Hey there,

I'm moving from a BGS2-W to the EHS8 and have an issue with sending a text message.

I set text mode (CMGF=1) then attempt to send the text with CMGS=021******,$0d (where the xx's are the rest of the phone number).  I usually just wait 500ms then send the ascii messge followed by $1d however immediately after the number and $0d I get a "+CMS ERROR: opration not supported",$0d,$0a message from the module.

The module is registered on the home network, is using the sim for storage, can make calls and can receive texts without issue. I have used the sim in a phone and it can send texts fine.  I have checked the message centre number and that's also fine.

Any ideas why I can't send SMS's?
