Does it mean anything if she doesn't text first, when you regularly see her twice a week?

A lady I'm interested in almost never texts me unless she needs something, but there are two big details:

1. She doesn't have an American phone number, so she can only text me over wifi.

2. I consistently see her at least once per week on Friday, and I usually see her on Wednesday night as well.

I know the standard thinking is that she's not interested if she doesn't text, does that apply when two people see each other so regularly?
