Mobile as a Modem

Yeah, telstra allow you to change your browsing pack each month (or stop altogether). At least they do for the cheaper ones - I assume also for the $89 one as there's nothing on their website to suggest otherwise. Ask them when you ring to sign up

I have not seen anywhere where you can just have it for a Month, you will find it will have to be for a 12 month contract , although those little useless CDMA wireless modems if puchased outright at $499 there was no set contract,

HI Ian F, as far as i know you get charged a data rate if you you use your mobile phone for a modem, depending on which carrier you are with. Telstra will let you use there dial up service via mobile phone or if you want cheap internet get the next g wireless bb as it will work anywhere, either usb or pcmcia card with the litle o bleep y antennea they have as well for an extra $40 approx! If your with telstra then you can add it onto your bill and pay next month.

I just checked your post again , on the re-read I understand now what you mean , useing the Phone as a Modem and I presume to access Bigpond, Yes that can be done if you have a dial up plan , Instead of using the internal Modem that would normally be connected to a phone line you will use the Mobile as an external Modem , If you get a prepaid 1 month dial up from telstra and programm the laptop to use the phone as a modem ....Bobs your Uncle , ....been there, done that, keep your calls/browsing short unless your on a capped plan ie $49 will be about $250 in calls.

Thanks to everyone, I forgot to tell you I have a testra next g mobile and have used my mobile as a modem on my laptop as a test . This was using a data pack $8.00/3Mb. It worked well.
