Singapore eSIM vs Local Prepaid SIM: Which Should You Choose?

Airport SIM counters have 15-30 minute queues during peak arrivals. Roami eSIM activates in 5 minutes — be online the moment you land.
No Passport Scanning
Singtel and StarHub require passport scanning in-store. Roami eSIM requires zero ID — no scanning, no forms.
No Cash-Only Counters
StarHub's Changi counter is cash-only. Roami accepts all major credit cards, Apple Pay, Google Pay, and PayPal — no cash needed.

Is 5G really available everywhere in Singapore? What about Sentosa and Changi Airport?
Yes — Singapore has one of the world’s most comprehensive 5G networks. 5G coverage exceeds 95% of the island, including Changi Airport, Sentosa, Marina Bay Sands, Orchard Road, Gardens by the Bay, and all MRT stations and tunnels. Singtel, StarHub, and M1 have all rolled out extensive 5G. Even in underground shopping malls and MRT tunnels, you’ll typically have strong 5G or 4G+ signal. Roami auto-connects to the strongest carrier. -
Is a Singapore local SIM cheaper than an eSIM? Should I buy one at Changi?
Local prepaid SIMs at Changi cost around S$12-S$20 for 3-7 days of data. The prices aren’t dramatically higher than Roami, but the convenience difference is huge: you’ll queue 15-30 minutes, show your passport for scanning, and deal with cash-only counters (StarHub’s UOB counter at Changi is cash-only). Roami costs around the same or slightly less and you skip all of that — buy online, scan QR, done. For a short trip, the time saved is worth more than any small price difference. -
Will my eSIM work at Marina Bay Sands, Gardens by the Bay, and other busy tourist spots?
Yes — all three carriers have dense network infrastructure at major tourist attractions. Even during peak hours (evenings at Marina Bay, weekends at Sentosa), you’ll have strong 5G for photos, video calls, and maps. Singtel has additional capacity at large events, and Roami auto-switches to the best carrier if one network is congested. -
Do I need to show my passport or register my ID for a Singapore eSIM?
No passport or ID needed with Roami. Singapore law requires local prepaid SIMs to be registered with a passport (Singtel and StarHub scan passports in-store), but Roami is an international data eSIM that bypasses this requirement. No passport scanning, no forms, no store visit — just buy online and go. -
Can I use my Singapore eSIM in Malaysia, Indonesia, or Thailand?
Yes — Roami eSIM works across the region. Singapore is a regional travel hub, and many visitors continue to Kuala Lumpur, Bangkok, or Bali. Roami’s multi-country plans cover Singapore, Malaysia, Thailand, Indonesia, and more. Local Singapore SIMs (Singtel/StarHub/M1) either don’t offer roaming or charge expensive daily add-ons with limited data (e.g., Singtel S$12 plan includes only 3GB roaming). Roami gives you seamless cross-border connectivity. -
How fast is 5G in Singapore? Can I do video calls and remote work?
Singapore’s 5G delivers typical speeds of 100-400 Mbps, with peaks above 1 Gbps in some areas. That’s more than enough for Zoom, Teams, Google Meet, and large file uploads. For business travelers, a 10GB or 20GB plan is recommended for daily video calls and hotspot sharing to your laptop. Latency is very low (10-20ms), making remote work feel like you’re in the office. -
Is buying a SIM at Changi Airport really that bad?
It’s not the worst experience in the world, but it’s an unnecessary hassle. Changi has Singtel, StarHub, and M1 counters — queues can be 15-30 minutes depending on your arrival time (especially morning flights from Europe/US). You’ll need to show your passport for scanning, and StarHub’s counter is cash-only (no credit cards). Some tourists also report being upsold to more expensive S$38-S$50 packages. Roami lets you skip all of this — you’re online the moment you step into the arrivals hall. -
Singapore hotels have great WiFi — do I really need an eSIM?
Hotel WiFi in Singapore is generally good, but it’s not always reliable for everything. Many hotels require logins that expire daily, cap bandwidth for streaming, or block certain apps. More importantly, WiFi only works in your room and lobby — you don’t have data when you’re out exploring. With an eSIM, you can check MRT schedules on the go, find hawker centre recommendations in real time, and share photos instantly. For the price of a coffee, you get connectivity everywhere. -
What if I accidentally delete my Singapore eSIM before my trip?
No problem. Log into your Roami account to re-download the QR code — takes about 1 minute. We recommend saving it as a screenshot or PDF when you first receive it, just in case. -
When does the validity period of my Singapore eSIM start?
The plan validity starts when you connect to a local network in Singapore, not when you buy or install it. So you can purchase and install weeks before your trip without losing any plan days. A 7-day plan gives you 7 full days from first connection.
