How to stop students hotspotting at school
A phone that’s locked away can still share its internet connection. Here’s how student hotspotting works, why it matters, and the practical ways schools stop it.
What is hotspotting?
Most phones can share their mobile data as a personal hotspot over WiFi, Bluetooth or a cable. A student can switch it on, put the phone away, and then connect a laptop, tablet or a friend’s device to it. Smartwatches can also stay linked to a phone by Bluetooth while the phone is out of sight.
Why it matters
- It gets around school web filtering and monitoring, because the device isn’t on the school network.
- It undermines a phone policy: the phone is “away”, but its connection is still being used.
- It can disrupt assessments if devices connect to the internet when they shouldn’t.
- It’s hard to spot, because nothing looks different in the classroom.
Ways schools stop hotspotting
| Approach | What it does | Limits |
|---|---|---|
| Device management settings | School managed laptops and iPads can be restricted from joining networks other than the school’s | Doesn’t cover personal devices or smartwatches |
| Supervision and rules | Teachers watch for devices connecting to other networks | Relies on spotting it, every lesson |
| Signal blocking pouches | The phone is sealed in a pouch with a Faraday lining, so it can’t send or receive mobile data, WiFi or Bluetooth | Works only while the pouch is properly closed and locked |
| Phone jammers | Not an option. Jammers are illegal to own, supply or use in Australia | Heavy penalties, and they can block emergency calls |
How signal blocking pouches work
A signal blocking pouch has a Faraday lining: a conductive layer that stops radio signals passing through. When the phone is sealed inside, it can’t connect to the mobile network, WiFi or Bluetooth, so it can’t act as a hotspot or pass messages to a smartwatch.
The Signal Blocking versions of PhoneLock Secure and PhoneLock Access work this way. Because calls and messages can’t reach a phone inside the pouch, families should contact students through the school office during the day.
Signal Blocking or Non Signal Blocking?
Choose Signal Blocking where hotspotting, tethering or smartwatch messaging is a problem, often in secondary year levels. Choose Non Signal Blocking if you only need phones secured and out of reach. Both cost the same, and many schools use a mix. See our signal blocking phone pouches.

Questions
Can students hotspot from a phone that’s in a locked pouch?
With a standard pouch, yes: the phone can still share its connection. A Signal Blocking pouch blocks mobile data, WiFi and Bluetooth while it’s sealed, so the phone can’t act as a hotspot.
Can schools use a phone jammer?
No. Mobile phone jammers are illegal to own, supply or use in Australia, and they can block emergency calls.
Do signal blocking pouches stop smartwatches?
They stop the phone inside the pouch connecting to anything, so a smartwatch can’t receive messages through that phone. A smartwatch with its own mobile connection is separate, so schools often ask for these to be in flight mode or put away.
How much do signal blocking pouches cost?
PhoneLock Secure and PhoneLock Access cost the same in Signal Blocking or Non Signal Blocking: one set price whatever the quantity, with no subscription.
