Frequently Asked Questions
Can I keep my number?
Yes—just request a PAC code and give it to your new provider. The switch usually happens within a day.
Will prices go up with inflation?
Many plans include annual inflation-linked increases (e.g. RPI + 3.9%). If your provider increases above inflation, Ofcom rules allow you to leave without penalty.
What happens if I use more data than allowed?
You might be charged extra or see reduced speeds. Some providers offer data limits or alerts to help you avoid overuse.
Is my phone compatible?
As long as your phone is unlocked, it will work with any UK SIM. To unlock, request a code from your current provider—it’s usually free.
Can I switch before my contract ends?
You can—but you may need to pay an early exit fee. If you wait until the contract ends, most switches are penalty-free.
Are unlimited plans really unlimited?
Yes. Most offer full data with reasonable “fair use” policies. For example, they may slow speeds after 600–1 000 GB, but that’s far more than typical use.
