Exetel Mobile

For this side of the market, your getting good value for money (in Tasmania, I often outperform Telstra when comparing speed and coverage) and speeds are usually 25 - 80mbp/s even out in the country.

There is a few things to note, some handy features like activating a conference call, placing someone on hold or setting up voice mail is a chore (with no instructions provided, must go to a forum) and difficulty setting these up probably would scare many inexperienced phone users off.

With Optus, coverage isn't an issue, but phone call quality ...

Disclaimer: I do not use my phone often so the cons may be a lot worse.

Pros:
* The price is cheap!
* Customer service IS actually helpful (when you connect to someone).

Cons:
* Customer service waiting time however, is ATROCIOUS.
Phone call: 30 minutes to 1 hour waiting time.
Email: 1 and a half MONTHS waiting time....

No issues at all. They're slow to respond to emails, and to update the Exetel app (which could use some alias naming benefits, as opposed to phone numbers), but overall the actual phone service works fine. Had no issues. You can also set spend control so that if the kids hit the 2Gb, the data turns off and you don't pay any more
