iMessage Is Signed Out on iPhone: How to Fix It
Fix the iMessage Is Signed Out error on iPhone by checking Apple Account sign-in, activation, connectivity, and settings—without erasing your messages.
To put an iPad in kiosk mode, use Guided Access for a quick, temporary one-app lock, or Single App Mode for a supervised iPad used as a point-of-sale terminal, check-in station, display, or other dedicated device. Guided Access can be configured directly on the iPad. Single App Mode is stronger and is intended for managed devices.
| Method | Best for | What you need |
|---|---|---|
| Guided Access | Temporary kiosk use, classrooms, demos, children, focus | Only the iPad |
| Single App Mode | Dedicated POS, reception, display, or shared business iPad | A supervised iPad plus Apple Configurator on a Mac, or device management |
| MDM App Lock | Multiple remotely managed kiosks | Supervised/managed devices and a device management service |
Apple describes Guided Access as a way to temporarily restrict iPad to a single app while controlling buttons, touch, motion, the software keyboard, and time limits. This is the simplest option when you do not need full device management. See Apple's Guided Access instructions.




Triple-click the Top button on an iPad with Face ID, or the Home button on models that have one. Enter the Guided Access passcode or authenticate with Face ID/Touch ID, depending on the options you enabled.
Single App Mode forces the selected app to stay open on a supervised device and prevents users from switching to other apps. Apple also states that the chosen app reopens after a restart. That makes it a better fit for unattended or continuously used kiosks. The current Apple Configurator workflow is documented in Apple's Single App Mode guide.
Important: iPads are not supervised by default. Apple says supervision is normally enabled during device setup on a new or fully erased device. If you are converting an already-configured personal iPad, back it up and review Apple's supervision guidance before proceeding. Removing supervision later erases the device.



To stop Single App Mode later, reconnect the iPad to the Mac, select it in Apple Configurator, and use Actions > Advanced > Stop Single App Mode.

If you manage a fleet of iPads, a device management service is more practical than connecting each unit to one Mac. Apple's App Lock payload can restrict a managed iPad to a single app and define additional kiosk-related controls. This approach is designed for organizational deployments and remote administration.
Use Guided Access when you need a quick one-app session without extra hardware. Use Single App Mode when the iPad is a supervised, dedicated kiosk that should return to the same app after restart. For many devices, manage Single App Mode through MDM instead of configuring each iPad manually.
