Q: I need help immediately please my phone is just searching for network and says No service what should i do?

Hello Ramyar1996,

Thank you for using Apple Support Communities. 

I see that you have been getting a "no service" message on your iPhone. I apologize that I was unable to get to your question sooner, hopefully it was a temporary issue and has been resolved by now. But, if it hasn't, this article provides some steps to try when you are getting thiat message in the status bar. 

If you can't make or receive calls on your iPhone - Apple Support

Regards,
Jeff D.
