When I set "celular network" / "preferred network type" to 4G (recommended) or 3G my Umi Touch is completely without signal. It only work if I set to 2G and signal is very week! Please fix it or tell how to do that. I have a Umi Iron and signal on 4G, 3G or any other is completely perfect! What happening to Umi Touch? My carrier is TIM and I'm from Brazil.
Dear,
Can you try to install your SIM card on another SIM card slot or try to install another SIM card on your phone?
Have you updated your phone to the newest ROM version V3.03-20160510?
Yes I did that. I bought a new SIM card and nothing changed. Change slot and nothing too! In my Umi Iron everthing goes well! I bought Umi Touch and I intended to use the Iron, but I think I'll have to go back to him! Umi Touch is completely useless to me! Maybe I'll find someone who wants to buy this phone that I think that is the worst phone that Umi has done.
