An AT & T GSM Sim Card work in the new Motorola ROKR E8?
My Moto Razr broke recently and asked me if I bought new unlocked ROKR E8 on eBay, if the sim card from my razr to work at it. just because the ads say eBay quad and do not know what it is.
Quadband it just means that they also work abroad. Yes, but is a Gsm Sim card work in it. All we can say with certainty what works is that despite going to make and receive calls. Internet and everything else is a strong bet locked devices. Some may go to work and some can not.
