Recently, my Nexus 6p has been losing signal and then it comes back... sometimes. I'm not sure if it's a problem with my phone or what, but my carrier says I should have excellent signal, where I live. When the signal goes away, it shows an X beside the triangle that usually has bars in it, but in this case it has no bars. Also, it says "Emergency Calls Only". I tried restarting my Nexus 6p, and the signal came back but after a few minutes it was gone. I don't want to continuesly be restarting my phone, so please help me out. Thank you. btw I'm not sure, but my sim card may be broken because when I popped it out of the sim card it bent a tiny bit and I heard some crunching. But it's weird cause I can call and text but my data is having the problem I stated above. I have not dropped it and re-seating my sim didn't do anything. but thank you.
