Complete Guide to Giffgaff Number Porting and Balance Refund (2026 Latest)

📌 Who is this guide for? This guide is designed for users who want to port their existing UK Giffgaff mobile number to VOXI, CTExcel UK, or another UK network provider, and request a refund of their remaining paid account credit. 💡 This guide strictly covers practical operational steps and contains no affiliate links or sponsored promotions.

1. Recommended Order of Operations

Please follow these steps in sequential order. Do not skip or reorder steps:

Confirm your phone supports Wi-Fi Calling.
Request a PAC code from Giffgaff.
Order and activate your new UK SIM card or eSIM.
Port your Giffgaff number to the new provider.
Verify that the number transfer is fully complete.
Contact Giffgaff to request a refund of your remaining paid credit.

⚠️ Important Warning

Do NOT close or cancel your Giffgaff account before the number transfer is complete, and do NOT request a refund in advance. Doing so may invalidate your PAC code, lead to loss of your mobile number, or result in a rejected refund request.

2. Obtaining Your Giffgaff PAC Code

A PAC (Porting Authorisation Code) is required to transfer a UK mobile number. It is valid for 30 days.

Method 1: Via SMS (Recommended)

Using your active Giffgaff SIM card, text:

PAC

to:

65075

Once you receive a reply, make sure to save:

Your PAC Code (3 letters followed by 6 digits)
Your current Giffgaff mobile number
PAC expiration date

Method 2: Via the Giffgaff Website

If you cannot send SMS messages:

Log in to your Giffgaff account online.
Go to Account Settings.
Locate the Get a PAC code / Leaving giffgaff section.
Follow the on-screen instructions to request your PAC code.

💡 Note: If your line is completely inactive and you cannot request a PAC code via SMS or website, contact Giffgaff customer support directly.

3. Test Wi-Fi Calling Before Porting

If you are currently outside the UK (e.g., mainland China, Hong Kong, Macao, or other roaming destinations), confirm that Wi-Fi Calling is functional on your device with the target carrier.

Wi-Fi Calling is essential for international roaming:

Activating a new number and receiving OTP verification codes
Receiving SMS and making/receiving calls without cellular roaming signal
Maintaining UK service at zero or minimal cost

Pre-checks to complete:

Phone hardware and OS support Wi-Fi Calling.
The new carrier supports Wi-Fi Calling on your specific device model.
Wi-Fi Calling toggle is enabled in system settings.
Your Wi-Fi network does not block carrier IPSec / Wi-Fi Calling ports.
Device EID is not restricted by carrier policies for eSIMs.

Option 1: Porting to VOXI

4. Ordering and Activating VOXI

Select a SIM-only plan on the official VOXI website.
Choose physical SIM or eSIM based on your device.
Complete registration and payment.

For eSIM orders, locate the QR code / installation parameters in your email.
Scan the QR code to install the VOXI eSIM.
Enable the VOXI line in device settings.
Enable Wi-Fi Calling.
Log in to your VOXI account online.
Complete SMS verification to finalize activation.

📌 Important Note

Do NOT submit a porting request until your new VOXI line is fully activated and receiving SMS verification codes.
