He has drawn more than 1,000 phrases in the form of cartoon pictures to help people on their travels abroad do things such as buy a cup of coffee or ask where the nearest chemist is.
Customers can use PocketComms to simply point at a picture and get their message across.
James, an artist and for the past 20 years a professional illustrator, thought of the idea while serving as a TA member of 15 (UK) Psychological Operations Group in Afghanistan as the British Army's only combat cartoonist.
He said: "It all started, during one of my many trips abroad, when I was trying to communicate with a group of teenagers in Kabul, Afghanistan.
"I took out my pen and notepad and started drawing. Soon I had a large crowd of curious onlookers asking questions to which I could draw a reply.
"I found that wherever I have travelled around the world I have been able to get an idea across by drawing a picture. It just made sense to me to put a collection of these drawings together so that others could do so too."
