This is the ultimate guide with everything you need to know before buying a prepaid SIM card in Malaysia in 2026, including where to buy a SIM card, up to date prices, the best 4G/5G network coverage, my recommendation and info about eSIMs for Malaysia.

The best prepaid SIM card for tourists in Malaysia in 2026 is CelcomDigi. For around 39 RM, approximately ~$10 USD, you get 65 GB data, unlimited calls and much better usable data speeds than many cheap unlimited SIM cards in Malaysia that come with a 6 Mbps speed cap.
