Troubleshoot smartphone Internet access
Test Wi-Fi and mobile data separately and inspect data usage before changing advanced settings.

The answer in 30 seconds
A network icon does not prove that a connection reaches the Internet. Distinguishing Wi-Fi from mobile data makes a failure easier to locate.
Open a known page, then test Wi-Fi and mobile data separately. Check roaming and the data plan before using a mobile connection abroad.
Examples to adapt
Check mobile-data permission and plan status before changing the router.
Investigate the shared connection rather than resetting only the phone.
Follow the method
- 1Read the connection state
Identify Wi-Fi or mobile data and the network name. Open a known public page to confirm actual access.
- 2Choose the intended network
At home, use the recognised network. When travelling, check mobile-data and roaming conditions before assuming the connection is included.
- 3Inspect consumption
Read per-app data use and restrict unnecessary background transfers. Use low-data controls where available for a limited plan.
- 4Separate failure causes
Temporarily turn off Wi-Fi to test mobile data, then test Wi-Fi separately. Compare another device before resetting network settings.
- 5Maintain the device
Keep the system and browser updated, lock the screen and remove saved networks no longer needed. Follow official instructions for restarts.
A checklist to keep
Use these checks to record what you found. The grid supports a decision; it does not make one for you.
| Check | What to examine | Action |
|---|---|---|
| State | Wi-Fi or mobile network | Identify the active route |
| Access | Known public page | Check actual connectivity |
| Plan | Data allowance and roaming | Read current conditions |
| Failure | Other device and connection type | Isolate before resetting |

What to check
A signal icon is not a complete diagnosis.
Resetting network settings can remove saved configuration.
Do not share the Wi-Fi password in a public troubleshooting post.
Common questions
What should I test first?
One known page, then the two connection types separately.
Why inspect background use?
Backups and updates can consume a limited plan even when you are not actively reading a page.
