I have a Huawei P8 phone. The range works, the cards from every network work, the range is full, the Internet after cell data works, text messages come. The problem is I can't call anywhere. When he wants to make a call, there is simply silence. I did a hard reset, searched all settings, tried many solutions, changed to 2g, then 3g and it still can't be called. I saw that there was such a problem in many people but somehow I do not see a specific and good solution. I am asking for advice if someone had a similar problem and dealt with it.
