Quick answers to common questions about SIM-only deals.
What is a SIM-only deal?
A SIM-only plan gives you mobile data, calls and texts without a new handset. It can be a flexible 30-day plan or a longer fixed term.
Can I keep my existing number?
Usually, yes. Your current provider can give you a PAC, which you give to your new provider to move the number. Check the provider’s instructions before ordering.
What’s the difference between a 30-day and 12-month plan?
A 30-day plan is more flexible. A 12-month plan normally commits you for longer, so compare the minimum contract cost as well as the monthly price.
What is an eSIM?
An eSIM is a digital SIM built into a compatible phone. Availability and setup depend on the provider and your handset.
Which UK network is best for roaming?
Roaming rules differ by provider and plan. Check the included destinations, data limits and any fair-use terms before travelling.
