Orange will ask its customers to suggest ways in which people could use their mobile phones to help charities.
It will then choose the 10 best ideas and include them on its ‘volunteering app’, which will be launched later this year.
The firm has suggested a number of ways in which mobile volunteering could work.
These include filling in surveys to help charities gather data, taking photos and making videos on a charity’s behalf and providing mentoring and advice to its beneficiaries.
The project is to be launched on Monday. A web page set up by Orange to outline the idea says: "Next time you're waiting at a bus stop, imagine what help people in the queue could give in less than five minutes of their time.
"They could be photo-tagging wildlife, mapping green urban spaces, making an audio map for the blind or filling in a research survey."
An Orange spokeswoman said she was unable to provide any further details on the project until Monday.
