However, the biggest disadvantage of public Wi-Fi hotspots is security. Most public networks are not properly secured, making it easier for cybercriminals to intercept your data or access sensitive information. If you are working with confidential documents or accessing personal accounts, public Wi-Fi may not be the safest choice.
To improve your security, always use a Virtual Private Network (VPN) when connecting to public Wi-Fi. Avoid performing sensitive activities such as online banking, shopping, or accessing confidential business information over unsecured networks. Always verify that you are connecting to the official Wi-Fi network provided by the venue, and disable automatic connections to open Wi-Fi networks on your device.
If you are unable to connect to the internet using any of the methods mentioned above, you can also use your mobile operator's roaming service. This is the simplest option—just enable mobile data and roaming on your phone, and you'll be connected.
However, international roaming can be very expensive, especially outside your home network's standard coverage area. Even moderate data usage for maps, social media, or video calls can quickly lead to unexpectedly high charges.
Portable internet solutions such as portable Wi-Fi routers or eSIM can reduce your connectivity costs by up to 95% compared to standard roaming charges, while providing predictable pricing and reliable internet access throughout your trip. For this reason, roaming is best reserved for emergencies or short periods when no other internet connection is available.
