As long as you don't mean two active at the same time, with one SIM card, you can put into any # of phone.
yes i know,two active phones same number only if one was in use "oh well"u wld have to wait till they ended there call not convenient however much cheaper and worth having some patients especially if u rarely used ur phone any way i guess u'd need 2 clone the sim card for that( too complicated)anyway thanx for ur response
