Hi guys,
After switching from iPhone 4S to GSmart Classical Dual Sim, I cannot connect to 3G. The phone does support 3G, so does my operator. And yes it's available in my area, as I used it before on my iPhone.
Whenever the connectivity mode is set to Auto, my phone only uses 2G (E), which is slow as fuck. However, if I switch that to 3G only, my phone no longer connects to the actual mobile service provider, and it remains out of touch until I set it back to auto. Not to mention that when 3G only mode is on, I cannot use 3G either. The phone has two sim cards, I use it on the first slot (I only use one sim card), though I tried using the second too - didn't help.
