Whether you’re visiting Singapore for a short trip or planning a longer stay, one thing is essential from the moment you land: staying connected. Having access to mobile data means being able to use maps for navigation, order a taxi, update social media, and more with ease. Choosing the right SIM card can make or break that experience. Fortunately, Singapore has one of Southeast Asia’s most competitive mobile networks with affordable plans for both locals and tourists.
Do I Need a SIM Card From Singapore?
As a local in Singapore, a local SIM card is a necessity. For tourists, on the other hand, it might not feel like an obvious choice, but we would recommend it. While it’s possible to rely on Wi-Fi hotspots in malls, hotels, or cafes, they are rarely enough for a modern traveller. A local SIM card can bring plenty of benefits and a smoother experience, thanks to 24/7 access to mobile data.
If you’re into digital entertainment, having a local SIM ensures stable internet speeds, lower latency, and reliable access to international websites and apps that might not be optimised for roaming connections. For example, players who like to gamble online at sites like ReadWrite’s Singapore casino picks can benefit from a local data connection for smoother performance and better security while browsing or playing. A stronger connection would allow you to take advantage of the wide range of banking options and bonuses offered by the best iGaming platforms available in the country.
Other benefits include cheaper or free local calls and texts. At the same time, most Singapore SIM cards also come with IDD minutes, meaning you can make calls back to Malaysia or other countries affordably, which is especially handy if you’re travelling with family or for business.
Which Mobile Operators Can I Choose From?
Singapore has four main network providers (Singtel, StarHub, M1, and SIMBA) as well as a growing number of MVNOs (Mobile Virtual Network Operators) like redONE, Giga!, and Zero1, which lease networks from the major players and offer niche or budget-friendly plans. Coverage across the island is generally great, with fast 4G and rapidly expanding 5G availability.
Here’s a breakdown of the top mobile phone operators in Singapore and what they offer.
1. Singtel
Singtel is Singapore’s largest telco, with the widest coverage and fastest speeds. It’s a go-to option for travellers who want stability and premium service. Singtel’s hi!Tourist SIM cards are popular for visitors, offering up to 120GB of data, free incoming calls, and IDD minutes to Malaysia and other countries.
2. StarHub
StarHub is another major operator known for offering solid network performance and generous data deals at competitive prices. Their Happy Prepaid SIM includes local data (up to 100GB), international minutes, and even unlimited social media usage in some packages. For Malaysians staying a week or more, StarHub’s roaming options also extend into Malaysia, making it a convenient cross-border choice.
3. M1
M1 has gained popularity for offering competitive data pricing without compromising on performance. Their M Card prepaid plans include large data allowances, IDD minutes, and app-based management for top-ups and usage tracking. M1 has also invested heavily in 5G, offering great speeds and stable connections for users who need more from their mobile plan.
4. SIMBA
If you’re looking to save, SIMBA is the cheapest operator on the market. Formerly known as TPG, SIMBA is perfect for budget-conscious travellers who just need large amounts of data at the lowest possible price. Their SIM-only plans start as low as $10, offering up to 100GB of data along with call minutes and SMS. While SIMBA doesn’t yet have full island-wide 5G like the bigger players, its performance in city areas is solid. For light users, students, or digital nomads just checking emails and browsing the web, SIMBA gets the job done without denting your wallet.
5. RedONE and Grid Mobile
Beyond the big players, Singapore also has several MVNOs (Mobile Virtual Network Operators) like RedONE and Grid Mobile, which operate on the infrastructure of the major carriers but offer specialised plans. RedONE, for example, has strong ties with Malaysia and is often favoured by Malaysians living in Singapore for its affordable cross-border call rates and regional packages.
Grid Mobile, on the other hand, caters more to younger users and digital natives, offering data-heavy plans with social media perks, data rollover, and reward systems. These are great options if you’re looking for short-term flexibility or something more tailored to entertainment and content sharing.
Where to Buy SIM Cards in Singapore
Getting connected in Singapore is incredibly easy. All major mobile operators have kiosks or vending machines at Changi Airport, allowing travelers to purchase and activate a SIM before even leaving the terminal. In addition, SIM cards are available at 7-Eleven, Cheers, and official stores located in malls throughout the city.
You’ll need your passport to register your SIM card, as Singaporean law requires this for all prepaid users. Once registered, you’re free to surf, stream, and scroll to your heart’s content.
