DOOGEE VOYAGER DG300 unlock gsm networks - el4166 - 2016-06-11
Hello,
I have a DOOGEE VOYAGER DG300. I cannot connect to any GSM network in my country. My SIMs connect normally to GSM networks in other devices. Please help me.
Thanks in advance

Your device chipset is called MT6572, perhaps searching from the chipset name may help you.
Maybe SN Write tool can solve your problem. It looks like you first have to root your phone then write your IMEI using the right databases in SN WRITE TOOL.
There is also this:
