Staying connected no matter when and where has become the lifeblood of the selfie generation. It's even more so for travelers who rely on Wi-Fi for last minute changes on their itinerary or simply a quick hello on social media, letting their friends and the whole world know that their flights have safely landed and already checked in to their hotels.

No wonder getting online has become possible even in the world's most unlikely places. Travelers no longer have to be boxed in the four walls of their hotel room or a café that offers free Wi-Fi. The current demand has made it possible to be on the go and still stay online.

You can snap a selfie with the iconic Eiffel Tower or the archaic site of Petra. Even share a real-time video while in the Sydney Opera House or while strolling the gardens of Taj Mahal. That's because these not-to-miss landmarks offer not just sightseeing pleasures but also access to immediate sharing through an outdoor Wi-Fi, according to Lonely Planet.

Sometimes, though, you're just strolling along an ordinary street when you pass by an eye-catching wall mural or a gripping street scene that makes for an interesting Instagram photo or a Facebook post. This is where the old school public telephone booths come in. The classic phone booths in New York, the UK and Australia have been revamped as Wi-Fi hotspots for on-the-go connectivity.

Besides making the world smaller, faster and more connected, Wi-Fi zones can also serve as a safety net, even saving lives. Those who take to the off the beaten tracks would understand.

Take for example the world's highest peak, Mount Everest. As a way of boosting the country's rescue missions for trekkers, the state-run Nepal Telecommunications Authority (NTA) told the Indian newspaper Hindustan Times that they will set up two free Wi-Fi zones along the areas of Lukla-Everest Base Camp and Annapurna Base Camp. This will then automatically make the Mount Everest the highest Wi-Fi spot in the world at 17,600 feet high.
