I was recently asked how to set up text message giving for a church. Encouraging people to give small amounts of money for specific fundraising projects can be a great way of gaining extra funds. Text message donations is usually a paid for service, however the Just Text Giving service (sponsored by vodaphone) is free. You can easily sign up for the service by following this link. You can even create different text services for different donation amounts.
Here is a short video tutorial which explains how the service works.
Being part of the Just Giving and National Churches Trust partnership scheme saves you the £15 per month Just Giving fee and also allows you to set up text giving as well as having an online donations page. There is an application form here.
The National Fundraising Scheme also offers a free service, and some great advice.
