I use the dynamic zone in Bazhou, Xinjiang. Why is there an extra charge for sending text messages to Unicom Telecom? But I have a short message package and I haven't used it up yet. ...

Hello, the SMS package you ordered is a peer-to-peer package, which means that only the SMS sent by the mobile card will be deducted from the package, and other operators, whether Unicom, Netcom or Tietong, will be deducted according to the normal fee. The short message in this package is the so-called short message in the network, and does not support the external network. I hope you can understand and calm down.
