What would you like to do?
Gammu config and script for receiving SMS via a USB modem attached to an OSX computer and forwarding it into iMessage, where it will appear on all your devices.
[gammu]
port = /dev/tty.HUAWEIMobile-Modem
connection = at19200
model = at
synchronizetime = yes
logfile = /Users/me/.gammu/log
logformat = errorsdate
gammucoding = utf8
[smsd]
Service = files
CheckSecurity = 0
LogFile = /Users/me/Library/logs/gammu.log
InboxPath = /Users/me/.gammu/inbox/
OutboxPath = /Users/me/.gammu/outbox/
SentSMSPath = /Users/me/.gammu/sent/
ErrorSMSPath = /Users/me/.gammu/error/
DebugLevel = 1
RunOnReceive = python /Users/me/.gammu/forwardToIMessage.py +447700900000 NZ
CheckBattery = 0

Idea (swap out the countries & numbers):

  • You live in the UK, with a UK mobile number and an iPhone (eg. +447700900000)
  • And have a New Zealand sim card and number (eg. +6421000000), in a USB modem attached to your Mac (permanently roaming)
  • When somebody SMSs your New Zealand number, make it appear in iMessage on your UK phone
  1. Get a USB modem that works on OSX. I use an ancient Huawei E220 I found on eBay. Check it's unlocked for your SIM and can send/receive texts using the vendor's Mac software.
  2. Install Gammu via git or homebrew.
  3. Put forwardToIMessage.py into ~/.gammu, and the .gammurc file into ~. Edit the paths in the files.
  4. Manually start the daemon with gammu-smsd -c .gammurc --pid .gammu/pid, then look at ~Library/logs/gammu.log and ~/Library/logs/gammu-forwardToIMessage.log for debugging help. Send yourself some SMS messages to test.
  5. Once it's working, to start it on boot (so it will pick up messages whenever you connect/disconnect the USB dongle), update the paths in the .plist file and drop it into ~/Library/LaunchAgents, then:
    launchctl load -w ~/Library/LaunchAgents/gammu.IMessageForwarder.plist`
    launchctl start gammu.IMessageForwarder
    

Tips:

  • SMSing an iMessage number via iMessage won't actually send an SMS. Using Skype if you need to test SMS is pretty cheap and easy.
  • If you get AppleScript errors, have a go at sending to your iMessage email address rather than your iMessage number. (change RunOnReceive in ~/.gammurc)
  • Has been working under Sierra, El Capitan, and Mavericks.
