Is T-Mobile GSM
The United States is one of the only countries that limit the wireless technologies in use. America only uses GSM or CMDA, and when a person wants to switch from one technology to another, the shift isn’t necessarily an easy one. Carriers that run-on GSM networks, identify their users by requiring the use of a removable SIM card. The SIM card allows the network to track the number of users it has, and it also allows users to switch phones easily within the network.
Carriers that run-on CDMA networks track their users by embedding custom serial numbers in each of their phones. This version makes it much harder to switch devices and networks, and requires a specialist to reprogram devices for the change. Nonetheless, when the networks launched LTE, this forced all devices to use the GSM technology and required all devices to use a SIM.
Is T Mobile GSM or CMDA?
If you’re wondering what the T Mobile Network type is, you won’t be shocked to find that T Mobile is a GSM carrier. If you’re looking to switch from a CDMA carrier to a GSM carrier, you may still be able to do this with little trouble, so long as the device is LTE capable (or even a later model of iPhone). If you’re looking to switch, you will likely need to get your CDMA phone unlocked by your carrier so that it can be used with T Mobile’s GSM carrier.
T Mobile Bands
T Mobile works with technologies such as 4G LTE, 4G, 3G, and 2G. In order to have the highest network frequency for use, be sure to upgrade your device to a newer version to take advantage of the 4G LTE. The network technology that uses 4G LTE uses a frequency of Band 2 (1900 MHz), Band 4 (1700/2100 MHz). Band 12 (700 MHz), Band 66 (Which is just an extension of Band 4 at 1700/2100 MHz), and Band 71 (600 MHz).
So, what does all this mean? It means this T Mobile network type allows its users nearly 50% faster downloading speeds in comparison to 3G and allows data and voice services to work simultaneously (so long as VoLTE is turned ON, on the device). This 4G LTE also allows its users to keep a call running when switching from data to Wi-Fi calling, improved voice calling in general, quicker MMS message sending, places calls 2x as fast as 3G, and much more.
With AT&T 4G LTE bands, users are built on GSM carriers as well as T Mobile. If you’re AT&T & T Mobile phone is unlocked, you should have no trouble switching to another carrier. Verizon’s newest LTE devices can now be purchased automatically unlocked, so switching to either of the above GSM carriers shouldn’t be an issue. If you are having trouble with your T Mobile device, be sure to call T Mobile’s customer service with any questions or concerns you may have. T Mobile has made it easy to choose their networks because of their quality and #1 customer service in the nation.
