Look at the situation
Unlimited domestic data can still sit alongside speed conditions, traffic management, permitted-use terms and a separate roaming limit. Read each rather than assuming one word answers every question.
Read the conditions
For named-app benefits, check linked content, background activity, advertisements and tethering. A listed activity may receive different treatment from the rest of the device’s traffic.
Choose the next question
Use actual habits and reception needs when considering an allowance. A larger allowance cannot compensate for a device that is incompatible or a location with inadequate signal.
Keep official confirmation in view.
All explanations here are general guidance. Use your provider’s current instructions and service documents before taking action.
