Phones that can access the internet are very inexpensive now -compared to a house. The woman in the radio programme said she had a basic phone. A bit like those black iron alms bowls during the Gotama Buddha’s time, I suppose!
Gender is not important. Its natural to feel compassion when someone is in trouble, and potential danger as is that case with homelessness. Sexual attacks are very common if you are homeless and a woman, AFAIK.
