GSM (Global Systems Management) Cingular also supports TDMA technology but it is the "old" technology...
Wrong... Cingular (AT&T) uses GSM, but Verizon Wireless uses CDMA
No. Cingular/AT&T use the GSM network and Sprint uses CDMA. A Verizon phone could be used with a Sprint plan but Verizon customer service will have to give an unlock code.
no
No, you can not use a Verizon provided phone on a Cingular network, unless it is an unlocked phone. Most of cell phones you get with service provider (e.g. Verizon) plans and deals are locked to that particular network and can not be used with another service provider's network unless you unlock the phone.AnswerAlso - Cingular (now AT&T) is a GSM carrier and Verizon Wireless is a CDMA carrier. Each uses different cell phone technology making them incompatable. You can use an AT&T phone and switch it to a go phone once your contract runs out or visa versa. Sometimes pay as you go phones are the best option.
you can request a "port" of your current Verizon to another carrier. There may be a additional fee involved to cover the cost of the transfer.
No, this phone cannot be used on Verizon's plans because the phone is tied to Cingulars service and is a GSM phone, whereas Verizon's network is CDMA, and cannot use the phone. Even if the phone is "unlocked", it will not work on Verizon.
No. Cingular's (now AT&T's) network and Nextel's network are incompatible.
A Cingular cellphone is a phone that is tailored or made specifically for the Cingular cellphone network. Cingular at the time had a GSM network that used a specific cellphone band to make and receive calls.
Cingular
No. Verizon's network is only available in North America. So their network becoming "unlocked" only affects the devices that you wish to use in the United States, Canada or Mexico. Europe and Africa still only have GSM networks and Verizon's network is still only going to be CDMA. Two totally different networks. The only way you will be able to use Verizon's network in Europe or Africa, is if you have a Global device offered by Verizon and you use the GSM network while abroad. However, you will be paying Verizon for all of your roaming charges.
Nope. Totally different Technology. Verizon uses CDMA and Cingular uses GSM CDMA carriers have better coverage in the United States, GSM service has a larger global footprint There ARE Hybrids out there. I think SAMSUNG makes one. But I'm assuming the question has more to do with NOT buying a new phone if you don't have to.
