What does a cell phone signal booster do? - A cell phone signal booster helps improve your mobile phone signal.

Who can use this booster? - This booster can be used by anyone who has poor cell phone reception indoors. It works for all major carriers in Argentina, like Claro, Movistar, Personal, and Tuenti.

The booster still enhances your 3G signal, so you will be able to make calls and use mobile internet, just like with a phone that supports 4G. 10.
