Hi) Can I have a free subscription for 3 months? It's COVID-19 now and I don't have work)

If you are an individual subscriber and you are having financial issues because of the pandemic, Adobe may waive subscription fees for a couple of months. This is not an official policy and seems to be handled on an individual basis. You will have to talk to customer care directly and work something out with them. You must already be a subscriber; Adobe is not going to give free or reduced-cost access to all its programs to people who are not customers.

Be aware that because of the pandemic, wait times are far longer than usual. Please be patient with the people to whom you speak. Like you, they are feeling a great deal of stress. A little patience and understanding will go a long way to helping you in your particular situation.

No you can't.
