I have spent a whole week of missing. Were missed about a $1000. Due to xfinity mobile not being able to activate a physical sim or a physical sim. They said it was a phone issue. I ordered a new phone. I'm in the store been in the store for 4 days and have a new phone and still they saying a new issue now. They saying that the number is active when  they click It is showing in active. They're saying they are talking to the tier 3 department. But now the new issue, they're saying they can't.  Do.
