This review covers M1's network performance, customer service, additional features, competitive positioning against Singtel and StarHub, and frequently asked questions.

Introduction

Singapore's first digital network operator, M1 Limited (formerly MobileOne), is a private telecommunications company founded in 1994 as a subsidiary of Keppel Ltd., serving over 2 million mobile customers and more than 200,000 fixed broadband households with mobile, fixed-line, and fibre services across Singapore's 733 km² (283 sq mi) island territory.

M1 delivers a fully deployed 5G Standalone (SA) network covering the entire island of Singapore, recording a median 5G download speed of 420.22 Mbps — statistically on par with market leader Singtel's 421.79 Mbps — and earned the Ookla Best 5G Video Experience award (5G Video Streaming Score: 87.81) for January through June 2025, according to the Ookla Speedtest Connectivity Report H1 2025. M1 also achieved the best 5G Consistency in Singapore, with 94.2% of samples meeting or exceeding 25 Mbps download and 3 Mbps upload thresholds.

Network Coverage And Performance

M1 covers Singapore's entire 733 km² land area with 4G LTE service and maintains a fully deployed 5G Standalone network island-wide, including maritime 5G coverage along the southern coast, according to Keppel Ltd.'s official network announcement published May 2025. Singapore's compact geography means M1's coverage blankets all 28 Urban Redevelopment Authority planning areas, from Woodlands in the north to Sentosa in the south.

M1 launched commercial 5G SA services in 2021, became Singapore's first operator to move its entire back-end system to a cloud-native platform, and describes its 5G SA product as M1 True 5G. The network originally covered 50% of the island at public launch, expanded to 75% by end-2021, and reached full island-wide deployment by 2022 — ahead of the Infocomm Media Development Authority (IMDA) mandated schedule, according to M1's official IMDA licensing disclosures.

4G And 5G Availability

M1 operates 4G LTE across all Singapore planning areas and a 5G Standalone (SA) network island-wide, with 5G Non-Standalone (NSA) launched in September 2020 and 5G SA commercially launched in 2021. The 5G SA network runs on Nokia's 5G Core cloud-native infrastructure and uses sub-6 GHz spectrum allocated by IMDA. M1's 5G Consistency score of 94.2% — the highest among Singapore's three operators — confirms reliable 5G throughput, not merely nominal availability, according to Ookla Speedtest Intelligence data for January through June 2025.

Key districts with confirmed 5G SA service include the Central Business District, Marina Bay Financial Centre, Orchard Road, Ang Mo Kio, Bishan, Chinatown, Clementi, Pasir Ris, Paya Lebar, Sengkang, Tampines, and Woodlands. M1's 5G SA network delivers peak download speeds of approximately 1 Gbps in optimal conditions, according to M1's technical specifications published at launch.

Speed Test Results

M1 delivers a median overall download speed of 102.03 Mbps and a median 5G download speed of 420.22 Mbps across Singapore, placing it second among local operators for both all-technology combined and 5G speeds, according to the Ookla Speedtest Connectivity Report published for January through June 2025. The table below shows available speed data across Singapore's primary commercial and residential districts.

Customer Service And Support

M1 operates five customer service channels — phone hotline, in-store service, website live chat, the My M1 mobile app, and social media support — with physical retail stores located across Singapore's major towns and shopping malls. M1's customer satisfaction profile on Trustpilot reflects significant dissatisfaction, with the majority of reviews citing difficulties reaching live agents and inconsistent in-store service redirection, according to Trustpilot review data published through March 2026.

M1 Limited strengths and weaknesses summary for Singapore subscribers

Advantages

• Best 5G Consistency In Singapore: M1 leads all Singapore operators with a 5G Consistency score of 94.2% — meaning 94.2% of M1's 5G samples met or exceeded 25 Mbps download and 3 Mbps upload — the highest threshold measurement among local carriers, according to Ookla Speedtest Intelligence H1 2025.

• Best 5G Video Streaming Experience: M1 earned the Ookla Best 5G Video Experience award with a 5G Video Streaming Score of 87.81 for January through June 2025, making it the top-performing operator for streaming-heavy 5G users in Singapore.

• Fully Deployed Island-Wide 5G SA Network: M1 completed full island-wide 5G Standalone deployment ahead of IMDA's mandated schedule, including maritime 5G coverage along Singapore's southern coast — a coverage breadth unmatched by operators still completing 5G SA rollouts globally, according to Keppel Ltd. announcements published May 2025.

• Competitive 5G Peak Speeds: M1's median 5G download speed of 420.22 Mbps places it statistically on par with Singtel (421.79 Mbps) and significantly ahead of StarHub (369.39 Mbps), confirming M1's 5G performance is competitive at the top tier of Singapore's mobile market, according to Ookla H1 2025 data.

Disadvantages

• Lower All-Technology Combined Speeds: M1's median all-technology combined download speed of 102.03 Mbps is significantly below Singtel's 296.76 Mbps — nearly one-third of Singtel's output — indicating M1's non-5G network infrastructure underperforms versus the market leader for users outside optimal 5G zones, according to Ookla H1 2025.

• Poor Customer Service Satisfaction: Trustpilot reviews through March 2026 show widespread dissatisfaction with M1's customer service, with recurring complaints about AI hotline ineffectiveness, lengthy live chat queues, and in-store redirection to online channels for issues that require human resolution.

• Fewer Plan Tiers And Limited eSIM Options Than Competitors: M1 offers 2 to 3 main tourist SIM plan types versus Singtel's and StarHub's 6 to 8 options, and provides more limited eSIM availability compared to competitors, restricting flexibility for visitors and users with complex connectivity requirements, according to carrier plan comparisons published by Truely in October 2025.

M1 Vs Competitors

Singapore's mobile market operates as a three-operator duopoly led by Singtel with approximately 4.5 million mobile subscribers, followed by StarHub with 2.4 million, and M1 with over 2 million — with a potential market restructuring underway as Keppel's planned sale of its 83.9% M1 stake to Simba Telecom proceeds, which would create a merged entity of 3.2 million connections challenging StarHub for second position, according to Operator Watch analysis published December 2025. M1 holds approximately 22% of Singapore's mobile subscriber market based on total subscriber ratios across the three operators.

Singtel leads on overall network quality, all-technology speeds, and subscriber scale — making it the strongest choice for users who prioritise raw speed and the broadest coverage. M1 delivers 5G performance statistically equivalent to Singtel, with the additional advantage of superior 5G consistency and video streaming — making it ideal for heavy 5G video users who prioritise streaming reliability over all-network average speeds. StarHub competes on bundled offerings and enterprise services but trails both operators on 5G speeds.
