Hi Chris,

I am not familar with GPRS, I have only used a GSM modem. The modem I have been using is the GM862-QUAD from roundsolutions. I speak very highly of roundsolutions (www.roundsolutions.com). They offer great quality products delivered to your door via UPS. They have a very repsonsive and upto date online from, discussing many aspects of their products, they have a great technical support team, should you ever need them - which will be unlikely as their documentation is written from an engineering perspective and soon gets you up and running.

May I ask whose modem you are using? Also, if you can provide me with some more details about your project - documentation, software etc.. I would be happy to take a look (I may fancy doing some GPRS work some day!). You may email me on: [email protected]

Cheers

Tom
