Done a bit of this

Basics you need to know (Simplified):

There are two ways telephones transmit data:

a. Circuit switched This is the traditional method of using a telephone where you get a dedicated connection between the caller and the receiver and it is charged per time period.

b. Packet switched Here the data is split into packets and mixed with other users packets on shared circuits and reassembled at the receivers end. It is charged on a per packet, measured in kb, basis.

So what

General Packet Radio Service (GPRS) uses packet switching and in my experience is over priced and very expensive.

I started using mobile data before GPRS was available. I have found that using a circuit switched data calls work out cheaper. Typically to download my emails takes a minute or so and costs 10p ish. For this I get a theoretical 9.6kb * 60 seconds = 576kb. Now the reality is that a fair chunk of this is used in message overhead, but even assuming half goes on overhead that is still 288kb for 10p or 34.7p per Mb.

So how do I set up an analogue modem?

To give exhaustive setup instructions for bluetooth PDA dialup would take too much space but nokia produce Support Guide for the Nokia Bluetooth Enabled Phones with Compaq iPAQ which is available here which is a good guide - follow the set up dial up instructions.

You may need to data enable your SIM card, this will mean calling your mobile service provider and asking for the phone to be data enabled. (If they are ar$y about this say you want to send faxes from your laptop and it can only use an analogue modem). Symptoms of a non data enabled phone are once you are set up the connection is dropped just after the modem dials.

I hope this helps
