invalid name

One day he bought a cell phone, one of those that you need to register online.
When he entered his name, the website said «invalid name». He couldn’t proceed.
After a couple of try outs with his real name he just entered «John Smith».
It worked.
A month later he had trouble with the contract.
He called the phone company call center. They said «You need to put John Smith on the line.»
«We can’t do anything for you.»
He hung up, called back immediately and said:
«Hello I am John Smith»
It worked.
