Unicom M-Zone SMS

Depends on how much you pack. I don't remember how many wallets you have. Let me make an analogy. If it's 10 wallet and 200 wallets, then the front 100 wallet is charged, which is 10 yuan. But if you send it to Unicom, you can't send 100, because sending it to Unicom is 1.5. Then there is no charge for the following 200 short messages. Even if you send them to Unicom, if you send more than 200 messages that month, you will start to charge, and the fee is still the same, 1 cent, which is 1.5 cent with Unicom. If you are free, you can check the phone bill at a glance. .
