advice sought on how to remove back

Hello manicmike,

i'm not so sure why you want the back removed, but if it is to put in the SIM Card, you're at the wrong place. 

The Doogee BL5500 Lite has no removable back, you'd have to use the SIM needle to open the SIM Tray on the left side of your phone. Just take the needle and put it into the small hole there, a little drawer will open up where you can put in your SIM and an SD Card. On the drawer is a little picture when you pull it out, showing how the SIM and SD should be laid in.

Greetings,

Isabel
