Inside this article 3 sections
01 / Decisions
SIM-only
SIM-only supplies connectivity and an allowance without necessarily adding a handset. It can still involve a minimum term and payment obligations. Keeping a working phone may simplify the decision, but check its calling support and security-update position.
A worn battery or full storage is not repaired by a new SIM. Conversely, buying a more expensive phone does not guarantee reception inside a difficult building. Separate device faults from service limitations.
02 / Decisions
Prepaid
Paying in advance can mean usage from credit or an allowance for a defined period. A pack may renew automatically. Check unused allowance, expiry, payment failure and inactivity conditions before treating it as an occasional-use solution.
If the number is important for account recovery, keep it active under the provider’s rules. Receiving a message occasionally should not be assumed to satisfy an activity requirement.
03 / Decisions
A phone package
Read device payments, airtime, insurance and trade-in terms as distinct components. Check what remains if the line is cancelled or moved. An upgrade entitlement can involve a return and condition assessment.
Keep your own copies of the documents. The provider’s current sales page may change and may not describe the specific arrangement already agreed.
