US Plan not working calls hang up

[ekng008]

I googled the problem and tried trouble shooting but my phone seems to be set up the way it should w LTE and roaming on. It worked for one day without issue and all of a sudden does not work today. My family who also have an account can call me but I cannot call them. Any advice on how to fix?

Hi all, so I have returned to Canada. After reading some comments here I researched a little more and tried changing the carrier from AT&T to T-Mobile and was then able to access my phone plan. However I did notice that it did not work at times when I moved around locally between neighbouring cities. It was a bit of trial and error. Where possible I did have to resort to free Wifi and connecting to Whatsapp if my plan did not work.

Ah yeah, that's the issue then. It's fine I'm Canada because your phone will fallback to 3G to make phone calls. The US shut their 3G networks down a couple years ago, so that's not an option there; instead you need to be able to use VoLTE, which your phone cannot.

If you were able to make a phone call in the US on this trip it's likely because there was a T-Mobile 2G connection in that area. You could try again to search for 2G networks, but those towers are few and far between.

Thanks for your help. I have a Google 3XL. Phone is no longer supported for updates. I guess that is why. Works fine at home and worked for one day here but no longer.

What phone do you have? And have you ensured the software on it is up to date?

@ekng008 

Which model phone?  

Certain phones (international, older phones) have recent issues with voice due to PM adjusting the 3G bands on certain areas.

You are in US?

Try to call them by +1 then 10 digits.  or 1 then 10 digits or #1 then 10 digits

@ekng008 , it is hard to say what is going on.  It would appear the problem is with your phone.  US roaming requires a VoLTE capable device for both outbound and inbound calls.  If one works, the other should as well.
