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.

#73045642, 69530200

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 have never had any issues roaming in Canada.  I don't use an eSIM though but Bell/Telus, T-Mobile's roaming partner in Canada does support eSIM.  Whether or not T-Mobile's eSIM implementation is compatible with the mess Bell/Telus use, I have no idea.

    Amazing that this issue still continues. It is definitely not a problem with the local carrier and esims. I had the same problem in Canada and had to resort to using Airalo eSIM which worked fine for data. 
    I wonder how much revenue T-Mobile is earning from customers that spend $5 and get nothing. It's such a long process to go through the troubleshooting that eventually you just give up. 
    Everything points to this being a coding issue and no one thinks it’s important enough to spend some time and resources to fix it.

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

    More Troubleshoot for this Kind of Issue

    https://community.t-mobile.com/network-coverage-5/international-roaming-india-has-issues-38006/index2.html

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

    The same developer has an older app that I found worked a bit more reliably than nebulo
    https://play.google.com/store/apps/details?id=com.frostnerd.dnschanger

    More troubleshooting On the phone goto:

    Step1: Cellular data > Network selection : change from automatic to manual selection (or disable auto)

    Step2: Wait for list of roaming operator's to populate

    Step3: select a national operator in your area

    You may need to restart phone after step3 And recheck step3 to make sure correct operator is actually selected. Once set it should remain until next restart or airplane mode.

    Day 14th Without Data, I Called T-Mobile(Customer Service Leo) again and it went 1.5 Hr and still, data receiving is not working.
    I have tried all the Troubleshooting steps Once again. Now as per Customer Service, we deleted the e-SIM and added it again. They Clear all EMI from the t-mobile Prepaid account. So I gave the EMI from S22 Ultra again, which they registered. I repeated the e-SIM Process (now I can't change the Network Mode after adding e-SIM from 5G to LTE to 3G. The option Grayout and showing Automatic). I can see 5 Full Signal bars with Roaming signs on top of the Bar. See's LTE Option in Data, but there is no data receiving. Power Off-On has been done many times. The end result of Customer Service Confirm is most of the customer's e-SIM data is not working in Mexico or any other Country, whereas Calling and SMS are working fine, and for other customers, the situation is Vice-Versa. So Please have secondary Mobile or must have t-mobile Physical SIM if you are going out of the Country or you need to buy a local e-SIM if your Mobile does not have a physical SIM slot. No matter how much they put USD $5 add on on e-SIM or $15 Mexico/Canada Addition/Remove. it will not work on e-SIM


    My colleague has Verizon e-SIM+ Physical SIM. It's working perfectly with LTE Sign. 

    I spent around 8-9 Hours calling different Customer Services. The last one I used today was very knowledgeable and technical. So I am giving up now and will return USA Next weekend. 
    I have created this thread so that other people should avoid going through the Process again and again.

    I think that might be the case. as when I login in T-Mobile account there is no data consumption from activity tracker. but Customer Service does not tell this.

    Add on Mexico for $5 dollars more per month also does not work.

    My guess is going to be that potentially the carrier you are roaming on to doesn’t support or fully support eSIM.

    Troubleshooting Steps:
     
    I did Network Setting Reset.Airplane Mode on/off, Mobile Restart,#RON# (#766#) also tried 
    Choose Manual Network to TELCEL
    SIM is e-SIM Hence Can't Remove it.
    Romaing is On
    Network Mode is 5G/LTE/3G/2G(Auto Connect)
    I can see the LTE Data option not the LTE+ and Send Arrow is the White Solid but Receive Arrow is Blinking. But when I ran the Speed Test it Does not Find the provider and Server.

    Daily I'm spending 1 Hour Discussion to T-Mobile Customer Service. Repeating whole History again but everything end's to Zero. Since last 10 Days I'm on without data in Mexico city. Mexico.
    the 72 Hour Resolution are just mockery.

    ¡Gracias por contactarnos! I appreciate you for taking time to work with us regarding this issue while traveling. I know it's important to stay connected. I see we advised you it would take 72 hours for there to be an update. At this point its only been 2 days so we are not at the 72 hour mark and there is no update at this time I would recommend continuing to connect to wifi whenever possible while our team continues to work on those tickets. I appreciate all of your patience while we work to address this. ^JonPorter
    Sure Jon,  Will wait for another Day More

    Awesome! I do want to make sure we set proper expectations for you. When traveling internationally we aren't able to guarantee a specific level of service since you are using a international network. So coverage and data capabilities are going to vary. ^JonPorter


    -----------------------------Twitter T-Mobile---------------------------------
    Thank you for getting that completed. Great news! I do show that you are connected to the network based on the following: 
    Roaming: Mexico | Roaming internacional
    Carrier: Telcel Radiomovil Dipsa,
    I see you stated it showed LTE on the device. Have you gone into the actual settings of your device to disable the 5G option completely for the time being? ^LitaIngram
    Now I'm at LTE/3G/2G(Auto Connect)
    Let me run the Speed Test
    Same issue Speed test are not able to find the Provider and Server and showing Error


    Thank you for updating those settings. I would like to try one more option. Can you try the link here: http://theoldpurple.com 
    Based on your current location, this may help with testing things out. This sites page leaves a very small footprint and it works on even the slowest connections. 
    Can I have you try that out? ^LitaIngram

    Yes, it open t mobile web page
    but browser still shows no Internet connection

    Thank you for confirming that. I truly appreciate you allowing me to research those details for you. After further review, although it shows you as roaming on the partner network, there aren't any additional steps to take to ensure we can guarantee those connections based on the area. No additional ticketing would need to be submitted because the expected coverage per that area is to be low. I know this wasn't the resolution we wanted to give, and I truly want you to have those connections while traveling. I recommend being connected to Wi-Fi as much as possible throughout your remaining travels within that area.

    Taking our time to review all of our resources to help find any needed details or resolution is what we are all about, so I appreciate you allowing me time to research that further. Are there any other details I can help with at this time? ^LitaIngram
