I have an Indian colleague whose dad was in some kind of coma for few months after an accident. He had a real crazy time keeping the house running. His dad's number was attached to all kinds of bills - electricity, gas, milk, water, internet, cable, newspapers etc. Most of the services would send a verification sms to his dad's phone for any kind of interaction. No one knew the password. And it turned into a major nightmare. It wasn't just a question of paying the bills. Lot of these services had to be shutdown or have settings changed temporarily. And each one had a different set of documents/processes required to prove he was a relative.
