Step by step
Open Mobile Hotspot
Settings, Connections, Mobile Hotspot and Tethering. Tap the words Mobile Hotspot, not the switch, to see its settings.
Check the name and password
Network name is what the other device must pick, and Password is what it must type, exactly as shown. We blurred ours.
Switch the band
Band decides the Wi-Fi frequency. If a laptop or car cannot see the hotspot, try the other band. Ours was on 2.4 GHz.
See which devices used it
Mobile data shared today lists the devices that used the hotspot and how much data each one took.
Check mobile data and VPN
The hotspot shares your mobile data, so Mobile data must be on in the quick panel. A VPN on the phone can stop shared devices from getting online; turn it off for a test.
Restart both devices
Restart the phone and the device that will join, then switch the hotspot on again.
About this guide
A Galaxy hotspot fails in two ways: other devices cannot find or join it, or they join but get no internet. The first is usually the name, password or band; the second is mobile data, a VPN or your plan.
The screenshots are from a Samsung Galaxy A57 5G with One UI 8.5 and Android 16. Other Galaxy phones on One UI 8 use the same menus; on older One UI versions a few names and positions differ. The hotspot name, password and the device that used it are blurred. We only looked at these screens on our phone and changed nothing.
Good to know
Mobile data itself not working? Samsung Galaxy mobile data not working? 7 fixes.
Some plans block or limit hotspot use. If everything above is right and joined devices still get no internet, ask your carrier.
In short: Mobile data on, VPN off, correct name and password, try the other band, restart both devices, check your plan.
