General Chips describe how well-sourced a number is, not how good the network is. How we verify explains what each means.
The same everywhere
Three shortcodes work on every network
| Text this | To | And you get |
|---|---|---|
| PAC | 65075 | A code to switch and keep your number |
| STAC | 75075 | A code to leave without keeping it |
| INFO | 85075 | Whether you are in contract, and what leaving would cost |
Sky Mobile is the exception on format: it asks you to add your date of birth, for example PAC 17041987. Details on the Sky Mobile page. Verified
Start with INFO. It tells you the price of leaving before you talk to anyone, which is worth more than any negotiating script. Ofcom requires a residential PAC or STAC to arrive within one minute. Verified
Where they differ
Notice, exit fees and handset debt
| Network | Notice | Leaving early | Handset |
|---|---|---|---|
| O2 | 30 days | SIM Only: the rest of your term, minus 4%. | On O2 Refresh the handset is a separate debt. |
| EE | 30 days (or none, if you switch with a code) | EE calls it the Remaining Contract Charge. | EE rolls the handset into the same bill. |
| Vodafone | 30 days (or none, if you switch with a code) | Vodafone publishes the formula. | You have 30 days to pay for the handset. |
| Three | None | Airtime: the rest of your monthly charges. | Your device plan does not go away. |
| giffgaff | None stated | 18-month contracts: half the plan price for each full month left. | A giffgaff phone loan is a Klarna loan, and you keep paying it. |
| Tesco Mobile | Next billing date | Your monthly charge for the months left, less about 20%. | Leave before month 24 and the phone balance is due in full. |
| Sky Mobile | 31 days | The monthly charge, less Sky’s savings, for the time left. | Your phone repayments carry on after you cancel. |
Three things stand out. Three asks for no notice at all: mobile leaving runs on the code, and Three applies notice only to its broadband. EE is the only one that folds handset debt into the exit charge; everywhere else the phone is a separate debt, and at O2 and Tesco Mobile leaving before month 24 makes the balance due at once. And giffgaff publishes no customer service phone number at all, only a shortcode for PAC and STAC requests.
