Public Wi-Fi at Stations, Malls and Cafes: What Is Safe and What Is Not
6 min read Free Wi-Fi is handy when mobile data is slow, but a shared network is not a private one. Learn which tasks are fine, which should wait, and how to spot a fake hotspot. September 27, 2026 08:28 By Disha Varia, Guj Times
You are waiting at a station, your data pack is nearly finished, and a free Wi-Fi network appears. It is tempting to connect and carry on as usual. Public Wi-Fi is not automatically dangerous, but it is a shared space, and treating it like your home network is where people get into trouble.
Why public Wi-Fi carries extra risk
On your home network, only you and your family connect. On a public network, anyone can join, including people who want to watch traffic or set up a copy of the network with a similar name. Many websites now use encryption, which protects a lot, but not every app and not every site does, and a fake hotspot can still trick you into entering details on a look-alike page.
A note on OTP login pages
Some public networks ask for your mobile number and send an OTP before you can browse. That step is a registration process; it does not mean the connection is private or secure.
Fine to do on public Wi-Fi
- Reading news or articles.
- Looking up directions or timetables.
- Streaming a video you are not signed in to.
Better to avoid
- Net banking, UPI payments and card payments.
- Logging in to email or social accounts that matter, unless you use two-step verification.
- Entering Aadhaar, PAN or other ID numbers.
- Downloading apps or files from pop-ups.
How to spot a fake hotspot
- Ask the staff for the exact network name. Scammers copy the name and add a small change, such as an extra word or a different spelling.
- Be suspicious of open networks that ask you to install an app or certificate to connect.
- If a login page looks different from the usual one, or a payment page appears unexpectedly, disconnect.
Simple settings that help
- Turn off "auto-connect to open networks" in your Wi-Fi settings.
- When you finish, tap the network name and choose "Forget".
- Turn off file sharing and Bluetooth visibility when you are out.
- Keep your phone updated, as updates fix known weaknesses.
What about a VPN?
A VPN encrypts traffic between your phone and the VPN company, which adds a layer of protection on shared networks. It is not a magic shield, because you are placing trust in the VPN provider, and free services vary in quality. Read our overviews of TunnelBear and NordVPN to understand the trade-offs before you choose.
The safest habit
For anything involving money or passwords, use your own mobile data or your own hotspot. It costs a little data, but it removes the risk of an unknown network. If you must do something important on public Wi-Fi, switch to mobile data for that task only.
Quick answers
Does the padlock in the address bar make it safe? It shows that the connection to that site is encrypted, not that the site itself is trustworthy.
Is hotel Wi-Fi safer? A password-protected network is better than an open one, but it is still shared with other guests.
A short routine before you connect
Ask the staff for the exact network name. Connect only to that one. Turn off automatic connection to open networks. After you finish, forget the network in your Wi-Fi settings so your phone does not rejoin it later without asking.
Mobile data is often the safer choice
For anything involving money, such as banking or shopping, switch to your mobile data instead of public Wi-Fi if you can. It may use some data but removes a risk. If you must use Wi-Fi, check that you are on the right site and that the page does not behave oddly.
Do not let strangers use your phone as a hotspot
If someone asks to use your hotspot or phone for a quick call, be careful. Strangers can see what you open on an unlocked phone. Offer to make the call yourself and hand over only the speaker.
