Comment:

 hi jonquark,
 thanks a lot for providing log file and your local network registration
 information to us. That is very useful. Also, could you provide us more
 information about your phone?

 1. can these O2 sim cards register to GSM network from other phone
 normally?

 2. from 3GPP TS 27.007 spec, +CME error 13 means 'SIM failure'. +CME error
 10 means 'SIM not inserted'. if there is network problem, you would get
 other error code. Like +CME error 30 means 'no network service', +CME
 error 32 means 'network not allowed - emergency calls only'.

 since you get error code 13, it looks like SIM card problem. Are these 3
 cards all failed? and get the same error code?

 3. if you know how to send AT commands, you may try to type these
 commands.

 a. retrieve GSM firmware version
 AT+CGMR
 b. retrieve IMEI code
 AT+CGSN
 c. enable network registeration
 AT+CREG=2
 d. connect to a network automatically
 AT+COPS=0

 if you'd like to know more about GSM and AT commands, you may read this:
