I charged two g's of traffic, but there has been no text message.

If the Unicom number recharges the traffic, you can log in to the Unicom mobile phone business hall APP, home page-residual traffic, or click menu service-query-residual traffic query to view the residual traffic. If the SMS reminder is not received in time, the SMS reminder will not be delayed. Other operators can also contact the customer service of the corresponding operators to find out.
