SIMCARD FAILURES
First of all – always check the mechanical condition of all connectors: X100, X101, X102 and
change if contact springs are bent, soiled or possible torn off traces/pads under X100.
Also check solderings of connectors and areas for possible liquid damages.
"INSERT SIMCARD"
Check if the phone works properly with a Test SIM.
If Test SIM works check R115, R116 (both 100 Ω ) if these are in a high Ohm range.
Check at SIMcard reader if VSIM is pulsed to 3/5Vpp, refer to VSIM picture – if not, change N100 if necessary.
Check SIM lines and especially V112 for shorts to GND.
Check components in SIM lines (R115, R116 and C137 – C141) for short circuits or capacity loss.
"SIMCARD NOT ACCEPTED"
Open with WinTesla/View/Quick-RF-info, to see if a possible SIMlock is activated.
Compare the data listed in MCC & MNC with SIMlock list for the respective product code.
If SIMlock settings are ok, but the MSIN data field is closed to any special IMSI data range:
ONLY the provider is allowed to open this SIMlock!
If the listed data does not fit to the product code:
Correct SIMlock settings with NOKIA Security Password, if this procedure is permitted to you.
If SIMlock is not active and/or SIMcard is still not accepted after correct data input – change COBBA N200
NOTE:
After rework of COBBA it is necessary to rewrite SIMlock data with NOKIA Security Password if it is permitted to you.
