What do you mean by sending me a price list?

According to the information you provided, if you didn't handle the business, you received the business information reminder of the tariff change, and received a phone call from the local Unicom to remind you to send 3G traffic. It is not excluded that it is because you promised low consumption traffic. If the commitment of low consumption flow is successful, you need to promise to reduce the consumption amount of your activities every month during the agreement period. If the deduction is insufficient in the current month, the low consumption difference will be deducted in the next month. It is recommended that you contact the local Unicom's manual customer service to assist in verification. The specific situation is subject to local policies.
