What makes a good Singapore eSIM?
- Networks and 5G: Check which networks a plan runs on and whether it has 5G. eSIMology's plans include 5G where the network offers it, and your phone must support 5G too.
- Plan size for your trip: For a 7-day trip of standard use (about 4.9 GB in all), 5 GB for 30 days fits. For 14 days of standard use (about 9.8 GB in all), 10 GB for 30 days fits. Heavy users on a week-long trip (about 12.6 GB in all) should look at 2 GB a day for 7 days.
- Speed after the daily allowance: On a daily plan, speed drops to 1 Mbps once the day's data runs out, and eSIMology prints that on every plan. If you need more, pick a bigger daily allowance, up to 10 GB a day, or a larger fixed plan such as 50 GB for 30 days.
- Where your data goes, and top-ups: Your data reaches the internet through Hong Kong. Most eSIMology plans can be topped up, and you check data left and top up on a web page, with no app to install.
Which Singapore eSIM plan fits your trip: fixed GB or a daily allowance?
Match the plan to your trip length and data use. Each bullet below is a typical Singapore trip.
- A three-day city break in Marina Bay and Orchard Road: a fixed pack covers light use, so 1 GB for 7 days does the job. For steady maps, photos and ride-hailing, choose 1 GB a day for 3 days.
- A week across Sentosa, Chinatown and Little India: 5 GB for 30 days covers standard use, and most plans can be topped up. Heavy users who want a set amount each day should take 2 GB a day for 7 days.
- A fortnight with Grab, Gojek or ComfortDelGro rides and WhatsApp: 10 GB for 30 days suits standard use. Heavier days fit 2 GB a day for 15 days.
- Unlimited by the day: Holafly sells unlimited plans by the day for 3, 5, 7, 10, 15 or 30 days. Saily sells those too, from 1 to 30 days, plus 90 and 365, alongside fixed-GB plans.
