{"product_id":"east-asia-esim","title":"East Asia eSIM - Japan, South Korea \u0026 China","description":"\u003cp\u003eAn East Asia eSIM keeps you online across Japan, South Korea and China on a single plan, ideal for a multi-country trip through the region. Set it up before you go, because eSIM providers' own sites can be unreachable from inside mainland China, then switch it on when you arrive.\u003c\/p\u003e\n\u003ch3\u003eExcellent coverage, and a note on China\u003c\/h3\u003e\n\u003cp\u003eCoverage is generally strong across the major cities of Japan and South Korea, on their metros and high-speed trains, and across the main Chinese cities, so a trip taking in all three is easy on one plan. Japan and South Korea have an open internet, but mainland China filters it, so apps like Google and WhatsApp are blocked on a local Chinese connection. Whether they work in China depends on how the plan routes its data: some internationally routed travel eSIMs can provide access to services that are otherwise filtered on mainland connections, but this should not be assumed for every plan, so check the plan details.\u003c\/p\u003e\n\u003ch3\u003eHow much data\u003c\/h3\u003e\n\u003cp\u003eA week or two of maps, translation and messaging across the three is often around 5-10GB for a week and 10-20GB for two, with more for heavier use. A data-only eSIM does not provide a phone number for receiving ordinary SMS on that eSIM, so keep access to a separate number if you need verification texts for services such as WeChat Pay or Alipay. These are starting points, and actual use varies.\u003c\/p\u003e","brand":"Astaroam","offers":[{"title":"China mainland \u0026 Japan \u0026 South Korea 1GB 7Days","offer_id":56210747687289,"sku":"CNJPKR-3_1_7","price":2.35,"currency_code":"GBP","in_stock":true},{"title":"China mainland \u0026 Japan \u0026 South Korea 3GB 15Days","offer_id":56210747720057,"sku":"CNJPKR-3_3_15","price":4.71,"currency_code":"GBP","in_stock":true},{"title":"China mainland \u0026 Japan \u0026 South Korea 3GB 30Days","offer_id":56210747752825,"sku":"CNJPKR-3_3_30","price":5.34,"currency_code":"GBP","in_stock":true},{"title":"China mainland \u0026 Japan \u0026 South Korea 5GB 30Days","offer_id":56210747785593,"sku":"CNJPKR-3_5_30","price":7.5,"currency_code":"GBP","in_stock":true},{"title":"China mainland \u0026 Japan \u0026 South Korea 10GB 30Days","offer_id":56210747818361,"sku":"CNJPKR-3_10_30","price":11.89,"currency_code":"GBP","in_stock":true},{"title":"China mainland \u0026 Japan \u0026 South Korea 20GB 30Days","offer_id":56210747851129,"sku":"CNJPKR-3_20_30","price":19.07,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0952\/9370\/2521\/files\/flags_2Fregion_2Fasia_897d4d88-2107-401b-97bb-740dc3734669.png?v=1763305021","url":"https:\/\/astaroam.com\/products\/east-asia-esim","provider":"Astaroam","version":"1.0","type":"link"}
