What Are The Causes of Samsung Galaxy S23 Ultra Mobile Hotspot Not Working?

First, let’s identify some possible causes of the Samsung Galaxy S23 Ultra’s mobile Hotspot not working before we get into solutions. If you understand the root cause of the problem, you can avoid spending time and energy on fixes that aren’t relevant or ineffective.

Mobile Hotspot is Disabled or Not Turned On: Mobile Hotspot is not enabled or activated on Samsung Galaxy S23 Ultra may not work due to this reason. In Settings > Connections > Mobile Hotspot and Tethering, toggle the On switch next to Mobile Hotspot to enable the Hotspot. In case the Hotspot doesn’t work after turning the switch on and off, try turning it off and on again.

Insufficient Data or Signal Strength: If your phone’s data plan or network signal is too weak or limited, it may cause problems with mobile hotspots. In Settings > Connections > Data usage, you can view your data usage and plan details and see if you’ve exceeded your monthly data allowance. Switching to a new location with better network coverage or using a WiFi network instead of mobile data may also be a good idea.

Network Carrier Restrictions or Settings: Your Samsung Galaxy S23 Ultra mobile hotspot might be restricted or configured differently by your carrier.

Software Glitches or Conflicts: Samsung Galaxy S23 Ultra’s mobile hotspot function may experience bugs, conflicts, or errors due to software. Outdated software versions, incompatible apps or settings, or corrupted system files may cause these issues. Go to Settings > Software update > Download and install to update your phone’s software. If any problematic data or settings are left behind, you can also perform a factory reset or clear the cache partition.

Fix 1: Restart your Samsung Galaxy S23 Ultra

You can resolve many electronic problems by restarting the device, including problems with mobile hotspots. Refreshing the system may result in the removal of temporary data, clearing caches, and reconnecting to the network. Now, press and hold the power button until you see the power menu, then tap Restart to restart your Samsung Galaxy S23 Ultra.

Fix 2: Check Your Mobile Hotspot Settings and Password

Check your hotspot settings if your mobile Hotspot is turned on, but other devices still have trouble connecting or accessing the internet. Ensure the hotspot name and password are correctly entered and visible to all devices. In Settings > Connections > Mobile Hotspot and Tethering > Mobile Hotspot > More > Reset to default, you can also try changing the password to one that is simpler or stronger or resetting the hotspot settings to default.

Fix 3: Disable Battery Optimization for Mobile Hotspot

When the battery level is low, the Samsung Galaxy S23 Ultra mobile Hotspot may be affected by battery optimization settings, limiting its performance or turning it off. Delete the optimization for Mobile Hotspot by going to Settings > Battery and device care > Battery > App power management > More options > Optimize battery usage > All apps; then go back to Settings > Battery and device care > Battery > App power management > More options > Optimize battery usage > All apps.

Fix 4: Update or Uninstall Incompatible Apps

There is a possibility that some apps that you installed or updated recently might conflict with the mobile hotspot function and cause errors or crashes on your Samsung Galaxy S23 Ultra. It may be a good idea to update the apps to the latest versions or to uninstall them temporarily to see if the Hotspot will work without them. Using Settings > Apps > App permissions > Mobile Hotspot, you can check if any apps are blocking your mobile Hotspot.

Fix 5: Clear Cache Partition or Perform a Factory Reset

It may be necessary to perform more advanced troubleshooting steps, such as clearing the cache partition or doing a factory reset, if none of the above solutions works for you. It is possible to remove temporary data or files that may be causing conflicts or errors on your Samsung Galaxy S23 Ultra by clearing its cache partition. Restoring the device to its factory settings is also possible by clearing its cache partition. Remember to back up your important data and files if you plan to perform a factory reset.

To perform a factory reset, follow these steps:

Select Settings > General management > Reset> Factory Data Reset.
Once you have read the information and warnings, tap Reset.
Tap Delete all after entering your PIN, password, or pattern.

Fix 6: Disable VPN or Proxy Settings

VPN or proxy settings may interfere with the mobile hotspot function on a Samsung Galaxy S23 Ultra, preventing other devices from accessing the internet. Go to Settings > Connections > More connection settings > VPN or Proxy, and then toggle off the switch or remove the configurations to temporarily disable VPN or proxy settings. You can also try to see if a different VPN or proxy service works better.

Fix 7: Check for Carrier Updates or Restrictions

Samsung Galaxy S23 Ultra, mobile hotspot functionality, may be restricted or updated depending on your carrier and region. To determine if your device is eligible for carrier updates, go to Settings > Software update > Download and install. If your carrier has information about mobile hotspot settings or limitations, you can contact them or check their website.

Fix 8: Change the Network Type or Frequency Band

See if you can improve the signal strength or stability by changing the network type or frequency band. Select the appropriate carrier and region from the list in Settings > Connections > Mobile networks > Network mode.

Fix 9: Reset Network Settings

You could have unintentionally affected the mobile hotspot function of your Samsung Galaxy S23 Ultra by making any changes to the network settings. First, go to Settings > General management > Reset> Reset network settings, then confirm that the settings will be reset to their defaults. After doing this, you will need to reset up all network configurations, including WiFi, Bluetooth, and mobile data settings.

Fix 10: Use Third-Party Hotspot Apps

There are several popular hotspot apps for Android, including FoxFi, PdaNet, and WiFi Tether Router.
