G400P cannot send SMS. Receiving is OK (incl. extensive logs)

Hi. I have installed one sim card on my G400P and i can make calls and receive sms's perfectly.
The only problem is I CAN NOT SEND SMS. The console command --> gsm send sms 2 6948622796 "message" worked only once for me. I have tried several times but the sms send fails.
On the CLI it says: "2:<< \r\n+CMS ERROR: no connection to phone\r\n"

I am including EXTENSIVE LOGGING from my CLI:

Hi,
Firstly, you should perform 'gsm show span X' (where X refers to span number) to check whether your gsm modem gets good GSM signal.

The message it gave "no connection to the phone" means that the GSM network is unavailable when you try to send SMS out.

I noticed that you invoke a AGI script to play audio file ‘ss-noservice’. Which tells us that the span doesn't get signal.

Hi, thanks for the response.
I don't think there is an issue with the signal because
1) gsm show span X always showed "GSM READY" and signal from 13 up to 18
2) Receiving SMS was always OK, it had not missed not a single SMS, and delivery was super fast!

Please advise me what else could be the reason. Thank you.

hello,

Could I have system remote access permission? And send invitation to my Skype: joe.yung1987

I would like to have a live chat with you then.

Hi Joe,
I have skyped you and sent you a message but you haven't responded yet. What time can i call you when you accept?

Thanks,
Elias.

my skype name is eliasbats
