Using mobile data in Singapore
Coverage during your trip
Coverage is generally strong across the city-state, including central districts and established residential areas. Indoor reception still depends on the building, basement, and selected local network, so public Wi-Fi can remain useful in large venues.
Choosing and preparing your plan
Short visits often need less data unless you stream frequently or tether another device. Install before departure, keep the eSIM turned off until the appropriate activation time, and verify that your phone is carrier-unlocked before purchasing.
Singapore eSIM questions
Why isn't my eSIM working in Singapore?
Confirm that the eSIM is selected for mobile data, data roaming is enabled, and airplane mode is off. Restart your phone after arrival; if it still does not connect, check the APN instructions supplied with the plan.
How do I check my Singapore eSIM data balance?
Sign in to Flowsus, open My eSIMs, and select the active eSIM to see its remaining data and latest usage update.
Can I keep my WhatsApp number while using an eSIM?
Yes. Keep your primary SIM active for your phone number and select the Flowsus eSIM for mobile data. WhatsApp keeps its registered number unless you choose to change it inside the app.
Can one eSIM profile be used on multiple phones?
Usually not. An issued eSIM profile is intended for one device. Do not delete an installed eSIM unless Flowsus support instructs you to do so. Contact support before changing phones or attempting to reinstall it.
