I got the following SMS:
HSBC: Enquiry/Unsubscribe 27488033. From now until 31/12/2020, earn 3.6% RewardCash rebate on overseas spending all year round with your HSBC Visa Signature Card. Online spending can also earn 2.4% rebate. Call 82283188 to register. Rebate on overseas spending can be combined with the Red Hot Rewards of Your Choice offer to reach a total of up to 5.6%.

Is this offer on top of the basic $2.78 / mile for Visa Signature (which I have set to Overseas)? And if yes, what is the earn rate with this promo? I still have no idea how the "rebate" works..
