I have international  roaming available as part of plan,  but  phone won’t  connect to  internet.  I am currently  in a city  called  Coimbatore,  Tamil Nadu,  India.   The  phone connects to  a  strong  signal  from  Vodafone - India  (and  shows all bars  are up on signal anywhere in  city).   

 

But,  when i try to  start up chrome  browser,  it  immediately  shows  “NO  INTERNET”.    Has  been consistently  doing it  for past  few  days  that  i have been here.  The  obvious  checks  (Mobile data,  Data  roaming,  Network  operator etc)  have all been  checked.  So,  i am starting to  think  that  vodafone  india  is  throttling  or  cheating  Tmobile  on  their  end of the  deal.

 

If  not,  how can  tmobile  give  me  data  service  here ?  I need to get this working soon, since i  will be  india  for a while…..currently,  i am getting  by  only  on  wifi connects.

Has anyone found out where, which department, which phone number we need to complain to fix this? We cannot let T-Mobile off the hook for this. 

 

I used to know the names and e-mail addresses of the international roaming managers in Bellevue, but they have moved on to other things. Unfortunately, T-Mobile is (IMHO) really bad about passing customer complaints to the appropriate management. Bellevue seems to almost exist in a bubble.

I just landed in India a week ago and have been experiencing the same problems described by others here.

Phone shows LTE/4G full bars, and “Connected” in network status, but there is an exclamation point over the indicator icon, and all apps claim no internet available.

However, while trying different apps, I opened my work VPN (Cisco) and it gave a more detailed error message than just “no internet”, it said “DNS name lookup failed”.

Unfortunately, I did not have a terminal/ping utility on my phone, but using hotspot I was able to connect my laptop and behold, there was internet, but no name resolution
ping/nslookup google.com fails
ping 8.8.8.8 worked fine

With that info, I changed the settings on my laptop to use google’s dns server (8.8.8.8) and had internet working at that point, albeit just via hotspot.

I could not see a way to force use of a specific DNS server on my phone (Pixel, android 12) for mobile data, just in manual wifi settings.
The private DNS feature only accepts a hostname, not an IP address, and so that too fails, since it can’t look up the new server to switch to in the first place… a bit of a silly limitation, I think.

Before India, I had been in Japan and Singapore, and had no issues with roaming at all.
So it seems that T-mobile’s own roaming data settings may have a DNS server that is often blocked within India for some reason.

Hopefully this helps some of you too, and maybe T-mobile can help fix this soon.

 

A quick follow-up:
I found a few apps on the google play store that let you use any DNS server you wish, by creating a minimal vpn connection on the device itself.
These send the DNS requests to your server of choice, while just passing through all remaining traffic.

I settled on Nebulo (because it was free with no ads or purchases)

and now have working internet over mobile data on my phone when it is enabled.

 tried nebulo, but perhaps I am not doing it the right way. can somebody provide clear instructions?? i dont see any LTE/data bars, so pretty sure its not just DNS issue. perhaps ninjit’s scenario was different

city: Bhopal, India.

cellular connectivity VI (vodaphone). good
actual network: VI India 3G
however, no data connection (and tmobile connectivity chart is deep purple, and deep fake!!)

The same developer has an older app that I found worked a bit more reliably than nebulo

Try that one
