Rolling monthly
Often provides more flexibility, but may have different prices and cancellation rules. Check the notice period.
More data isn't always more value.
A good SIM-only plan should match your actual usage, your local coverage and your comfort with the commitment.
12-month term
A defined commitment. Check the price adjustment wording, end date and early termination charges.
24-month term
May spread costs over more months. Compare the complete term cost and yearly pricing terms.
BEFORE YOU CHOOSE
Five things to verify
Real-world coverage
Check indoor and outdoor coverage at home, work and frequent travel locations with the network's own checker.
Data allowance
Use past bills or your phone's data usage settings to estimate your monthly needs.
Speed and fair use
“Unlimited” may still come with speed, hotspot or fair-use limitations.
Roaming and price rises
Check destinations, charges, out-of-bundle rates and when any price changes may apply.
A simple budget comparison
As an illustration only, a £12 monthly plan over 12 months starts at £144 before extra charges or price changes. A £15 monthly plan over the same term starts at £180. Neither is necessarily better without comparing data allowances and service conditions.
