iPhone 5 "Me returned a temporary error"

I'm having a problem with my phone where it drops the carrier for now reason....it gives me a black screen saying "Me returned a temporary error" and then the bars go down...and down...until it says "No service" This happened after I just got a new SIM card from Telus...I told them...and I got my SIM replaced...but the same problem happen....I contacted...Apple Support..but they told me to contact my provider..which I did...and they don't know what the problem is. Some one help? I provided a screenshot. I can't make calls, text...nothing...

 

Just tired that...no luck. Thanks anyways...this really suck though, because now i'm without a phone...I don't wanna go back to blackberry..
