It's only fair to warn you, should you reply, that you are dealing with a serious technophobe with a seriously scrambled brain.

Please excuse any shockingly basic questions/misunderstandings I may have.
I'm keen to de-Telstrify my mobile phone if possible. My priorities are:
1. Telstra network used for best coverage in remote Tassie
2. Prepaid
3. Unlimited calls to Australian landlines and mobiles
4. Includes 13, 1300 and 1800 numbers as standard
5. Includes at least 1 GB of data/month
6. Option to recharge with a voucher rather than online or direct debit
7. Option to talk to a real person who speaks understandable English when I have a problem
At the moment, Woollies $30 /month looks like the best bet. It's what I'm paying now, except I'll get the unlimited calls I need, plus 6 times the data. Does anybody else use Woollies prepaid? Have you had glitches or problems I haven't thought of?
I'm also trying to figure out what to do about broadband access for my computer. This might be too much for me to process at the same time as the phone, but in case there's a link, I'll post it here too. I get confused as it seems most people are after mobile broadband for their phone or tablet, not their computer. I have trouble finding info on the latter.
I used to use a Telstra dongle for when I was away from home - but very expensive. Then I went to Optus for when I'm in NSW. Less useful in Tassie, plus I got caught and lost $ recharging. It was my fault - I should have known that my Mac OS update would render my Optus dongle useless, and since the kind people at the Optus shop had already applied the recharge to my account for me, I couldn't get a refund on my recharge when I found I couldn't use it. I could have paid $$ for a new Optus dongle, but as I only needed it for a week, it wasn't worth it.
I now need broadband access to use my computer in various places in Tassie. But possibly only for about 3 months a year. Any wonderful ideas?
Thanks a bunch for thoughts and patience.
