Sending text messages on Android phones will be delayed for a day or two. What is the reason and how to solve it?

In this case, if it's not the mobile phone or the mobile phone card, the first step is to give the mobile operator a solution, and he will adjust it for you, so that you can determine whether it's the collection problem or the mobile phone card problem. If it is a mobile phone card problem, customer service will naturally help you solve it. If it's a mobile phone problem, you'd better go to customer service and ask the technician to help you adjust it! ! !

I hope your mobile phone will get better soon! ! ! !
