How to Switch from Three to Vodafone

Thinking of switching from Three to Vodafone? Here is what you need to know, especially about differences in 5G coverage and speeds, before you make the move.

Before you switch

Check your contract end date with Three, as leaving early can mean paying an exit fee. Review your account for any bundled services, such as voicemail or network-specific features, which may not transfer to Vodafone. Your email address is not affected by the switch, but confirm if you have any services tied to your Three account that could be lost when you cancel.

How to switch, step by step

Mobile: To keep your number, text PAC to 65075 from your Three phone. You will get a PAC code valid for 30 days. Give this code to Vodafone when you sign up. Your number will port over within one working day. If you want a new number, text STAC to 75075 instead and provide the code to Vodafone.
Broadband: If you are switching broadband and both providers use Openreach, Vodafone's One Touch Switch will handle the transfer. Choose your Vodafone plan and installation date. Your equipment arrives three days before installation, and the switch completes on the agreed day. An engineer visit may be required, depending on your address and service type.
Energy: For energy, switching is supplier-led. Pick your new supplier, who will handle the switch from your current provider. The process usually takes about five working days under the Energy Switch Guarantee.

What to watch out for

Number porting from Three to Vodafone can be delayed if the PAC code is not provided promptly or if account details do not match. Double-check your information before starting.
Broadband installation dates may be pushed back, especially if an engineer visit is needed or if there are local infrastructure issues. Confirm your installation date with Vodafone.
Some features or services tied to your Three account, such as specific voicemail settings or bundled add-ons, may not transfer automatically. Set these up again with Vodafone after switching.
