T-Mobile supports various wireless network technologies, as described below. It's important to use a device capable of the network type you desire, and be in a location that has cellular network coverage.
Check out our coverage map to see what areas we service, and check out Devices for device specifications. If your phone is having problems connecting to a network it supports, see Network connection troubleshooting.
VoLTE (Voice over LTE) allows you to place and receive calls on our LTE data network. Phone calls are connected with a clear and rich experience. You never know when you might need to check Facebook while talking to your mom and sharing your Mobile Hotspot with your friends. All of this is possible on our amazingly fast 4G LTE network. Here's some of the highlights:
T-Mobile's advanced 4G LTE network is smoking fast! With incredible speed, you can do more using our nationwide 4G LTE network. 4G LTE delivers up to 50% faster speeds then 3G. If you're in an area served by 4G LTE, you can expect blazing fast speeds because of our expanded capacity. Check out our coverage map to see all the places we have 4G LTE.*
Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz)
With 4G, theoretical maximum download speeds range from 21 Mbps up to 42 Mbps. You can take advantage of incredibly fast download speeds, and even use voice and data services at the same time.
Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)
This network type is also referred to low-band spectrum; it adds increased building penetration as well as covering greater distances. T-Mobile uses this network type in metro areas to improve in-building coverage and in rural areas to improve our LTE footprint.
Frequencies: Band 12 (700 MHz)
L1900 is used primarily to update our current 2G towers to LTE. Many of our current LTE devices already support L1900 band 2. Check out this device list for compatible phones.
Frequencies: Band 2 (1900 MHz)
With 3G, there is a theoretical maximum download of 14 Mbps. With 3G, you can use voice and data services simultaneously.
Frequencies: Band 4 (1700/2100 MHz)
EDGE, our enhanced 2G service, delivers a theoretical maximum download speed of 236 kbps. GPRS, our 2G service, delivers a theoretical maximum download speed of 114 kbps. Typical speeds are between 35 kbps and 45 kbps. Keep in mind, voice and data services cannot work simultaneously when on GPRS or EDGE.**
Data speeds vary depending on its operating system, processor, battery life, running applications, peak theoretical speeds, and distance from the cell site. USB laptop sticks almost always offer higher speeds than smartphones, because they use the power of a laptop with larger batteries, processors, and other technologies. Also, downloading information is faster than uploading. There is no way to predict an exact speed with so many factors affecting your experience.
*Not all LTE frequencies are available in all T-Mobile coverage areas.
**For the best experience, we recommend using streaming services over 4G and 4G LTE.
