About FrequencyCheck

Our Goal

To simplify the process of comparing cell phone and mobile device compatibility across countries and carriers around the world.

Why

It is becoming increasingly difficult to compare frequency band compatibility due to the constantly changing nature of frequencies used by carriers and networks. Additionally, some devices such as certain Samsung models have over 20 different variations of the same phone with different sets of frequency bands which makes it even more difficult to keep up with.

Who

This site is helpful for anyone who buy/sells unlocked mobile phones and devices such as travelers or anyone who needs access to multiple mobile networks both domestically and internationally.
