Depending on your carrier (I live in the US so I can only speak to them), Calls, MMS, SMS already work just fine. As far as pictures....the Camera on the OG Pinephone is not great, I would not use it to take serious pictures (or I am bad at taking pictures, which may also be true!). The Pinephone Pro has a much better Camera, but so far, it does not work in software.
