exist. I have lates OS. I reset the phone. Any ideas?

Hello Mintyguy,
Thank you for using Apple Support Communities.
I see you are wanting to use Wi-Fi calling on your iPhone. This is a great way to save your cell phone minutes and long distance charges. This article provides the basic of setting up Wi-Fi calling and from the article it looks like T-Movile does support it.
Make a call with Wi-Fi Calling
Regards
