Methodology
Speed test methodology
We tested mobile speeds in Singapore across local carriers using Ookla Speedtest and Fast.com from urban, suburban, and tourist locations. Tests ran at peak (10am-2pm) and off-peak (6am-8am) hours over a seven-day period. Each provider was tested on the same device to eliminate hardware variables.
Results

| HelloRoam | 355 Mbps | 71 Mbps | 15 ms | 5.0/5 |
| Airalo | 327 Mbps | 65 Mbps | 18 ms | 4.7/5 |
| Holafly | 298 Mbps | 60 Mbps | 21 ms | 4.4/5 |
| Saily | 270 Mbps | 54 Mbps | 24 ms | 4.1/5 |
| Nomad | 241 Mbps | 48 Mbps | 27 ms | 3.8/5 |
Speed data collected May 2026. Median of 5 consecutive Ookla Speedtest runs per provider.
Infrastructure
Singapore network infrastructure
Singapore runs on 4 major mobile networks — Singtel, StarHub, and M1 — with 5G as the top available standard. Measured download speeds average 355 Mbps, placing Singapore in the top tier globally. 5G coverage in Singapore is widespread. Nationwide 5G standalone coverage achieved in 2025; all carriers offer 5G 5G maintained 300+ Mbps consistently across the entire island including Sentosa and East Coast Park. All three major networks deliver near-identical performance in Singapore due to the small island geography.
| Operator | Technologies |

| StarHub | 5G |
5G Rollout Status
5G coverage in Singapore is widespread. Most urban and suburban areas support 5G on compatible devices. Nationwide 5G standalone coverage achieved in 2025; all carriers offer 5G
Location Variance
Urban vs rural speed comparison
Speed variance across location types in Singapore.
| Location Type | Avg Download | Avg Upload | Signal Strength |
|---|---|---|---|
| Urban / City Center | 355 Mbps | 71 Mbps | Excellent |
| Suburban | 248 Mbps | 50 Mbps | Good |
| Tourist Areas | 284 Mbps | 57 Mbps | Good |
| Rural / Remote | 124 Mbps | 25 Mbps | Limited |
City centers in Singapore deliver the strongest speeds with direct line-of-sight to Singtel's tower infrastructure. Suburban areas retain 65-75% of urban throughput. Remote locations drop to 30-40% but remain adequate for navigation and messaging.
Time of Day
Peak vs off-peak performance
Morning speeds (06:00-10:00 local) in Singapore consistently outperformed evening readings by 20-30%. The congestion window between 18:00-22:00 produced the slowest results across all providers.
Weekend speeds in Singapore were 10-15% faster than weekday readings during business hours, likely due to reduced enterprise traffic on Singtel's network.
Peak tourist season (Dec-Jan, Jun-Aug) adds additional congestion in popular areas. Consider purchasing a larger data tier during these periods to compensate for reduced effective throughput.
Routing
Network partners and carrier routing
| Provider | Carrier Partner | Network Type | Routing |
|---|---|---|---|
| HelloRoam | Singtel | 5G | Tier-1 Direct |
| Airalo | Singtel | 5G | Tier-1 Direct |
| Holafly | Singtel | 5G | MVNO |
| Saily | Singtel | 5G | MVNO |
| Nomad | Singtel | 5G | MVNO |
All 5 providers route Singapore eSIM traffic through Singtel as the primary network partner. Speed differences between providers stem from prioritization agreements rather than carrier selection.
Tier-1 routed providers (HelloRoam, Airalo) receive the same network priority as local postpaid subscribers. MVNO-routed providers may experience deprioritization during peak congestion windows, resulting in 10-20% lower speeds at peak times.
Airport
Changi (SIN) connectivity test
Speed tests at Changi (SIN) delivered 302 Mbps download on Singtel's network. Airport congestion reduced speeds by approximately 15% compared to city center readings.
eSIM activation at Changi (SIN) was instant. No need to find a SIM kiosk or wait in line. Local airport SIM cards cost $12-30 for 100GB / 7-28 days from Singtel or StarHub or M1.
Detailed Results
Speed Test Deep Dive for Singapore
Our speed tests in Singapore confirm that 5G connectivity on Singtel's network meets the requirements for video calling, navigation, social media, and streaming. Travel eSIM speeds matched local SIM card performance within a 5% margin across all test locations.
Rural Speed
Speed Outside Major Cities in Singapore
Singtel provides the widest rural coverage in Singapore. Rural areas have adequate but slower coverage. Download offline maps and essential content before traveling to remote areas. Travel eSIM providers route through the highest-coverage carrier available, but no carrier eliminates all rural dead zones.
Southeast Asia
Southeast Asia Network Context for Singapore
Southeast Asian islands present the biggest connectivity challenge for eSIM users. Coverage on main islands and popular beach destinations is typically strong. Smaller, less-developed islands may have limited or no signal. Download offline maps and important documents before taking a ferry.
Monsoon season in Singapore can affect mobile signal quality. Heavy rainfall reduces signal strength by 5-15%. Lightning-related tower outages are possible but typically last under an hour. Plan data-heavy tasks for dry periods and keep offline navigation cached.
Cafe WiFi culture is strong across Southeast Asia. Most tourist-area restaurants and coffee shops offer free WiFi. Use these connections for streaming and large downloads, and reserve your eSIM data for on-the-go navigation. A 3-5GB plan stretches further with this WiFi-first strategy.
Seasonal Impact
How Tourist Season Affects Speed in Singapore
Network performance in Singapore varies by season. During Dec-Jan, Jun-Aug, tourist-heavy areas experience higher network congestion, reducing effective speeds by 15-30% in popular zones. We recommend buying one data tier higher than your estimated usage during peak season. Off-peak travel delivers the best network performance and often lower eSIM pricing from providers running seasonal promotions.
Verdict
Speed verdict for Singapore
Singapore ranks in the top tier speed bracket for travel eSIM performance in 2026. Average downloads of 355 Mbps on Singtel's 5G network are more than sufficient for streaming, video calls, and navigation.
Nomad delivered the best combination of speed and value across our testing. For pure speed performance, all Tier-1 routed providers performed within 10% of each other on the same carrier network.
