I recently brought a Taiwanese tab (MyTab) while I was traveling in Malaysia. Problem is it's 3G is not working. I can browse the web by inserting the SIM card, but only GPRS speeds. When I do a network search, it doesn't show the real network names available in my area, instead shows some numbers. But I can make phone calls. Can the 3G modem be locked?? What should I do to get 3G? Please help me as without 3G it's almost become useless for me. Thanks.
