Question by Dylan C: Replacement sim card and phone?
Is it possible to take an old sim card (T-Mobile for example) and put it into a phone of a new provider (verizon) and still continue verizon’s service or do I need to use the sim card that comes with the phone/plan. Also how do I know which phones will work for both services? Lastly do phones that are “unlocked” go either way?
Answer by rebbie
I don’t believe so unless the phone is unlocked. Now, you might want to check if the unlocked phone is still compatible with your new service provider. I believe they have to be on the same network. Say for example, T-Mobile works on a GSM network and Verizon is on a CDMA network. I don’t think that a GSM phone will work on CDMA so like I said, you might want to double check.
