Hi all, I bought a Taiwanese Android ICS tablet called MyTab. I have loaded my SIM card in it and have created a profile with a new APN for accessing internet through my tab. But the problem is, I am not getting 3G speeds (same SIM on my phone says have 3G). So I checked in the settings and I see that the 'Use only 2G networks' is always checked no matter how many times I unchecked it. What's the problem here? How do I get 3G speeds? Thanks a lot!
