Can I bring a SLR, camera, ipad and mobile phone to Cambodia?

Of course, Cambodian communication infrastructure is aided by China, so mobile phones can roam directly without any adjustment. Of course, there is nothing wrong with the camera. Cambodia is a tourist city. When you come, you are restricted to bring a camera. You think it's in Gao Belle Li. However, it should be noted that Cambodia's customs is the best in the world, and it is very likely (unlikely) to be tipped. You can prepare a small amount of US dollar bills in advance and put them directly in the hands of customs officers, and everything will be OK.
