Singapore travel data eSIM
What is a Singapore eSIM?
Arriving in Singapore, you can skip the hassle of local SIM cards. This eSIM connects you to M1 5G network upon landing at Changi or exploring Marina Bay. It provides immediate mobile data access for navigation, translations, and transit apps. Whether you are crossing the causeway or visiting the southern islands, stay connected for bookings and maps. The plan installs via QR code before your flight, ensuring you are ready to explore the city-state without searching for Wi-Fi.
Your Singapore eSIM connects to the SingTel 5G network. This single-network connection handles your data needs for daily activities like ride-hailing and digital ticketing. The plan validity begins when you first connect to the network at your destination. You choose from several data allowances, ranging from 1GB for short visits to 20GB for extended stays, all valid for up to 30 days depending on the specific tier selected.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which network does the Singapore eSIM use?
The eSIM connects to the SingTel 5G network. This means your data traffic routes through this specific operator's infrastructure. Connectivity availability depends on where SingTel maintains its network presence within the country, so local conditions determine your actual experience.
Does this eSIM work in Malaysia or Indonesia?
No, this is a single-country plan valid only in Singapore. It does not extend to neighbouring territories like Malaysia or Indonesia. For trips spanning multiple countries, you should look for our regional plans designed for multi-country travel.
Which plan size fits a trip to Marina Bay and Sentosa?
For a typical visit covering Marina Bay and Sentosa, the 3GB or 5GB plans are often sufficient as a rough guide. Heavier usage, such as constant video streaming or large file downloads, might require the 10GB or 20GB options to avoid running out of data.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
