Hi 👋 The dual-band hotspot on the S25 Ultra should let you switch between 2.4 GHz and 5 GHz (sometimes even 6 GHz depending on region). If it’s not working, try these steps:
1. Check hotspot settings – Go to Settings > Connections > Mobile Hotspot & Tethering > Mobile Hotspot > Configure and make sure the band is set to 5 GHz/6 GHz instead of “Auto.”
2. Reset network settings – Sometimes old Wi-Fi configs block the higher band. Go to Settings > General Management > Reset > Reset network settings.
3. Restart once after changing the settings, the band switch usually takes effect after a reboot.
4. If it still doesn’t work, make sure your device is updated to the latest firmware. Samsung often pushes fixes for hotspot issues in maintenance updates.
5. Also note, some carriers or regions limit dual-band hotspot availability, so it can vary depending on your SIM/CSC.
If none of this helps, I’d suggest reporting it through the Samsung Members > Error reports section so the dev team can patch it in One UI updates.
Hi 👋 Thanks for getting back. I understand it’s frustrating when the system still doesn’t work as expected. Since you’ve already tried the steps, it might be a deeper compatibility or software issue.
At this point, I’d recommend raising an Error Report in the Samsung Members app right after you face the issue. That way, the system will automatically attach the necessary logs for the engineers to review. This usually helps Samsung push a quicker fix in updates.
In the meantime, if you urgently need the hotspot on 5 GHz/6 GHz, you could also try inserting a different SIM (if available) just to confirm whether it’s a carrier/region restriction or purely a device bug.
Hi 👋 Thanks for testing with alternative SIMs, that helps narrow it down. Since the same issue persists, it’s likely a device-side software/compatibility bug rather than a network limitation.
I’d strongly recommend sending an Error Report through the Samsung Members app right after reproducing the issue. That way, the system logs get attached for the engineers, and they can analyze it directly.
In the meantime, you could also try resetting the network settings (Settings > General management > Reset > Reset network settings) to rule out any misconfigurations.
Hopefully, this gets picked up quickly in upcoming updates.
