The Institute of Fundraising has launched a campaign calling on the mobile phone companies Orange and T-Mobile to pass 100 per cent of donations made by text message on to all charities.
Bruce Leeke, acting chief executive of the institute, sent out a letter yesterday to its organisational members, calling on them to join the campaign by lobbying the operators.
The letter says that O2, Vodafone, and Virgin have committed to passing on 100 per cent of text donations to all charities. But Everything Everywhere – an umbrella company formed by Orange and T-Mobile to run both networks – is the only remaining operator not to do so.
The IoF says that Everything Everywhere passes 100 per cent of text donations to a small group of charities that are its own charity partners, but this figure drops to 90 per cent of donations for other UK charities.
"We consider this to be an impediment to effective fundraising via mobile text giving, and the institute is now campaigning for Everything Everywhere to change its policy and to end these charges," the letter says.
It adds that the IoF has written to the government to ask it to "exert its influence in this regard".
A spokeswoman for T-Mobile said: "We're aware of the fundraising potential of text donations and we know from our support of big charity campaigns, like Comic Relief and BBC Children in Need, that text donations are a brilliant way to engage with customers, while raising significant funds that can make a real difference.
"T-Mobile gives 100 per cent of all text donations to certain key partners, including Comic Relief, Sports Relief, BBC Children in Need and the Disasters Emergency Committee," she said.
The company was reviewing its text donation service, called Text to Donate "in order to simplify the procedure and make it easier for charities to use this method", she said. The service was being brought in line with Orange, which passes 90 per cent of text message donations to charity.
