eSIM guides by country
eSIM data plans are sold per country or per region, never per city. Pick the country you are travelling to and we will show which plan is cheapest per GB and which local networks it actually connects to.
-
China eSIM
A China eSIM solves data but not the firewall. Here is what actually works for Google, WhatsApp and Maps and why a VPN still matters.
-
Hong Kong eSIM
Hong Kong has no internet firewall. A cheap eSIM or tourist SIM from the airport gives you fast data for Google Maps and WhatsApp from the moment you land.
-
Japan eSIM
Free public WiFi across Japan is unreliable and slow. Compare eSIM plans from uPhone against renting a pocket WiFi device at Narita or Haneda.
-
Singapore eSIM
Singapore offers eSIMs, 100GB tourist SIM cards from S$12 at Changi, and free public Wi-Fi. The real essential is downloading Grab before you land, because setup requires an SMS code.
-
South Korea eSIM
uPhone is the first South Korea eSIM to check for most data-only travellers, with clear caveats for compatibility, live plan terms and local-number needs.
-
Thailand eSIM
Compare Thailand eSIM options by cost per gigabyte and check AIS versus TrueMove coverage for the Andaman islands before you land.
-
Vietnam eSIM
Compare Vietnam eSIM and local SIM options, and learn why Viettel is the network to choose for Sa Pa, Phong Nha, and the Mekong Delta.
