Quick answer: on Android open Access Point Names, tap the three dots menu and choose Reset to default. On iPhone go to Settings -> Mobile Service -> Mobile Data Network -> Reset Settings.

Write down any APN you typed in yourself before you reset; it will be deleted.

Samsung Galaxy (One UI)

Settings -> Connections -> Mobile networks -> Access Point Names -> three dots (top right) -> Reset to default

Google Pixel and stock Android

Settings -> Network & internet -> SIMs -> choose the SIM -> Access point names -> three dots -> Reset to default

Xiaomi, Redmi and POCO (HyperOS / MIUI)

Settings -> SIM cards & mobile networks (Mobile networks) -> choose the SIM -> Access point names -> Reset (at the bottom of the list)

Oppo, Realme and OnePlus (ColorOS / realme UI / OxygenOS)

Settings -> Mobile network -> SIM 1 or SIM 2 -> Access point names (APN) -> three dots -> Reset to default

Vivo and iQOO (Funtouch OS / OriginOS)

Settings -> Mobile network -> SIM 1 or SIM 2 -> Access Point Names (APN) -> three dots -> Reset to default

iPhone and iPad

  • APN fields only: Settings -> Mobile Service (Cellular) -> Mobile Data Network -> Reset Settings (at the bottom of the page).
  • Everything network related, including Wi-Fi passwords: Settings -> General -> Transfer or Reset iPhone -> Reset -> Reset Network Settings.

After the reset

  • Check that the carrier APN is selected in the list, then switch Airplane mode on and off.
  • If the list is empty after the reset, restart the phone with the SIM inside; the APN is loaded when the SIM registers.
  • If data still does not work, go through Mobile Data Not Working After Adding APN.
  • Some phones also have Reset mobile network settings under Settings -> General management (Samsung) or Settings -> System -> Reset options (Pixel). It resets mobile settings without touching Wi-Fi.
