DJDamage misread I believe. Err0r has her number, but he's wondering if it's ok for him to text her until she calls.
Honestly, it could go eitherway. If you text her expecting her to eventually call, she won't.
If you wait for her to call, you could be waiting a while.
The only time I ever call a girl is when I expect to meet her sometime soon. I never call unless I want to see her. When i do call, it's a 5 minute max call. Hey how are you, I'm fine, yep, ok, let's meet up this week.
Talking on the phone is for girls.
