Im in the same boat, Text is faster and less obvious than a phone call, but i absolutely see why alot of girls ignore them and i agree with it.
Imagining hearing your phone ring and before you even look at it you no its gonna be aload of shit
I find tho if you see a girl and the appointment goes well, and you wish to see them again they are more likely to answer a text from you because they know you are a truster client who isnt a time waster, if you state who you are in the text of course.
Take it slow, and let the good times roll
