Expiry and data rollover
Telstra starts a new recharge period when you recharge. An early recharge does not simply add extra days to the old expiry. Old inclusions remain available until their original expiry; unused data rolls over only where your plan allows it.
After expiry, Telstra describes a recharge-only period with no mobile data and restricted outgoing calls. If you do not recharge within six months, the service is deactivated and the number is lost.
When the balance looks wrong
Check these before paying again
The app shows a different number
- Check
- Which service is selected.
- Next
- Switch to the SIM you are trying to check, then compare the SMS result.
A recharge has not appeared
- Check
- The receipt, recipient number and whether the bank entry is pending.
- Next
- Refresh the account after a few minutes; keep the receipt for support rather than repeating the payment immediately.
The phone says you have used more data
- Check
- The start date in the phone’s usage counter.
- Next
- Compare the same dates. A calendar-month counter is a poor comparison with a recharge that began partway through the month.
You expected old data to remain
- Check
- The plan name, old expiry and recharge time.
- Next
- Ask support which rollover condition applied to that recharge; do not infer eligibility from another Telstra plan.
A useful habit is to screenshot the balance and expiry before changing plans. If an allowance disappears, you then have the number, date and previous entitlement together, without having to reconstruct them during a support chat.
