@grishka yes. i would assume it's even more common for minors. services need to recognize that not everyone has a phone number.

on the other hand, it's not as bad as you think it is. not every store requires a phone number, not everyone rides a taxi (and i've never heard of one that *requires* a phone number), government services are a crapshoot on whether phones are optional or required. and internet is available either through your family's home connection or through public wifi.
