I have one at&t and one t-mobile phone from old times (contract ends), now i have a metropcs one. Im wondering if i buy a prepaid already activated sim card and add it to the phone it works for phone calls, my son have to travel for school projects and metro is not so good in the area, so i dont want to buy a new phone for that. So u think that could work, or if a buy it non-activated do i have to pay somenthing else if i add it to my phones. I see great prices on ebay for sim cards and just wanna be sure before buy it.
thanks
