Look at the situation
A useful comparison begins with where the phone is used and what it does there. Separate journeys, indoor calls, hotspot sessions and time spent on Wi-Fi. Look at several normal months so an unusual download does not determine the whole decision.
Read the conditions
The allowance is only one variable. Read the minimum term, renewal method, speed conditions and permitted use. SIM-only describes the absence of a new handset in the arrangement; it does not establish that the service has no commitment.

Save the service summary and identify the conditions you cannot yet explain. Ask the official provider to resolve them before starting. We can discuss the wording in general terms without arranging the service.
Keep official confirmation in view.
All explanations here are general guidance. Use your provider’s current instructions and service documents before taking action.
