We're with Telstra (it's the only company providing decent coverage in our area). We have 4 phones (2 adults, 1 for business, 1 for teen) and the other teen-to-be will be getting one soon. The minimum cost on prepaid is $30/month, so that's currently $120/month (soon to be $150/month). Does anyone know how we can get a better deal with this? Is there a way we can share credit between some of us.
