Coverage with EastESIM will generally be strong at popular tourist sites like the more accessible sections of the Great Wall of China (e.g., Badaling, Mutianyu) and in major cities such as Beijing and Shanghai, where you can expect reliable 4G/LTE. However, as you venture into extremely remote or mountainous national parks and less developed areas, coverage may vary. Our eSIM connects to top local carriers like China Mobile and China Unicom, maximizing your chances of a signal. For truly off-grid adventures, downloading offline maps and content is always a wise precaution.
