Hello, I have a question about changing my APN to use my Verizon 4G iPad on AT&T's network. Can the profile that is installed using http://unlockit.co.nz/#_Custom be saved if I want to go back to using Verizon? I want to be able to go back and forth. I have unlimited data on my AT&T iPhone and I went thru the $30 4G Verizon plan in only a couple days. I've tried swapping the SIMs and after I installed the APN profile, it worked. I know I might get caught by AT&T, but I figure I'll get a warning before they take away my unlimited data on my iPhone. If I do get a nasty notice from them, I'll stop. But when I went to use Verizon's LTE, it said I was out of data, which wasn't true. When I deleted the APN profile, I was able to connect to Verizon again. So it seems like I have to have an Internet connection first, to download and install the APN profile, before I can swap SIMs, then delete it when I was to switch back. So I'm asking if anyone knows if this can be saved, but not installed. Thanks.
