Re: [Instruction]How to Keep Unlimited Data on Verizon
how does the dumb phone's SIM play any role in this?
There is no SIM on any dumb phone. You mean how the ESN/IMEI/MEID (all phones have those numbers) plays into this, so I'll answer that.
The dumb phone has to have a clean ESN. If it doesn't than you can can't add that phone on the line. Simple as that. In short, the phone has to work on Verizon and not have a Bad ESN in order for the "schema" [sic], or rather scheme to work. I wrote two posts on this subject that were numbered so you can go back a couple of posts and read that again now that this is a little clearer. In fact, I'll briefly go over this when I answer your next question.
Does it just stay in the dumb phone and is reactivated once the new the new phone SIM is activated on the unlimited line?
So, basically, what we are doing is having a dumb phone on a basic line. Only thing we pay for is $9.99 a month for one basic line, plus BS fees and taxes. (No text, no nothing, just a dumb phone ) So then what we do is upgrade the basic phone and make sure the upgraded phone (e.g a N3) is active on the dumb line. Once it is confirmed that it is, turn off the N3 and contact VZW (in my case this was done in one-fell swoop, but I would not do that again...) and you tell them you want to put your original phone back on the basic line, and remove the data plan, etc. Once your dumb phone line is active, you do a device swap with what's on your unlimited line with the N3 (that can be as simple as swapping SIMs or reprogramming the SIM card in the N3.) Once that's done two things happen: 1) Your unlimited data line has the N3 and all is good. 2) Your basic line is now under contract for 2 years ($240 + 300 = cheaper than device payment plan.)
And also, can this process be completed in a day?
Yes it can and yes it does. Mine took an unnecessarily long time, but this was because I dealt with Best Buy (never, ever again...)
I know this sounds complicated (I was just gonna stick with device payment plan, myself.) I myself thought this was a lot of work until I actually took the time to read it, study it and then I was ready to implement it (which was yesterday.) I didn't care that Black Friday is almost here, or that I could have gotten the N3 cheaper if I waited; I wanted that phone now!!
