Or you could phone her and ask her if she'd be interested in going to (X) activity with you.

Texting is wimpy, anyone can text, and she knows that you have all the time in the world to say something that might appear to be interesting. If you just call the girl, there is no time for you to bullshit around, and she'll know that whatever you say hasn't been thought over a million times to make it seem perfect. The only excuse I can imagine for not calling is if you literally have no game whatsoever. Phoning someone is infinitely more personal than texting, you can pick out real emotion from a conversation over the phone because you're actually talking to someone. The guy in the video is correct, the woman you're after probably has ten men texting her constantly, be the one who actually phones her and you instantly stand out.

Another point that he tries to make in that video is how you need to make the conversation fun, calling someone is way more interesting than texting, it's a delicate balance that will reward you if done right. Half of the "fun" work is done for you if you can keep a conversation without being awkward. And it makes you look like you have a pair, a good conversation tells her that you're sharp as a tack.

I'm sure that you could still score a date if you're good at texting, but you're turning down a free advantage that is going to give you a leg up on the competition.
