- Wait 10 seconds, then disable it.
This quick step often resolves the iPhone cellular data not working issue. Apple’s support page on Airplane Mode provides more insights into how this feature works.
4. Update Carrier Settings
Carrier settings updates can help improve connectivity. To check for updates:
- Go to Settings > General > About.
- If an update prompt appears, follow the steps to install it.
Carrier settings updates can be essential for maintaining connectivity. You can learn more on Apple’s guide to carrier settings updates.
5. Reinsert the SIM Card
Removing and reinserting the SIM card can re-establish the network connection:
- Turn off your iPhone.
- Use a SIM eject tool or paperclip to remove the SIM card.
- Reinsert it carefully and power on your iPhone.
