This morning I woke up and found that I had signal on my phone. Because before there was a circle with a line through it but when I woke up this morning I found that I had signal and was so happy. So I messaged my friends blabla and I'm on chrome when suddenly my phone freezes and restarts its self. When it restarts there is the circle with the line through it. I tried everything. Taking out the sim and inserting it again. Rebooting. Clearing cache.
