NOTE :- this thread is NOT for those ..whose mobile is having inbuilt use only 3g mode..
rests have a look on it..
Your android phone is capable of
intelligently switching between 3G and
2G depending on the signal strength. But
it’s not doing it in a smart way. Think
about a situation where you have very
strong 2G signal and very poor 3G
signal. In such case your phone will
choose 2G network.
But by experience you know that poor 3G
signals could give you much faster
connectivity that very strong 2G signals.
In such a case it would be really great if
you could stay on 3G network regardless
of poor signal. I was going through
Android menu looking for that option.
But it wasn’t there. There you have 2G
only mode, but not 3G.
It’s because this option is not there in many android phones...though some may hav it as an inbuilt option
