Unlimited data explained.

Work from your own contract.

Unlimited plans can still have traffic management, tethering policies, roaming fair-use limits or speed tiers.

Read the acceptable-use terms and test coverage where you actually use the phone.

1. Identify the provider, plan name and date of your current agreement.
2. Check the full postcode, device compatibility, pricing and the current provider terms that apply to you.
3. Save a copy of the written answer before changing or cancelling the service.
