Conectivity with my device

Hola
My name is Gabriel and i am from Austria, visitng the USA somewhat regularly

I have a question about prepaid mobile internet and the connectivity with my device

In 2019 and 2022 i bought mobile internet devices from verizon (the 2019 got called back) that so far provided me in excellent service 

However, in 2023, when I visited the USA again, I wanted to get another purchase another 1 time pre paid plan, but this time the nice man at the counter couldn't finish the process with my European card nor phone number (which used to work fine from 2019-2023)

Thankfully a friend from the US came over and helped us out

Ever since the aforementioned events of 2023 i cannot regain acess to “My Verizon”, so i looked around to other servcice providers 

When i did an “IMEI-identification” it says :”Your device is partially compatible with the T-Mobile network—you can still use this device on the T-Mobile network, but it's functionality may be limited.”

So my question is, since I will visit this September: will I be able to bring my device to a T-Mobile store, open a new account, get a one-time pre-paid internet plan that is compatible with my current device  and pay with my European card 

I can provide an US address too, I just can't provide a US card though 

Thank you so much in advance 
Gabriel
