For this phone the engineer code was #*#3646633#*#
Also for those who do not know their engineering mode code download an app called "MTK Engineering Mode" I don't have a link so please search google for it. Alternatively you could download an app from the playstore called 'Mobile Uncle Tools'
1. Install "MTK Engineering Mode" then Start App
2. Then go to MTK Settings
3. Go to Connectivity
4. Go to CDS Information
5. Go to Radio Information
6. Select Phone1
7. At the top there is a command line which begins “AT+” just type there “AT +EGMR=1,7,”IMEI_1″ (Put your first IMEI number, check phone box or case for imei)
8. Hit send command and you will / may get a confirmation that "sent to mSend".
9. Now go back and select “Phone2″ (for the second IMEI number)
10. At the top there is a command line which begins “AT+” just type there “AT +EGMR=1,10,”IMEI_2″ (Put your second IMEI number)
11. Reboot your phone and check you IMEI number (Dial *#06#).
