Modern smartphones often use dual lens cameras. Standard lens is generally 28mm focal length. Second one is usually telephoto lens (50-60mm), or wide angle lens (10-16mm). Focal lengths are defined on full frame sensor size.
Wide angle lenses are useful for these genres when traveling:
Landscape and mountain photography.
Urban and architectural photography.
Interior and lifestyle photography.
I have been using wide angle lens since 2006. It was Sigma 10-20mm lens on Nikon D80 camera with APSC size sensor.
Earlier i have been using standard lens kit Nikkor 18-70mm in panorama mode, stitching 2-3 pictures together.
Now I use my smartphone LG G5 wide angle lens camera and Fujifilm X100T (my travel camera) with wide angle conversion lens WCL X100.
Here are some examples from my portfolio:
