How to giffgaff iPhones (all iOS versions)

It's easy to use your iPhone 3, 4 or 5 on giffgaff! This guide contains everything you need to know, just select the section that matches your need:



How do I get a micro SIM or a nano SIM?

 Back to top



The iPhone 4 and 4S both require a micro SIM, these are slightly smaller than the normal SIM you might be used to. All new giffgaff SIM cards are 'hybrid SIMs' which contain both normal and micro SIM. 


The iPhone 5 requires a new SIM card called a nano SIM, this is smaller than a micro SIM again. If you need a nano SIM, you can order one from the Order page.  If you are an existing giffgaff members switching to the nano SIM, you can then use SIM Swap to transfer your number and credit to this new SIM.




Do I need to unlock my phone?

 Back to top



Phones that work on O2 or that have been purchased from the Apple Store unlocked will work on giffgaff without unlocking. Phones from other networks will generally require unlocking unless already done.

Change your carrier profile


It's possible to reset the profile of your iPhone or iPad by clicking ths link to download giffgaff's carrier profile:


To use it:

  • Connect to a Wi-Fi network
  • Come to this page and click
  • Download and install the carrier profile
  • Reset your 3G connection

This will replace your current profile with giffgaff's Internet settings, including the parameters which can't be modified manually (e.g. proxy settings).




Manual update


Some of the settings (e.g. proxies) are not available to phone users. For this reason, we invite you to use this method only when you are unable to use any of the two methods above.


  1. Go to Settings
  2. Go to Mobile (or Cellular)
  3. Go to Mobile (or Cellular) Data
  4. Under Mobile (or Cellular) Data Network, enter the Internet settings
  5. Under MMS, enter the MMS settings available in the next section
  6. Switch your data off and on


Download the leaflet here: giffgaffer's guide to iPhone / iOS, it's a really great brochure sized visual guide to setting up your iPhone. Thanks to Essexmate for his great work on this.


The settings information given can be used by all iPhones running iOS4 or later except the first iPhone and including the iPhone 5.

A) Setting up your voicemail, see this article about voicemail


B) Visual voicemail - sorry we don't have Visual Voicemail, however there are alternatives such as Hullomail


C) If you would prefer to get notification by text, see this guide below:


Voicemail can be confusing on iPhone if you don't change the settings. You get a red blob on your Voicemail icon, but you can't use the Voicemail button to pick up your messages, you have to dial 443.


The good news is, it's easy to change to text notifications and avoid this:


1.) Call 443
2.) Press * to get to the main menu

3.) Press 4 for Mailbox Settings

4.) Press 1 for Notification options

5.) Press 1 to enable text notification 


Now, when you get a voicemail, instead of the red blob you'll get a text like this, and you can just click "Call" to pick it up:





What's even cleverer is that if you get more than one voicemail, this text will update itself to say "2 new messages", "3 new messages", etc. You'll never see a big long list of texts here - just one, with the latest count of voicemails. Very neat.


Extra tip - if you add 443 to your Contacts, you can even set a custom tone so that voicemails sound different to texts (iOS 5 & higher only).

Many iPhones on giffgaff have a problem where when you send messages to some people, your old number appears rather than your new one. There is an easy fix for this.


 1) Go to Settings

 2) Go to Messages

 3) Switch iMessage OFF

 4) Once it's switched off, turn it back ON again.

 5) Wait for it to finish activating iMessage

 6) Once it's done, reboot your phone.


Your messages should now display the right number.
