How to Switch from Three to SMARTY

1

Get your PAC code from Three

Text PAC to 65075 from your Three phone. You'll receive your PAC code by text within a minute.

You can also call Three on 333 (or 0333 338 1001 from another phone).

2

Give your PAC to SMARTY

Sign up for a SMARTY plan and give them your PAC code. You can usually do this online at smarty.co.uk/your-account, in-store, or by phone.

3

Wait 1 working day

Your number will transfer from Three to SMARTY within 1 working day. You'll get a text when the switch is complete. Your old Three contract is automatically cancelled.

Things to Check Before Switching

  • Contract status — Check if you're still in contract with Three. You can switch at any time, but you may need to pay an early termination fee if your minimum term hasn't ended.
  • Outstanding balance — If you're paying off a handset, you'll need to settle any remaining balance with Three.
  • Phone compatibility — Make sure your phone is unlocked and compatible with SMARTY's network. Most phones sold since 2015 are unlocked.
  • Coverage — Check SMARTY coverage in your area before you switch.

Same Network Coverage

Three and SMARTY both use the Three network, so you'll get the same coverage after switching. No need to worry about signal changes.
