Singapore
eSIM.Fast 5G data plans. Instant activation, no SIM swap.

The best Singapore eSIM taps into one of the world's best networks, with clear pricing and instant setup. Flysimio runs on Singtel, StarHub, and M1 — offering island-wide 5G from Changi Airport and Marina Bay to Sentosa and the MRT tunnels. Plans are prepaid with no contract and no roaming surprises, so the price you see is what you pay. Your QR code arrives by email seconds after checkout and installs in under a minute, every plan includes free mobile hotspot, and there's a 7-day money-back guarantee. Even for a long layover it pays for itself — land at Changi already connected instead of paying $15–25 a day in roaming.

Getting online in Singapore takes about two minutes. First, confirm your phone supports eSIM — iPhone XS (2018) and newer and most Android flagships from 2020 qualify. Choose your Singapore plan on Flysimio and pay with card, Apple Pay, or Google Pay; your QR code arrives by email within seconds. On Wi-Fi before you fly, open Settings → Cellular → Add eSIM (iPhone) or Network & Internet → SIMs → Add eSIM (Android) and scan it — a manual code is included too. Keep your home line as default until arrival. When you land at Changi, your Flysimio line connects automatically to a Singapore network — perfect even for a few-hour transit.

Singapore is compact, so most visitors need less than they expect. For maps, messaging, and email, roughly 300 MB a day is plenty, so a 1–3 GB plan easily covers a short stay or a long layover. For a week of social media, photos, and music, around 5 GB is comfortable; a two-week regional base works well on 10 GB. Heavy streamers or anyone tethering a laptop should plan for 1.5 GB or more per day or choose an unlimited daily plan. Use the calculator above to size it, and top up mid-trip if you run low.

Flysimio runs as a second line beside your usual SIM, so you keep your home number for calls and texts while your Singapore data flows over the eSIM — standard dual-SIM behaviour on iPhone XS and later and most Android phones from 2018. After installing, set the Flysimio eSIM as your cellular-data line and turn on Data Roaming for that line only; it simply lets the eSIM connect to Singapore networks, with no roaming fees. Keep your home SIM on for messages and calls, or switch it off to avoid your own carrier's charges. If you're unsure about your model, the compatibility page confirms it before you buy.

Every Flysimio Singapore plan includes mobile hotspot at no extra cost and without throttling, so you can tether a laptop or tablet or share with a travel companion and use your full allowance freely — great for working from a café between meetings. As a data-only eSIM it has no Singapore phone number, but that rarely matters: WhatsApp, FaceTime, Messenger, and Google Meet handle calls and messages over data, and your home number stays reachable on your primary SIM. You stay connected island-wide without the per-minute charges of traditional roaming.

For a long Changi layover or a two-day stopover, a small 1–3 GB plan on a 7-day validity is the cheapest way to stay online — and still beats a day of roaming. For a week exploring the city or a regional base, a 5–10 GB plan or an unlimited daily option gives you room to navigate, stream, and share freely. Because Flysimio gives you six months to activate, you can buy before you leave and the validity only starts when your eSIM first connects in Singapore. No contract, nothing to cancel — the plan stops when it's done, and you can top up or rebuy for your next trip.
