Some carriers (such as Sprint) are shipping the Galaxy Note 9 with hotspot disabled. This means you cannot enable wireless hotspot or USB tethering. Usually these carriers offer hotspot as an additional add-on to your monthly service.
It’s a bit ridiculous paying a carrier for a basic device feature, so in this guide, we will show you how to manually enable Android hotspot through ADB commands.
- ADB & Fastboot (see Appuals guide How to Install ADB on Windows)
Enable Developer Options on your Galaxy Note 9. Go to Settings > About Phone > tap Build Number 7 times.
Go to Settings > Developer Options > enable USB Debugging.
Connect your Galaxy Note 9 to your PC via USB.
Launch an ADB terminal on your PC (hold Shift + right click in your main ADB folder and choose ‘Open a Command Window Here’).
Now run the following commands:
Settings put global tether_dun_required 0
settings put global tether_dun_apn
Now turn off mobile data, turn on hotspot, and turn on mobile data.
Every time you want to use mobile hotspot, you must turn mobile data off first, enable hotspot, then re-enable mobile data.
When you want to disconnect your mobile hotspot, you must turn hotspot off, then disable and re-enable mobile data.
