mobile unable to register

I was having problems with unable to register with real network and sim reader on the testing branch. I was advised on the list to use master branch to sort this problem, I have done this and now I get the following. <0003> gsm322.c:829 new state 'C1 normal cell selection' -> 'C3 camped normally' <0005> gsm48_mm.c:4320 (ms 1) Received 'MM_EVENT_CELL_SELECTED' event in state MM IDLE, PLMN search <0005> gsm48_mm.c:909 new MM IDLE state PLMN search -> location updating needed <0005> gsm48_mm.c:909 new MM IDLE state location updating needed -> attempting to update <0005> gsm48_mm.c:426 starting T3212 (periodic loc. upd. delay) with 21600 seconds <0005> gsm48_mm.c:2291 Do normal Loc. upd. <000e> gsm48_mm.c:2208 Perform location update (MCC 272, MNC 02 LAC 0x4e2a) <0005> gsm48_mm.c:2342 LOCATION UPDATING REQUEST <0005> gsm48_mm.c:2364 using LAI (mcc 272 mnc 02 lac 0x8cad) <0005> gsm48_mm.c:2372 using TMSI 0x49059a60 <0005> gsm48_mm.c:914 new state MM IDLE, attempting to update -> wait for RR connection (location updating) <0001> gsm48_rr.c:5449 (ms 1) Message 'RR_EST_REQ' received in state idle (sapi 0) <000e> gsm48_rr.c:1307 Establish radio link due to mobility management request <0003> gsm322.c:4049 (ms 1) Event 'EVENT_LEAVE_IDLE' for Cell selection in state 'C3 camped normally' <0003> gsm322.c:829 new state 'C3 camped normally' -> 'connected mode 1' <0003> gsm322.c:3665 Going to camping (normal) ARFCN 47. <0003> gsm322.c:452 Sync to ARFCN=47, but there is a sync already pending <0001> gsm48_rr.c:355 new state idle -> connection pending <0001> gsm48_rr.c:1454 CHANNEL REQUEST: 00 (Location Update with NECI) <0003> gsm322.c:2947 Channel synched.
