I just got a SIM from Infimobile for the T-Mobile network, but my phone is originally from Verizon. Will it work? Or do I need a different SIM?
I had a similar setup — my phone was originally from Verizon, but I ordered a T-Mobile SIM from Infimobile.
I checked with Infimobile support, and here’s what they told me:
If your Verizon phone is fully unlocked, it should work just fine with a T-Mobile SIM.
But — some Verizon phones (especially older ones) may not support all T-Mobile bands, which could affect signal or LTE/5G speeds.
What I did:
-
Ran the IMEI checker on Infimobile’s site before activating
-
Made sure VoLTE was enabled
-
And checked APN settings once the SIM was in
It worked for me, but if you notice weak signal or dropped calls, Infimobile can help switch you over to a Verizon SIM instead.
