Method 1: Turn Mobile Hotspot off and back on

A simple refresh often reloads tethering services after an update.

1. Open Settings > Connections > Mobile Hotspot and Tethering.
2. Turn Mobile Hotspot off for 15 seconds.
3. Turn it back on and try connecting again.

Method 2: Confirm mobile data works first

Hotspot cannot share a connection that is already broken on the phone itself.

1. Turn Wi-Fi off on the Galaxy S25.
2. Open a website or run a speed test over mobile data.
3. If mobile data is not working, fix that issue first.

Method 3: Check hotspot name, password, and band

An update can reset hotspot settings or force a band that some devices cannot use.

1. Open the hotspot settings page.
2. Set a simple hotspot name and password.
3. Switch between 2.4GHz and 5GHz if the option is available.

Method 4: Restart the phone and the device trying to connect

Both devices may be holding onto an old network session.

1. Restart the Galaxy S25.
2. Restart the laptop, tablet, or other phone using the hotspot.
3. Try pairing again from scratch.

Method 5: Reset network settings

This clears broken wireless and carrier settings without deleting personal files.

1. Go to Settings > General management > Reset.
2. Tap Reset network settings.
3. Re-enable hotspot and test again.

Method 6: Check carrier limits on hotspot use

Some plans disable tethering or temporarily block it after a billing or provisioning change.

1. Open your carrier account app or website.
2. Confirm hotspot data is included in your plan.
3. Ask the carrier to reprovision tethering if needed.

Method 7: Install the latest Samsung or carrier update

A follow-up patch may already fix a tethering issue introduced by the first update.

1. Open Settings > Software update.
2. Tap Download and install.
3. Install any newer build and test again.
