How do I fix email and banking apps that stop working on iPhone while calls still work?
Answer
When calls and texts still work but apps that need the internet fail, the iPhone usually has a data or Wi‑Fi problem rather than a carrier voice outage. Toggle Airplane Mode, confirm Cellular Data is on for those apps, then try mobile data with Wi‑Fi off to see which path is broken.
Follow these steps
Refresh the wireless radios
Open Control Center, turn on Airplane Mode for about 30 seconds, then turn it off and wait for the signal and Wi‑Fi icons to return.
You should see: The phone reconnects to cellular and Wi‑Fi, and apps may start loading again.
Confirm cellular data is allowed
Go to Settings > Cellular and make sure Cellular Data is on. Then open Cellular Data options for Mail and your banking apps and confirm they are allowed to use cellular data.
You should see: Cellular Data is enabled and those apps are not blocked from using mobile data.
Test mobile data without Wi‑Fi
Go to Settings > Wi‑Fi and turn Wi‑Fi off. Open Safari and try a simple website, then try email and the banking app again.
You should see: If apps work on mobile data alone, the home Wi‑Fi or router path is the problem.
Reconnect to a working Wi‑Fi network
Turn Wi‑Fi back on, forget the home network if needed (Settings > Wi‑Fi > info icon > Forget This Network), then reconnect with the correct password. Restart the router once more only after that test.
You should see: The iPhone shows a solid Wi‑Fi connection and internet apps load on Wi‑Fi again.
Restart the iPhone
If apps still fail on both Wi‑Fi and mobile data, power the iPhone fully off, wait 30 seconds, turn it back on, and retest Mail and the banking app.
You should see: The apps open and sync without a stuck loading screen.

Extra tips
What to look for: Whether Safari or other internet apps also fail, whether Cellular Data is enabled, and whether the Wi‑Fi icon shows connected with no actual page loading.
Before you change anything: Note whether other internet apps fail the same way as email and banking. Avoid signing out of banking apps or deleting accounts while testing connectivity. Confirm you are using the official email and banking apps from the App Store. Never share passwords or one-time codes with unexpected callers.
