Ho un iPhone 7, dopo aver aggiornato iOS 12, perde il segnale cellulare, visualizza Nessun servizio con un'icona di avviso. E un avviso ha detto:
Cellular update failed
Your iPhone cannot make and recieve calls or access cellular data until it has been updated
Quindi cosa ha causato questo problema? Ho cercato su Google e ho ricevuto solo 1 post su questo, ma nessuna buona risposta su come risolverlo.
Verifica un aggiornamento delle impostazioni cellulari:
You can manually check for and install a carrier settings update with these steps:
Make sure your device is connected to a Wi-Fi or cellular network.
Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.
Prova aggiornando il tuo dispositivo:
Plug your device into power and connect to the Internet with Wi-Fi.
Tap Settings > General > Software Update.
Tap Download and Install. If a message asks to temporarily remove apps because iOS needs more space for the update, tap Continue or Cancel. Later, iOS will reinstall apps that it removed. If you tap Cancel, learn what to do next.
To update now, tap Install. Or you can tap Later and choose Install Tonight or Remind Me Later. If you tap Install Tonight, just plug your iOS device into power before you go to sleep. Your device will update automatically overnight.
