Mexico-T-Mobile Mobile Data issue on S22 Ultra e-Sim
I’ve Samsung S22 Ultra 5G with e-SIM. Plan is Simply Pre-Paid with 10GB of Data/Month and has USD$15 for International Calling, which Includes Mexico and Canada. I came to Mexico City, Mexico on 4th Feb 2023 and soon after the Plane Land, I saw the data as LTE. Roaming is On and Manually Selected the Network TELCEL(T-Mobile partner). Now the issue is I can see the LTE Icon, but Chrome, WhatsApp and Facebook are not loading. I reset the Network setting and did a Phone Re-Start. Airplane Mode was on-off, and the Data send/receive is still not working. #RON# (#766#) also tried. I also used Speedtest to see whether data send/receive happened and in Speedtest, it could not connect the Provider and Server. The call and SMS service is working Fine. I raised 2 Tickets, one after another, with Customer Service and Engineer team and they said it would take 72 Hours to resolve. But there is no resolution.

Still depend on Wifi Service and Office Verizon Mobile Hotspot
Hello Everyone; I came again to Mexico on 15th May 2023 and thought to give it another Chance on Tmobile USA e-SIM in Mexico.
Removed my $15 International Calling Plan and Added $5 Mexico Plan Online, Message Came, and I first put the Phone in Airplane Mode and Restart the Mobile. After Restart, I turn off the Airplane Mode and enable the data with Data Roaming On and 😀WHOA😍..... I can see the LTE+ Option in the Network data. it's 4G Speed(32.8 Mbps download and 1.38 Mbps Upload), Checked in Speed test.
I came to Mexico again on 30th July 2023. it was already recharged with a $5 Mexico Data Plan. 8 Days, it worked with 5G Data, and last 2 Days it Stopped. I called T Mobile Pre-paid Customer Care and they checked everything and asked me to Select the Telcel Network Manually and It started working again.

Again Came to Mexico for 1 Week and Same issue happening You can call, Text but No data on eSIM
Yes, I sent this thread to T Mobile Customer Service so that they can forward this to Technical Engineering Team. Unlocked Mobile, Simple Prepaid Plan(Not a Magenta One)
The Final - Root Cause is in eSIM Code which is not compatible with Roaming Partner(TELCEL). where as Physicals SIM works Perfectly with USD$5 Add On.Each carrier's eSIM implementation can differ, just like how VoLTE, VoWiFi, and other carrier specific features can differ. It is going to take a long time before carrier's start to worry about their roaming partner's eSIM's.
I went to Mexico last week and as soon as the Plane landed, I chose the network Telcel and the same issue repeated. I tried all possible ways. This time I changed the DNS, but nothing worked. VPN also didn't work. hence this Proves it's am eSIM Issue.
Nebulo - DNS Changer for DNS o
DNSChanger for IPv4/IPv6
I think T-Mobile must send One Technical Person to Mexico with a mobile phone who has eSIMs with Pre-Paid and Post-Paid and they can see the issue and resolve this instead then endless calls to Customer Service and each call spending 2-3 Hours when we know nothing can come out.

Same here, I have no connection in Mexico, but my wife does have internet. Im on a esim and she is on a physical sim. The strange thing is the Im able to connect just while using a VPN but not without it. Does anyone have any idea why?
@Edkjm Yes, It's e-SIM issue, the Physical SIM has No issue. I will Re-Confirm the issue next week when I will be in Mexico. as of Now following are the details.
Tipo de tarjeta SIM - e-SIM
Servicio - PrePaid
Móvil - Samsung Galaxy S22 Ultra - Unlocked
Plan - T-Mobile prepagado de 10 GB

I think you just confirmed that it's a T-Mobile eSIM issue. The eSIM is seeing the network but only connecting with the part of the network for calls and SMS. It is unable to connect to the data side of the network. That points to a problem in the code of the eSIM. If it was a problem with the Mexican network, then your physical SIM would not have connected to the data. Hopefully, as eSIMs become the norm, T-Mobile will be forced to address this issue. Apparently, they are not yet getting enough complaints as yet.
last year when I went to Mexico with Physical SIM I did only USD $5 Recharge and it worked. This Year the e-SIM Shows everything(4G Icon,Connectivity) but No Internet. Calling and Texting working.
