Asia on one eSIM: what is and is not covered
The plan covers 19 destinations, including Japan, South Korea, Taiwan, Hong Kong, Singapore, China, India, Thailand, Vietnam, Malaysia, Indonesia and the Philippines, as well as Sri Lanka, Bangladesh, Pakistan, Laos, Kazakhstan, Kyrgyzstan and Uzbekistan. Cambodia and the Maldives, for example, are not included.
A regional plan suits a long round trip where you fly between countries, say via Singapore, Thailand and Japan. You do not need to find a local SIM in each, and the connection is ready when you land. It uses local networks in each country. In the biggest cities data is generally fast, but in remote areas and mountains coverage varies.
If China is on your route, find out beforehand which of your apps work there. We cannot promise that Google and many Western services function in China. If China is your main destination, consider the country's own plan. For a single country such as Japan or India, the country's own plan is usually the clearest and often cheaper option.
