Question

Dialing using ATD command, Why I can't make a call using ATD for my SIM card?

Asked by: KSN

Hi all,

When I use ATD98765432 to make a call with my SIM card, I receive NO CARRIER. However, when I use my friend's SIM card, it works! Can anyone tell me why? Would it be the difference in versions of the SIM card? What kind of SIM card should I use in order to make a call for data?

Thanks and regards,
KSN

The SIM card shouldn't make a difference.  Looks like the way you are issuing the ATD command is wrong. Try

           ATD<number>;

I don't see a semi-colon at the end of your ATD.

Also, not sure where you are calling from, but your number is 8 digits long (unless this is just a sample number).

Finally, not sure about your test environment, but the phone/modem may be locked to a particular carrier.

You can use any SIM card to make a data call - just would be better if the phone supported data call mode and appropriate error corrections (see wavecom, ericsson)

Cheers,
Mathew
