Basically, it's not like I have to make a script for every single Phone Booth, because all of them share how they work (there's an exception on the script in the part of Mom, because she needs to know where you are calling her from, so that little part makes me need a bit of different scripts for her, but besides that, the rest is a single and giant script that works for any phone booth)
Don't worry, all of the phone boothes will be working then.
And as it was said, you receive a beeper (called "PokéBeeper", too creative, huh?), to make up for the lack of an excuse for receiving calls. So now, instead of calls, you'll receive text messages :D
By the way, the VS.Seeker will not show up starting from the next Beta. With all the new remakes appearing, and using the VS.Seeker as way to substitute the Pokegear, I think I needed something to be different now.
