As iTWire editor Stan Beer pointed out last week, Apple has introduced dual SIM to its phones through the use of the usual nano-SIM slot and an embedded digital eSIM chip.
An eSIM is an embedded chip that is software writable, so in future users could switch mobile operators without changing a physical SIM.
This would require co-operation from the mobile carrier in question and all telcos are expected to follow the line.
"However it is something we will work with Apple to introduce for our customers in the future."
In a related development, Optus announced that it would be launching double-data deals for most of its 24-month post-paid handset plans.
The telco said in a statement that for a limited time, selected Optus My Plan Plus handset plans and My Plan Flex leasing plans would offer double data inclusions for new and recontracting customers who signed up or recontracted to a 24-month plan before 9 October.
Optus managing director of Marketing and Product, Ben White, said, “Optus is committed to offering great value plans at competitive prices, which is why we’ve launched a huge range of generous data offers across the majority of our post-paid handset plans.”
