General Gammu FAQ

Will Gammu work on my system?

Gammu is known to run on wide range of systems. It can be compiled natively on Linux, Mac OS X, FreeBSD, OpenBSD and Microsoft Windows. It can be probably compiled also elsewhere, but nobody has yet tried. On some platforms however you might lack support for some specific kind of devices (eg. Bluetooth or USB).

How to set sender number in message?

You can quite often see messages sent from textual address or with some other nice looking sender number. However this needs to be done in the GSM network and it is not possible to influence this from the terminal device (phone). Usually it is set by SMSC and some network providers allow you to set this based on some contract. Alternatively you can use their SMS gateways, which also allow this functionality.

Can I use Gammu to send MMS?

MMS contains of two parts - the actual MMS data in SMIL format and the SMS containing notification about the data. Gammu can create the notification SMS, where you just need to put URL of the data (use gammu sendsms MMSINDICATOR for that). However you need to encode MMS data yourself or use other program to do that.

Device name always changes on Linux, how to solve that?

You can use udev to assign persistent device name (used as Device). You can either use standard peristent names based on serial number (located in /dev/serial/by-id/) or define own rules:

ACTION=="add", SUBSYSTEMS=="usb", ATTRS{manufacturer}=="Nokia", KERNEL=="ttyUSB*", SYMLINK+="phone"

Better is to use vendor and product IDs (you can get them for example using lsusb):

ACTION=="add", SUBSYSTEMS=="usb", ATTRS{idVendor}=="xxxx", ATTRS{idProduct}=="yyyy", SYMLINK+="phone"

You can match by various attributes, you can figure them using udevadm command:

udevadm info --name=/dev/ttyUSB1 --attribute-walk

Various documentation on creating persistent device names using udev is available online, for example on the Debian wiki or in Writing udev rules document.

What are free alternatives to Gammu?

It depends on your phone. For Nokia or AT based phones, you can try Gnokii, but Gammu should be superior in most cases. For Symbian phone you can try using Series60-Remote, which works pretty well with S60 phones, though Gammu brings various fixes to their applet.

If you are looking for synchronisation, try using something what supports SyncML to retrieve contacts or calendar from your phone, for example OpenSync or syncEvolution.
