Upgrade Deals
Before upgrading, check whether you are at the end of your minimum term, whether early charges apply and whether a trade-in changes the overall cost.
Four-step check
Before you change handset
1
Check your current contract
Confirm your minimum term, remaining device balance and any early termination charges.
2
Compare the full new cost
Include device repayment, airtime, upfront cost and future published price changes.
3
Value your trade-in
Trade-in values depend on model, condition and provider rules. Do not treat an estimate as guaranteed.
4
Confirm number transfer
If moving provider, review the provider's number-porting process and required information.
What to verify
Before accepting an upgrade
- Confirm any remaining device balance or early termination charge.
- Check whether a trade-in estimate can change after inspection.
- Review the new minimum term, monthly airtime cost and device repayment separately.
- Confirm any published annual price changes and their effective dates.
