T-Mobile Voice over LTE (VoLTE)
Voice Over LTE (VoLTE) launched in Seattle on May 22 for select devices. With VoLTE, you can make or receive calls on our amazingly fast LTE network.
- Calls remain on LTE network for data; no drop to 4G/3G
- Voice quality improvement
- Faster call connection time
T-Mobile 4G LTE
T-Mobile's advanced 4G LTE network is smoking fast! With incredible speed, you can do more using our nationwide 4G LTE network. Check our 4G LTE markets to see if you're covered.
- T-Mobile’s 4G LTE network uses 1700 MHz and 2100 MHz frequencies. You'll need a phone that supports LTE 1700 MHz and 2100 MHz frequencies. Check Tech Specs to view your phone's capabilities.
- Once you're registered on our 4G LTE network, you can take advantage of incredibly fast download speeds.
T-Mobile 4G (HSPA+)
- With 4G, theoretical maximum download speeds range from 21 Mbps up to 42 Mbps.
- Our 4G network operates on the 1700 MHz and 2100 MHz frequencies. We use 1700 MHz and 2100 MHz frequencies to use voice and data services. You'll need a phone that supports 1700 MHz and 2100 MHz to connect to our 4G network.
- Once you're registered on our 4G network, you can take advantage of incredibly fast download speeds, and even use voice and data services at the same time.
T-Mobile 3G (HSPA)
- With 3G, theoretical maximum download of 14 Mbps.
- Our 3G network operates on the 1700 MHz and 2100 MHz frequencies. You'll need a phone that supports 1700 MHz and 2100 MHz to connect to our 3G network.
- On our 3G network, you can use voice and data services simultaneously.
T-Mobile 2G (EDGE)
- 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.
- 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.
