Internet Access in Singapore: SIMs, eSIMs, & Wi-Fi

Singapore is one of the most connected cities in the world. Whether you are navigating step-free MRT stations, finding an accessible café, or booking a last-minute ride across town, staying online is essential. From ultra-fast mobile networks to island-wide public Wi-Fi, getting connected here is simple, reliable, and surprisingly affordable.

For travelers, having internet access means real-time directions, instant translations, ride-hailing apps, food delivery, attraction bookings, and quick access to accessibility information. For locals, it is about staying connected at work, on the move, and when supporting family members or friends with accessibility needs.

This guide is designed to be a practical, no-nonsense resource for anyone visiting or living in Singapore. We will walk you through the main options for staying online, including:

• Physical SIM cards from Singapore’s major telcos
• eSIM plans you can activate before or after arrival
• Pocket WiFi rentals for families and groups
• Free public Wi-Fi is available across the island

SIM card

If you prefer a traditional physical SIM card, Singapore offers some of the most reliable mobile networks in Asia. Coverage is excellent across the entire island, including MRT stations, shopping malls, hospitals, attractions, and most underground spaces. All major telcos support 4G and 5G, and prepaid tourist SIM cards are widely available at Changi Airport, convenience stores, and official telco shops.

A local SIM card is a good option if you:

• Are you staying for more than a few days
• Want stable, high-speed data everywhere
• Need local call and SMS access
• Prefer a plug-and-play solution

Most tourist SIMs come with generous data bundles, local call minutes, and international call options. Registration is required by law, so you will need your passport when purchasing.

eSIM

If you prefer a fully digital solution, eSIM is one of the most convenient ways to stay connected in Singapore. An eSIM lets you activate a mobile data plan without inserting a physical SIM card. You simply scan a QR code, install the profile on your phone, and you are online within minutes.

This option is ideal if you:

• Want to stay connected the moment you land
• Do not want to swap SIM cards
• Are you using a newer smartphone that supports eSIM
• Prefer managing everything digitally

Most modern iPhones, Samsung Galaxy phones, Google Pixel devices, and many flagship Android models support eSIM. Before purchasing, it is always a good idea to check that your device is compatible.

Below are some of the most popular and trusted eSIM providers for Singapore.

Pocket WiFi

Pocket WiFi is a portable router that provides internet access to multiple devices at the same time. It is especially useful for families, tour groups, business travelers, and anyone carrying more than one device, such as a phone, tablet, and laptop.

Instead of buying multiple SIM cards or eSIM plans, you can connect everyone to a single WiFi unit. Most pocket WiFi devices support between 5 and 10 devices simultaneously and offer stable high-speed connections throughout Singapore.

Pocket WiFi is a good option if you:

• Are you travelling as a group or family
• Need to connect several devices at once
• Want to avoid changing SIM cards
• Prefer unlimited or high-capacity data plans

Devices can usually be picked up at Changi Airport or delivered to your hotel, and returned before departure.

WiFi

If you do not want to rely entirely on mobile data, Singapore also offers one of the most extensive public Wi-Fi networks in the world. Free Wi-Fi is widely available in MRT stations, shopping malls, museums, libraries, hospitals, tourist attractions, and public buildings.

For travelers and locals alike, public Wi-Fi is a helpful backup option when your mobile data runs low, or when you are working from a café or spending a long day out exploring.

Below are the main public Wi-Fi options you will encounter across Singapore.

Wireless@SGx

Wireless@SGx is Singapore’s nationwide free public Wi-Fi service. It is available in thousands of locations across the island, including:

• MRT stations and bus interchanges
• Shopping malls
• Public libraries
• Museums and galleries
• Community centres
• Hospitals and clinics
• Government buildings

You will see the “Wireless@SGx” network name when scanning for Wi-Fi in most public places.

How it works

1. Download the Wireless@SGx app on your phone
2. Register using your mobile number (local or international)
3. Configure your device once
4. Connect automatically at any Wireless@SGx hotspot

Once set up, your phone will auto-connect whenever a Wireless@SGx network is available. The app also shows hotspot locations, connection status, and basic diagnostics.

The older Wireless@SG network is being phased out, so make sure you are connecting to Wireless@SGx for better speed and security.

Changi Airport WiFi

Changi Airport offers free Wi-Fi throughout all terminals, including public and transit areas. The network name is #WiFi@Changi.

You can connect by:

• Enter your mobile number to receive a one-time password, or
• Scanning your boarding pass at Wi-Fi kiosks

Coverage is strong across departure halls, arrival areas, Jewel Changi, lounges, and waiting areas. It is ideal for downloading maps, booking transport, and messaging family as soon as you land.

Shopping malls

Most shopping malls in Singapore provide free Wi-Fi for visitors. Major malls such as:

• Jewel Changi
• VivoCity
• ION Orchard
• Ngee Ann City
• Suntec City
• Marina Bay Sands Shoppes

offer mall-wide Wi-Fi networks.

Wi-Fi information is usually displayed near entrances, information counters, or on digital directories. Some malls require a quick registration using your mobile number, while others offer instant access.

If you are unsure, simply ask at the concierge counter. Staff are used to helping visitors get connected.

Cafés, restaurants, and attractions

Many cafés, restaurants, and tourist attractions also provide complimentary Wi-Fi. This is common at:

• Coffee chains
• Hotel cafés
• Food courts
• Museums and galleries
• Co-working spaces

Look for Wi-Fi stickers near the entrance or counter, or ask the staff for the network name and password.

Public Wi-Fi in Singapore is generally fast, stable, and safe for everyday browsing, navigation, and messaging. However, for video calls, large uploads, or constant navigation while moving, a SIM card, eSIM, or pocket WiFi remains the more reliable option.
