Re: "Not registered on network" in India using Samsung S8

1 of 1 people found this helpfulRoaming problems in India are a not-infrequent complaint. Did the phone ever work in India? What is your mobile plan? (Prepaid/Postpaid?) How long have you been roaming? Have you tried restricting the network mode (e.g. 2G-only, 3G-only)? Have you checked My-T-Mobile to see if roaming has been blocked? If you can get access to WiFi, you can use WiFi Calling to contact T-Mobile's international roaming desk at +1-505-998-3793. It's a free call from your T-Mobile phone.

Hi,
I will answer your questions:
Did the phone ever work in India?
This is the first time I am using Samsung S8 in India. The last time I was traveling internationally(Turkey and India) I had this same SIM on an iPhone and even then I had to reach out to TMobile to get my phone working for this same issue. I don't remember the resolution as it was an year ago.
What is your mobile plan? (Prepaid/Postpaid?)
Postpaid Family Plan. We recently switched to TMobile One and also upgraded to get better internet connectivity mobile data on International Roaming. But it seems I have been wasting my money as I cant even call an Uber using Mobile Data.
How long have you been roaming?
5 days
Have you tried restricting the network mode (e.g. 2G-only, 3G-only)?
Yes I tried this too. For each of the options, even a basic Google Search is not possible and it would say "No Network available"
Have you checked My-T-Mobile to see if roaming has been blocked?
I can't because neither the Tmobile website not the Tmobile app is working! I am getting the following error when accessing My TMobile.
502 Bad Gateway
The server returned an invalid or incomplete response.

And you can't send or receive text messages? No cellular connection at all? You must have access to WiFi or a non-cellular Internet connection to post here. I'd call T-Mobile at the number I gave previously and/or get online to check MY-T-Mobile. This is one reason I like to travel with a backup phone with either a local prepaid SIM or a prepaid international SIM, like Piranha.

Haha, "This is one reason I like to travel with a backup phone with either a local prepaid SIM or a prepaid international SIM, like Piranha." By this you mean TMobile International Roaming is hopeless and we should all assume that it will never work and carry a backup SIM right? Awesome alternate solution. I think this should be included in the TMobile International Roaming Commercials as well lol! I just wish I had not paid so much for the International Roaming Services, I will definitely ask for money back and compensation for inconvenience if roaming doesn't work during this trip.

1 of 1 people found this helpfulNo. I mean that international roaming is so complicated, with so many moving parts, that I'm always amazed that it works at all. The only time T-Mobile's international roaming did not work for me, when it should have, is when I was in Singapore and an undersea earthquake cut some submarine cables. It was good that I had a local prepaid.
When you say, "I tried calling T-Mobile's international roaming desk.... with my VoLTE on..." did you mean VoLTE or WiFi Calling? Have you tried changing the WiFi Calling preferences to "WiFi preferred"?

Err, I think I confused VoLTE with WiFi Calling.

Hey, shwetasah! We don't want you stuck without service when you're travelling internationally. If you're not able to reach out using the dedicated international roamer's customer care line that drnewcomb2 provided, but you have internet access through other means, then our T-Force team can still securely verify your details take a look at your account if you reach out through Twitter or Facebook! We'd definitely like to take a peek at the account and make sure that all is set up for you to roam without issue.
As an aside, thank you for letting us know about the 502 gateway error you're seeing -- I'm sorry to say that it seems to be an issue that's cropping up for a few folks here, and we'd definitely like to have you report this as well when you reach out. Thank you!- Marissa

Hey Marissa,
Thanks for the informing about TForce, I have reached out to them on FB. Let's see how that goes.
I tried calling T-Mobile's international roaming desk at +1-505-998-3793 with my VoLTE on, but it still gives me the same error

Thanks for routing me in the right direction. TForce was able to fix this for me.
So, the solution is to talk to TForce and verify your account with them. They will unblock International Roaming if it was blocked and also reset the network from their end. This made international roaming work for me. And this has worked for me for both Samsung S8 and iPhone.

Hooray! I'm so glad that it's worked out. They really do a fantastic job, and we're so lucky to have a web based team with account access, especially in situations like this! Thanks for coming back to let us know, and have a safe trip!
