Recent Tesco Mobile outages
We haven't recorded any Tesco Mobile outages since we started keeping this history on 24 October 2026. We record one when our checks of tescomobile.com fail for 15 minutes in a row, when problem reports jump well above normal, or when Tesco Mobile's official status page reports a major outage.
Times are in UTC. Each entry is a time when our checks failed for at least 15 minutes, problem reports jumped well above normal, or Tesco Mobile's status page reported a major outage.
How Tesco Mobile outages usually look
Tesco Mobile has two separate things that can go down: the mobile network, and the website and app you use to manage your account. Our check tests the website, so it can show Tesco Mobile as up while your phone has no bars. The network is O2's. Tesco Mobile describes itself as powered by O2's network, which means a mast fault or a wider O2 outage hits Tesco Mobile customers in the same places at the same time. Tesco Mobile has its own status checker, where you enter a postcode to see known issues or planned work, with live updates for calls, texts and data.
Some lost service is not a fault at all. 3G has been switched off, so a phone or SIM that can't use 4G will struggle. From 23 February 2026 Tesco Mobile also began disconnecting two groups of pay as you go customers as it replaced an old platform: those still on a 2G SIM, and numbers with no chargeable activity for a long time. Affected customers were sent a text, letter or email with a deadline. Tesco Mobile says a number disconnected within the last 30 days may be reconnected, so act quickly if this is you.
Common Tesco Mobile errors and what they mean
No signal, or calls and data fail in one area
Most often a local mast fault or planned work on the O2 network that Tesco Mobile uses. It affects everyone nearby on Tesco Mobile and O2.
What to do: Enter your postcode in Tesco Mobile's status checker over Wi-Fi. If work is listed, turn on Wi-Fi calling so calls and texts go over your broadband until it's finished.
No 4G, only a weak or missing connection
With 3G switched off, a handset or setting that doesn't allow 4G leaves you with very little. Coverage also varies, and the coverage checker is based on predictions.
What to do: Check your phone supports 4G and that 4G is enabled in its mobile network settings. Then check the status checker and the coverage checker for your postcode.
Pay as you go SIM has stopped working completely
Possibly a disconnection, not an outage. From 23 February 2026 Tesco Mobile disconnected 2G SIMs and long-inactive numbers that were not moved to its new platform.
What to do: Contact Tesco Mobile or visit a Tesco Phone Shop as soon as you can. A number disconnected in the last 30 days may be reconnected by moving it to a Pay as you go Essentials SIM.
Calls drop or sound poor indoors
Weak indoor signal, not a network outage. Thick walls and distance from a mast are the usual cause.
What to do: Turn on Wi-Fi calling and 4G Calling in your phone's settings. Tesco Mobile has set-up steps for each handset on support.tescomobile.com.
Website or app won't let you sign in or top up
An account system problem. Your calls, texts and data carry on working because the network is separate.
What to do: Try the website if the app fails, or the app if the website fails. For anything urgent, call 4455 free from your Tesco Mobile phone.
What to do if Tesco Mobile is not working
- Use the status checker at tescomobile.com/status-checker before changing any settings. It lists known faults and planned work for your postcode.
- Ask someone nearby on O2 whether they have signal. Tesco Mobile uses the same masts, so if O2 is out locally, Tesco Mobile is too.
- Turn on Wi-Fi calling so you can still call and text at home during mast work. Messages sent as RCS or iMessage also go over Wi-Fi.
- Restart the phone or switch airplane mode on and off after a fault is fixed. Phones don't always reconnect to the network by themselves.
- Call Customer Care and technical support on 4455 from your Tesco Mobile, or 0345 301 4455 from another phone if yours has no service.
- If you want to leave or need your number moved, text PAC to 65075 for free. The code is valid for 30 days.
- Tesco Mobile is run separately from Tesco groceries and Tesco Bank. A problem with tesco.com or your Clubcard app has nothing to do with your signal.

Tesco Mobile outage FAQ
Is Tesco Mobile down for everyone, or just me?
Look at the status at the top of this page. We connect to tescomobile.com directly from our servers, so if our check works but Tesco Mobile doesn't work for you, the problem is more likely your device, network or account. If our check fails, or reports have jumped in the last hour, Tesco Mobile is probably having a wider outage.
Why does this page say Tesco Mobile is up when it isn't working for me?
Our check confirms that tescomobile.com is reachable and responding. An outage can still affect only part of Tesco Mobile, such as logging in, the mobile app or a single feature, or only some regions. That's why visitor reports matter: when many people report problems at once, we flag Tesco Mobile as having problems even if the website loads.
How often do you check Tesco Mobile?
We check Tesco Mobile automatically every 5 minutes, and again whenever someone opens this page and our last check is more than a few minutes old. A failed check is retried once before it counts.
How do I report a problem with Tesco Mobile?
Use "Report a problem" on this page to tell us what isn't working. Reports are anonymous: we don't store your IP address, only a one-way code that stops the same person reporting many times, plus your country.
Which network does Tesco Mobile use?
O2's. Tesco Mobile says it is powered by O2's network, so coverage and network faults are the same as O2's in any given place. Billing, customer service and the app are Tesco Mobile's own.
Why was my Tesco Mobile number disconnected?
From 23 February 2026 Tesco Mobile began disconnecting pay as you go customers still on a 2G SIM and numbers with no chargeable activity for a long time, as part of replacing an old platform. If it was within the last 30 days, contact Tesco Mobile or visit a Phone Shop, as the number may be reconnected. You can also ask for a refund of unused credit.
Is Tesco Mobile down if tesco.com is down?
No. The supermarket website and the mobile network are separate. Your calls and data depend on O2's network, and your account pages are on tescomobile.com, so a grocery site outage doesn't affect either.
