I have 2 sonoff g1 device. I used them perfectly about 2-3 mounths. Then suddenly they gone offline. I did every thing in manual but every thing. It didnt work. then I realized that there are a limit of using foreign gsm deviceses ( IMEI number restriction )
I think if I change the IMEI number of G1 they will work. But how?
How can change the IMEI numbers?
Are G1 has IMEI number?
sorry for my bad english
