We now have a new Text Donation system in place. Text the word RETT to 50300 to donate €4 to The Rett Syndrome Association of Ireland. 100% of your donation goes to The Rett Syndrome Association of Ireland across most network operators. Some operators apply VAT which means that a minimum of €3.25 will go to The Rett Syndrome Association of Ireland. Service Provider: LikeCharity. Helpline 0766805278
