RedEx
Redex prioritizes access to the Singtel 5G network; this operator has a higher base station density across Singapore than StarHub and M1.
In Singapore’s Central Business District (CBD) and the Marina Bay Sands area, measured downlink speeds are stable between 180Mbps to 300Mbps, with upload speeds around 45Mbps.
By utilizing Singapore local or near-end (Hong Kong) internet gateways, its network latency (Ping) is only around 25ms, which is far superior to roaming eSIMs that usually route through Europe (typically 150ms+).
It supports full-speed personal hotspot sharing.
After installation, both iPhone and Android devices can automatically recognize the APN without the need for manual setting changes.
Features
-
Network Standard: Defaults to the Singtel 5G network, with seamless automatic switching to 4G LTE in remote areas.
-
Hotspot Rules: Supports full-speed personal hotspot sharing, allowing multiple devices to connect simultaneously with no limit on the number of devices.
-
Activation Time: A QR code is generated immediately after purchase; it is plug-and-play upon arrival in Singapore with no real-name authentication (eKYC) required.
-
Calls & SMS: Data-only package; does not provide a +65 local number and does not support traditional voice calls or SMS transceiving.
Price Reference
-
Short-term Trial: Approx 4.50 USD for 1GB of data (7 days valid), suitable for transit travelers who only need to hail rides or check maps.
-
Mainstream Package: Approx 12.00 USD for 5GB of data (30 days valid), meeting the regular travel needs for about a week.
-
Large Data Pack: Approx 25.00 USD for 20GB of data (30 days valid), bringing the cost per GB down to around 1.25 USD.
Target Users
-
High-frequency Business Travelers: Those who need to conduct Zoom video conferences or transfer large files via Slack while on the move (sensitive to packet loss).
-
HD Content Creators: Bloggers who need to upload 4K video footage to Instagram Stories or TikTok (stable upload speeds).
-
Instant Gamers: Users playing Mobile Legends or PUBG Mobile during their trip (requires Ping lower than 40ms).
OceanEsim
OceanEsim aggregates signal resources from two operators, StarHub and M1, providing more flexible coverage than a single network.
In measured data, its high-capacity packages (such as 30GB or 50GB tiers) compress the cost per GB to below 1.00 USD.
Although the longer data routing path causes Ping values to hover between 110ms to 130ms, making it unsuitable for high-frequency real-time interaction, its bandwidth is not restricted.
Downlink speeds measured around Clarke Quay remain between 80Mbps to 120Mbps.
It supports unthrottled personal hotspot sharing and typically has no hidden Fair Usage Policy (FUP) speed limits before the 50GB is used up, making it an economical choice for heavy users with multiple devices.
Features
-
Network Standard: Supports switching between dual operators StarHub/M1, automatically connecting to 5G or 4G LTE depending on the area.
-
Hotspot Rules: Allows opening a personal hotspot and does not restrict the type of connected devices (supports connecting laptops or game consoles).
-
Activation Time: The QR code is valid for a long time; it is recommended to scan and install it via the app before departure, and it can be activated by turning on roaming after landing in Singapore.
-
Value-added Services: Some packages support real-time data top-ups via the App without needing to replace the eSIM card.
Price Reference
-
Light Use: Approx 5.50 USD for 3GB of data (30 days valid), suitable for backup or short layovers.
-
Standard Travel: Approx 16.00 USD for 10GB of data (30 days valid), sufficient for most map navigation and social media needs.
-
Heavy Data: Approx 38.00 USD for 50GB of data (30 days valid), with a cost per GB of only about 0.76 USD, offering extremely high cost-performance.
Target Users
-
Digital Nomads: Remote workers who need to work for long periods via hotspots in cafes.
-
Heavy Streaming Consumers: Travelers who watch more than 2 hours of long-form video on Netflix or YouTube daily during their trip.
-
Family/Group Trips: Scenarios where one person buys a large data pack and turns on a hotspot for the whole family (3-4 devices) to share.
Saily
Saily was launched by cybersecurity giant Nord Security (parent company of NordVPN), with an underlying architecture that prioritizes routing data through encrypted nodes.
In Singapore measurements, it primarily locks onto the Singtel network.
Although the secure routing mechanism causes Ping values to stay between 90ms to 120ms, its packet loss rate is strictly controlled below 0.1%, making the connection extremely stable.
In high-density areas such as Bugis Junction and the CBD, downlink speeds are stable between 85Mbps to 150Mbps.
Its App utilizes “direct-connect activation” technology, requiring only 3 clicks from purchase to installation without scanning a QR code, greatly lowering the technical threshold for first-time eSIM users.
Features
-
Network Standard: Accesses the Singtel network (connecting to 5G or high-quality 4G+ depending on base station conditions).
-
Installation Method: Minimalist App activation, supporting automatic configuration at the iOS/Android system level without manual APN entry.
-
Security & Privacy: Follows strict privacy protection standards by default and does not log user browsing history data.
-
Top-up Logic: Supports overlaying data packs on the current eSIM without needing to reinstall a new eSIM card.
Price Reference
-
Short-term Experience: Approx 4.00 USD for 1GB of data (7 days valid), moderately priced and suitable as a secure backup network.
-
Weekly Commute: Approx 13.00 USD for 5GB of data (30 days valid), sufficient to cover most business travel needs.
-
Half-month Travel: Approx 22.00 USD for 10GB of data (30 days valid), with a cost per GB of about 2.2 USD, slightly higher than aggregated competitors.
Target Users
-
Privacy-conscious Business Travelers: Users accustomed to using VPNs who are skeptical of public Wi-Fi security and need an independent secure cellular network.
-
Non-tech Savvy Users/Seniors: Users who find phone settings headache-inducing and need “dummy-proof” operation without dealing with APNs or QR code scanning.
-
Apple Ecosystem Users: iPhone users accustomed to using Apple Pay who pursue the minimalist aesthetic of the App interface.
Airalo
Airalo’s Singapore-exclusive package “Connect Lah!” adopts a dual-network access strategy using Singtel LTE and StarHub, making it one of the most compatible solutions on the market.
Measurements across Singapore (including Sentosa Island and Jurong Industrial Estate) show its 4G/LTE signal residence rate is as high as 98%.
While average downlink speeds are locked at a moderate level of 40Mbps to 80Mbps, and Ping values fluctuate between 120ms to 180ms due to roaming routing, its TCP connection stability is extremely high. ”
Flow interruption” rarely occurs when switching base stations on the MRT East-West Line.
The App features a comprehensive API interface, supporting real-time usage monitoring (delay not exceeding 5 minutes) and the Airmoney reward system.
Features
-
Network Standard: Aggregates Singtel/StarHub dual networks, primarily connecting to 4G LTE with 5G signals in some areas.
-
Installation Method: Supports one-click installation within the App (iOS/Android), while also providing traditional QR code emails.
-
Data Query: Data update frequency is extremely high; you can see almost in real-time the data you just consumed, making budget control easy.
