Atd call no carrier

[apertum]

I am testing a TRB142 and I’m trying to dial out to a phone number (atd4532454332), but I’m getting “no carrier” after a rather short time (1-2 seconds). Is this supposed to work?

Hello,

It seems there might be a syntax error. You should add a “+” in front of the number.

Kind regards,

Hi,

I forgot to add that if you are making phone call using ATD “;” is necessary at the end of the command.

Command should look like this: ATD+123456789;

The phone number above was just an example. I am using this: “atd+7585040034”, and then I get “NO CARRIER” after 1-2 seconds. If I do “atd+7585040034;”, I’m getting an “OK” first and then “NO CARRIER” after 1-2 seconds.

Probably you need VoLTE to make calls if number is correct. It could be the situation if modem cannot switch to 3G or 2G to make call.

How can I verify which kind of connection I have?

Hi,

To check which connection is currently active, go to Status → Network → Mobile and look for the network type, which should appear like this:

If you want to change it, go to Network → Mobile → General and modify the “Network type”.

Best regards,
