I believe you need in MAC: Command+Shift+V
Tried cmd, ctrl, alt, anything mac related
Anyway… thats not the issue… sending did work without the GL Script Layer it seems 
Edit: Sorry I was a bit too quick with my assumption. I don’t see a OK or anything similar after hitting CTRL + Z
Try the commands I pasted in the post to test sending SMS without using GL-custom binary and see if it works.
Because you hit Enter before CTRL+Z … YOU need only CTRL+Z after writing the message!
" CMS Error 350 means that the message was rejected by a cellular operator. Possible reasons: destination phone number is invalid. no credits on prepaid SIM card."
Could sending it to the same number an issue? Trying to SMS myself
Yes! you need to send to another number!
And make sure your SMSC is set correctly:
AT+CSCA?
Different valid number
CSCA
I’ll try to contact my carrier and will update
I took a look at the o2 germany forums https://hilfe.o2online.de/mobilfunkdienste-telefonie-internet-messaging-mehr-22/bei-5g-sa-kein-sms-empfang-und-kein-sms-versand-moeglich-626511. People report SMS service issues with 5G Standalone because of firmware issues.
To be honest I have never used this feature. Why do you need to send SMS from a modem device unless you have very specific requirements.
At least now we know how to test AT commands without using GL binary 
I was just trying to help
I’m using my SIM card between my phone and router on demand.
And sometimes I have to confirm 2FA SMS, thats where I noticed this problem. I honestly never had to send anything either.
Thank you for your help! Learned a lot
then it is a valid reason!
So this is sim card carriers not supporting SMS on 5G SA?
Carrier IS supporting SMS on 5G SA.
Currently, on the basis of 5G SA, there is no problem in not using our SMS function?
I don’t understand your question. There is a problem with 5G SA SMS. Can you confirm using 5G SA SMS?
I mean, if you’re on a 5G SA channel right now
Do not use our SMS feature
Sent by AT command. Can it be sent?
