  1. Dear sir,

    Could yu help me?

    I want to ask a quesiton.

    When I change present sim card(Tr telsim) on the module with another operator(TR ARIA)’s sim card the module registered and I took +Creg 0,1. Stat led was corrected to registration. But it was became only one time. when I power off and again power on I took unregistration codes.

     

    Could you say that wat is the meaning  "CELL_FORBIDDEN" returns from #csurv.(I attached)

     

    Please help for problem.

    Thank you. 

    1. Forbidden are all cells of other operators. 

       

      You have only one cell of your operator (mnc: 03)  with sufficient signal level (-76 dBm):

       

      arfcn: 532 bsic: 55 rxLev: -76 ber: 0.00 mcc: 286 mnc: 03 lac: 23502 cellId: 922
      3 cellStatus: CELL_SUITABLE numArfcn: 5 arfcn: 558 561 563 567 572

       

      The next cell is:

       

      arfcn: 518 bsic: 53 rxLev: -88 ber: 0.00 mcc: 286 mnc: 03 lac: 23502 cellId: 922
      2 cellStatus: CELL_SUITABLE numArfcn: 5 arfcn: 549 565 569 579 584 numChannels:
      14 array: 512 513 515 523 526 528 531 532 534 536 538 540 542 543

       

      So you have poor coverage of your GSM operator in your area.

  2. Thank you Nikolay.

     

    Forum admin’s don’t say anything. Why? I dont know. 

    I think I must buy onother module trademark.

     

    thanks very much. 

    1. My advice is first to chenge GSM operator. Only 2 suitable cells is very poor coverage and if they are overloaded, you will no have any communication, especially if you try GPRS.
