But how can people text me?
if it is an Iphone...they can text via iMessage.

Why would you want anyone texting you?
Connect it to your WiFi and use Skype, Telegram, Signal, etc to communicate with people on those same platforms.
You can use iMessage with fellow people on Apple products.
None of these methods allows you true SMS text messaging without getting a phone number, though.
Google Voice, which I believe is free, would let you SMS US phones and get messages back from people’s cell phones, but you also are given a virtual phone number. It does not support multimedia texts, apparently.
Hope this helps.
They will have to email you
