What needs to be done to use overseas with local SIM card?
Call and ask nicely... if, and only IF you have been a good long term customer, they MIGHT unlock it for you. At least that has worked with other companies in the past. Personally, I have never asked Verizon... but I don't plan on traveling overseas. Good Luck!!!
bwahahahahah bwahahahahahha
Verizon and Unlocked should never be in the same vocabulary. One theory is that Verizon was waiting for the others to get unloacked so that they could find out how it was done and then block it.. but that just conspiracy.
I just pre-ordered my S4 and asked about unlocking it. Rep told me that all LTE phones from Verizon come unlocked. So when I go on vacation I can just pop in a SIM card and start using it. The rep confirmed this is the case.
