Since beginning I bought, I had problem with 2g/3g network. It was difficult to switch between them. After few months 2g/3g network stopped working completely. However, 4g network works properly. I tried to update to newest 184.108.40.206G but it didn’t help. Can you give me some idea? Thank you
2g/3g mobile data network doesn't work
I have almost the same problem with 3g/4g network. I’ve watched some videos and there people are saying that we should go to advanced mode of settings and to try to turn off some frequencies. For some it helps for some doesn’t. I’ve given my phone to a service center in order to conduct the examination from their side. After they will give me a conclusion. I’m waiting for the conclusion. Also read that updating to 220.127.116.11 helps and the problem disappears.
