Switching Made Simple: How to Move to 1pMobile and Keep Your Number (2026 Guide)

Switching mobile providers used to feel like a chore. People worried about losing their number, being cut off for days, or getting hit with surprise fees. In 2026, it's a lot simpler.

Ofcom's streamlined switching rules and the widespread use of text-to-switch mean you can move to a better-value provider without the drama. If you're out of contract (or paying more than you should), switching can be one of the quickest ways to cut your monthly costs.

This guide walks you through the process step by step � from checking your contract end date to moving your number across to 1pMobile.

Before you start: what you'll need

Your current mobile number
Your account details with your current provider (usually your name, address, and account number)
A payment method for your new 1pMobile plan (card or PayPal)
A little timing: most number transfers happen quickly, but it's still best not to leave it until the day before you travel

Step 1: Check if you're in contract (and when it ends)

First question: are you tied into a contract?

If you're on a 30-day SIM-only plan, you're usually free to leave with a month's notice (or sometimes immediately, depending on the provider). If you're on a handset contract, you may have an early termination fee if you leave before the minimum term ends.

Here are the easiest ways to check your contract end date in 2026:

Look at your latest bill: many providers show your minimum term end date on the PDF bill or in the app.
Check your provider's app: go to Plan, Contract, or My account.
Ask via live chat: request "my contract end date and any early termination charges."
Call customer support: if you prefer speaking to someone, ask for the same details.

If you're already out of contract, you're in the best position: you can switch without penalty and stop overpaying for a legacy deal.

Step 2: Decide whether you want to keep your number

Most people do � and you absolutely can.

Keeping your number is called porting. It's standard in the UK and designed to be straightforward. Your bank, WhatsApp, and two-factor codes don't need to change because your number stays the same.

If you don't want to keep your number (for example, you're setting up a second phone or a tracker SIM), you can simply start fresh with a new number.

Step 3: Request your PAC code (text-to-switch)

To move your number from your current provider to 1pMobile, you'll usually need a PAC code (Porting Authorisation Code).

In 2026, the simplest method is still text-to-switch:

Text "PAC" to 65075 from the SIM you're switching away from.
You'll receive a text back with:
- Your PAC code
- The date it expires
- Any early termination charges (if you're in contract)

That's it. No awkward phone calls. No "retentions" script. Just the info you need.

What if you want to cancel your old number instead?

If you're cancelling your service and don't want to keep the number, text "STAC" to 75075. (That's the standard cancellation code process.)

For most people switching to 1pMobile and keeping their number, PAC to 65075 is the one you want.

Step 4: Order your 1pMobile SIM (or eSIM)

Once you've got your PAC, you're ready to join 1pMobile.

You can choose:

Physical SIM: delivered to you, then you pop it into your phone.
eSIM (if your phone supports it): ideal if you want to get going quickly.

Pick the option that fits your device and how fast you want to switch.

Step 5: Activate your 1pMobile service

When your 1pMobile SIM arrives (or your eSIM is ready), activate it.

At this stage, you'll typically:

Confirm your personal details
Choose your plan (PAYG or a 30-day Boost)
Set up payment (including auto top-up if you want it)

If you're switching to save money, it's worth taking 60 seconds to compare what you're paying now versus what you actually use. Many people stay on old plans out of habit � and that's where the overpaying creeps in.

Step 6: Transfer (port) your number to 1pMobile

This is the key step: moving your number across.

When prompted during sign-up or in your account, enter:

Your PAC code
Your current mobile number
Any requested account details (to match your old provider)

Once submitted, your number transfer is scheduled.

How long does it take?

In most cases, number ports happen quickly. You may notice a short period where calls or texts briefly pause while the switch completes.

Tip: if you rely on your phone for work or important calls, do the transfer on a weekday and avoid late-night switching.

Step 7: Check everything works (calls, texts, data)

After your number has moved, do a quick checklist:

Make a call
Send a text
Turn mobile data on and load a webpage
If you use Wi-Fi calling, check it's enabled in your phone settings

If anything looks off, it's usually a simple settings refresh (like restarting your phone) � and it's better to catch it right away.

Common switching worries (and the real answers)

"I'll lose my number."

You won't, as long as you use a PAC and complete the port. Your number is designed to be portable.

"Switching takes ages."

It used to. In 2026, text-to-switch and clearer switching processes mean it's usually fast and predictable.

"I'll be without service for days."

In most cases, you won't. There can be a short handover window, but long outages are not the norm.

"I'll get charged twice."

There can be a short overlap depending on billing dates, but you can reduce this by:

Checking your billing cycle
Switching near the end of your current billing period
Confirming any early termination fees before you commit

"My phone might not work."

If your phone is unlocked, you're good. If it's locked to a network, you'll need to request an unlock from your current provider.

Myth: "It's risky to move providers."Reality: the UK switching process is built around keeping your number and minimising disruption.
Myth: "I should just stay put � it's easier."Reality: once you've done it once, you'll wonder why you waited.
