Can't send SMS message with BG600L

I’m using a terminal to try to send a SMS text message with the BG600L EVB.

When I issue the following commands and finish with CTRL-Z it just seems to lock up

NB. I am registered and can get the MQTT commands working

Can anybody advise?

Thanks, Alex

I’ve just seen I am getting a network timeout?

+CMS ERROR: 332

It’s OK apparently this is because my trial contract didn’t have SMS enabled
