I have this black alcatel link zone that was working. the 1st 2 lights are on and the 4th is for the battery the 3rd used to light up and now it doesnt and for some reason my wifi is not working anymore. The 3rd icon is an envelope and it doesnt light up. I have tried everything. It is paid, it is updated, i have reset it, and it has been restarted what can i do?
