Hey. I'm sure I'm not alone on this. I have 4 lines and 2 are eligible for upgrade. I am using 1 of them for the 1 line that is not eligible... What did you guys do once you got the phone delivered? If you plug it up and activate, it'll deactivate the previous sim card. I can't do that since the line I'm using will be in another state Can you just call AT&T and do the whole swap thing without deactivating the previous sim card? Any other advices around this? Thanks!
