When packing your bags for an overseas vacation, guessing how many gigabytes of travel esim data you need is one of the most common dilemmas. Buy too little data, and your connection cuts off while navigating dark streets in an unfamiliar city. Buy too much, and you pay for expensive gigabytes you never end up using.
Mobile data consumption increases dramatically while traveling.
