Why is my mobile phone sending text messages so slow? Sometimes it takes a minute or two for others to receive it, sometimes it takes four or five minutes, which is too tangled. I used Xiaomi 2s.

For the problem of cell phone signal, you can try to open "SMS Delivery Report" in SMS settings. You send it to the other party. As soon as his mobile phone receives it, there will be a prompt on your side, and the other party has received it. See how long it takes. Generally, in some cases, the signal will get worse after brushing the root. The bad signal is the reason for the baseband of the mobile phone. Download a baseband switching assistant to solve this problem. I hope the landlord will adopt it and give points after answering.
