sorry guys i've spent the past 2 hours reading on here but i just can't seem to understand or have the balls to do some of the stuff incase it doesn't work out so here's my plan, can anyone verify if this will work? i have a family share plan, my line is the ONLY line that has unlimited data, rest of my family did not listen to my advice and upgraded their lines so they all lost their unlimited data. we currently have 5 lines, 4 on smart phones 1 on a dumbphone my line and the dumbphone line are eligible for upgrade my plan is to use the upgrade on the dumbphone and upgrade to a S5 (the phone i want), once it's activated I will then swap that line over back to the dumbphone essentially making the S5 have no line for a few minutes, then i will transfer my line (with the unliited data) to the S5 based on the past 2 HOURS of reading i've done, it seems like it should work right? the dumbphone line will get renewed for another 2 years and then my line will retain the unlimited data. anyone know if this will work?
