Tesco Mobile APN Settings for UK

Runs on O2 network 4G LTE

Last verified: July 2025

Tesco Mobile is a UK MVNO jointly owned by Tesco and Virgin Media O2 (Telefónica). It is one of the UK's most popular budget mobile networks, offering pay-as-you-go and monthly plans with data rollover. Tesco Mobile runs on the O2 network, which means it shares O2's nationwide 4G coverage. Tesco Mobile does not currently support 5G. Unlike O2 itself, Tesco Mobile's APN — prepay.tesco-mobile.co.uk — requires no username or password, making setup simpler. Tesco Mobile SIMs are often sold pre-activated in Tesco stores and may come with configuration pre-loaded, but if you insert the SIM in an older or factory-reset phone, you'll need to enter these settings manually.

Tesco Mobile APN Troubleshooting

Remove and reinsert your SIM to reset the configuration lock. Check for any pending OTA configuration messages from Tesco Mobile. If using a Samsung, try Settings → General Management → Reset → Reset Network Settings.
Verify the APN is exactly prepay.tesco-mobile.co.uk — note it begins with 'prepay' even for monthly contracts. Confirm mobile data is toggled on. Check your Tesco Mobile balance or plan is active using the My Tesco Mobile app.
Tesco Mobile shares O2's MMS infrastructure. Check MMSC is http://mmsc.mms.o2.co.uk:8002 and proxy is 82.132.254.1. Port should be 8080. Disable Wi-Fi when testing MMS as it requires mobile data.
Contact Tesco Mobile support and ask them to disable OTA configuration pushes. A SIM replacement can sometimes resolve persistent resetting issues.
Verify MCC 234 and MNC 10 are both correct. Tesco Mobile uses O2's network (MNC 10). Wrong MNC values are a common cause of 'no service' after manual APN entry.
