2.Error 721: Remote Server timeout

3.Error 718

Normally caused by an invalid APN set in the “Extra Initialization Commands”

Control Panel > Phone and Modems > Modems > Standard Modem > Properties > Advance

Make sure that it is at+cgdcont=1,”ip”,”celcom3g” or “unet” (maxis)

If this is true, the SIM card might be a 2G SIM card. Advice the us er to go to Celcom/Maxis to change the SIM to a 3G SIM card.

If the SIM is a 3G SIM card, try doing a hard restart.

NOTE: To confirm that it is a 2G SIM , get the user to change the “Extra Initialization Commands” to at+cgdcont=1,”ip”,”” “net” (Maxis) and initialize a dial-up. If this is successful, this confirms that the SIM is a 2G SIM because APN used is specifically for 2G SIM only.

  5. poweron_99

    I’d purchase an unlocked BB Bold 9000 from S’pore.
    And applied Celcom BIS.

    Inserted the SIM (3G) card to the device; I couldn’t makes call and sending SMS, it consistently gave “SIM Toolkit Control Error. Tried Later”. However I’m able to receive calls and SMS.

    – when I manually select the network to Celcom 2G; then I can make calls & sending SMS.
    – when I using Maxis or Digi prepaid card, I can make calls & sending SMS.

    Sounds the device is working fine; I’m suspecting the Celcom SIM (3G) provisioning issue. Any help out there?

    • Poweron_99,
      this is weird man.
      1.Maybe you can change to new SIM card.
      2.What is the signal indicated? GSM,GPRS,EDGE,3G there HRT showing? option>advanced option>host routing table
      4.option>sms>network sen over >CS?

      happy to help
