Ok, I have a Galaxy Note 3 phone that I originally purchased from T-Mobile. I then switched to MetroPCS. Now I want to switch to Mint. Since I have had service from MetroPCS over 3 months, the phone is unlocked. Will there be any issues switching from MetroPCS to Mint? Is it as simple as just removing the sim card, putting in the Mint sim card, and activating the phone? Will I lose any info(caller list, etc.) on the phone when I take out the MetroPCS sim? Thanks
