Is there a charge for Unicom's secondary card? What's the role?

The monthly function fee of the supplementary card is 10 yuan, and the caller ID fee is free, so you can enjoy the traffic and other free traffic in the main product package, and other fees are charged according to the standard tariff.

Sub-card function: a new service specially developed for Unicom users to make full use of the data traffic in the package. "Take Unicom iPhone4 users with a monthly fee of 286 yuan as an example. The monthly data flow in the package is1g. If you use it alone on the iPhone4, it may not be used up every month. Now that the secondary card has been introduced, the traffic that the mobile phone can't use can be used on terminals such as notebooks and iPad, so that the user's package fee will not be wasted. "
