No, that is not (just) a "modem" - that is a Phone!
As previously mentioned, this is the root of your problem - so don't use it!
A Phone is not an appropriate device for this application.
You need a proper GSM modem (or module) that is specifically designed for embedded use,
In fact, it is a "serious smart-phone":

Totally inappropriate!

Several here: www.8052.com/.../174430
they should all have lists of their worldwide distributors.
RS & Farnell now sell such stuff.
And there's always ebay.
And google...
