Alternatives to SMSSync or FrontlineSMS: GSM modems?



I’m looking around for a more reliable SMS gateway than SMSSync or Frontline SMS.

We tried SMSSync - and it worked great, except that the app unexpectedly shut down a couple of times during our testing.  I’m not sure if that was caused by the model of Android or the app itself.

I’ve been told that there’s a piece of hardware called a GSM modem that essentially does the same thing.  You can place a SIM card in it and it will relay SMS messages to / from your web application.  It hasn’t been easy to find good information on these products, and just wanted to see if anyone out there knew where to look, or had any thoughts…




You may check another solution: Ozeki NG SMS Gateway. It is quite reliable and has many features you might find useful.
