As we step into May 2025, Singapore’s SIM-only market continues to evolve, with telcos offering increasingly competitive plans. For consumers looking for affordable, data-heavy mobile options without a contract, three names dominate the scene: GOMO by Singtel, SIMBA (formerly TPG Mobile), and Giga by StarHub. Each brings something unique to the table, whether it’s massive data allowances, low international rates, or no-throttle usage policies. Here’s an updated breakdown to help you decide which is the best fit based on your usage needs and budget.
GOMO by Singtel – Seamless Network Backed by a Powerhouse
GOMO, backed by Singtel, remains a strong player in 2025 with its focus on simplicity and network strength. Its flagship $25/month plan offers 60GB of local data, 500 minutes of talk time, 500 SMS, and free incoming calls. For travelers, GOMO provides 2GB of monthly roaming data usable in selected destinations including Malaysia, Indonesia, and Thailand. Users enjoy the robust Singtel network, known for its speed and low latency, making it ideal for mobile gamers and heavy streamers. The GOMO app allows full control of the plan, including top-ups, roaming add-ons, and instant SIM replacement, streamlining the user experience.
SIMBA – Budget King with Unlimited Edge
SIMBA, previously known as TPG Mobile, has carved a niche with its extremely cost-effective plans. Its most popular plan remains at just $10/month, offering 100GB of 4G/5G local data, 300 minutes of outgoing calls, and 100 SMS. SIMBA distinguishes itself by offering unlimited local data with no speed throttle up to the plan’s cap, which is rare in this price segment. Despite some criticisms over coverage gaps in underground areas or certain HDB zones, SIMBA has made significant strides in improving its 5G network performance. As of May 2025, the telco has expanded its roaming coverage in ASEAN regions, making it more travel-friendly.
Giga by StarHub – Flexible, Fast, and Feature-Rich
Giga, StarHub’s digital sub-brand, targets users who demand flexibility and high performance. Its $18/month plan includes 45GB of local data, 1,000 minutes of outgoing calls, 1,000 SMS, rollover of unused data, and optional roaming packs. Giga stands out with its data rollover feature—unused data rolls over for the next two months, giving light users extra value. It operates on StarHub’s reliable 5G infrastructure, offering strong speeds in urban hubs and business districts. The Giga app also supports eSIM activation, useful for multi-device users or frequent SIM switchers.

Which Plan Should You Choose in May 2025?
Your ideal choice will depend on your priorities. If network reliability and international use matter most, GOMO is your go-to. Those on a tight budget who consume massive data should lean towards SIMBA. For users who like to save unused data and value flexibility, Giga hits the sweet spot. It’s also worth noting that customer service and app usability play important roles—Giga and GOMO both offer intuitive app experiences, while SIMBA’s interface has improved but still lacks polish.
For dual SIM users or those with modern iPhones and Androids, eSIM support in Giga and GOMO is a major advantage, allowing users to toggle between work and personal numbers seamlessly. Meanwhile, SIMBA is a standout for students or casual users who prioritize data over premium features.
Conclusion
In May 2025, Singapore’s SIM-only market is more competitive than ever, and the best choice depends on what you value most. GOMO offers peace of mind with excellent coverage, SIMBA delivers unbeatable value for data lovers, and Giga balances flexibility with solid network performance. Evaluate your data habits, travel frequency, and willingness to spend before locking in your choice.
