buy prepaid t mobile card to travel to USA
Voy a viajar a USA (costa oeste) y me han recomendado que compre una sim de prepago, pero para no tener que buscar una tienda cuando llegue a LAX queria saber si podria comprarla de otra forma ; espero su respuesta muchas gracias
Thanks for reaching out! Sounds like we have three questions. How can you buy a T-Mobile SIM card? Will your phone work with a T-Mobile SIM card while you are in the US? Can you use that phone with your original carrier SIM card on our network through roaming?
T-Mobile SIM cards are available to purchase through many retailers. I don't think Walmart and Target are international so Amazon may be the best option. Just make sure you purchase a United States version and not the German version.
Network compatibility can be confusing and changes as technology evolves. Hopefully I can shed a little light on things to make it easier. Cell towers broadcast frequencies and your phone has to have the right antenna to pick up what is broadcast. When your phone picks up the frequency, the software in your phone has to be able to process it to actually send and receive calls and text messages.
- I found the specs for the oppo A54S online and it should be able to pick up 5 of the frequencies that T-Mobile uses.
- What we can't verify is if your phone is capable of VoLTE. If it does have VoLTE, then you can get the T-Mobile SIM card and use your oppo A54S while you travel. If it doesn't, then that phone would not get service with the T-Mobile SIM card.
If your cellphone provider and T-Mobile have a roaming agreement, then it is likely that you will get some kind of service while in the US. It is hard to say what will and won't work because the phone is not built with the US network top of mind. You will most likely be able to send and receive text messages and get some data. If the phone is not VoLTE capable, then calls may not go through at all with either SIM card.
It is a bit of a long answer but hopefully this helps.
is that I have already done it and they tell me that my mobile will not work, but I do not understand it because the bands / frequencies of the oppo that I have are 5 out of 6. And I suppose, I only suppose that one thing is that if I put the imei on the web from T mobile tells me that my mobile is not compatible and another that with another sim I will be able to surf the internet when I am in the US
The big thing is Tmobile has there own type of VoLte while most phones that aren't Tmobile uses the default standard. Tmobile won't activate any phones that can't use their VoLte. VoLte is being able to call and use data at the same time.

but if I consult the frequencies of T mobile with the model of my mobile it says that it will capture 5 out of 6. And I have found out that trying to buy a T mobile sim card my mobile could not couple it, that will cause my mobile does not work in the US?
Try posting this question on the XDA forum. Maybe someone there has an answer.

Thanks, I'll do that, because if I have 5 out of 6 T Mobile frequencies with my mobile and my imei tells me that T Mobile is incompatible, with another SIM from Spain with roaming in the US, will I be able to navigate without problems? Can't anyone guarantee this? thank you
you would need to confirm this with that Spanish company..LTE=4G/5g data...which for TMO the phone must be able to make data calls (voice over LTE)..since your phone does not have this it will not work with TMO..you’ll need to check with that Spanish company to see who they have roaming agreements with and if they have a IMEI checker on their end to see if your phone will work or not.
I have asked for help here because the T mobile community has put up your website, because what we do not understand is why none of the mobile phones we have tell us that the t mobile page is not compatible, and what we want to know is if The mere fact that the t mobila page says that our phones are not compatible to carry your sim, we wonder if we travel with phones with a Spanish sim card that has roaming in the US, it will work or not. thank you

I have spoken with OPPO and with the SIM card company and both confirmed that my IMEI (mobile) and SIM support Volte without any problem; please can you help me
There are a handful of VoLTE implementations, all of which are not cross-comoatible. Unless they specified it was compatible with T-Mobile USA specifically, which I doubt they will because the device isn't even sold here. Feel free to try it though when you arrive. Just don't be surprised if it doesn't work.

With all my love, I feel free, but it's hard to feel that way when you're afraid in this case that it won't work. greetings
