How much data do you need for a trip to Thailand?
A week in Thailand typically uses 3GB to 5GB for maps, messaging, ride-hailing, and social media. Grab runs on data, and having maps for the trains and ferries matters more than in most cities. A 5GB plan removes the mental math; 3GB works if you lean on hotel and cafe Wi-Fi. Thailand plans on dizomo start around a dollar for light use.

Is a travel eSIM secure? What you should know
A travel eSIM is as secure as a physical SIM for your data connection, and it removes the risk of losing or cloning a plastic card while traveling. The security concerns are not the eSIM itself but the same ones you face at home: public Wi-Fi, phishing links, and app permissions. Buy from a provider you can reach, keep your home SIM for two-factor texts, and treat airport Wi-Fi like any public network.

How much data do you need for a week in Japan?
A week in Japan with maps, messaging, and a little social media usually lands between 3GB and 5GB. A 3GB plan covers light use: Google Maps for trains, WhatsApp, and the occasional photo upload. Heavy users who stream or hotspot should take 5GB or more. Japan has free Wi-Fi in many stations and cafes, which stretches a smaller plan further.

Do you need Wi-Fi to install an eSIM?
Yes, you need an internet connection to install an eSIM, but it does not have to be Wi-Fi. Any working connection, including your home mobile data or a friend's hotspot, lets the profile download. The cleanest path is installing over Wi-Fi at home before you fly. Once the eSIM is installed and you connect abroad, it works on its own with no Wi-Fi required.

Is a travel eSIM worth it for a long weekend?
For a long weekend abroad, a travel eSIM is worth it if you will use maps, messaging, or ride-hailing even once. Plans under $5 cover a few days of light use, and the install takes two minutes at home. If you are fine with hotel Wi-Fi and paper maps, you can skip it, but the cost of being offline when you need a taxi is usually higher than the plan price.

eSIM for family travel: one plan or several?
For family travel, the cheapest setup depends on how people use data. If everyone mostly stays together and one person can hotspot, one larger plan works. If people split up, separate small plans cost less than one giant plan and avoid hotspot battery drain. Top-ups stack on the same line, so a shared plan can grow mid-trip without a new install.

Why is international roaming so expensive?
International roaming is expensive because carriers charge each other wholesale rates for access to foreign networks, then add a retail markup on top. A single megabyte abroad can pass through two or three networks before it reaches your phone, and every hop adds a fee. Travel eSIMs avoid most of that chain by buying data wholesale directly from local operators, which is why the same data costs a fraction of roaming prices.

Who should use a travel eSIM?
A travel eSIM is worth it for anyone who needs maps, messaging, or ride-hailing abroad, which covers most travelers. Frequent flyers save the most, families save by sharing one plan, and even a long-weekend traveler can find plans under $5. The people who can skip it are those happy with hotel Wi-Fi and printed maps, or travelers whose home plan already includes free roaming.
