ok so i have my own plan and my sister has her own seperate plan also. she just added my mom onto hers. i have had mine for a year and would like another phone, so i was wondering if my mom returned the phone they got her, it was some junky free phone, and got the phone i wanted and then we swapped (like give her my old phone and she activates it with her number and i take the new one that she gets and activate it on mine) would i still be able to have insurance on my phone? i hope i worded it right so you guys could understand.
