@lahoof: Boost offers are available to customers who have purchased a Galaxy S21, Galaxy Z Fold3 5G, Galaxy Z Flip3 5G or Galaxy Tab S7 device in UK and Ireland, so sadly the Galaxy Tab S7+ is not included in the promotion.
Then why do Samsung keep pestering me weekly with Boost Offers when it obviously doesnt apply to my Tab S7+. Wasted so much effort trying to get this to work, now I know why. I even spoke to support who assured me it did work and was doing something wrong. What a waste of my time.
