Thinking of leaving?

Let's make your next step simple

We're genuinely sorry to see you go. Whether you'd like us to put things right or need to move on quickly, we'll guide you through every option.

No scripts - just people who want to help you stay connected on your terms.

Before you decide

Most departures start with something we can fix - from billing tweaks to an unexpected coverage dip. Give us one conversation to put things right.

  • Coverage boost: We can run live network diagnostics and offer signal boosters where helpful.
  • Plan review: We'll audit recent charges and match you to a tariff that fits what you actually use.
  • No-pressure cooling off: Pause a port or undo a code request while we work together on a fix.
How we follow up
  1. A specialist calls you back within 2 working hours.
  2. We agree an action plan and keep you updated.
  3. Stay or go, we confirm everything in writing.

Already made up your mind? Scroll on - we'll get your PAC or STAC organised.

Choose the route that fits

Keep your number while you switch, or close your account completely. Both options are regulated and quick.

Moving and taking your number (PAC)

Use a PAC if you want your existing number to follow you to another UK mobile network.

Text PAC to 65075
  • Code arrives by SMS within 60 seconds.
  • Valid for 30 days - share it with your new provider.
  • Requests must be made from the UK on the number you're moving.
Next steps: Give the code to your new network. They'll schedule the transfer and we'll automatically close your TISA account on completion.

Cancelling without the number (STAC)

Use a STAC when you're ending service entirely and don't need to keep your number active anywhere else.

Text STAC to 75075
  • Codes are free and valid for 30 days.
  • Your number will be disconnected permanently.
  • Share the code with your new provider or call us to set a closure date.
Important: After the STAC completes, we send a final bill (or credit). Make sure any outstanding device payments are settled.

What happens after you request a code

Right away

We text the code and account info

You'll also see your remaining contract term, credits, and early termination fees (if any).

Within 1 day

Schedule the move

Give the code to your new provider or confirm a cancellation date with us. Ports submitted before 4pm usually complete next business day.

After completion

Account closes automatically

We send final billing within 7 days. Any credit is refunded to your original payment method.

Need to pause or cancel the request? Contact us before the port date - we can stop or reschedule up to 4pm the working day prior.

Have these details handy

  • The number you're moving or cancelling.
  • Account holder name and last 4 digits of the payment method for verification.

Frequently asked questions

Answers to the most common queries about leaving TISA.

We'll include any remaining device payments or contract fees in the SMS that includes your PAC or STAC. You only pay for the services you've already used plus any agreed device balance.

Yes. Call us before the scheduled transfer date and we'll cancel the code, reactivate your number if needed, and review any improvements we can make.

Texting from each line is the fastest approach, but we can produce multiple PAC or STAC codes for you in one call-especially useful for business or family accounts.

Once the account closes we generate a final statement within 7 days. If you're owed money, we refund the card or bank account on file automatically; if there's a balance due, we'll email instructions.
