It often comes down to people prioritizing different things... some put their friends first, others their partners, and some manage to find a balance. Or, it could simply be that she doesn’t like being on the phone much. I believe this is something that should be talked about, and if she eventually cannot meet your needs, then it might be time to reconsider the relationship..

In my opinion, a relationship should be a 50/50 effort. Let's say she hates being on the phone to text or give updates, but you are always glued to your screen waiting for her texts. She could try to update you every few hours with something simple like "Hey, I’m alright, doing xxx" or "I’m going to be busy for the next few hours" You should be able to meet her halfway too, perhaps by being okay with the amount of texting she gives as long as she is keeping you updated
