Fixing O2 Hotspot on Xiaomi
Before touching hotspot settings: open a browser on your Xiaomi and load a website. If mobile data works on the Xiaomi itself, the problem is with the hotspot configuration, not the O2 connection.
Hotspot shares your mobile data. Go to Settings → SIM cards & mobile networks → Mobile data and confirm it is enabled. Without active mobile data, the hotspot has no internet to share.
Turn Personal Hotspot or Mobile Hotspot off, wait 15 seconds, then turn it back on. Reconnect the device that could not browse.
On the device connecting to the hotspot, forget the network and reconnect from scratch. This clears any incorrect IP assignment.
Some O2 plans limit or block tethering. Log into the O2 app and confirm your plan includes hotspot/tethering. Contact 202 (free from O2) to add it if needed.
Go to Settings → SIM cards & mobile networks → [SIM] → Access Point Names and confirm APN reads: mobile.o2.co.uk. A wrong APN blocks mobile data even if signal shows full bars.
Go to Settings → Connection & sharing → Reset Wi-Fi, mobile networks & Bluetooth. This clears all network config. After resetting, re-enter your hotspot password on connecting devices.
Common Causes of This Issue on O2
| Cause | Likelihood | Fix |
|---|---|---|
| Mobile data off on phone | High | Enable mobile data first |
| Tethering not in plan | Medium | Check plan includes tethering |
| Wrong APN | High | Correct APN settings |
Frequently Asked Questions
Why does my hotspot connect but show no internet?
The most common cause is that mobile data is not working on the Xiaomi itself. The hotspot only shares existing mobile data — it cannot create data if O2 mobile data is not active. Test data on the phone first.
Does O2 allow tethering on all plans?
Most O2 plans include tethering, but some budget plans restrict it. Check your O2 plan details in the app. If tethering is not included, you may need to upgrade or contact 202 (free from O2) to add it.
How many devices can connect to my Xiaomi hotspot?
Most Xiaomi devices support 5–10 simultaneous hotspot connections. Connecting many devices simultaneously divides your O2 mobile data allowance and can slow speeds for all connected devices.
