Overseas eSIM
An eSIM is a smartphone contract using a SIM integrated into the phone. eSIM allows you to start using communication and call services as early as the same day, even with an online contract.
The following is an easy-to-understand explanation of what an eSIM is and the advantages and cautions of eSIM.
Thailand is cheap and easy to get online in, but the rules changed. Since August 2025, buying a SIM card in Thailand means a passport check and a live facial scan at the counter, and further rules in force since May 2026 require registration in person and cap foreign visitors at three SIMs per operator. That makes the choice between a travel eSIM and a local SIM more consequential than it used to be. This guide compares what Airalo, Holafly, Nomad, Ubigi, Saily and Trifa actually charge for Thailand, using prices read from each provider's own site in August 2026, and sets them against AIS and True tourist SIMs in baht and against carrier roaming at $10 to $12 a day. It also says plainly what we could not confirm, including whether Thailand's registration rules formally apply to foreign-issued travel eSIMs that connect by roaming, so you can see where the guidance is solid and where to check with your provider before you buy.

Getting online in the Philippines is easy. Choosing how is the part that trips people up, because one of the options comes with a legal requirement that most English-language guides never mention. You have four realistic choices: a travel eSIM bought before you fly, a local prepaid SIM or eSIM from Globe, Smart or DITO, international roaming on your existing plan, or a rented pocket Wi-Fi device. Local SIMs are by far the cheapest per gigabyte, but the Philippines SIM Registration Act requires visitors to hand over a passport, proof of a Philippine address and a return ticket, and it caps a tourist-registered SIM at 30 days. This guide covers what that law actually says and where its limits are still unclear, compares the main travel eSIM providers using prices read from their own sites, lists current local carrier plans, and looks at what changes once you leave Manila and Cebu for Boracay, Palawan or Siargao.

Most Taiwan eSIM guides tell you a plan is fast. Almost none show you the numbers. In March 2026 we took a Trifa travel eSIM around Taipei and ran 11 speed tests, 10 on the eSIM and one on a hotel Wi-Fi network for comparison, at the places travelers actually stand: Taipei Main Station, Ximending, Taipei 101, a moving MRT train, Shilin Night Market and a hotel room. The 10 eSIM runs returned a median download speed of 245 Mbps and a mean of 327 Mbps, ranging from 12 Mbps on a moving underground train to 950 Mbps at Shilin Night Market. Nine of the ten were at or above 80 Mbps, and eight showed 5G. Below are the full results with the screenshot from every run, exactly how we measured, the two tests that came back incomplete, and what the numbers mean when you pick a Taiwan eSIM.

Taiwan is one of the easiest countries in Asia to stay connected in, but picking an eSIM is harder than it should be. Providers quote prices in different currencies, some run on the largest local network and some do not, and the rules around Taiwan's real-name registration are described inconsistently across the web. This guide compares six eSIM options for Taiwan using prices pulled from each provider's own site on the same day, in US dollars. It also includes something the other comparisons do not have: first-party speed measurements taken at 10 locations around Taipei on a Chunghwa Telecom connection, with a median download speed of 245 Mbps. You will find a plan-sizing table, an honest comparison against local SIM cards and your home carrier's roaming pass, and a clear account of which identity documents are actually required and which are not.

Setting up an eSIM for South Korea is one of the fastest ways to land in Seoul, Busan, or Jeju with mobile data already running. Buy a plan in an app at home, install the profile on Wi-Fi, and switch the line on the moment your plane touches down at Incheon, Gimpo, or Gimhae. This guide walks through the full five-step setup — compatibility check, app download, plan purchase, profile install, and on-arrival activation — with current pricing in USD, AUD, and GBP, iOS and Android instructions, and the most common troubleshooting fixes when something does not connect. By the end you'll know exactly which phones work, which trifa plan to pick for your trip length, and how to switch the line on without accidentally triggering home-carrier roaming charges.

Tethering functionality is also available with an eSIM. However, when traveling abroad with more than one person, each person should have an eSIM contract. The following is an explanation of the disadvantages of the tethering function that may not be surprising.
