Where can I buy a cellphone that doesn't cost much or a free Obama phone without giving any digits of my social security number?

When I had to call 911 and go to the hospital, the ambulance driver said he needed my social security number to identify me.
My caregiver said in the State we live, everybody is asking for our social security numbers, either the last four, or all of it. It's true too. What can I do? It's like no one can do anything out here without them wanting the last four digits. Darn it!!! 🤨
