Detailed provider reviews for Singapore

Airalo

Recommended

Airalo's Singapore plan ('Connect Lion') runs on Singtel, which has the most comprehensive 5G in Singapore. For a standalone Singapore stop this is overkill — you'll barely use the data. But the real value is Airalo's Asia regional plan, which covers Singapore + Malaysia + Thailand + Bali + Japan on one profile. If Singapore is one stop on a bigger trip, this is the right choice.

Pros
  • Runs on Singtel — best network for minor differences that barely matter
  • Asia regional plan is the real value for stopover travellers
  • Works from the jetbridge at Changi
  • Hotspot enabled on every tier
  • No queue at Changi SIM kiosks
Cons
  • For Singapore-only trips, 1 GB is more than enough — Airalo's 1 GB is pricier than Saily's
  • Local Singtel tourist SIMs are also easy to buy at Changi
  • No unlimited plan needed for Singapore — Wi-Fi is everywhere
  • Best value is the regional plan, not the Singapore-only one

Yesim

Best price

Yesim's $1.50 / 3-day starter is the right plan for a Singapore stopover — you'll barely use the 1 GB and it costs almost nothing. For Singapore + Malaysia trips, the $7.50 / 5 GB / 14-day plan handles both countries comfortably. Unlimited is unnecessary for Singapore alone.

Saily

Privacy-focused

Saily runs on Singtel with the cheapest 1 GB entry price. For Singapore, coverage differences don't matter — any eSIM will work perfectly everywhere. The built-in ad blocker is modest value because you'll use little cellular data in Singapore anyway. Good cheap pick for stopover travellers.

Drimsim

Backup only

Drimsim's one strong use case for Singapore is as part of a global multi-country trip where you need a single eSIM for many destinations. For a Singapore stop alone, it's expensive and unnecessary — a cheap Yesim 3-day plan does the job for a fraction of the cost.

Pay-as-you-go
~$3.50/GB
No expiry
Balance never expires
Pros
  • Works in 197 countries including all SEA destinations
  • Balance never expires between stopover trips
  • Good fallback for global travellers using Singapore as a hub
  • One eSIM across Singapore + Malaysia + Indonesia
Cons
  • Overpriced for Singapore's low-data requirement
  • No volume discount
  • Not recommended as primary for a Singapore stop
  • Yesim's 3-day plan is a better value for stopovers

How much data do you need in Singapore?

Singapore is the lowest-data destination on this entire site. The country has free public Wi-Fi almost everywhere — the Wireless@SG network covers hawker centres, MRT stations, malls, most cafés, hotels, and tourist attractions. Changi Airport has some of the fastest free Wi-Fi on earth. For a weekend or 3-day Singapore stop, 1 GB is overkill.

Where you'll actually use data: Grab rides between districts (Singapore's MRT is comprehensive but sometimes Grab is faster), Google Maps for first-time navigation, and video calls home. If you're there on a stopover between long-haul flights, a 1 GB plan for a week is more than enough. The only reason to scale up is if you're combining Singapore with Malaysia (Johor Bahru day trip, or onward to KL or Penang) on the same trip.

Our recommendation: 1 GB for a standalone Singapore stop of 3-5 days. 3 GB for Singapore + a Malaysia trip. 5 GB if you're using Singapore as a base for a broader Southeast Asia journey.

Network coverage in Singapore

Singapore has three carriers: Singtel (the largest, formerly state-owned), StarHub, and M1. A fourth operator, Simba (formerly TPG), launched in 2020 and has grown quickly but isn't used by eSIM providers yet. Singapore has possibly the best mobile infrastructure in the world — 5G is live and comprehensive across all three major carriers, MRT tunnels have full cellular, and even the underground Marina Bay area has perfect signal.

There are literally no coverage dead zones in Singapore. The entire country is 732 square kilometres, densely populated, and served by extensive cell infrastructure. Airalo, Saily, and Yesim all route through Singtel in Singapore. Any choice works equally well. The only consideration is price and plan flexibility.

Tips for using an eSIM in Singapore

Singapore has the best free public Wi-Fi in Asia. Wireless@SG is the government-run public Wi-Fi network covering hawker centres, MRT stations, Orchard Road, Sentosa, Gardens by the Bay, Marina Bay Sands, most hotels, and Changi Airport. Registration requires a Singpass or mobile number, but many venues have their own open networks with no registration. Your eSIM use will be minimal.

MRT tunnels have full cellular coverage. Singapore's MRT is one of the few metro systems in Asia with continuous cellular coverage in every tunnel and station, including the deeper Downtown Line. You can stream music, check Maps, and use Grab anywhere on the train. This eliminates one of the main reasons tourists need data in other cities.

Grab is available but often unnecessary. The Singapore MRT reaches virtually every tourist destination faster and cheaper than Grab. Use Grab for late-night returns after MRT closes (around 11:30 PM) or for specific hotels not served directly by MRT. Don't budget data for extensive ride-hailing — you won't use it.

Changi Airport free Wi-Fi is gigabit-fast. If you're on a stopover, you don't need any cellular data while at Changi — the free Wi-Fi is genuinely excellent and covers every terminal, hotel, and transit lounge. Your eSIM only matters when you leave the airport.

Why eSIM is the best choice in Singapore

Singapore is the one country where the eSIM vs local SIM debate barely matters, because public Wi-Fi is so abundant that you'll use minimal cellular data regardless. That said, there's still a small case for eSIM: avoiding the airport SIM kiosk queue at Changi (usually under 10 minutes but still time you could save), and having instant connectivity the moment you step off the Skytrain into the main terminal.

The stronger argument: Singapore is almost always part of a bigger trip. Onward to Malaysia, Bali, Thailand, or as a stopover on a long-haul journey. A regional Asia plan covers everything on one profile.

Frequently asked questions

Probably not much. Singapore has extensive free public Wi-Fi — Wireless@SG covers hawker centres, MRT stations, malls, most tourist attractions, and Changi Airport. Most hotels and cafés have fast free Wi-Fi. The only data you'll really need is for Grab rides (if you use them) and first-time navigation between locations. A 1 GB plan is plenty for a 3-5 day Singapore stop.
Yes. All Singapore MRT lines (including the deeper Downtown Line and Thomson-East Coast Line) have continuous cellular coverage throughout tunnels and stations on all three major carriers. You can stream music, check Maps, and use Grab anywhere on the train. This is unusual for Asian metros and one reason your data needs in Singapore are so low.
If your trip includes both Singapore and Malaysia (common via Johor Bahru day trip or onward flight to KL or Penang), a regional Asia plan or a single eSIM covering both countries makes more sense than two separate plans. Airalo's Asia regional plan covers both. Drimsim covers both. For a Singapore-only stop, a cheap Singapore-specific plan is fine.
Yes, comprehensively. All three major Singapore carriers (Singtel, StarHub, M1) have extensive 5G coverage across the entire country. Changi Airport, Marina Bay, Sentosa, the CBD, and residential areas are all 5G-covered. All four eSIM providers on this page connect to 5G automatically in Singapore.
A Singapore-only plan will not work in Malaysia across the Johor causeway — you'd be roaming and either blocked or charged. If you're doing a Johor Bahru day trip (very common from Singapore), either buy a regional Asia plan that covers both countries or plan to use hotel/mall Wi-Fi in JB.
