I have a piece of equipment with a built in modem which connects to a normal
telephone line via an RJ11 connector. I have no telephone line to connect it
to.
Soes anyone know of any piece of equipment that will allow this item to make
it's data call over my Nokia 6310i mobile phone?
Thanks,
Sean

The short answer is there isn't any. GSM, like all digital phones, do
not support true analog data- the voice compression codecs mess things
like analog modem/fax tones up pretty good.

Digital phones with "built-in modems" really don't have uilt-in
modems, but instead simply send/receive data to/from a wireless
provider who then makes an analog data connection in your stead.

A few standalone converter boxes exist that let you hook analog faxes
or modems to GSM networks
(http://www.cellantenna.com/BaseStation/telulartgsm.htm) but they cost
$500US.

Thanks for the info Todd. I was afraid that was the answer. Hate paying
bl00dy land line fees when all I need it for is a satellite decoder.

Does your provider have some workaround for no phone line? With some
cable boxes the phone line is required simply to order pay-per-view
messages. If the satellite box needs to download new information from
a central server there might be a method to force a call -- you could
bring the box to a friend, hook up to his line, then force the call.

While the phone line is used to report PPV, DBS providers also require
them to verify the receiver's location (sports blackouts, and to
"prove" your bedroom receiver is actually in the same house as your
primary, and not at a neighbor's who splits a bill with you 50/50.)

Todd has hit the nail right on the head. That's exactly the problem!

If you can get round the CLID problem, you could use your SIM in a
Nokia Premicell - if you can find one cheap somewhere.

The Premicell will give you the equivalent of a normal phone socket,
but the calls will be made on your Orange SIM. You'll also need to
make sure your SIM is data enabled.

An acoustic coupler (I'm thinking of an updated version of the old
ones that cradled the phone receiver) shouldn't cost as much as US$500
right? (For low data rate applications) Problem is the dial-out, it
may need to be done manually in some cases unless there's an exchange
that's listening for tones. Larry.

Acoustic couplers don't work with digital cell phones. The delays
caused by compression and expansion cause timing problems.

Plus, in the OP's case, he's dealing with a satellite receiver - they
call out randomly, not on a fixed schedule, so you wouldn't know
exactly when to initiate the call. Also, sat receivers have an
auto-disconnect function to drop the line when they sense another
device has picked up.
