How to Fix Mobile Data Not Working While Calls Still Work
When iPhone calls work but data does not, restore cellular internet by checking the active data line, enabling Cellular Data, confirming carrier coverage and plan status, and refreshing network settings. A restart, Airplane Mode reset, or carrier update often resolves iPhone cellular data with no internet when signal bars remain visible.
Steps
- Confirm Cellular Data is enabled. Open Settings > Cellular and turn on Cellular Data. In a Dual SIM iPhone, select the correct line under Cellular Data.
- Check app-level data access. Scroll through the app list in Settings > Cellular and enable mobile data for Safari, messaging apps, maps, and other affected apps.
- Refresh the cellular connection. Turn on Airplane Mode for 30 seconds, turn Airplane Mode off, then restart the iPhone. A new network registration can restore data service.
- Install carrier settings. Open Settings > General > About and wait briefly for a carrier update prompt. Install the update if available.
- Reset network settings. Open Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. The process removes saved Wi-Fi passwords, VPN settings, and cellular network preferences.
🤔Note:
Resetting network settings does not delete personal photos, messages, apps, or contacts, but it does remove saved Wi-Fi passwords, VPN settings, and cellular network preferences.
Common Issues and Fixes
- Calls work but mobile data is blocked: A carrier data outage, unpaid balance, or expired plan may be responsible. Check the carrier account and service-status page.
- iPhone shows signal but no mobile data: A weak or congested LTE/5G connection can maintain calls while data fails. Move outdoors, test another location, or switch between 5G Auto, 5G On, and LTE under Settings > Cellular > Cellular Data Options.
- Data fails after changing SIM cards: Incorrect carrier settings or an inactive SIM may prevent internet access. Reseat the physical SIM or confirm eSIM activation with the carrier.
- Only one app lacks internet access: App-level cellular permission may be disabled. Enable the affected app under Settings > Cellular and reopen the app.
- Data stopped after an iOS update: A network configuration conflict may exist. Install pending iOS and carrier updates, then reset network settings if required.
Quick Tips
- Check the status-bar icon: 5G, LTE, or 4G should appear when mobile data is available.
- Disable Wi-Fi temporarily during testing. A connected but offline Wi-Fi network can make cellular data appear unavailable.
- VPN, security, and DNS apps can block mobile internet. Disable the affected service during troubleshooting.
- Roaming data requires Data Roaming under Settings > Cellular > Cellular Data Options and may create additional carrier charges.
💡Protip:
Disable Wi-Fi temporarily while testing cellular data, and check whether 5G, LTE, or 4G appears in the status bar. This helps distinguish a mobile network issue from an offline Wi-Fi connection.
Related Questions
Why does an iPhone have signal but no mobile data?
Signal bars indicate network registration, not active internet service. Carrier restrictions, congestion, incorrect APN settings, or a disabled data plan can stop mobile data while calls continue.
Does resetting network settings delete photos?
No. Network reset removes Wi-Fi passwords, VPN profiles, and cellular preferences, but personal photos, messages, apps, and contacts remain on the iPhone.
