You sure can. You can use it with any sim card carrier. It hold duel sims so u can even use two different numbers on it at once :-). Hope that helps.

This one has over 50 different brands that it works with. I don't have a carrier but it managed to work with mine. For the price I would give it a shot.

No it will not work with any carrier. It is a genuine at&t; phone not unlocked. We don't unlock phones as it might create other problems...

Being an unlocked phone I can use it here in the states with any carrier, but I am not familiar with these carriers and being a different country you may want to contact those carriers first ,

If the phone is unlocked it can be used with any carrier that accepts iPhone sims like straighttalk

Any carrier that uses a sim card (NOT Verizon or Sprint). I have T-Mobile and AT&T; installed (2 lines) and they work beautifully!

Hard to say, you really should just call them. They are the carrier and provider and would know what will or will not work on their network.

This one can use with Amy carrier. Not just lock into At&T.; However the one I bought had problem connecting to my AT&T; data network. I can call and receive call,but can't access Internet. AT&T; say they can't do anything,but later I realize it might be just some settings issue in the phone that AT&T; tech guys don't know about.

Yes you can use it with those carriers however it needs to be the STL100-1 version of the Z10.. the other versions will not work.
