My phone is a Samsung Galaxy S4 and it's not able to recognize the simcard inside it. I reseated and made sure it was properly inserted into the slot then turned it on. The simcard was still not being detected so I tried another simcard and it did not make a difference. What is wrong with my phone? Is there anything I can do to fix it or should I just take it back to the carrier and make them fix it?

If your phone cannot detect any SIM card, try cleaning the contact pins at the back of your phone: the pins that contact with your SIM card when you insert it. See if this works. If this doesn’t work, try factory resetting your phone. To factory reset, on your phone, go to “Settings”, “Backup & reset”, “Factory data reset” then “Reset phone”.
Before factory resetting your phone, don’t forget to backup your entire phone’s data because factory resetting erases your entire phone.
