The phone number is a free fromat field on the SIM. Even when populated can be changed by the end user. The more reliable field should be the SIM ID. This does have an issue in that devices with handheld firmware before4.2.2 will have the SIM ID with the nibbles reversed. Frimware 4.2.2 (i.e. 8300) you should be OK. The SIM ID will be stored in pairs of digits in the upper and lower 4 bits of a byte on the SIM. The result is alternate digits need to be swaped to get the correct SIM ID. You will also need a BES that can display the SIM ID BES 4.1.3 and later are capable of that.

You will need to translate SIMID to phone number outside the BES.
