Switch from Vodafone to Three

Keep your phone number when you switch from Vodafone to Three. Here's how in 3 simple steps.

Updated July 2026

Switching from Vodafone to Three moves you to a network that is well known for generous unlimited data plans and inclusive international roaming in over 70 destinations. Three operates its own independent infrastructure and has been expanding its 5G coverage rapidly across the UK. The PAC code process makes the switch straightforward, with your number moving across in one working day.

Important Warning

Do NOT cancel your contract manually. If you cancel before transferring your number, you will lose it permanently. Your old contract will automatically cancel once the transfer completes.

Pre-Switch Checklist

  • Back up your data: Contacts, voicemails, and saved messages won't transfer.
  • Unlock your phone: Ensure it's not locked to your old network if you plan to keep using it.
  • Check Early Termination Fees: Text INFO to 85075 to see if you'll incur charges for leaving early.

How to Switch from Vodafone to Three

1

Get your PAC code from Vodafone

Text PAC to 65075 from your Vodafone handset to receive your PAC code instantly via SMS. You can also call 191 from your Vodafone phone, dial 0333 304 0191 from another phone, or visit vodafone.co.uk and request the code through your online account. The PAC remains valid for 30 days.

2

Give your PAC to Three

Pick a plan at three.co.uk, head to a Three store, or call Three on 0333 338 1001. When placing your order, select the option to transfer your existing number and enter your Vodafone PAC code. Three will begin the porting process once your new SIM or eSIM is set up.

3

Wait 1 working day

Your number will transfer from Vodafone to Three within 1 working day. You will receive a text on your new Three SIM confirming that the port is complete. Your Vodafone contract will be automatically terminated at the moment the number moves across, and Vodafone will send a final bill for any remaining charges.

Transfer Cut-off Times: Submitting your PAC code before 5:30 PM usually means your number will transfer the next working day. Submitting it after 5:30 PM or on weekends/bank holidays will add an extra working day to the process.

Final Bill: You'll receive a final bill from Vodafone shortly after the transfer is complete. This covers your usage up to the date of the switch.

Things to Check Before Switching

Check if you are still in your Vodafone minimum contract period, as you will be charged an early termination fee for leaving early. If you have a Vodafone Together bundle with broadband, switching your mobile may affect your bundle discount. Make sure your phone is unlocked for use on Three.

Different Network Coverage

Vodafone and Three run entirely separate networks, and coverage differences can be significant, particularly in rural and suburban areas. Three tends to offer strong speeds in city centres but may have patchier coverage in remote locations. Use Three's coverage checker at three.co.uk/coverage to verify signal quality in your area.
