Due to tightening regulations, if you choose a China-specific plan, only overseas debit or credit cards are supported. Domestic cards cannot be used. There are three solutions:
- Use an overseas debit card, such as Ucards or Starryblu.
- Choose a Global plan (which includes China roaming) that supports WeChat Pay, Alipay, and other payment methods.
- Switch to alternative services, such as Youhuibao or KiteSIM.

After purchasing the plan, activate it according to the prompts. The blogger tested the RedteaGO China roaming plan and found that the IP address is from Hong Kong, providing built-in bypass capabilities.
