I would say not to give your phone to unofficial persons for repairing. When your charging port was not working, it could mean that it was broken. Local repairing shops have local parts which might not support your phone but in return can damage your phone as well. If your phone is not recognising the SIM then man... I'm sorry to say that they have messed up the SIM section.
As per your query, we would request you visit the service shop where your product was previously serviced. They will provide you with all the information in a better way after inspecting the device physically.
