Q: Hello I am from Argentina. I wonder if the signal booster works for my country, and if amplified 2g networks. thank you.

A: In Argentina, 850/1900MHz is used as 2G and 3G for your carriers. Our signal booster WT-CP02 works on these two frequencies. It will improve your 2G also 3G. Please contact us for more information.

Q: Do I need an external antenna with the signal repeater for home use? 

A: Yes, A mobile phone repeater system is made of three main parts - a  directional antenna which is put outside and gathers the initial signal, a signal amplifier, which is responsible for boosting the signal, and an inside antenna which  transmits the improved signal to the users in the desired place. 

Q: Is the signal booster secured with any password? 

A: No there is no need for a password, it just strengthens your incoming signal, nothing private or personal about it. The booster device is plug and play with no interface. It's either on or off and anyone that is in range of the internal antenna receives the benefit.
