Sms from ubuntu with UMTS stick??

It is happened!!! Due to the terrible heat the clusters where overheated.
So I did not notified because of barbeque party. Nice weather, pool, friends..etc..

I did not have wifi on phone but GSM was there. Solution in this case is GSM connection from important services.
I got some telekom huawei stick with mobile data contract.
After plugging it to USB port Under ubuntu 14.04:  you should see something like this in lsusb:

lsusb
Bus 002 Device 006: ID 12d1:1001 Huawei Technologies Co., Ltd. E169/E620/E800 HSDPA Modem
Bus 002 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0c45:6409 Microdia Webcam
Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Next step is Gammu
apt-get install gammu-smsd  

next configure it with correct ttyUSB:

/home/arm2arm# cat /etc/gammu-smsdrc
# Configuration file for Gammu SMS Daemon

# Gammu library configuration, see gammurc(5)
[gammu]
# Please configure this!
port = /dev/ttyUSB0
connection = at
# Debugging
#logformat = textall

# SMSD configuration, see gammu-smsdrc(5)
[smsd]

pin=1234
service = files
logfile = syslog
logfile = /var/log/gammu-smsd

# Increase for debugging information
debuglevel = 4
ReceiveFrequency = 300

# Paths where messages are stored
inboxpath = /var/spool/gammu/inbox/
outboxpath = /var/spool/gammu/outbox/
sentsmspath = /var/spool/gammu/sent/
errorsmspath = /var/spool/gammu/error/
 

 Warning: setup your PIN for the SIM card.
Restart the service and check the logs if it is ok:

/etc/init.d/gammu-smsd restart

If you get an error like this:

It is meaning some application holds your GSM stick.  
lsof  /dev/ttyUSB0 will shouw which program hold it.
WARNING: If you want to send SMS you should disable mobile data over the stick.
 

That's it you are done.
Let us test if we can send and recieve SMS:
from terminal try following:

echo "Test-SMS from ubuntu" | sudo gammu-smsd-inject TEXT "+49176xxxxxxxx"

Put your cell phone number and in a few second you will get the test SMS from laptop.
