Our 4G LTE Network runs on the 1700/2100 Mhz (LTE) and 850/1900 Mhz (4G) frequency bands. Any device that has a SIM card slot, is unlocked, and supports our network’s frequency bands can be used on the ZIP SIM network.

Our nationwide 4G LTE network is smoking fast, with speeds up to 42 Mbps. Not all LTE frequencies are available in all ZIP SIM coverage areas.
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)
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)
2G (GSM, GPRS, and 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. Keep in mind, voice and data services cannot work simultaneously when on GPRS or EDGE.
Frequencies: Band 2 (1900 MHz)
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.
ZIP SIM will not issue a refund if you are not able to achieve the fastest theoretical speed possible.
