Buy a few days ago a bv7000 pro but it has been a nightmare since the calls are cut off and the internet is dead in none of the options (2g, 3g and 4g), a technician tells me that the problem is with the band frequencies Used in Mexico that do not match the ones that the phone brings please could help me as I can use this wonderful phone.

If your local carrier frequencies are not fitting to the phones frequencies you can not use it for mobile connection. Please check frequencies before you buy.
