This also works for other android devices.

2. Click “Phone Information”
3. Click choose the Phone slot you wish to modify.
4. For Phone 1 Type EGMR=1,7,”YOUR IMEI NUMBER HERE” after AT+ and click “Send Command”
For Phone 2 Type EGMR=1,10,”YOUR IMEI NUMBER HERE” after AT+ and click “Send Command”
Don’t forget to put a space between AT+ and EGMR
It would look like this AT+ EGMR=1,7″123456789054321
