Do I benefit switching from Magenta to Go5G Plus/Magenta Max? https://imgur.com/a/vPhZQo7
Will all my promotion lines/Line on us, insider code carry over to Go5G Plus? I'm hoping for a good trade-in deal coming up soon as Iphone 15 is launching 09/12 and hope that I could upgrade from current Iphone 8 to Iphone 15.
