The screen shows "No Signal", “No Service” or “No SIM”. Why?Updated 2 months ago

With MP01, search for a network by using MENU->Settings->Connectivity->Network, then selecting Manual. The MP01 will start to look for an available signal in the area.

It is also possible that 2G signal in the area is very weak. You can check the 2G signal availability here: https://www.gsmarena.com/network-bands.php3

• If NO SERVICE is shown, this means that there is no signal.
• If NO SIM is shown in an intermitted way, please clean the SIM connector – the metal parts. The best is to use pure ethanol to clean (no alcoholic beverages).
