I bought my Iphone in Estonia. Can I buy Apple Care?

Settings, General, About

Is there an option to buy it?

It has to be within 60 days of purchase

Or you can reach out to Apple Support directly. You should be able to reach them here

I think not. If there is no Apple in Estonia how did you buy the phone? Was it through a shipping forwarder? If so I don't think you have basic warranty either,

I think you will be out of luck but ask iDeal if they provide after sales support
