Buying signals
Authorised Samsung SG retailers (Samsung.com/sg, Challenger, Courts, Harvey Norman, Best Denki) carry local warranty. Parallel imports from Shopee/Lazada sellers typically ship from Hong Kong or Korea with distributor warranty only — usually 6 months, not the full 24 months Samsung Singapore provides.
Samsung does not sell a 128GB S25 SKU in Singapore. The 256GB base is what every authorised retailer lists as the entry-tier. If a merchant shows a sub-floor 'S25' it is either an S25 FE (different phone, different chipset), a parallel-import 128GB grey unit, or a non-GenuiNe S-series (S25 FE, S24 FE, S25 Mini which Samsung does not sell in SG).
Samsung Singapore and the three telcos (Singtel, StarHub, M1) run persistent trade-in promos that knock a meaningful sum off the S25 family if you surrender an eligible phone. Our price table reflects the no-trade-in cash floor; trade-in effective pricing is shown as a per-merger highlight.

The cheapest is the Samsung Galaxy S25 256GB at the authorised SG RRP across Samsung.com/sg, Challenger, Courts, Harvey Norman, and Best Denki. Online marketplaces often show the same floor price after GST, occasionally lower during flash sales. The S25+ 256GB starts at the authorised S25+ RRP and the S25 Ultra 256GB at the authorised S25 Ultra RRP.
No. Samsung does not sell a 128GB S25 in Singapore. The 256GB SKU is the entry storage tier across all SG retailers. If you see a 128GB listing it is either a parallel import (no SG warranty), the older S24, the S25 FE, or a mis-labelled listing.
The S25+ costs more than the base S25 but adds a larger 4,900 mAh battery (versus 4,000 mAh), a 6.7-inch display (versus 6.2-inch), and 45W wired charging (versus 25W). If you keep a phone 3+ years and want it to last a full day in year three, the S25+ is the better buy. If you upgrade yearly, the base S25 is enough.
Authorised SG warranty channels are Samsung.com/sg, Challenger, Courts, Harvey Norman, Best Denki, and the three telcos (Singtel, StarHub, M1) on a contract plan. All other retailers — Shopee, Lazada, Amazon.sg — typically ship parallel-import units with distributor warranty, not the full Samsung Singapore 24-month warranty.
The S25 brings the Snapdragon 8 Elite for Galaxy chipset, 12GB RAM across all storage tiers (the S24 had 8GB on the base 128GB), and Galaxy AI features that depend on-device. If you have an S23 or older the upgrade is meaningful; from an S24 the difference is mostly AI features and longer software support.
