It doesn't really look like this on my phone but it is quite similar. What does it mean? I put my old sim card in this SG s3 and this sign came up. I went to my settings and looked at my number and it saids 'unknown' even tho i put my sim card in. I am confused. What should i do so that i actually have my phone number in my phone cos i am lost. Thank you 4 the help.
