What are frequency bands?

To use the mobile network, your tablet or smartphone needs to connect with a frequency range. Just like on a highway, there are different tracks that correspond to the respective frequency bands. In the USA, the 2G network, the slowest format, has been phased out and will soon be replaced by a faster band.

Not all devices can connect to all frequency ranges. For this reason, it is important to get familiar with the topic, particularly if you are traveling outside the EU.

In Europe, our data highways are built differently than in the USA. As a result, every smartphone or tablet needs to adapt to these circumstances. Newer models (starting from 2013) are often better able to do this than older models. The frequency ranges in the USA are separated into 3G (HSPA) and 4G (LTE).

Our plans with AT&T and H2O Wireless require these respective bands to function properly

What frequency ranges do I need for the USA?

There are two standards in the USA (HSPA and LTE). Data transmission requires the frequencies 850 and 1900 MHz either on the 3G (HSPA) or 4G (LTE) network.


GSM, GPRS and EDGE are no longer supported in the USA, since the network was phased out on 01/01/2017 so these frequencies could be used for network expansion.


HSPA+, UMTS and HSPA. The frequencies 850 and 1900 MHz need to be available to guarantee flawless use.


LTE. The device must be able to support the frequencies 850 and 1900 MHz.
