4G Plan question

[farmman]

Hi everyone. I was just curious to know how this would work. My sister is finally upgrading her line to a smartphone. She ordered the MAXX so she would get double the data for the same $30 price. But ultimately, she actually wants my old droid incredible 2 as her new phone and I am getting this one. My question is, when the maxx is activated on her line and the 4gb of data is set up, will she get to keep the 4gb data when I transfer the htc inc 2 back to that line or will it revert back to a 2gb data plan?
Thank you

Should be able to keep the 4gb regardless imo

I think double data is only for 4g phones, currently.

No, it will go back to 2GB. I did the same thing, ordered a MAXX on a new line and got 4GB then switched that line to a Incredible 2 and it made me choose a new data package and 2GB at $30 was the only choice. Has to be a 4G phone.
