Prepaid Data Plans for Singapore
esimbloom lists 17 prepaid eSIM plans for Singapore from $0.36 (the smallest is 100MB for 7 days). Every plan is data-only — mobile internet for maps, messaging and bookings, but no local phone number or SMS — and prepaid: pay once, no contract, no roaming charges.
Buy your plan before departure, receive the QR code by email, and install it when ready. The data allowance activates when you first connect in Singapore, so you can prepare the eSIM in advance without starting the validity period early. No physical SIM card, no contract, and no surprise roaming charges from your home carrier.
Installing and Activating Your Singapore eSIM
Your device must support eSIM technology and be carrier-unlocked. Most iPhones from XS onward, recent Samsung Galaxy and Google Pixel models, and many other smartphones are compatible. After purchase, you receive a QR code by email within minutes. Open your device settings, select the option to add a mobile plan, and scan the code to install the eSIM profile.
You can install the eSIM before you travel, but it remains inactive until you land in Singapore and turn on data roaming for the eSIM line. Once active, your device connects automatically. If you carry a second SIM, set the eSIM as your data line and keep your home SIM for calls and texts over WiFi or your existing plan.
Staying Connected Across Singapore
Singapore offers dense mobile coverage across the city-state, from the downtown financial district and Orchard Road shopping belt to Sentosa, Changi Airport, and HDB estates in the suburbs. Connectivity on the MRT is reliable throughout the network, including the new Thomson-East Coast Line and older North-South and East-West lines. Coverage extends to green spaces like the Botanic Gardens and MacRitchie Reservoir, though signal may weaken in the densest forest trails.
Most travellers use data for Google Maps, Grab ride-hailing, messaging apps like WhatsApp, and checking hawker centre reviews. Streaming video and uploading photos to social media will consume data faster. A 1GB plan typically covers several days of moderate use, while a week of navigation, messaging, and occasional video calls may require 3GB to 5GB depending on your habits. If you plan to work remotely or stream often, choose a larger data bundle.
Frequently asked questions
How much does an eSIM for Singapore cost?
esimbloom Singapore eSIM plans start at $0.36, with 17 plans to choose from. You pay once for the plan you pick — no roaming fees and no contract.
Do I need an eSIM for Singapore?
Only if you want mobile data without roaming charges. An esimbloom Singapore eSIM is installed from a QR code before you fly, activates on your first connection in Singapore, and is data-only — your home SIM stays in the second slot for calls and SMS, with its data roaming switched off.
Do I get a Singapore phone number with the eSIM?
No. esimbloom plans are data-only, so you will not receive a local phone number, SMS, or voice call capability. You can use messaging apps, video calls, and internet services that do not require a phone number.
When does my data allowance start counting down?
The validity period begins when your eSIM first connects to a mobile network in Singapore, not when you purchase or install it. You can install the eSIM profile before departure and activate it on arrival.
Will my eSIM work on Sentosa and at Changi Airport?
Yes. Mobile coverage in Singapore extends across the island, including Sentosa, Changi Airport terminals, and the Jewel complex. You should have connectivity in arrival halls, baggage claim, and passenger terminals at Changi.
Can I use the eSIM on the MRT and in shopping malls?
Yes. Mobile data works throughout the MRT network, including underground sections, and in shopping malls across Singapore. Coverage is reliable in areas like Marina Bay Sands, VivoCity, and Jewel Changi Airport.
What happens if I run out of data before my plan expires?
Your connection will stop when the data allowance is used up, even if the validity period has not ended. You can purchase an additional plan and install a second eSIM profile if your device supports multiple eSIMs.
