The APN is what lets a phone talk to Tesco Mobile's network for data, MMS and hotspot. Get it wrong and pages won't load.
These are Tesco Mobile's suggested APN settings across both platforms. If data connects but pages won't load, check the APN first.

Saving an APN does not activate it — you must select it
On Android, after tapping Save the new APN appears in the list but is not yet active. Tap the radio button (empty circle) next to it so it becomes filled. The profile is only active when the circle is filled. Then toggle aeroplane mode or restart.
Optimising your Tesco Mobile APN for 4G and 5G
For iOS 16 onward, look under Settings → Mobile Data → Mobile Data Network. Its absence means Tesco Mobile handles the APN automatically.
Heads up: Tesco Mobile's carrier bundle can disable the APN field on newer iPhones.

APN field greyed out? Here is why
On Android: the field is locked by a carrier profile. Go to Settings → Network & Internet → Mobile Network → Access Point Names and tap Reset to Default (three-dot menu). On iPhone: the carrier bundle controls the APN — it cannot be edited manually. Contact your network to push an updated carrier profile, or insert the SIM in another phone to test.

APN values are case-sensitive — enter them exactly
Type every character exactly as shown — no spaces before or after, no capital letters unless listed. One wrong character stops mobile data from working. After saving on Android, tap the radio button (filled circle) next to the new profile to activate it.

Fastest way to apply new APN settings
After saving, turn aeroplane mode ON for 10 seconds, then turn it OFF. This forces an immediate network re-registration — quicker than a full restart and equally effective.
Troubleshooting Tesco Mobile APN issues
If Tesco Mobile's APN values haven't fixed it, run through the following:
1. Switch aeroplane mode on briefly then off, forcing reconnection to Tesco Mobile.
2. Cycling the power clears transient network faults.
3. Build the profile again from scratch, as a single typo is a frequent cause of failure.
4. Wipe network settings entirely; Tesco Mobile's default APN is restored afterwards.
5. Look at the account side. Activation and remaining allowance can be checked through Tesco Mobile's hub.

Common MMS mistakes that stop picture messages working
• The MMSC URL must begin with http:// — never https://
• The MMS Proxy field is an IP address only — no http:// prefix
• APN Type must contain mms (e.g. default,supl,mms)
• On Android, save then select the profile before testing
APN settings for MMS on Tesco Mobile
Picture messages rely on separate MMSC, proxy and port values in the APN. If MMS fails, start there — certain Android models split this into its own APN entry.
