Correct Sky Mobile APN settings for all UK devices — internet, MMS, 5G and data values. Full setup guide for Android and iPhone, verified 2026.
What Sky Mobile APN settings do and when you need them
There are several common reasons why Sky Mobile mobile data, calls or texts might stop working. These include an incorrect APN configuration, a temporary network outage in your area, a SIM card that needs re-seating, or a software issue on your device. This guide walks through each possible cause and the fix for each one.

Correct Sky Mobile APN values for internet and MMS
Before changing any settings, visit the Sky Mobile APN hub or check a third-party site like Downdetector to confirm whether there is a known Sky Mobile outage in your area. If the network is down, you simply need to wait for Sky Mobile to restore service — no settings changes will help during an active outage.

How to enter Sky Mobile APN on Android and iPhone
Pull down your notification shade and tap Aeroplane Mode to enable it. Wait ten seconds, then tap again to disable it. This forces your phone to drop its current connection and reconnect fresh to the Sky Mobile mast. This fixes the majority of temporary signal and data issues.

What to do if Sky Mobile APN does not save
Hold the power button and select Restart. A full restart clears the modem cache and re-registers your SIM on the Sky Mobile network. This fixes many data and signal issues that toggling aeroplane mode does not resolve.

Step 4 — Re-seat your SIM card
Power off your phone completely. Use a SIM ejector tool or a straightened paperclip to open the SIM tray. Remove the SIM card, inspect the gold contacts for dirt or corrosion, and gently clean them with a dry cloth if necessary. Reinsert the SIM firmly and power the phone back on.

An incorrect APN is a common cause of mobile data not working even when you have signal. Go to Settings → Mobile Network → Access Point Names and verify the APN values match the Sky Mobile recommended settings. Visit the Sky Mobile APN hub for the correct values, or search this blog for the Sky Mobile APN guide for your specific device.

Reset Network Settings will delete all saved Wi-Fi passwords
This step also removes all Bluetooth pairings and VPN profiles. Make a note of your Wi-Fi passwords before continuing. Only use this as a last resort after all other steps have failed.
Step 6 — Reset network settings
On Android: Go to Settings → General Management → Reset → Reset Network Settings. This restores default APN settings, clears saved Wi-Fi networks and resets Bluetooth — it does not delete your apps or personal data.
On iPhone: Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. Your iPhone will restart and reconnect to Sky Mobile with default settings.

Step 7 — Contact Sky Mobile support
If none of the above steps resolve the issue, contact Sky Mobile customer support. There may be a problem with your account, your SIM may need replacing, or there may be a localised network fault. Have your account number and phone IMEI ready (dial *#06# to find your IMEI). Visit the Sky Mobile APN hub for contact details.
The Sky Mobile APN name is shown in the settings table above. On most Sky Mobile SIMs in the UK, the APN is pre-configured automatically when you insert your SIM.
Why is my Sky Mobile mobile data not working after entering the APN?
After entering the Sky Mobile APN settings, restart your phone to apply the changes. If data still does not work, check you have selected the correct APN and that your Sky Mobile plan includes mobile data.
Do I need to enter APN settings manually on Sky Mobile?
Most Sky Mobile devices configure APN settings automatically when you insert your SIM. You only need to enter them manually if your internet or MMS stops working after a factory reset or SIM swap.
What is the Sky Mobile MMS APN for picture messages?
The Sky Mobile MMS APN settings are included in the table above. Make sure the MMSC, MMS Proxy and MMS Port values are entered exactly as shown.
Can I use the same APN settings for 4G and 5G on Sky Mobile?
Yes, the Sky Mobile APN settings work for both 4G and 5G connections. You do not need a separate APN for 5G — the network upgrades automatically where 5G coverage is available.
