How do you solve the security problem if your phone is dropped?

If your mobile phone is lost, you can borrow a mobile phone as soon as possible to call your own lost mobile phone to see if anyone answers. If you call your lost mobile phone and someone answers, you can Have a good talk with him (the person who picked up the phone) and see if he is willing to return the phone to you, and you will give him some reward. If he is unwilling, I suggest you call the customer service number of your bank and Alipay immediately and explain to them (bank and Alipay) that if your phone is lost, your bank card account and Alipay account must be frozen immediately! Otherwise, it would only take a matter of minutes for someone to hack your phone, and you would suffer heavy losses by then!
