What card is the cheapest for sending text messages? Who can introduce it? ..

Connect new UP forces, 16 yuan 250, 10 yuan 150 500. It seems to be 28 yuan, and it is not expensive to make a phone call. Busy 2. 4 Idle time 1. 1 long distance plus 179 1 1 roaming fee of 7 minutes per minute is very cost-effective. I'm talking about the market in Shenzhen, which is a little more expensive to visit. For example, Henan's UP card, 18 yuan has 250 short messages, 2.4 yuan is busy, 1. 1, and 50 yuan will be given a long-distance roaming fee every month.
