Activating new TMobile SIM while overseas?
I need to move four lines from Sprint to TMobile side by mid-year. Two of the phones are overseas, and users are unlikely to be in U.S. anytime soon. If I send (or bring) the new SIMS to the users ...
There’s been some debate regarding if a SIM needs to be on T-Mobile’s network to be activated or not. I’m not sure I’ve ever seen a definitive answer to the question. Since T-Mobile SIMs (unlike Sprint’s SIMs) are not locked to a particular phone, you could activate them in the US on any compatible phone, then send or carry them to Europe. The old SIMs would not work once the new ones are activated. You could also take your chances on sending unactivated SIMs to Europe to see if they can be activated there.
