Huifu information consultation telephone

Yes, Unicom launched a card last month, 30 yuan 900m (activity only), with an average of 300m per month. The mobile phone card comes with 30 yuan/is a subscription fee. If you spend all the phone calls, you can't give up. Moreover, although you can make a phone call, most people buy traffic. If you buy a card and run out, you lose it. Buy another card. /I wonder if there are similar activities in other places.
