How to Unlock a Network Locked Vivo Y77t Phone?

Revolutions in the telecommunication industry have introduced advancements in smartphone features and utilities. The other side of the coin is, however, not as appealing. Thanks to the different carrier services, network locking is the commonest issue of recent mobile launches. Users have reported of Vivo Y77t phones refusing to work with different carriers.

The issue limits the smartphone’s functioning to the specific carrier from whom the Vivo Y77t device is purchased.
