Q: I phone 5 having issues with previously used sim card. problem started recently. After upgrading no results yet

Greetings binuya,

Thanks for using the Apple Support Communities!

From your question, I understand that you are having some SIM related issues with your iPhone. If you are seeing No Service or Searching or the SIM card itself isn’t working any longer, I would suggest reading over and working through the steps outlined in the following article to help resolve this situation. 

If you can't connect to a cellular network or cellular data - Apple Support

Have a great day!
