What giffgaff APN settings do and when you need them
Several things stop giffgaff data, calls or texts: a bad APN, an area outage, a loose SIM, or a software glitch.
Troubleshooting checklist
Stick to the order given — later steps assume the earlier ones were already tried
Correct giffgaff APN values for internet and MMS
Rule out a giffgaff outage first via the hub or Downdetector; settings changes won't help while the network is down.
Troubleshooting checklist
Work down in sequence; each step builds on the one before
How to enter giffgaff APN on Android and iPhone
Toggle Aeroplane Mode from the notification shade for ten seconds — the phone drops and rebuilds its giffgaff connection.
Troubleshooting checklist
Follow the order, since later fixes assume the earlier ones failed
What to do if giffgaff APN does not save
A proper restart flushes the modem cache and forces giffgaff re-registration, fixing what aeroplane mode won't.
Troubleshooting checklist
Go in sequence — skipping ahead misses groundwork
Step 4 — Re-seat the SIM on giffgaff when resetting APN
Power down, pop the SIM tray with the tool or a paperclip, inspect and clean the contacts, then reinsert the giffgaff SIM securely.
Troubleshooting checklist
Each step assumes the previous one didn't help, so keep the order
Step 5 — Check giffgaff's APN settings when resetting APN
| Setting | Value |
|---|---|
| APN Name | giffgaff.com |
| Username | giffgaff |
| Password | password |
| MMSC | http://mmsc.mediamessaging.co.uk:8002 |
| MMS Proxy | 82.132.254.1 |
| MMS Port | 8080 |
| Authentication Type | PAP |
| APN Type | default,supl,mms |
Full signal with no data often points to a wrong APN — check Settings → Mobile Network → Access Point Names.
Troubleshooting checklist
Order matters here; don't jump to the end
Step 6 — Reset giffgaff's network settings when resetting APN
On Android, reset network settings to restore giffgaff defaults — saved Wi-Fi and Bluetooth go, apps and data stay.
On iOS, reset network settings via Settings → General → Transfer or Reset iPhone; giffgaff's defaults are restored.
Troubleshooting checklist
Take them in turn rather than skipping around
Step 7 — Contact giffgaff support when resetting APN
If nothing works, contact giffgaff. Bring your account number and IMEI; it may be an account, SIM or network-side problem.

The sequence matters — later steps build on earlier ones
