    I have tried using my Samsung Cricket SCH-R720 OS version 2.3.4 found to make calls and its not working just always repeating the message mobile carrier not. Another disturbing problem is that i cant find the mi-fi allocated to the phone which is broadband speed 2.8 according to the legal certificate found on it.
    Someone said that download a Driod-vpn would help but the application states that I would have to root my phone. Please what rooting app am i to use that wouldn't damage any systemic capabilities of the phone.
    My present location is Lagos state,Nigeria,Africa. My name is EZIDINMA DAVID
