Quick answer: If you are flying into Singapore and dreading T-Mobile’s roaming charges, any of these local SIM cards will get you online for a fraction of the cost. For a short tourist trip, pick up a Singtel hi!Tourist SIM at the airport; if you are staying a month or more, the no-contract monthly plans from GOMO, Circles.Life, or SIMBA give you massive data and generous roaming to neighbouring countries.

Landing in Singapore with your T-Mobile global roaming can feel like turning up with an umbrella in a drizzle — it works, lah, but it is not exactly built for the downpour. The local SIM game here is serious: more data than you could scroll through, 5G speeds that load your Grab before you blink, and roaming bundles that make weekend runs to JB or Bangkok feel seamless. Here are the picks that actually make sense.
Singtel
Singtel is the old faithful of Singapore mobile networks, with a tourist SIM you can grab at Changi Airport the moment you clear immigration. The hi!Tourist SIM starts at $12 for 100GB of local data over 14 days, plus unlimited social messaging and 30 minutes of international calls — more than enough to map your way to the best nasi lemak without a care. If you want to tap onto the MRT as well, the $18 version doubles as an EZ-Link card with $3 pre-loaded, so you skip the queue at the ticket machine. They have been doing eSIM for ages, too, if you would rather not fiddle with a tiny plastic tray.
Coverage is everywhere — Singtel’s network consistently wins top marks in Asia-Pacific telecom rankings for quality, and you will feel it in the lifts and underground of Orchard Road malls. Grab the SIM at any Changi Airport counter (open 24/7) or at 31 Exeter Road, #01-01, Comcentre, Singapore 239978. Call +65 6838 3388 or visit www.singtel.com.

StarHub
StarHub’s Travel Prepaid SIM feels like a generous local plan that follows you across borders without making you change cards in a sweaty taxi. The $12 pack gives you 100GB for 10 days and 1GB of roaming data — handy for a quick pop-over to JB or Batam. If you are island-hopping across the region, the $32 version stretches 100GB over 30 days across 17 countries, so you can order your Grab in Bangkok, KL, or Jakarta on the same number. Free social app data and IDD credits are bundled in, and you top up through their app without needing to hunt down a 7-Eleven.
They have counters at Changi and selected retailers around town, and their head office sits at 67 Ubi Avenue 1, #05-01, StarHub Green, Singapore 408942. Phone: +65 6820 1633. Website: www.starhub.com.
M1
M1’s Tourist SIM plays smart for the eSIM crowd — you can scan a QR code before you even leave the plane and land with a working line. For $12 you get 100GB over 15 days, and the $14 plan shares 100GB across five countries (Malaysia, Indonesia, Taiwan, Hong Kong, and Macau) for 30 days with no activation fees for roaming. That is the kind of fuss-free regional connectivity that makes a weekend wedding in Bali or a client lunch in Penang feel instantly sorted.
Find them at Changi Airport or their main office at 10 International Business Park, Singapore 609928. Call +65 6680 1627, or browse www.m1.com.sg.

GOMO
GOMO runs on Singtel’s network but wears a no-contract outfit that makes it dead simple for anyone who hates being tied down. Their 5G+ Value Plan is currently priced at $12.33 a month (introductory) and throws in 300GB of local data, 800 minutes of talk time, and — this is the part that turns heads — up to 300GB of free roaming in Malaysia. Manage everything through their app, and unused data rolls over to the next month. If you are in and out of Johor Bahru for family or food, this one feels like it was designed for you.
GOMO is an online-only service with support at gomo.sg, or call Singtel’s customer service at +65 6838 3388. For stays under a month, Prepaid SIM Cards in Singapore for Effortless Connectivity breaks down the short-term options in more detail.
Circles.Life
Circles.Life built its name on letting you customise your plan like you are at a hawker centre picking sides — add a little more roaming this month, a data boost the next. Their 650GB 5G plan at $15 a month comes with unlimited outgoing calls and 10GB of roaming to seven destinations, covering Australia, Hong Kong, Thailand, and a few more. It is entirely app-based, so you sign up, tweak your extras, and track usage all from your phone. For the digital nomad who might need extra roaming one month and less the next, that flexibility is a big draw.
Their office is at 10 International Business Park, Singapore 609928. Call +65 6717 1680 or visit www.circles.life/sg. And if your phone needs an upgrade to fully enjoy 5G speeds, our list of Mobile Phones in Singapore has a few solid picks.
SIMBA
SIMBA is the independent upstart running its own 5G network, and they are not shy with the data. For $12 a month, you get 500GB, 600 local minutes, and 8GB of roaming data — good for quick trips. What makes them interesting are the daily roaming packs you can stack if you are a heavy traveller bouncing between countries. There is no contract, eSIM is supported, and the price stays flat, so you can treat it like a long-term tourist line that never overstays its welcome.
SIMBA’s office is at 1 Kaki Bukit View #02-10 Techview, Singapore 415941. For support, head to SIMBA’s help portal or browse plans at www.simba.sg.
MyRepublic
MyRepublic started as a broadband provider, and their mobile plans reflect that all-in-one thinking — especially if you are already using them for home internet. The 5G Best Value Plan at $17.95 a month delivers 550GB of data, 1,200 minutes, and 12GB of roaming across Malaysia, Indonesia, and Thailand. There is free international data for lighter use outside those countries, and eSIM support means you can switch over while you are still packing. Bundle it with their broadband for discounts, and the savings can feel, well, very Singaporean.
You can visit them at 11 Lorong 3 Toa Payoh, Block B #04-11/15 Jackson Square, Singapore 319579, call +65 6717 1680, or sign up at mobile.myrepublic.com.sg.

How to choose
Start with your trip length and where you’ll go next. If you are here for two weeks or less, a tourist SIM from Singtel, StarHub or M1 is the easiest: you pay a flat fee, use a ton of data, and toss it. If you are staying a month or more — or commuting regularly to Malaysia — the no-contract monthly plans from GOMO, Circles.Life, SIMBA, and MyRepublic often work out cheaper and give you a permanent local number.
Think about roaming, too. A $12 tourist SIM might only cover Singapore; a $14 M1 plan already includes five neighbouring countries. For boundless roaming, StarHub’s $32 pack covers 17. For frequent Malaysia trips, GOMO’s included 300GB roaming is hard to beat. All the monthly plans allow you to add more roaming data as you need it, so no need to overbuy.
eSIM compatibility is another quiet decider. If your phone supports it (most newer iPhones and flagship Androids do), you can activate your line from the terminal instead of queuing at a counter. Singtel, M1, Circles.Life, SIMBA and MyRepublic all have eSIM options; StarHub and GOMO mostly rely on physical SIMs, so check the latest on their sites.
Price-wise, tourist SIMs range from $12 to $32; monthly no-contract plans from about $12 to $18. For a short stay, $15 gets you overwhelmed with data. For a long stay, $15 a month with roaming included feels like a steal compared to international roaming passes.

Grab a tourist SIM at the airport for a short trip, or for longer stays, a no-contract plan from GOMO, Circles.Life, or SIMBA will feel like having a local number without the lock-in.
