PLMN of TMobile Puerto Rico

Hola,

Could anyone help me to find out the correct PLMN of T-Mobile in Puerto Rico currently? I have found 2 different answers on internet: 310.260 or 330.490 (See attachment). 

Gracias.

  • Hey there. I had to reach out on this one to find the answer because I had never been asked this question. Currently, the primary PLMN for T-Mobile mobile customers in Puerto Rico is 310-260, although other PLMNs are still used by T-Mobile in Puerto Rico.

    Hope this clarifies things for you. :)

    You may want to check with T-Mobile directly.

    Puerto Rico is a US territory, it is basically treated as such by T-Mobile, and has 5G / 5G ultra capacity and isn't considered 'roaming'.  I suspect that it is using 310-260.

    In general, the US has multiple MCC codes (310-312 at least), and it wouldn’t be surprising if PR also has a native (local) 330 for PR only companies like América Móvil and PR Wireless.

    In the US, 310-260 is T-Mobile, while 311-480 is Verizon … diff codes.  I would say that it is unique to see MCC into different countries, but PR isn't a country, but rather a US territory.

    Hola formercanuck,

     

    Thanks for the answer. My speculation is the same as yours. 

    I have contacted T-Mobile twice. First tiem I called their customer service line, the answer provide by them is 330.30 which is an AT&T PLMN according to my first reference. 2nd time I wrote to their Apple business chat. They were not able to give me any answer. 

    So I would really appreciate if anyone from T-Mobile can help to resolve my question.

     

    Thank you for your time.

    They could actually use both under the same network, just as Sprint had at least 3, with 1 under 310-120, and one under 311-490 and 312-250.

    When roaming on Sprint, the code would change between 310-120 and 311-490.  Same network, different code used.
