No, we apologize. This is CDMA only. It's not GSM. It's for Metro PCS only. Thank you,ClaytonMobilekarma

As far as I know and I've done extensive investigation on this matter, no. For further explanation, this phone is not GSM, it is CDMA, a proprietary system that may be more secure, but cannot be used on another carrier and cannot be unlocked. See http://www.pcmag.com/article2/0,2817,2407896,00.asp for further details.

The CDMA has to be unlocked. The GSM works if you put the network setting to automatic.

no it has to be a GSM phone, the kind that runs with a sim card. This is a cdma phone. Do a little research on these two bands and you will understand a little better. It took me awhile to figure it all out but havent went wrong yet!

No, this phone is capable just for 2G and 3G, GSM and HSDPA networks respectively. For 4G you need a phone capable to operate in CDMA network.

This phone works beautifully on cdma verizon. As far as gsm service provider I am not sure. I hope this is somewhat helpful.

Yes, it is GSM and 3G phone. Also, since it's a dual phone, one SIM can be GSM and the other 3G, even from different companies.

It is a GSM phone. Like others have said, you'll have to check with Verizon.

This is a sim card phone, the carrier has to be GSM and as far as I know TMobile has GSM but AT&T; is CDMA, personally I use simple mobile, it is a spin off company (TMobile based), check with the store

If you read the description here and for the black phone, it's Verizon on CDMA and unlocked for GSM use, which is mostly international, such as western Europe.

GSM is a radio network for AT&T & T Mobil cell phones And page plus & Verizon radio network is CDMA A locked phone has nothing to do with GSM or CDMA The lock is in the phone. it is a security code the owner establishes in the phone
