What call can I make with Unicom mobile phone card (SMS is also ok) and I can directly recharge Q coins?

To use Unicom's mobile phone bill to recharge Q coins, you need to log in to Tencent Recharge Center for operation. In the top-up interface, select "More Ways"-"Mobile Phone"-"Unicom", and follow the prompts on the page to call the corresponding province. Tips: At present, only some provinces support this service.
