Best eSIM for Singapore

For most travelers, Nomad is the best value eSIM for Singapore, because it runs on Singtel, the country's strongest network, at the lowest per-GB price, and Singapore is so small and well covered that you rarely need more than a few gigabytes. If you want a big, trusted name with easy in-app top-ups, Airalo also runs on Singtel, and heavy streamers or anyone on a longer stay should look at Holafly's unlimited plan. For a multi-country Asia trip, a regional plan from Nomad or Airalo covers Singapore alongside Malaysia and Thailand on one eSIM. Not sure how much data you need? Try the eSIM Finder.

Quick Pick: the Best eSIM for Singapore

Nomad (Singapore 3 GB / 30 days): Runs on Singtel, Singapore's strongest network, at the lowest per-GB price, which is ideal for a city-state where coverage is excellent everywhere and most visitors stay only a few days.

Airalo Singapore Plans

Airalo's Singapore plans connect to Singtel, the country's strongest network, so coverage is excellent everywhere from Marina Bay to the MRT to Sentosa. The Singapore local plan runs at 4G/LTE rather than 5G, but in a city this well covered that still delivers fast, dependable data for maps, ride-hailing, and streaming.

For a short trip or a stopover, the 1GB plan at a few dollars is ideal, since Singapore is compact and free WiFi is everywhere. If you are staying a week or pairing Singapore with the wider region, Airalo's regional Asialink plan covers Singapore alongside Malaysia, Thailand, and other neighbours on one eSIM, which is the better buy for multi-country trips.

Holafly Singapore Plans

Holafly connects to Singtel in Singapore and is 5G ready, so you get the country's best network with unlimited data and no usage tracking. That makes it a strong pick if you stream heavily, work remotely, or simply do not want to think about a data cap during your stay. A fair-use policy applies at very high monthly usage, but typical travelers will never reach it.

For a one or two day stopover, unlimited is usually overkill in a city where a 1GB plan costs only a few dollars, so Holafly makes the most sense on longer visits. Plans run up to 90 days, which suits digital nomads, students, and anyone basing themselves in Singapore for an extended period.

Nomad Singapore Plans

Nomad offers the lowest per-GB pricing for Singapore, with rates starting around a dollar per gigabyte. Because Singapore is small and easy to cover, and because Nomad rides on Singtel with StarHub as a fallback, you get the best network in the country at the lowest price. For most travelers on a short city break, that combination makes Nomad the smart default.

Nomad also offers daily-cap plans for Singapore that give you a generous data allowance each day, which works well if you are unsure how much you will use. Note that these are not truly unlimited; once you hit the daily cap, speeds are reduced for the rest of the day. For a multi-country Asia trip, Nomad's regional plans cover Singapore alongside Malaysia, Thailand, and other neighbours on one eSIM.

Mobile Networks in Singapore

Singapore has three major mobile networks: Singtel, StarHub, and M1. Unlike most destinations, the choice of carrier barely matters here, because Singapore is one of the most densely connected countries on earth and all three networks deliver excellent coverage across the entire island. Whichever provider your eSIM uses, you can expect a strong signal from the airport to the city centre to the offshore islands.

Singtel is the largest network, with roughly 95% nationwide 5G coverage and the only complete 5G rollout across every underground MRT line, plus the fastest measured 5G speeds. Airalo, Holafly, and Nomad all connect to Singtel for their Singapore plans, so your eSIM rides on the country's best network by default. StarHub is a very close second, with over 99% outdoor 5G population coverage and 5G in all underground MRT stations; Nomad can also switch to StarHub for added resilience. M1 is the third operator and also provides strong nationwide coverage. Coverage is genuinely a non-issue in Singapore, so your decision comes down to price, data allowance, and whether you want unlimited.

How to Choose the Right Plan

Singapore is one of the easiest places in the world to pick an eSIM, because every provider runs on an excellent network and coverage is never the deciding factor. Your choice comes down to how long you are staying and how much data you will use:

Frequently Asked Questions

Does an eSIM work on the Singapore MRT, including underground stations?

Yes, and exceptionally well. Singtel and StarHub have rolled out 5G across every underground MRT line and station in Singapore, so a Singtel-based eSIM from Airalo, Holafly, or Nomad keeps a strong signal on platforms, in trains, and in the tunnels between stations. You can stream or navigate the entire ride without dropping out.

Can I use one eSIM for Singapore plus Malaysia or Thailand?

Yes. Airalo and Nomad both sell regional Asia plans that cover Singapore alongside Malaysia, Thailand, and other neighbours on a single eSIM, which is ideal if you are pairing Singapore with a wider Southeast Asia itinerary. If Singapore is your only stop, a local Singapore plan is cheaper per gigabyte.

I only have a short stopover in Singapore. How much data do I need?

For a layover or a day or two in the city, a 1 GB plan is usually plenty for maps, messaging, ride-hailing, and a bit of browsing. Singapore has abundant free WiFi at Changi Airport, malls, and many cafes, so most short-stay visitors never come close to even 1 GB unless they stream video on cellular.

Should I buy an eSIM or a SIM card at Changi Airport?

An eSIM is more convenient for most travelers. You install it before you fly and connect the instant you land at Changi, with no queue and no passport registration at a kiosk. Changi's SIM counters are well stocked but charge tourist prices, so an eSIM usually saves both time and money for a short visit.

Is a local Singapore plan worth it for just one or two days?

Yes, because Singapore eSIMs are cheap. A 1 GB local plan often costs only a few dollars and runs on Singtel, so even for a single day you get fast, reliable data without relying on patchy public WiFi. For a true stopover where you mostly use airport WiFi, you could skip it, but the low price makes a small local plan an easy call.
