AT Commands with Hologram Dash


#1

Hi community.

I am using a Hologram Dash to send some messages via SIM card, but I have some problems with the AT Commands.

Now, I am using Hologram Dash Passthrough code, founded in Examples.

But I can’t attach GPRS.

AT+CMEE=2

OK

AT+UPSD=0,1,“click”

OK

AT+UPSDA=0,3

+CME ERROR: Service not subscribed

Can anyone help with this? Or had the same problem trying to do the same? (it activates a PDP context with the specified profile, using the current parameters)

Thanks!

Standard set of questions here:

  • Are you certain the SIM card you’re using has been registered properly?
  • Have you checked the signal level of the modem?
