Iphone 5 activation problem after Reset
Hi.
I am facing trouble with my 'iPhone 5'. It was working absolutely good for last couple of years but suddenly 3 days before the network stopped working. It always shows 'Searching....'. After that I 'Reset the Network Settings' but no improvement. Yesterday I gave 'Factory Reset'. Every thing seemed good but the phone do not active. There is no sim in my phone but still it shows 'Searching...' in the status bar. I also try to active the phone through connect the iTunes. Still the result is same.
One of my friends said the phone lost its imei.
What this means? What should I do now? Is there any replacement/exchange option available?
Please can anyone help me to solve this problem?
iPhone 5, iOS 10.2
