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.

Although 850, 900, 1900 and 1800 have been very nearby, usually phones can not receive more than one frequency at a time, a phone that works with a band, can not receive signals from other bands. So if you want your phone to work with several bands, multiband phones need. Based on your needs, you can go to your dual band, triple or Quad set.

To reach this large buildings is low. One advantage of 1800 MHz is that the capacity is higher. This band is inactive for the cities where the density of mobile users high.
1900 is only available in North America MHz, some networks in Canada and South Africa This item is not available in Europe or Asia. 1900 MHz to 1800 MHz quite similar.
