Practical eSIM tips per country, so you know what to look for before you book.
Japan
Japan has excellent 4G and 5G coverage, but free public wifi is less common than most travelers expect. An eSIM for Japan can be activated before you land at Narita or Kansai, so maps, translation apps and the Suica app work from the moment you arrive.
Thailand
From the buzz of Bangkok to islands like Koh Samui and Phuket, your phone is essential in Thailand for Grab, maps and translations. An eSIM means skipping the physical SIM card queue at Suvarnabhumi Airport.
United States
The US is vast, and coverage varies significantly by carrier and region. For a road trip along, say, the west coast, it matters which network your eSIM runs on outside major cities.
Indonesia (Bali)
Bali is popular with digital nomads and holidaymakers, and even coworking spaces there rely on a solid mobile backup connection. If you island-hop by ferry, an eSIM also beats buying a new local SIM on every island.
Spain
If you're an EU citizen traveling to Spain, your own plan often already works for free thanks to EU roaming. For non-EU travelers, longer stays, or digital nomads in cities like Barcelona or Málaga, a local eSIM is often still cheaper and more flexible.
