How can mobile users stop using SMS to protect numbers?

If you do business first, you need to deduct the fee. After deducting the cost, the downtime insurance number will also be deducted. It seems to be 5 yuan a month. First, do the downtime guarantee, and deduct the downtime guarantee fee in 5 yuan every month. If you start a business, you will also be charged. Of course, the monthly rent and other expenses will not be deducted during the period of downtime, because you applied for downtime. As for the number of mobile downtime, it can also be handled by SMS. I haven't heard of it, but you can call the mobile customer directly and let the manual desk handle it for you, which saves the trouble of sending text messages. One word is enough. I hope it works for you.
