Lycamobile Internet Not Working Fix Guide
Ordered quick-to-involved, this O2 list resolves most faults in the first two steps — worth trying before a SIM or account fix.
Lycamobile does not operate its own mobile masts in the UK — it buys wholesale network access from one of the major UK operators. If the steps below don't resolve the issue, it's worth checking whether the underlying host network is reporting a wider outage.

Step 1: Check for Lycamobile Network Outage
Before changing any settings, check whether Lycamobile is experiencing a network outage in your area. An outage is the most common reason for sudden mobile data loss across an area.
Check Lycamobile status: https://www.lycamobile.co.uk
If there is a confirmed outage in your area, no settings changes will help — wait for Lycamobile to restore the network and check the status page for estimated recovery time. You can also check Downdetector for user-reported issues.
Step 2 — Quick Lyca Fixes to Try First
Try this shortlist before touching any settings — it clears the majority of Lycamobile data issues on its own.
- Check your data balance in My Lyca Mobile first — an exhausted allowance is the single most common cause of "data not working" reports, and it's the quickest thing to rule out.
- Switch Aeroplane Mode on for 30 seconds, then off, forcing a clean reconnection to the network.
- Make sure Mobile Data is switched on: Settings › Mobile Data (iPhone) or Settings › Connections › Mobile Data (Android).
- A proper restart, not just a screen lock/unlock, fully reloads the network settings.
- Power off, then remove and reinsert the SIM — a poor contact can cause unpredictable data drops.
Step 3: Verify Lycamobile APN Settings
A mistaken APN is a very common reason for data to stop working, particularly after a factory reset, OS update, SIM swap, or switching networks. Worth checking and re-entering if it looks off.
Correct Lycamobile APN: data.lycamobile.co.uk
How to check APN settings on Android
- Head to Settings › Connections › Mobile Networks › Access Point Names (Samsung) or Settings › Network & internet › Mobile network › Access point names (Pixel).
- Look for the Lycamobile APN, tap in, and check it reads exactly data.lycamobile.co.uk — no extra spaces or typos.
- Make sure APN Type includes at minimum default and supl.
- Missing or wrong values? See the full Lycamobile APN settings guide for the complete set.
- Save it, activate via the radio button, then restart.
How to check on iPhone
- Go to Settings › Mobile Data › Mobile Data Network, if that option's visible.
- Check the APN field shows data.lycamobile.co.uk.
- If it's greyed out, that's the carrier bundle in control — check Settings › General › About for an update.
Step 4 — More Advanced Lyca Fixes
- Next, reset network settings: on Android, open APN settings and tap ⋮ › Reset to Default; on iPhone, go to Settings › General › Transfer or Reset iPhone › Reset › Reset Network Settings. Note: your saved Wi-Fi passwords will be cleared too.
- Before anything else, iPhone users should check Settings › General › About for a carrier update — quick, and sometimes fixes it outright.
- Check Settings › System › Software Update for a pending OS update and install it.
- Moving the SIM to another phone reveals whether the fault follows the SIM or the handset.
- Put a different SIM into your own phone as the reverse test — if that works, the issue is your Lycamobile SIM or account rather than the device.
- A free SIM replacement is worth requesting if the fault persists, since SIM wear does happen occasionally.
- Call Lycamobile on 322 (free from Lycamobile) or 0203 441 5161 for an account- or mast-level check if nothing above resolves it.
Common Causes of Lycamobile Data Not Working
| Symptom | Likely Cause | Fix |
|---|---|---|
| Works on Wi-Fi but not mobile data | Mobile data toggle off or APN wrong | Enable mobile data in Settings; verify APN |
| Data works then stops randomly | Poor signal, congestion, or SIM contact issue | Reseat SIM; check coverage map |
| After factory reset / phone change | APN settings not transferred | Re-enter APN settings: data.lycamobile.co.uk |
| Very slow speeds (not outright broken) | Data throttling, network congestion | Check if data cap hit; try different time of day |
| After iOS/Android update | OS update overwrote network settings | Reset network settings and re-enter APN |
| Signal bars showing but no internet | Incorrect APN or data plan expired | Verify APN; check data balance in My Lyca Mobile |
| Sudden data loss, was working before | Network outage or SIM registration issue | Check status page; toggle Aeroplane Mode |
Frequently Asked Questions — Lycamobile Internet Not Working
How do I fix Lycamobile mobile data not working?
Flip Aeroplane Mode on for 30 seconds, then off — this alone fixes a surprising number of cases by forcing re-registration. If that doesn't help, visit Settings › Mobile Networks › Access Point Names and check the APN matches data.lycamobile.co.uk exactly. It's also sensible to rule out an outage at https://www.lycamobile.co.uk before troubleshooting further. If none of that works, restart the phone fully and re-enter the APN.
What is the Lycamobile APN for mobile data?
data.lycamobile.co.uk is the figure to use. For the complete set of fields (not just the APN name), see the Lycamobile APN settings guide, which also covers MMS setup.
Is Lycamobile down right now?
Verify via https://www.lycamobile.co.uk for Lycamobile's own real-time status. If that shows nothing but you're still convinced it's wider than just your phone, Downdetector's user reports can confirm or rule that out.
Why does Lycamobile show signal but no internet?
Having signal confirms the mast link only, not a working data session — those are two separate things. Check off each of these: Mobile Data enabled in Settings, the APN reading exactly data.lycamobile.co.uk, your plan still having data left, and no outage currently affecting your area.
How do I reset Lycamobile APN settings?
On Android, access APN settings and use the ⋮ menu to Reset to Default. On iPhone, it's Settings › General › Transfer or Reset iPhone › Reset › Reset Network Settings (note: Wi-Fi passwords get cleared too). Re-enter data.lycamobile.co.uk once the reset is done.
Lycamobile data stopped working after a phone update — what do I do?
It occurs fairly often after major updates. Head to Settings › Mobile Networks › Access Point Names and re-enter data.lycamobile.co.uk. iPhone users should also check for a carrier settings update at Settings › General › About, then restart the phone.
