So I got Verizon Flip 4 ( for insanely crazy deal from offerup), I put in my Cricket sim card and everything works except few minor things. I cannot check imei by dialing *#06#, gives error "Connection problem or invalid MMI code", visual voice mail doesn't work. From what I remember, Verizon has some deal with Samsung such that all their phones are actually unlocked and gets rebranded based on the sim card you insert, I was successfully able to do this on S10's, however on Flip 4 didn't really rebrand however everything works except few things that I mentioned. Wondering can someone shed some light here? Do I need to flash this with custom software?
