so here is the update regarding my zong mbb in 4g coverage area
The device will remain in 3g mode with complete signals
I forced it to go for 4g by manual network selection mode. It entered 4g mode with 3 signals and speed was even bad than 3g.
The point is I am not at the edges of coverage area, right in the centre of it.
When I place the device outside or at higher place it automatically switch to 4g but same 3 signals.
What to do?
