Supporters should text the keyword of the organisation they wish to donate to, along with the numerical value for the amount they wish to donate. For example, if an organisation's Text Giving keyword is 'water', a supporter wishing to donate £20 to the cause would text 'water 20' to 70085.

Donr allows supporters to donate every whole amount ranging from the value of £1 up to £20 (inclusive).

The keyword must be spelt correctly and the value of the donation must be given in numerical digits, rather than spelled out with letters.

The text will cost the supporter the value of the donation plus one standard rate message.
