Can't make or receive calls to other numbers on my account

We have been having this same problem on our account, on and off, for more than a year. 

Let’s be clear; this is no a device problem nor is it a roaming issue. I have the most problems getting these calls when home in my apartment, which is most definitely in-network on the maps, as is my sister's house a few minutes away. There are 4 phone lines on our account, and at times none of them can call one another without it going straight to voicemail and immediately appearing as a missed call on the receivers phone - when said receiving phone never ran - but calls from other cell phones or landlines ring the phones normally.

And between those 4 lines we have two Pixel 6's, two Samsung A32s (one of which was broken and replaced by protection plan last fall) and a Galaxy S10e. Whatever is causing this is not going to be fixed with standard device troubleshooting steps. Our account also isn't really new. We were with Sprint for years and were transitioned to the T-Mobile side of billing and account-management about 2 years ago now.

Every indication is that, for reasons I can't fathom, this is an account/network problem. And this problem got a lot worse at the end of 2023 - been basically a weekly occurrence since last October.

I had the same problem. After 4 days working with a T Mobile rep to no avail, I finally realized I had downloaded Scam Shield ( a T Mobile app), and inadvertently blocked the number. If you have this app, it's worth a shot to see if it is blocked there.

We have 4 phones on our account and 3 of them, as of the same time today, cannot make phone calls to or receive phone calls from each other.  The call will ring once and go straight to voicemail. We can make calls to and receive calls from the 4th phone on the account as well as other phones not on our account. 

 

This is not the first time this has happened, but last time it resolved within a few hours. This time it has been almost 12 hours. I went to a local store the last time it happened and they had no idea how to fix, suggested I call TMobile.  The issue resolved so I never did call, but it is back now. 

 

Has anyone else experienced this? Any ideas how to fix?  This is not a new account, it is over a year old., No recent upgrades, we all have Samsung Galaxy S22s.

My wife and I were having the same issue. She has an iPhone 15 Pro Max and I a Samsung Galaxy S24 Ultra. When she would call me it would ring 1x and go to vm, reading as a missed call on my end. We deleted each other's contact from our phone. And it worked. We saved each other's contact again. Tried it again and it works just fine now. It was terrible because at the time of me typing this, my wife is 38 weeks pregnant. She HAD TO be able to call me. Hopefully this can help someone else. 

Have you tried powering off the devices experiencing issues for at least 5 minutes each to allow them to refresh their connection to the T-Mobile network?

I paid for unlimited text unlimited calling and data I can’t make calls and I can’t even make any calls to call customer ser

As soon as I get back to the United States am switching to another carrier I can’t even call to to pay my bills which is due in two days this is very frustrating 

Have you tried logging into your my.t-mobile.com account to pay your bill that way?  You can also see if the chat is available while you are logged in or you can reach out to T-Mobile via direct message on Facebook or Twitter to make sure roaming is enabled on your account and for further troubleshooting.

and only happens while inside or does this happen while outside as well?

Yes, as best I can tell this has only happened when we're calling one another from our respective homes. Though I can't think of a reason why landline calls would come through just fine, to our cell phones in our homes, but cell calls from others on our account do not go through. And yes, in the exact same time we're having these weird down periods, I have been able to make calls to other numbers just fine, it's only calls to family members that don't go through properly. 

while connected to wifi/wifi calling or just normal mobile calls?
