Working - Note 2 Pageplus (flashed 3g) & custom ROM
I had trouble with this and just thought I would throw it out there. I had my Note 2 flashed to pageplus for 3g data while on stock rom. When I rooted and put on custom rom, I could not get data. After searching and searching I did not find anything that helped so I went back to my backup stock.
I got tired of stock (after two days).
I got it working like this. Install rom etc. after first boot do not touch it for 10 min. After 10 reboot and data will work. Then set it up.
It worked for jellybeans, but still wont for CM latest build (maybe it will later).
