Tesco Mobile not working? Try this

Tesco Mobile provides mobile service on the O2 network.

Find out whether Tesco Mobile knows about an outage at your address

  1. Sign in to the Tesco Mobile app on mobile data. Known outages for your address are shown on the first screen.
  2. Look at the report chart on this page. A sudden jump in the last hour means other Tesco Mobile customers are affected too.
  3. Tesco Mobile runs on the O2 network, so also check the O2 page linked under "Check a related service".

No signal or no data on Tesco Mobile

  1. Switch airplane mode on for 10 seconds and off again. This forces the phone to register with the network from scratch.
  2. Restart the phone. If it shows "SOS" or "Emergency calls only", the SIM is not being accepted by the network.
  3. Calls work but data does not? Open Settings, turn mobile data off and on, and check the APN matches the one in Tesco Mobile's help pages.
  4. Tesco Mobile uses O2's masts. If O2 has an outage in your area, Tesco Mobile will be down as well and resetting your phone will not help.
  5. Take the SIM out, wipe it and reseat it, or toggle the eSIM off and on in Settings.

Work out whether it is the internet or just your Wi-Fi

  1. Try a different app or website. If only one app fails, that app is down, not your provider.
  2. Test more than one device. One failing device points to that device.
  3. Turn off any VPN and try again.

Tesco Mobile outage questions

Is Tesco Mobile down right now?

The status at the top of this page is updated every few minutes from automated checks of Tesco Mobile's systems and from visitor reports. Our checks reach Tesco Mobile's website and sign-in servers, so a local line or mast fault in one neighbourhood shows up first in the report chart rather than in the checks.

How do I check for a Tesco Mobile outage in my area?

Use the Tesco Mobile app, which shows faults for your own address or postcode. Then compare with the reports on this page to see whether other customers are affected.

Which network does Tesco Mobile use?

Tesco Mobile runs on the O2 network. When O2 has a fault, Tesco Mobile customers in the same area lose service as well.

Does Tesco Mobile pay compensation for outages?

Mobile networks are not part of Ofcom's automatic compensation scheme. If Tesco Mobile stays down, ask for a goodwill credit, and if the complaint is not settled after eight weeks you can take it to the ombudsman scheme Tesco Mobile belongs to.

How long do Tesco Mobile outages usually last?

Most faults are cleared within a few hours. Damage to cables from storms or construction can take a day or more, because a crew has to repair the line by hand.
