You receive your bills at the address registered in my yallo under "Contact information". You can change the address there with a few clicks, no matter if you receive you bills by email or by post. Then you will receive the next bill from us at the new address. You can also change your preferred language and email address on this page.
You can also view your bills conveniently online in my yallo. Here you can learn how that works and how you can receive your bills by email in the future.
