Can I only answer the phone in China?

No, worry-free cards can also make calls.

In China, you can not only answer the phone and text messages, but also make phone calls. You just need to download the "sim Little 2" application in the appstore, register your account, and click Activate on the "Me" page.

After activation, enter the product activation code, and then dial the number starting with 800, and you will receive the prompt of successful activation. The activation tutorial of worry-free dialing function is available online.
