## 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.
