Is the children's phone watch in the calling card or is it only used for emergency calls?

Hello, I'd like to ask whether children's telephone watches should be put in calling cards or only for emergency calls. Children's phone watches are more suitable for emergency calls than calling cards. The reasons why only the emergency call mode is superior to the calling card mode are explained in detail below:

1, which is more secure: in emergency call mode only, children can only dial the preset emergency call number, and cannot make other calls or text messages. This can prevent children from misoperation or being harassed by bad information, and ensure the safety of children.

2, simple and easy to use: only in the emergency call mode, children can dial the emergency number by pressing the emergency call button on the watch, which is very simple and easy to use, avoiding complicated operations and settings.

3. Save money: In the calling card mode, you need to buy a calling card and pay for it. Children may make unnecessary phone calls and send unnecessary text messages, resulting in unnecessary expenses. In the emergency call mode only, there is no need to insert a calling card, which saves the communication cost.

4. More suitable for younger children: For children in kindergartens and lower grades of primary schools, their awareness of self-protection is weak and they are vulnerable to bad information and fraud. In the mode of emergency call only, children can be prevented from receiving bad information and harassing calls to ensure their health and safety.
