What card is cost-effective for children's telephone watches?

Children's phone watches can choose to apply for the Internet of Things card, which is more cost-effective than ordinary mobile phone cards.

* Internet of Things cards have no monthly rent and SMS functions, only traffic packages and call duration, and the cost is relatively low.

* The number segment and network element of the Internet of Things card are independent, and the price is cheaper, which is the first choice for many children to communicate.

When selecting an IOT card, it is recommended to consider the following points:

* Choose a reputable operator to ensure the stability and security of the card.

* Choose an IOT card with sufficient capacity to meet the traffic demand of children's telephone watches.

* Choose an Internet of Things card with sufficient talk time to avoid the problem of insufficient talk time when children's phone watches are used.
