Can I use an international eSIM with my Chinese phone?

Yes, most likely. iPhones sold in Mainland China (models XS, 11, 12, 13) support one physical SIM and one eSIM. iPhone 14 and newer models sold there have dual physical SIM slots but no eSIM. However, iPhones purchased in Hong Kong or Macau have full eSIM support. Most recent high-end Android phones from brands like Huawei, Xiaomi, and Oppo sold globally also support eSIM. Always check your specific model's compatibility before purchasing.
