Right now I can make calls and text without the SIM which I couldn't do with my LG Lucid on PagePlus (a 4G phone). I don't know if I went the hard way with flashing my Lucid to PagePlus by keeping the SIM installed, or if it's just the different phone.
For those that use PagePlus on your S3, do you have the SIM installed?
If it's the case that no one else has an S3 on PP without a SIM< I could make instructions on how to flash the S3 with the SIM.
Edit: I could be very noob by writing this, but oh well I'm curious.
