Here we are answering this after the 5th, so sorry about that!
Have you been able to get this resolved and figured out?
Yeah, after about 48 hours the line appeared on my account. Everything is in order. Thank you.
I'm sorry we haven't responded to you until now. You should've received your new SIM by now. Is everything set-up properly when you look at My T-Mobile? Chances are the SIM wasn't activated yet which means it wouldn't show-up on My T-Mobile.
