Switching from Lycamobile to Sky Mobile? It's a straightforward process to keep your existing phone number.

Sky Mobile

Step 1: Obtain a PAC Code from Lycamobile

The first step is to contact Lycamobile to obtain your Porting Authorisation Code (PAC Code).

You can get a PAC Code from Lycamobile by calling 322 on your Lycamobile handset. Alternatively, dial 020 7132 0322 from any other phone.

You can request a PAC Code over the phone at any time during Lycamobile's opening hours:

Monday - Friday8.00am - 8.00pm
Saturday9.00am - 6.00pm
Sunday9.00am - 6.00pm

Here are some key things to know:

  • A PAC Code is 9 digits long and follows the format ABC 123 456.
  • Lycamobile must provide a PAC code within 2 hours of your request. If they don't, they must provide a valid reason for why the PAC Code can't be issued. Your right to a PAC code is enshrined within clause 18 of Ofcom's "General Conditions of Entitlement".
  • Your PAC Code is valid for 30 days. If you don't use it during this time, the PAC code will expire and you'll need to request a new one.
  • You shouldn't close your account at Lycamobile: it'll end automatically when your phone number is transferred to Sky Mobile.

Step 2: Order your new phone or SIM card from Sky Mobile's website

You should now order your new phone or SIM card using the Sky Mobile website. Please select the type of tariff you're intending to move to:

Sky Mobile will assign you with a temporary phone number during the transition process. This will allow you to test out the service before you finally transfer your phone number to Sky Mobile.

Step 3: Give the PAC Code to Sky Mobile

Once your new phone or SIM card arrives from Sky Mobile, switch it on and make sure everything's working properly. If you need to return/replace the new phone or SIM card, please do this before the phone number transfer.

Once you're happy to continue with the phone number transfer, contact Sky Mobile and provide them with your PAC Code.

Your PAC Code should be entered on Sky Mobile's online form. Alternatively, you can give the PAC Code to Sky Mobile by calling 03300 412 524 on your Sky Mobile handset. You can also call 03300 412 524 from any other phone.

Providing your PAC Code to Sky Mobile
The PAC Code should be submitted through a form on Sky Mobile's website.


  • You must provide the PAC Code to Sky Mobile within 30 days of it being issued by Lycamobile. If the PAC Code has already expired, you'll need to return to step 1 and request a new PAC Code from Lycamobile.
  • Lycamobile Pay As You Go customers: Try to use up your remaining credit as it can't be transferred to Sky Mobile.

Step 4: Phone Number Transferred (Next Working Day)

As long as you've submitted your PAC Code to Sky Mobile before 5.00pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding English bank holidays). After 5.00pm, you'll need to wait one extra working day for your number to be transferred.

On the day of the transfer, you'll momentarily lose coverage on both mobile networks. When this happens, restart your handset on Sky Mobile. You should find that the Sky Mobile phone or SIM card will now associated with your original phone number.

  • If you see an error message (e.g. "SIM card registration failed"), this means it's time to restart your phone.
  • Once the phone number has been transferred to Sky Mobile, your account on Lycamobile will automatically be closed. You'll receive a final bill from Lycamobile for any outstanding charges.

  • I have been struggling transferring my number from Lyca to Sky mobile. I’ve tried several ways. It has been a month today.
    My number is Lyca. I’ve made a contract with sky. Then I got PAC code from Lyca. When I transferred to Sky mobile, I couldn’t. Then I called Sky mobile but Sky mobile couldn’t help me because Sky mobile has no agreement with Lyca.
    Is that possible? I hope someone able to help me out.

    • Hi Yin,
      Sorry to hear about the problems you’ve encountered transferring a phone number from Lycamobile to Sky. I’m not aware of any reasons why this shouldn’t be possible: Sky should be able to accept a PAC Code from any network. I’d probably recommend making a complaint in writing to Sky, so you can escalate the issue or at least get the restriction in writing.
      Best wishes,

      • This issue has been ongoing since Sky started. They claim not to “have an agreement with Lyca” which is totally against the spirit (and probably legality) of OFCOM regulations. Seems Sky can do what they want, and totally flout the number portability arrangements applying to ALL U.K. operators ☹️
