Unable to place international calls

I am currently traveling in SE Asia. Have international plan. Voice calls ok to US but cannot call in-country. Tried in Japan, and now in Thailand.  Tried all the recommended actions in this thread. Frustrating as a 23 year customer

I had the same problem for 10 days during a European vacation, for the first time ever. I called T-Mobile support and wasted 30 minutes getting elevated up the chain and no one had a solution. Finally came on this thread and the solution above by Tharnax worked. Had to switch the automatic carrier off and manually select which local carrier I wanted. The fourth one worked. Amazing that T-Mobile technical support doesn't know this. 

It's amazing that you think that it's amazing that T-Mobile doesn't know this.. You must be new here? Nine times out of 10 you get someone overseas that is putting your question in on the computer in front of them and getting a generated response to tell you. If it seems like a feasible issue and they don't know, it's because T-Mobile does not want them to know or you to know for that matter. 
I can’t wait for the day to watch this company go down in flames..

Addendum to comment above. I was always able to call back to US but not to European countries.

Exactly the same issue for my wife and I.  I was in Portugal and now in Italy while my wife was in Switzerland and both phones can't make or receive calls.  Spent at least 8+ hours trying to troubleshoot the issue with various T-Mobile reps to be told at the end that this is a known issue, affecting only certain accounts and certain lines within those accounts (my daughter's phone works in Italy) where the "Data Roaming Class" or something like that.. .on these lines is not set correctly and according to this rep (Luke), the engineering team is working on this issue…. with no resolution timeline.  And by the way, we both have international passes purchased…

At the end, I was told that these phones are made to work for US market y TMobile doesn’t guarantee that they will work abroad?!?  Wow.. I never heard this before.  They should say that in their commercials when they advertise their phones.

So according to Luke, this is a network issue where Tmobile can't guarantee that phones will work since they are not made for Italian and Swiss market.  Yet, if this is the case then ALL customers should be affected since this is a network issue.  Esta NO a network issue, this is an internal TMobile customer configuration issue.  It reminds me of my former company where their in-house developed software at some point reached its limits.  It was developed for different times but since my company didn't want to invest $$$, then it was patched and patched.. and at some point it stopped working.  Nobody was able to fix it anymore.  This is exactly what I am thinking is the case here.  And yet, we depend on phones for everything.

My son is in Switzerland in a camp and my and my wife’s phones are emergency contact for them - hope nothing happens.

My wife's luggage got lost by AlItalia… and they are suppose to call her when they find it.  Of course, when you call no one picks up a phone.

The tour operators use phones to communicate meeting points…. and these tours have been booked in advance so now.. if you miss a call, you hope that they will send an email and that you will see it in time otherwise you are in hours and days of customer support calls trying to get your money back because your phone couldn’t receive or make a call.

This is a mess.  I've been Tmobile customer for 20 years and I can't wait to get back to US and switch to a different carrier.  Hope they work better but who knows.  Time will tell.

Are you using Plus format? Enter all phone numbers in plus notation (e.g. +33.1.43.12.22.22, +1-212-736-5000).

Awesome! Having another person test really helps narrow down the possible causes. 

Are you using the + or 0 before the country code, or have you tried both? 

Manually dialing the number since some are not in my contacts. And I have opened a ticket with tech support since I have another issue going on as well.

Thank you for the help so far.

I have a family member meeting me on my location that is also T-Mobile so we can definitely troubleshoot this issue.

When you are on wifi, are you using wifi calling? If so, that call goes through as if you are on the US network making those calls. When you leave the wifi, then the only option your phone has is to make a call on the international network. 

If you don't mind, can you share how you are dialing the number? Are you using the contact that was saved in your phone or are you dialing manually?

If the issue does have to do with the network side, then you would want to reach out to our customer support teams by calling +1-505-998-3793 or direct messaging us on Facebook or Twitter. They would be able to take a deeper look at the account and network side of things to get you all fixed up.
