FAQ 1: The deivce can’t recognize my SIM card, What should I do?

If you called the device, but with voice" Your call phone power off, can't get through, not in the service etc", the following is possible reasons. Please check it.
1. Your SIM card with a pin code for access, please unlock it first with your cellphone. Please do perpetual unlock, not temporarily
2.  Normally all the GSM device in the market only support 2G SIM card, not 3G, 4G and CDMA. But most of customers said their SIM cards are 3G, 4G, it can still work, the possible reason is that their 3G, 4G SIM card cover 2G itself.  In China we also have 3G, 4G SIM card, all of them support 2G, so the type of 3G and 4G SIM card can also work with the device. But a few SIM cards are pure 3G, 4G, not include 2G, so it will not work.
Please change the SIM cards from other carriers for try.
3. The GSM signal is weak. Please check whether the GSM signal in your house is good or not.
4. Your SIM card is no enough money or overdue.
5. You installed the SIM card, but not install well.
