Switching and PAC codes

You keep your number, free: text PAC to 65075 for your transfer code (PAC), and the move is done generally within one working day.

Put the code in the Simp app and pick the day. You're never without a phone while your number moves.

Try Simp as a second line first.

Install your Simp eSIM next to the SIM you already have. It works straight away on a new Simp number, so you can test it where you live and work. Move your number across when you're happy.

Both work at once. Move your number when you're ready.
How it works

Three steps.

  1. Step 1Get your codeText PAC to 65075 from the number you want to keep. Your current provider texts you the code, and they have to send it.If your Simp eSIM is already in, send it from your old line.
  2. Step 2Give it to usIn the Simp app, go to Your numbers, tap Manage on your main number card, then Keep your number. Enter the code.
  3. Step 3Pick the dayChoose any working day up to 30 days ahead. Until then you keep using both lines.
The day itself

When your number moves.

Code in before 5pm on a working day, and the earliest move is the next working day. After 5pm, it's the day after that. Weekends and UK bank holidays don't count.

Example
  • There's no set time on the day. Give it until the end of the day.
  • Once it's done it can take a few hours to settle across the network.
  • Once you submit, the date can't be changed or cancelled. If a move fails, you just submit again.
New number

Want a new number instead?

You can leave your old provider with a STAC code instead of a PAC. When the app asks if you want to keep your number, enter it there.

Not switching at all?

Keep your network and add an AI number.

Simp AI works next to whatever plan you already have, with no eSIM and nothing to move.

Leaving

And if you ever leave, your number comes with you.

Your number is yours. Take it with you to your next provider.

Your AI number can't be moved to another provider.
  1. Step 1Cancel your plan in the Simp app and request your transfer code (PAC) there.
  2. Step 2You can also text PAC to 65075 from your Simp phone without cancelling: your plan then ends when your number moves to your new provider, and any billing period that starts before then is still due.
  3. Step 3Give the code to your new provider.

Questions about switching to Simp Mobile.

How long is a PAC valid for?

30 days. If it runs out, ask your old provider for a new one.

Will I lose signal while it moves?

You keep both lines working until the move, and your Simp eSIM works from the moment you install it.

Can I change the date after I've submitted?

No. Once it's in, it's fixed. If the move fails, submit it again.

It's been a day and my number hasn't moved.

Sometimes the old provider releases the number late. Check the Support page or ask in the app.

The wrong number shows on my iPhone after the move.

Your phone can keep showing the temporary number for a while after the move. A restart usually fixes it, and the support article has the rest.

Do I get an AI number either way?

Yes. Your AI number is separate from your mobile number, so you have both.

Bring your number. Keep your plans.

Keep your number, pick the day, and never go without a line.
