FAQ

Common questions

How much does the service cost?+

This is a paid service. Our fee is [STATE YOUR FEE — e.g. a one-off £X, or £X per month]. We always show the fee clearly before you pay, and you're under no obligation until you agree to it. Full details are in our Terms & Conditions.

Do you ask for my banking information?+

No. We never ask for your bank account details or online banking login. As this is a paid service, when you choose to pay our fee it's taken securely through a card payment provider — you don't need to share any payment details just to get a comparison.

Are you affiliated with O2, Vodafone, Three, EE or Giffgaff?+

No. TeleAdvisor is an independent comparison service. We are not affiliated with, endorsed by, or operated by any mobile network, and we are not a provider's customer service line. All brand names and trademarks are the property of their respective owners and are used only to describe the deals we compare. If you need a provider's own support, please contact them directly.

Who runs TeleAdvisor?+

TeleAdvisor is an independent UK mobile and SIM-only comparison and advice service. You can reach us on 0800 820 3480.

Will I lose my number if I switch?+

No. We explain how to request your PAC (Porting Authority Code) from your current provider and how to give it to your new one. The switch itself is completed by the networks, usually with little or no downtime.

What if I'm in a contract?+

We explain whether switching now (and paying any exit fee) or waiting until your contract ends makes more sense, so you can see the trade-off and decide for yourself.
