There is a small risk
This subscription comes from Google’s official 18-month AI Pro promotion with Jio in India, so the underlying promotion is legitimate. However, this method of getting access has not been shown to be authorised by Google or Jio.
Jio’s terms say the promotion is for eligible Jio subscribers and is non-transferable. Under those terms, someone who is not an eligible Jio subscriber should not ordinarily be able to claim the offer.
Oga’s vendors nevertheless provide activation links to buyers like you. They say they have fulfilled Jio’s requirements, but they have not explained how (for trade-secret reasons).
Oga therefore cannot independently verify their method or guarantee that Google or Jio will honour a resold activation for the full 18 months.
Oga’s view is that even if access lasts for only part of the 18 months, the value may still outweigh the ₦20,000 cost.
But if you require guaranteed 18-month access, it is best to skip this deal.
