iPhone 18 Pro and Pro Max opened for pre-order on 12 September, at AIS and True-dtac 5G at the same time, and went on sale on 18 September, starting at THB 48,900. As is tradition every year, banks and telcos immediately started a pre-order promo race. Here's a summary of what we could verify as of now.

⚠️ Read this first: the credit card promos below are Studio7's general "Apple products" promos (confirmed directly from Studio7's own official promotion signage, instore.studio7thailand.com). They weren't designed specifically for iPhone 18, but you can use them to buy an iPhone 18 just like any other Apple product. Every card comes with a lot of fine print (tiers based on spending, registration required first), so we recommend checking the full details in store once more before you decide. Also, KTC has no straight baht cashback promo like the other banks. It only has a points-redemption promo, "KTC FOREVER", which gives credit back of 13-15% when you redeem points.

At Studio7 (authorised reseller)

SCB Wealth by CardX gives cashback of up to THB 38,000 per person (spend THB 55,000 or more to get the top rate of 3.50%), plus up to 60% more when you redeem points, and 0% instalments for up to 36 months on CardX FLEX/SPEEDY CASH cards only. Promo period is 1 Jul - 30 Sep 2026. This is the highest figure we found this round.

Next come Krungsri/Central The1/HomePro with cashback of up to THB 14,000 (promo period 1 Sep 2026 - 28 Feb 2027), and First Choice with a similar rate. AEON offers both true 0% (Happy Plan/Happy Pay, 6-10 months) and plans with interest of 0.59-0.99% per month for long 36-48 month instalments. The latter is not truly 0%, so don't get them mixed up.

On the KBank side, cashback is up to THB 12,000 per person, plus another 12% when you redeem K Point points (promo period 1 Jul - 30 Sep 2026). UOB gives cashback of up to THB 15,000 plus a GrabFood e-coupon of up to THB 7,500, for a total of up to THB 22,500 per person (same promo period). ttb gives cashback of up to THB 14,400 plus another 10% when you redeem points (promo period 1 Mar - 30 Sep 2026). Bangkok Bank only offers 0% instalments for up to 10 months, with no cashback or freebies.

UOB (the cashback + GrabFood deal totalling THB 22,500 above) took over the entire Citibank Thailand credit card business in Apr 2024. Old Citi cards have all become UOB cards, and there is no separate Citibank Thailand any more. Register for the benefit by SMS: type ISQ3 followed by the last 12 digits of your card number and send it to 4545111.

On the telco side

AIS has launched the "Easy Trade-In, Pay THB 0" campaign, swapping your old phone for a new one the VIP way. AIS customers get up to THB 20,500 off. The pre-order window originally announced was 12-14 September 2026, which has already passed. If you're interested, check the latest conditions at ais.th to see whether it's still available.

True-dtac 5G (dtac merged with True into a single legal entity in 2023, so there is no separate dtac company any more) opened pre-orders at the same time too. Its "Pro Na Lock" campaign takes up to THB 27,700 off when you buy with a package. That maximum is made up of up to THB 7,700 off the phone, up to THB 7,000 for trading in your old phone, up to THB 2,000 continued-usage bonus, up to THB 10,000 off by redeeming True Point/dtac Coin, and another THB 1,000 from ALL Member M-Stamp. You must meet every condition to get the full amount (packages start at THB 1,499 per month). The actual promo period is 18-30 September 2026.

The short version: if you want the best value straight from a telco, True-dtac can take off the most if you meet every condition. AIS has a good deal, but the pre-order window it announced has passed, so check the latest conditions first. On the credit card side at Studio7, if you want the best combined benefits, UOB (cashback + GrabFood totalling THB 22,500) and SCB Wealth by CardX (pure cashback of THB 38,000) are the two highest figures we found. But every promo has spending tiers and different expiry dates, so read the small print in full before you actually swipe your card.
