You can only claim if you pre ordered the new Samsung phones, the s21 the s21 plus and s21 ultra, and with the ultra you get buds pro and smart tag, and with the s21 and s21 plus you get buds live and smart tag.
You simply go to Samsung website and put in your order number and your address, and then that's it!
I rang them up and rang them and sent them the right details and then said it still wasn't the right info with the order confirmation and they said that it wasn't anough so I don't know what to do
