Different iPhone models use different sized SIM cards. This article shows which SIM you will need for your iDevice. It also shows you how to insert and remove the SIM
If you need a new SIM, you can order one from theOrder page. If you are an existing giffgaff members switching to a different sized SIM, you can then use SIM Swap to transfer your number and credit to this new SIM.
Phones that work on O2 or that have been purchased from giffgaff or the Apple Store unlocked will work on giffgaff without unlocking. Phones from other networks will generally require unlocking before being used with a giffgaff SIM.
If this does not work straight away, you can connect your iPhone using the giffgaff SIM card to iTunes to setup and sync your phone.
giffgaff is unable to unlock an iPhone which has been purchased from another supplier but you can contact the seller to ask to unlock it. Please note that this may not be possible or can be chargeable depending on the agreement you have with the seller.
If your iPhone is running iOS 7.1.1 or later, you will receive a notification telling you that the giffgaff carrier settings are available. Simply follow the on-screen instructions to install the carrier profile.
If you haven't received the notification, you can force your iPhone to check for the update by using a Wi-Fi or a 3G/4G Internet connection and going to:
Settings > General > About
Wait a few seconds and the iPhone should prompt that an update is available. You can also find this update by connecting your iPhone to itunes.
If your iPhone is running an older version of iOS, you will have to update it to the latest versionto install the carrier settings. When you upgrade iOS to a newer version, the carrier profile is reset to the latest version available during the update.
Change your carrier profile manually
If your iDevice is running an older version of iOS, it is possible to modify the internet settings by downloading giffgaff's carrier profile. You'll need to access this link using the Safari browser on an Iphone; please note it won't be displayed properly on any other device.
This will replace your current profile with giffgaff's Internet settings, including the parameters which can't be modified manually (e.g. proxy settings). MMS settings must be modified manually, see below.
Manual update of MMS Settings
You can view the APN settings on your iOS device in Settings > Cellular > Cellular Data Network.
sorry we don't have Visual voicemail, however there are alternatives such as Hullomail
If your iphone is using IOS 7.1.1 or later, the red blob indicates new voicemail and you can tap the voicemail icon and access your voicemail.
If you're using iOS 7.1.0 or earlier, voicemail can be confusing on iPhone. You get the red blob on your Voicemail icon, but you can't use the Voicemail button to pick up your messages, you have to dial 443 instead. Changing to text alerts alleviates this:
Press * to get to the main menu
Press 4 for Mailbox Settings
Press 1 for Notification options
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 set a custom tone so that voicemails sound different to texts (iOS 5 & higher only).
After porting your number to giffgaff, iPhones often have a problem where your original giffgaff number appears rather than your own when you send iMessages to some people. There is an easy fix for this:
Go to Settings
Go to Messages
Switch iMessage OFF
Once it's switched off, turn it back ON again.
Wait for it to finish activating
Go to Settings
Go to Phone
Check that the number under "My Number" is correct, if not, change it
Reboot your phone (switch the phone off and then on again)
Your iMessages should now display the correct number.
