Can I use the domestic traffic on mobile phone WeChat to travel to Vietnam?

After leaving the country, the mobile phone can no longer use domestic traffic in the package, but will use international roaming traffic.

From 20 15, 1, 2065438, international roaming traffic roaming to Vietnam will adopt the following new tariff standards:

Unit tariff: 0.0 1 yuan /KB, with 50MB daily traffic capped at Beijing time (it will be automatically suspended after capping, and users will continue to calculate according to the unit tariff after reopening, without tariff capping rules), and the "international, Hong Kong, Macao and Taiwan roaming traffic package discount" in Vietnam will be cancelled.

The international roaming traffic charge of China Unicom roaming to Vietnam is 0.05 yuan /KB, and the international and Taiwan, Hong Kong and Macao data roaming traffic is charged in KB, and the part that is less than 1KB is charged in KB.
