How many short messages is limited to Liaoning Unicom card group at a time? I remember that the mobile phone seems to send a group of text messages at most 50 times. Mine is Unicom card Unicom

This is different from place to place, and the principle of locking the card is different. Generally, the quantity is between 50- 120, and some of them depend on the content. This is very powerful. As long as you send an obvious advertisement, sending more than a dozen will be locked. In short, management is getting stricter and stricter. If there are many short messages, it is recommended to consider a professional platform, such as Haoyu Information Communication, 238, which is still a good platform. Locking the card is not cost-effective.
