Iphone6 phone can't receive text messages from strangers.

Hello, I have done the same thing before. I went to the business hall, customer service and professional maintenance point, either I didn't get it or I won't get it. And I can repair my mobile phone by myself, and I need special equipment to recover the information. I can't do it without equipment. The technical appraisal of the public security bureau has this equipment, which is basically not available in other places. Going to the business hall, the data of people is too large to be queried at all. Do you think people will accept going to the public security bureau? It's impossible. And I also know that data recovery requires conditions, not all data can be recovered, and if you still use the data after it is lost, it is very likely that the data you deleted has been overwritten and there is no way to recover it.
