It's the network frequency that is responsible.

The chinese 3G and 4G network bands are not supported in Nigeria. Not that the phone is faulty.
The problem is in-built

I am facing same issues, but I am using a mifi modem for connection

Fact is that Vivo phones are far better than the Tecno's and infinix we have here. I am even thinking of buying a higher version of Vivo with higher configurations and use my mifi for it.

IN FACT THE USE OR EXCESS IF SNAPDRAGON IN PHONE IS GREAT LAST FOR A LIVE SPAN WITHOUT DEPRECIATING IN WORKING SPEED,WEN I FIRST GOT D PHONE I WAS COMPLAINING MAYBE OR THAT UNTIL I SAW HOW USEFUL IT IS.

then give a try,u can also buy xiaomi mi 5 but quite expensive,xiaomi note 4x is cheaper,d only advantage of d mi 5 over note 4x is maybe d ba3 and the snapdragon.
note 4x has fingerprint.
COUNTRY NAME FOR BOTH; CHINA
THEY R MARVELOUS
