Girls, My girlfriend is backpacking and won't contact me nor wants me to contact her, wants back to basic but is still online after day 4. What to do?

We've been together now for 4 months. It's been her life long dream to go backpacking without phone nor internet. She did take her phone with her for emergencies but was going off-line during the trip. She said she won't be contacting me nor wants me to contact her because she wants to re-discover herself and be in contact with nature. But i can still see her online on FB and whatssapp (no stalking but i miss her and re-read some off our convo's) Is this normal behaviour from her?
