SMS Gateway - TextAnywhere

The TextAnywhere SMS Gateway delivers SMS messages internationally. 

Incoming Messages/Replies

You can download incoming messages manually via the Account Details screen. Simply enter the date range you wish to download messages between and click the Get Incoming Messages button:

Any incoming messages to your TextAnywhere number that have not been previously downloaded will then be downloaded. You could also setup a FileMaker Server script schedule to have this run on a scheduled basis (e.g.every hour) to save you from having to manually download/check for new messages - your script would just need to handle the incrementing of the timestamps.
