you may try but i think you will receive a reply sms saying that it's unsuccessful.

when you sms, you don't have to key in cc number right? so how are they going to link your unregistered phone number with your cc number?

anyway, i still don't think it's so important to swipe 3x on early weekdays. more important is the weekend transaction must be early. unless the cb allocation is finishing and there were many swiped at the same time on that weekend, so they have to use the weekdays 3x transactions to judge. so after you paid and unbar your phone only join is still not too late.

i didn't realise it includes departmental and groceries too! i swiped more than 3x every weekdays and i swiped for groceries on 23/6, 30/5, 6/6 saturday 10am. aiya, rugi lor... should have just registered sms since my grocery category is included. if get is bonus ma. aiyo, how come i thought only dining earlier.

ok la, now want register. what's the code for those who received sms invitation? w4 <space> card number right?

Nope, if you can't spend consistently every month, there's no point on having this card.
For cash back calculations, it is based on posting date of that month.
To avoid any problem, is good that you don't use it on the last 3-5 days each month. The highest record ever for me to get a transaction posted is 9 days   That's when my cash back are not maximum yet.

Does the 10 transactions of RM50 refer to any transactions or limited to the categories selected?

i have not received the luggage yet.. anyone ?

paid TM Unifi bill using Wise at Sam's Groceria @ Nu Sentral.

haven't call CS to confirm MCC but should be under Groceries since reloading TNG there also tagged as Grocery category dy. gonna wait few days to confirm and post the receipt, etc.

you can Unifi, Streamyx, TM phone bills, Astro too. showed them my Unifi ebill on the phone, double-triple checked the account number.

Just to share.

Paid my Unifi and Astro bills at Sam Nu and was recommended to sign up for their membership card.
For the membership card you need to pay RM12 but you'll get RM10 voucher. Each RM spent gets 1 point. 1000 points can redeem RM10 (was told, cannot verify now, so technically 1%). Best part is bill payment is entitled for point collection as well. 

yes, Sam's under Grocery category.

if the aeon receipt/transaction description printed SMKT, then yes under Grocery.
yes.

your tnb account shall receive multiple incoming payment
