Ltl Acorn 6210 Wireless Module - IMEI Code

Fig 1:  LTL-6210-MMS-05
Quad-band GSM/GPRS

A user in Turkey recently asked if I knew how to find the International Mobile Equipment Identity (IMEI) number for the wireless module fitted to the Acorn 6210MG.

I had to admit that I had no idea so I emailed the factory and at the same time dismantled a 6210 to find it for myself. I've had no reply from Acorn but I discovered the number on the white label on the back of the wireless module (see figure 1) below the first bar code.

In Turkey, and probably in other countries, private users are obliged to register the IMEI number of any GSM device brought into that country. I'm hoping there is a way of getting the information from the camera without going to the extreme of taking it apart; because this presents a real problem for users, either for the camera's warranty or getting the SIM blocked by the MPNO, which it is legally obliged to do. 

I hope Acorn will tell me if there is some way of interrogating the module, possibly by SMS, to get the IMEI number. When I have more information I will update this post.

Figure 1 shows the Acorn printed circuit board (PCB) number LTL-6210-MMS-05 which is physically located between the camera's main PCB and the rear battery compartment.

The manufacturers of the wireless module are SIMCOM.

Out of interest I have include the manufacturer's description and specifications for the wireless module below.
