Ok everyone,
This has been an issue for a while now and I have not been able to get anyone to test the possible solution.
The base issue I suspect, is that the IMEI numbers that are issued to some brands in Shenzhen are not acceptable in some countries. In USA, India and some other countries it seems that the governing body for cellular communications has become very strict about security and permitted IMEI number ranges.
It can also be caused by bad antennas or bad sim tray - so be sure to check these first.
Basically I suspect that if the IMEI has not been generated by one of the the telcos local to your country it could be blocked by the network.
To prove this is quite difficult because it involves cloning the IMEI from a WORKING CELL PHONE to the watch and testing again.
This procedure is frowned upon and even illegal in some places.
So we don’t describe the method here - but, as usual - google is your friend
If anyone wants to test this it is of course your responsibility and you accept the risks.
Search the Internet for the most recent MTK IMEI information.
Be careful!! Many of the downloads can have viruses!!!
Research the process for using the tool - it is not simple and must be used with caution. Be sure that you understand the process before trying it.
You will also need the latest FULL firmware package. The database and modem files are included in the package.
Then you need to write down the IMEI from your cell phone that works and then power it off.
Once you have changed the IMEI of the watch to number you have just got from your phone - insert the sim card in the watch and factory reset the watch.
If it boots up and works then we will know that the original IMEI is blocked.
Remember, do this at your own risk and if you have any doubts at all - don’t do it.
Please don’t ask for help with this process or link any website or software related to changing IMEI to here - it really is something that we cannot support for legal reasons.
Good luck.
Cheers
