Ive tried researching this and cant find anything so hopefully this will save me a trip to the verizon store to talk to a rep. The family plan has an upgrade coming at the end of april, and the phone upgrade is on my bro's # but he used someone else earlier on in the year so ill be using his, now i know you can upgrade your phone using someone else's number within your plan and be fine but does this work the same way with the new 4G LTE phones seeing how theres a sim card now. EXP. Say i order the phone online, its under his number, i assume the sim card comes with your order, but is that SIM card already registered to recognize the other number being ordered online or how does this work? Would i have to do all this in store so they can set the SIM up to my number? Hope someone can answer my question so thanks in advanced.
