VPN is the acronym in English for “Virtual Private Network”. As the name implies, it is a mechanism capable of limiting communication between cell phones, computers and other devices that have restricted access to the network in question, simply using the necessary credentials. it is a way of interconnecting different devices over the Internet, providing greater security to data, which is encrypted, and making it difficult for third parties to intercept it.
One of the possible uses of VPN is remote access to corporate networks, widely used for the home office system. This is a cost alternative, as connecting all devices by cables can be much more expensive. TechTudo has now separated five questions and answers about how it works and how to use VPN on mobile phones.
How VPN works on mobile
One of the advantages of using VPN on the cell phone is to ensure the security of your data, for example, when connecting to public Wi-Fi networks, which can expose the cell phone to hackers and malware. In addition, your searches, downloads and uploads are done with greater privacy.
Depending on the region of the planet you are on, some content may be blocked due to geographic restrictions. Users can use the private network for activities like watching Netflix from another country, although the company blocks the use of VPN for Netflix.
How to use VPN on mobile
To use VPN on the Android phone, the user must go to the gear icon, which is in the notification bar. Under “Configure”, touch the “More” option. Search for “VPN” and touch “Add VPN profile”. The user must fill in the requested data, which are obtained from the network access provider in question.
To use VPN on the iPhone (iOS), the configuration is done in “Settings”. Under “General”, look for “VPN” and then tap “Add VPN Configuration”. Select the type of protocol, fill in the requested data and complete the operation.
VPN, remote access and alternatives
VPN is a widely used alternative for remote access during the home office. It allows the user to connect to the corporate network and access platforms restricted to employees. In case the company does not offer this modality, TeamViewer becomes a popular application as a way to use the work computer remotely.
It facilitates data sharing between two devices, and also enables participation in presentations, always over secure connections and protected by password. To make the experience even more personal, the app has a control panel, provides chat history, has video calls and allows the use of profile pictures.
Free VPN: is it dangerous to use?
You have to be very careful when using a free VPN service, because some of them can be a threat to data instead of a security and connectivity solution. At the time of download, some free VPN alternatives may bring malicious software such as trojans, malware and spyware.
In addition, as the connection is not tracked by the provider, data may be stolen and sold by the app itself, in order to be sold to advertising companies and content consumption analysis, for example. Website redirection and broadband diversion are other common malicious features in free VPN.
Free VPN alternatives
Some free VPN services, however, are considered secure and fulfill their role. TechTudo then separated three options.
1. Opera VPN
Opera is a browser that competes with names like Chrome and Firefox. In its new version, there are several additional features, including the integration of Opera VPN, unlimited network, free and without subscription. To enable it, just activate it in Menu> Settings> Privacy> VPN. The desired virtual location can be chosen and the statistics of the data used are shown. Another interesting point is that Opera’s VPN can also be used in private browsing windows.
Cloudflare has Warp, a mobile VPN that provides safer and faster browsing. As it is a mobile VPN, traffic on the Internet is more secure, but the version does not allow tampering with the location where the Internet user is located. The practice avoids circumventing the geographical restrictions mentioned above. The service does not ask for personal information, not even names.
3. Speedtest VPN
Ookla created its free VPN provider for the Speedtest application. The network, like other services, points to a policy not to record its activities on the Internet. It assigns a shareable IP from a range of more than 40,000 addresses to make the user’s identity anonymous. In Speedtest, the lock icon at the bottom of the screen is used to activate and create the VPN profile on your phone.
