Can I add a sim card from one cell phone company and add it to another?

Question

Hello, I have a razor cell phone(the provider is cenntenial) and I am just wondering if I can take the sim card in that phone and add it to phones from diffrent companys..like cenntenial ect.and have it work fine.Thanks for your help.

Answer 1

If the phone is unlocked, yes.

Answer 2

If the new phone is unlocked you can put your sim card into it and it Willl work.....but it will be the same phone service.
The only phone I know wil NOT WORK is a phone set up for Verizon because they do not use Sim cards. And the phone has to be unlocked. But if it does not work you can call your server and have the phone unlocked.

Answer 3

My friend does that all the time. She and her boyfriend get mad and throw their cell phones at each other (isnt that stupid) and they just go buy a cheap one and replace the sim. I tried it with a couple of mine and it wouldnt work. I think it just depends.
