I remember more than 5 or so years ago Telstra used to include international roaming in some higher end postpaid plans, with unlimited calls/texts and a monthly data allowance. Was great value for long/ frequent Int. trips.
Wish they brought back plans with such inclusions, paying $10 a day per person when travelling overseas adds up! Their latest mobile plan offerings are so tepid compared with the competition, but their domestic network coverage keeps us tied.
