Going to Hong Kong or Macau too? At checkout you can add a destination. Hong Kong 5GB is $9.90 for 30 days. Macau 5GB is $9.90 for 30 days. Hong Kong 3GB is $7.90. Macau 3GB is $7.90.
This add-on is a separate eSIM with its own install. Your phone keeps two eSIMs and you switch data between them. Each eSIM is charged at its catalogue price.
Every China plan can add a separate Hong Kong or Macau eSIM. Some plans can switch to Greater China instead, for example China 10GB to Greater China 10GB ($18.90, 30 days). Checkout shows the switch when your plan has one. Greater China is a single eSIM for mainland China, Hong Kong, and Macau. It replaces the China plan.
Full refund if not installed, within 30 days of purchase. 24/7 support.
Plans and prices for each destination are on the Hong Kong eSIM, Macau eSIM and Greater China eSIM pages.
