T-Mobile says my phone is locked - is it?
I bought a Sony Xperia 10 III. I have a prepaid account for $15/month. I experiment with phones so I have other phones that I can put my SIM card into and they work. This new (to me) Xperia is off EB...
¡Hola!
I wanted to share a little good news and ask a question.
The IMEI checker available on our website does now check for the VoLTE compatibility, so if you enter the IMEI of a phone that does not have VoLTE, it will tell you it is not compatible with our network.
@lsitongia When did you get your sim card? In 2020, a new sim card standard called R15 was launched. Most phones and old sim cards still worked, but new phones with 5G required the new R15 sim cards. It looks like Sony Xperia10 III was released in 2021. If you have a previous sim card model, it could explain why it works in other phones but not this one.
