ASDA Mobile Internet Not Working Fix Guide
This checklist works through the most common causes in order of likelihood, starting with the fastest checks. Most EE-network data faults clear up in step 1 or 2 — the later steps cover the less common cases.
As an MVNO, Asda Mobile doesn't operate its own masts — it buys wholesale access to EE's infrastructure. That means an EE network outage will affect Asda Mobile too, and the fastest way to confirm a wider problem is to check EE's live status page rather than assuming it's a fault with your phone.

Step 1: Check for ASDA Mobile Network Outage
Before changing any settings, check whether ASDA Mobile is experiencing a network outage in your area. An outage is the most common reason for sudden mobile data loss across an area.
If there is a confirmed outage in your area, no settings changes will help — wait for ASDA Mobile 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 Asda Mobile Fixes to Try First
Five checks, done properly, resolve most ASDA Mobile data faults in under two minutes — work through them in order rather than skipping ahead.
- Aeroplane Mode, 30 seconds on, then off — this forces your phone to drop and re-register its connection, clearing most temporary registration faults.
- Full restart — powering off completely (not just locking the screen) clears the network stack and reloads your APN settings from scratch.
- Confirm Mobile Data is actually on — check Settings › Mobile Data (iPhone) or Settings › Connections › Mobile Data (Android); it's easy to knock this off by accident.
- Check your remaining allowance in My ASDA Mobile — a used-up data allowance is throttled or cut off entirely, and it's often mistaken for a network fault.
- Reseat the SIM — power off first, then remove and refit the SIM card; a loose contact causes intermittent, hard-to-diagnose drops.
Step 3: Verify ASDA Mobile APN Settings
An incorrect APN is among the most common causes of data failure — it commonly happens after a factory reset, an OS update, a SIM swap, or moving from a different network. Check and re-enter it if needed.
How to check APN settings on Android
- Open Settings › Connections › Mobile Networks › Access Point Names (Samsung) or Settings › Network & internet › Mobile network › Access point names (Pixel).
- Find the ASDA Mobile APN entry, tap it, and confirm the field reads exactly everywhere — no stray spaces or extra characters.
- Check that APN Type includes at least default and supl.
- If there's no ASDA Mobile APN, or the values look wrong, the full ASDA Mobile APN settings guide has everything you need.
- Save, tap the radio button to activate the profile, then restart your phone.
How to check on iPhone
- Go to Settings › Mobile Data › Mobile Data Network (if it's shown).
- Confirm the APN field shows everywhere.
- Greyed out means it's controlled by the carrier bundle — check Settings › General › About for a carrier settings update.
Step 4 — More Advanced Asda Mobile Fixes
- Start by trying a different SIM in your phone — if another SIM connects fine, the fault sits with your ASDA Mobile SIM or account rather than the handset.
- Then try your SIM in a different phone — if data works there, the problem is software or hardware specific to your original device.
- Reset network settings: Android — open APN settings, tap ⋮ › Reset to Default. iPhone — Settings › General › Transfer or Reset iPhone › Reset › Reset Network Settings. This also clears saved Wi-Fi passwords, so note them down first.
- On iPhone, check for a carrier settings update: Settings › General › About — install any update offered and restart.
- Check for a pending OS update under Settings › System › Software Update, since an outdated OS can occasionally interfere with network registration.
- Ask for a SIM replacement if none of the above helps — SIMs degrade physically over time, and a free replacement rules this out.
- Call ASDA Mobile support on 0333 200 7777 or ASDA Mobile website if you're still stuck — they can check account status and whether there's a known issue with the mast nearest you.
Common Causes of ASDA Mobile Data Not Working
| Symptom | Likely Cause | Fix |
|---|---|---|
| After iOS/Android update | OS update overwrote network settings | Reset network settings and re-enter APN |
| Sudden data loss, was working before | Network outage or SIM registration issue | Check status page; toggle Aeroplane Mode |
| Works on Wi-Fi but not mobile data | Mobile data toggle off or APN wrong | Enable mobile data in Settings; verify APN |
| After factory reset / phone change | APN settings not transferred | Re-enter APN settings: everywhere |
| Data works then stops randomly | Poor signal, congestion, or SIM contact issue | Reseat SIM; check coverage map |
| Very slow speeds (not outright broken) | Data throttling, network congestion | Check if data cap hit; try different time of day |
| Signal bars showing but no internet | Incorrect APN or data plan expired | Verify APN; check data balance in My ASDA Mobile |
