ok here is the deal ... I own a Verizon droid rzr. it is a global phone I believe. so it has a sim card on it. I bought it from someone everything was clean... so I went to this place and had it flashed to page plus right.. ok I wanted to upgrade phones to the Samsung galaxy s4 (Verizon). so this is my question. how can i make the sim card to work with this galaxy s4?. i was told that i could take my droid rzr sim and put it in the galaxy s4 and i should get service.. but it doesn't!!...is there a way to get it to work ?? when i put the sim card in and try to make a call, the operator tells me that there is an error processing the call!!... so i don't know what is going on... any help would be appreciated..
