Pretty Insane: 50% Off Samsung Phones + 7% Cashback; Samsung Phone Serial Number Required

Update: seems like the codes have run out! Remember to subscribe to the Telegram so you will receive timely updates of such great deals!

I may have missed covering the error fare, but this is a very attractive promo that I got wind of: get 50% off Samsung phones from!

The catch? You have to have an existing Samsung phone’s serial number, call in to Samsung’s hotline to get a unique promo code which you can use on Samsung’s website.

I don’t normally cover non-finance deals, but when it is of such great value, it’s hard to pass.

Moreover, I even managed to get 7% cashback from ShopBack:

S$656 for a 256GB Galaxy Flip 4

Ask anyone – I’m an Apple person, but when you’re selling a flagship smartphone for half its price, I’ll get it:

The code also works for S23 Ultra and Galaxy Fold 4, but the latter which was my first choice is unfortunately sold out. It also only seems to work for models of capacity 512GB and under.

After my ShopBack discount of S$49.42, my phone is effectively S$656.58 and I still get all the miles from the credit card I used 🥲

Cards to use

Speaking of credit cards, Samsung’s MCC is 5732, so you can use cards like OCBC Titanium Rewards, HSBC Revolution, or UOB Preferred Platinum Visa for 4 miles per dollar. As an online purchase, DBS Woman’s World Mastercard and Citi Rewards works too.

For cashback, Citi SMRT’s 5% can’t hurt. UOB EVOL would work, but the amounts are going to exceed its sublimit. Consider using cards like HSBC Advance or even one of the mile cards above and trade the points for cash rebates if you are insistent on cashback.

Here are the steps

  1. Prepare a Samsung handphone’s serial and IMEI number
  2. Call Samsung’s hotline: 1800 425 2997 and select option 8 (Herman from the group has shared that you can dial 1800 726 7864 or use their online chat)
  3. Speak to the customer service officer and request the secret discount code required to purchase phones on
  4. The code will be delivered to you via SMS (in my experience it took a few minutes)
  5. Use ShopBack or sign up for Shopback with CsgtbD to get S$5 + 7% cashback on your Samsung phone purchase.
  6. After that, go to → search for Samsung → click through and complete your order (remember to apply promo code!)

This offer is meant to be until 27th April 2023, but given how much a good deal this seems to be, I’m not confident it’ll last this long. Stocks for the Fold have already evaporated.
