Step 1: Check for giffgaff Outage

Before changing any settings, check whether giffgaff is experiencing a network outage in your area. An outage is the most common reason for sudden data loss.

Check giffgaff status: https://community.giffgaff.com

If there is a confirmed outage, no settings changes will help — wait for the network to recover and check the status page for updates.

Step 2: Quick Fixes

  1. Toggle Aeroplane Mode on for 30 seconds, then off. This forces your phone to reregister on giffgaff's network.
  2. Restart your phone fully — a restart clears network caches and reapplies APN settings.
  3. Check Mobile Data is enabled: Settings › Mobile Data (iPhone) or Settings › Connections › Mobile Data (Android).
  4. Check Data Allowance: if you've used your monthly data allowance, mobile internet will stop. Check in the giffgaff app.
  5. Remove and reinsert the SIM card — a dirty or unseated SIM can cause data to drop intermittently.

Step 3: Verify giffgaff APN Settings

Incorrect APN settings are a very common cause of mobile data failure, especially after a factory reset or SIM change. Verify the following values are set exactly:

APN: giffgaff.com
  1. Open Settings › Connections › Mobile Networks › Access Point Names (Android) or check giffgaff APN Settings for exact values.
  2. Verify the APN reads giffgaff.com exactly — no extra spaces, no http://, no typos.
  3. Check APN Type includes default and supl at minimum.
  4. Save, activate the profile, and restart your phone.

Step 4: Advanced Fixes

  1. Reset APN to default: On Android, in the APN list tap ⋮ › Reset to Default. On iPhone, Settings › General › Transfer or Reset iPhone › Reset Network Settings (note: this also removes saved Wi-Fi passwords).
  2. Check for carrier settings update: On iPhone, Settings › General › About. If an update is available, install it and restart.
  3. Update your phone's software — a pending OS update can occasionally cause APN issues.
  4. Try the SIM in another phone — if data works in a different device, the problem is software or settings on your original phone.
  5. Contact giffgaff support: community.giffgaff.com or the giffgaff app (no phone support). They can check whether there is a network-level issue with your account or SIM.
