PAC Codes for VOXI, Sky Mobile, SMARTY, Talkmobile and Lyca

To get a PAC code from VOXI, Sky Mobile, SMARTY, Talkmobile or Lycamobile, text PAC to 65075 from the number you want to keep. Sky and SMARTY want your date of birth in the same text, and Talkmobile asks for the last two digits of your account PIN. The code arrives within a minute, costs nothing, and lasts 30 days. Give it to your new network and your number moves across, normally the next working day.

These five networks have no shops and mostly no phone lines, which is why their customers end up searching for the process. The text route is the same Ofcom rule that applies to EE or O2, but each network adds its own wrinkle: a date of birth, a PIN, a multi-SIM rule, or a refund window. This page collects them in one place.

VOXI PAC code

Send the PAC text and VOXI replies within a minute. There is also a dedicated PAC line, 08080 057 451, and a “Leave VOXI” section in your online account. VOXI runs on Vodafone’s network, but moving to Vodafone itself still needs the PAC.

• Timing: give the code to your new network before 5pm Monday to Friday and the number moves the next weekday. After 5pm it can take two.
• Left without a PAC? You have a month. One number on the account: start a chat. Several: call the PAC line. After that VOXI cannot issue one and the number is gone.
• Refunds: within 60 days of leaving, ask on chat for any remaining credit and any completely unused bundles.
• Just stopping the plan is not the same. VOXI plans are monthly subscriptions you can stop in the app, but the line then sits dormant and is disconnected after six to nine months. If you want the number elsewhere, use the PAC.

Sky Mobile PAC code

Sky wants your date of birth in the text, eight digits: PAC 17041987 to 65075, for someone born on 17 April 1987. The reply includes the code, your contract end date and any early termination charge. Sky Mobile uses O2’s network.

• More than one Sky SIM: the text route is off. Sign in at sky.com/leavesky or call 03300 412 524. Sky texts a security code to confirm you are the account holder, which is where the forum complaints start: if that code never arrives, call rather than retrying online.
• Timing: services cancel one to two working days after you hand the code over.
• Already cancelled? You can still request a PAC up to 31 days after cancelling a SIM plan, by phone. Unused, the number is lost.
• Phone loan: a Sky device credit agreement carries on. Pay the balance or keep paying monthly.
• Got a PAC you did not ask for? Call 0333 759 5127 straight away; someone may be trying to take the number.
• Two Sky SIMs: Sky forum regulars say a PAC cannot move a number from one Sky SIM to another. The workaround is to port it to another network and back.

SMARTY PAC code

SMARTY also asks for a date of birth, but six digits: PAC 241285 to 65075. Or sign in, open Menu, then Manage plan, then Leave SMARTY. The code is texted, emailed and shown at the top of your dashboard. SMARTY runs on Three.

• Turn off auto-renew first. Requesting a code does not close your account. Until another network uses it, SMARTY keeps taking payments if auto-renew is on. Once the port completes, your account closes and your dashboard shows any refund you can claim.
• Changed your mind? Turn auto-renew back on, or renew the plan if it has expired. An account left inactive for 220 days is closed automatically, with a warning email 40 days before.
• Group plans: on Everyone Unlimited, the group owner cannot leave or request a code until every member has left. On Mix & Match, the owner can leave and still manage the group.
• Timing: submit the code to the new network between 8am and 5pm on a weekday and the port completes by the end of the next working day.

Talkmobile PAC code

Talkmobile’s own instruction is to text PAC plus the last two digits of your account PIN to 65075; the reply carries the code and any early termination fee. You can also call 5888 from a Talkmobile phone or 0333 304 8064 from any other, use the orange chat button, or sign in and open the Switching section, where the code can be viewed at any time. Talkmobile is Vodafone-owned and uses its network.

• In contract? You can still get the code, but the fee applies. Out of your commitment period there is none.
• Do not just cancel. Talkmobile is blunt about it: cancel the account without a PAC and the number is terminated and cannot be recovered.
• Joining Talkmobile with your number: put the new SIM in, dial *#100# to see the temporary number, then enter it with your PAC and your old number at talkmobile.co.uk/keepmynumber. You pick the transfer date, and on the day the number moves between 1pm and midnight. The date can be changed up to two days before.

Lycamobile PAC code

The Lyca PAC code works like the others: send the PAC text and Lyca replies within a minute, free, and the code is valid for a month. If the text fails, call 322 from a Lyca number or 0207 132 0322 from any other, and customer services can issue it. Lycamobile UK now runs on EE’s network.

• Credit is lost. Lyca says to use any remaining credit before the switch, because it goes when the port completes. Bundles too.
• Leaving the number behind: text STAC to 75075 instead, and the number is cancelled rather than moved.

What is the same on all five

These are Ofcom rules, not network policy, so no small network can make them harder:

• The PAC is free and must arrive within a minute of the text.
• It is valid for 30 days. Let it expire and nothing happens; your plan carries on.
• Requesting it does not cancel anything. Only the new network using it ends your old service.
• The new network must complete the switch within one working day of accepting the code.
• You are not charged for a notice period that runs past the switch date.
• Text INFO to 85075 first to see any leaving charges or your credit balance without starting anything. Sky wants the birth date on this text too.

How the code itself works, and what to do when a port stalls, is in the main PAC code guide. If you are leaving and do not want the number, the STAC code is the other route.

When the text does not work

• Nothing comes back: check the format. Sky needs DDMMYYYY, SMARTY DDMMYY, Talkmobile two PIN digits, and all of them want the text sent from the number you are moving.
• Several numbers on one account: every one of these networks pushes multi-SIM accounts to the website or a phone call. The text route handles only the number it is sent from, and on some accounts fails silently.
• “Invalid PAC” at the new network: type it in by hand with no spaces. A PAC is three letters then six digits. If it still fails, ask the old network to re-issue it; a second request cancels the first.
• Calls out but none in after the port: the move is half done. The new network owns the problem; chase them, not the old one.

Common questions

Do I need a PAC to move between two networks on the same host?

Yes. VOXI to Vodafone, SMARTY to Three or Sky to O2 is still a change of provider, and the number only moves with a PAC. (Not sure which network yours uses? See which network every provider uses.) The shared mast network makes no difference.

Does requesting a PAC cancel my plan?

No. The plan ends when your new network uses the code. SMARTY is the one to watch: switch off auto-renew yourself, or the monthly payment keeps going while the code sits unused.

Will I get my credit back?

Depends on the network. VOXI refunds credit and unused bundles if you ask within 60 days. SMARTY shows a refund entitlement on your closed account. Lyca does not refund credit, so spend it first.

I cancelled without getting a PAC. Is the number gone?

Not yet, if you move quickly. VOXI gives you a month after leaving and Sky 31 days; both need you to chat or call rather than text. SMARTY emails the code with its closure warning. After the window, the number goes back into the pool, which matters most if it was a premium mobile number you paid for.

The short version

Text PAC to 65075, adding your birth date on Sky or SMARTY and two PIN digits on Talkmobile. Several SIMs: use the website or call. Give the code to the new network, keep the old SIM in until the number moves, and claim any credit refund inside the window.
