Why does my phone lose service after I leave home?
Answer
If a phone works at home but fails outside, it is often relying on Wi‑Fi calling at home while cellular signal is weak, barred, or misconfigured outdoors. Toggle Airplane mode, confirm mobile data/SIM status, and test with Wi‑Fi off to see whether the carrier network registers away from home.
Before you start: stop right away if…
- Deleting the eSIM can extend outage time if no replacement profile is ready.
Follow these steps
Test with Wi‑Fi off
Before leaving or after going outside, turn off Wi‑Fi and Wi‑Fi Calling temporarily and see whether the phone shows carrier signal bars or No Service.
You should see: You confirm whether the phone can use cellular alone.
Toggle Airplane mode outdoors
With Wi‑Fi off, turn Airplane mode on for 15 seconds, turn it off, and wait for the network name to return.
You should see: Signal returns, or No Service remains.
Set network selection to automatic
In Connections/Mobile network settings, set network operators to automatic, confirm the correct SIM is active, then restart the phone.
You should see: The phone reselects the carrier automatically.
Check carrier account and coverage
If No Service continues in areas that should have coverage, check the carrier app for line status and ask support to refresh provisioning; compare with another phone on the same network.
You should see: Service returns after a network refresh, or you identify a coverage/account issue.

Extra tips
What to look for: No Service or SOS only after leaving home, Wi‑Fi Calling enabled, and whether mobile data works with Wi‑Fi off
Before you change anything: Note whether calls still work at home only on Wi‑Fi. Test in another outdoor location before assuming total failure. Have the carrier account login ready. Do not delete the eSIM until the carrier advises a replacement.
