How do I fix a phone that cannot make calls or send texts?
Answer
Toggle Airplane Mode, restart the phone, and confirm cellular signal—not just Wi-Fi. Then reseat the SIM or check eSIM status and contact the carrier if No Service continues.
Before you start: stop right away if…
- Do not install carrier settings from unofficial websites.
Follow these steps
Toggle Airplane Mode
Turn Airplane Mode on for 15 seconds, then turn it off. Wait for signal bars and a carrier name to return.
You should see: Cellular service reappears, or No Service remains.
Restart the phone
Power the phone fully off, wait 30 seconds, then turn it back on and check signal again.
You should see: The phone reregisters on the network or still shows no cellular service.
Check SIM or eSIM
For a physical SIM, power off and reseat the card. For eSIM, open network or mobile settings and confirm the line is turned on. Try calling your own voicemail or texting your own number with a full 10-digit number.
You should see: Calls or texts start working, or the line still fails.
Contact the carrier
If No Service continues, contact the carrier from another phone or chat on Wi-Fi. Ask them to check outages, account suspension, and SIM provisioning.
You should see: The carrier restores the line or provides a replacement SIM/eSIM.

Extra tips
What to look for: No Service or missing carrier name, failed calls, and failed SMS at the same time.
Before you change anything: Note whether Wi-Fi calling is on. Have the account phone number ready for carrier chat. Avoid random APN downloads from unofficial sites.
