So you\u2019re on vacation overseas, patiently waiting for your friends to wake up while you sip coffee in the caf\u00e9 across the street. You find yourself staring at your phone, yearning to post on social media, but unsure if you should risk the potentially sketchy wifi or burn through your mobile data plan. <\/p>\n\n\n\n

Sound familiar? If you’re stuck weighing which choice you should rely upon while roaming the world \u2014 mobile data vs wi-fi \u2014 here are a few factors to consider.<\/p>\n\n\n\n

Mobile data vs WiFi<\/h2>\n\n\n\n

Mobile data is essentially the internet you access through your phone carrier. It\u2019s delivered across cell towers and requires your device to have an eSIM or a SIM card. Typically, mobile data works anywhere you have a signal. <\/p>\n\n\n\n

Wi-Fi, on the other hand, is how you can connect your device to the internet through a local wireless network. While travelling, this can come from your hotel, the airport, or the local caf\u00e9\u2019s router. While wi-fi doesn\u2019t require cell towers, it does rely on being physically close to a connection point to work.\u00a0<\/p>\n\n\n\n

The case for WiFi<\/h2>\n\n\n\n

In most cases of mobile data vs wi-fi, the latter tends to be both free to use and easy to find. These days, public wi-fi is generally available in airports, restaurants, hotels, and even some trains. <\/p>\n\n\n\n

It\u2019s perfectly fine to use for large downloads, streaming Netflix, or uploading that 4K drone footage from your latest travel adventure.<\/p>\n\n\n\n

Here\u2019s the catch: unfortunately, public wi-fi isn\u2019t always safe. Hackers seem inclined to seek out unsecured networks, which allow them to snoop on your data, capture login credentials, and even inject malware.<\/p>\n\n\n\n

Additionally, some regions only offer wi-fi that is painfully slow, unreliable, or comes with weird login walls that never work unless you already have a local phone number (looking at you, Europe).<\/p>\n\n\n\n
