Engineers Today, I want to share an important lesson that every phone repair engineer should think about 
A customer brought in a phone for repair.
The technician did his job professionally and fixed the phone.
Before leaving, the customer asked, "Please check if the network is working. The last technician who repaired my phone disappointed me."
Wanting to help, the technician inserted his own SIM card into the customer's phone to test it.
Everything worked perfectly.
The customer paid and left.
Three days later...
Police officers walked into the technician's shop.
He was shocked.
The phone he had repaired had reportedly become part of an ongoing criminal investigation. During the investigation, the technician's SIM card appeared as one of the most recent SIM cards used in the phone.
Imagine trying to explain that you only inserted your SIM card for a few minutes to test the network.
Whether you're eventually cleared or not, you may still face questioning, stress, legal costs, lost business, and damage to your reputation.
My advice to every mobile phone technician is simple:
Never use your personal SIM card to test a customer's phone.
Ask the customer to provide their own SIM card, or use a dedicated workshop test SIM that is properly managed and used only for diagnostics.
It takes only a few seconds to insert a SIM card, but those few seconds could lead to days, weeks, or even months of explaining yourself if the phone later becomes part of an investigation.
Protect your name.
Protect your business.
Protect your future.
Every experienced technician has one mistake they wish they had never made. Don't let this become yours.
If you're a phone technician, share this post. It might help someone avoid a problem they never saw coming.
