M2700 portable WiFi not providing internet anymore
I bought a M7200 and a sim card. It provided internet for three weeks and one day it stopped connecting.
From the three lights that it has, the battery and the WiFi signal turn on but the middle one doesn't. It says connected without internet in my devices.
I've tried the SIM card in different phones and it works and has data. I've also restarted the m7200 three times and nothing happens.
I wonder why it worked for a couple of weeks and then it didn't anymore. Trying to connect to the mifi app in the phone can't be possible since it doesn't give connection (as the manual says). What else can I do?
