I'm in Eastern Europe for three months, also lost my SIM card, how do I keep number without paying, and/or losing my great plan, while I'm gone and how do I obtain another SIM? I can't call from here btw
To keep your number you have to at least switch your plan to a seasonal hold plan which costs 15$ per month, which would mean you loose your plan. Unfortunately, this is the only way to put a hold on your account at the moment.
Depending on the plan you have and how good it is you may want to consider keeping it and just pay the full amount for the 3 months. You have to pay $15 anyways to keep your number on that seasonal hold thingy.
