International roaming / India - has issues

oh im sure they have data roaming over there..however they dont have to much control on forcing them to fix their towers or for them to make adjustments to their roaming...that would be on the tower owners over there to handle.

I received message on arrival that my T-Mobile plan gives data at up to 256 Kbps.. however this is false. I was never able to get Internet during the 2 weeks stay in Pune.  Even adding the 15 GB international data pass was of no use…T-Mobile is providing false and misleading information about the data roaming service in India.

My friend paid $50/month (or 4 weeks) for international roaming and was fine in major metros.  My brother-in-law travels to interior Tamil Nādu and AP.  he got a data device from a local provider and connects to Wi-Fi to that device.

He had no problems once he has latched on to the WIFI.  I do not know the cost of a wifi / data device with different providers.

Anyone found any fix for Tmobile-Vodafone coverage issue in Pune ? With E after the strong network bars, there is no connection or data flowing at all. 

I spent 3 hrs daily for 3 consecutive days with the techs on the phone trying to resolve the matter. Tried all sorts of things but no luck. They kept on saying everything looks OK on our side, so issues with roaming partner Vi. Even got a high speed data pass added to check, no luck! 

the other question is - if there are multiple roaming partners in India & Pune, why can we not manually select other partners? Ever since I got attached to Vi, it wouldnt connect to another partner even when I forced it to. Power off, keep network selection in Manual should allow other TMO roaming partners (Airtel, JIO) to register, but no, it would only attach to Vi. Looks like roaming relationship needs to be evaluated and this issue to be brought out by TMO to their partners. 

The tech team are so disinterested in actually solving the issue. They literally claim it is a signal problem with the local tower. I have another phone with an Indian plan that is getting great signal with Vi as well as data. They made me change phones and try as well. No dice.

When you complain, be sure to mention that T-Mobile’s roaming maps show service in Pune and that they should either fix the roaming or the map.

Day 2 of 2w trip and I am experiencing the same issue as reported above for Pune. when in Mimbai, I was able to connect and use data as normal, but in Pune, I see all bars but no data. When trying to connect on other TMO roaming partner manually - Airtel or JIO, get the error that cannot register. 2 years ago, this was working fine here but now the issue is very bad. Have asked TMO to issue a service request towards Vi India, hopefully they can fix the issue. 

Someone in the technical team at TMO should be reviewing these and trying to identify how to fix for international roamers as it is very difficult to manage without data connectivity

I have been a T-Mobile ONE plan user since 2017. I have successfully used international roaming in Argentina, Brazil, Uruguay, Peru, Switzerland and the UK. As recently as 2019, I used international roaming in India with the IDEA network. 
I am in India right now in a not-small-at-all city called Pune. More people live here than in Michigan. Here, I have been getting Vodafone IDEA (Vi) India Talk and Text network but no data at all. It is such a struggle being abroad and not even being able to use Uber or Maps or Translate. I am not a heavy user at all so 2G speeds work very well for me as long as I can I can travel independently and safely. However with the current situation, that's just not possible. I have had to go and buy a different Indian SIM card for my visit.

My colleagues have told me that IDEA was taken over by Vodafone India in September 2020. Maybe this change is affecting our ability to use International Roaming Data on our T-Mobile plans. 

I upgraded my T-Mobile plan to Magenta Max hoping to not have the connectivity issues I had on my earlier trips to India (Hyderabad, Pune, Chennai and Delhi). 

I just returned after spending 11 days in Hyderabad. I literally had no connectivity for 95% of my time though I was staying in the heart of the High tech City. As soon as I left Westin Hotel in the High tech City, I would see zero bars on my phone. Sometimes, I will see 3 or 4 bars but no connectivity. Outside the high tech city, I always had 0 bars on my phone. Basically I couldn't use my phone in Hyderabad without a wi-fi connection. I felt like I was living in the stone age with T-Mobile. Not sure, why I am paying T-Mobile for the Magenta Max plan for connectivity in India - I had connectivity in Delhi most times but none in Hyderabad.

I must say that T-Mobile continues to majorly disappoint its subscriber for connectivity in India. I had terrible experience on my prior trips and I thought it was due to not buying their international pass. On my previous trip, I bought the pass and had the same issue.

T-Mobile talks big about high quality and customer care but it seems that they are aware of this problem (this thread and many such threads) and have decided to do nothing about it. I would probably be switching to ATT or Verizon after my contract (new phone payments) are done.  I travel to India a lot and seamless connectivity across India is critical for me.

I am glad that I didn’t waste hours with t-mobile support based on the experience of the folks on this thread. 

Highly disappointed T-mobile.
