Can I just use apps & camera on cell phone?

I am severely “Tech Impaired”, so my question may seem a bit simple, but I would like to know if there is a call/Smart phone that I can take with me to Europe to just use the Apps & Camera, without using any kind of cell phone service. I don’t want to make any calls while I’m there; just use the apps & camera. I don’t need the cellphone service at home, either, as I don’t make many calls and just use Tracfone.
