eSIM Singapore: Mobile Data for Stopovers and City Stays
Whether you have a day between two flights or a week of meetings, Singapore is a place where you want your phone online from the start. An eSIM Singapore data plan from Anosim gives you mobile internet without a local SIM card. Singapore has a specific order, though: you buy at home and install the eSIM only after landing. Below you find the sequence, the 90-day activation limit, hotspot use and how to receive SMS codes.
Stopover, business trip or city break: an eSIM for every stay
Singapore is often a short stop. On a layover of a day or two, a Singapore eSIM saves you from buying a local SIM card that you will hardly use. On a business trip you can answer emails and join video calls between appointments, and on a city break maps, ride apps and restaurant bookings run on mobile data.
Singapore lies outside the EU roaming rules, so a European tariff can make every megabyte expensive. With a prepaid travel eSIM in Singapore you know your costs before you fly, and your regular SIM card can stay in the phone so your usual WhatsApp number remains reachable.
The Singapore sequence: buy at home, install on arrival
For Singapore the eSIM is installed and switched on only after you land. Here is how the steps divide between home and destination:
Before departure
Check that your phone is eSIM-capable and not locked to a carrier. Buy the plan, paying from your Anosim balance. The QR code is then stored in your account under My eSIM Plans. Leave it unused for now.
After landing
Connect to Wi-Fi, because the phone needs internet to install the profile. Scan the QR code once; it cannot be used a second time, and the profile should not be deleted afterwards. Then switch the eSIM on, select it for mobile data and allow data roaming for it. It typically registers with a local network within one or two minutes.
If the eSIM does not connect
Restart the phone, turn airplane mode on and off, and set the network selection to automatic. If that does not help, write to our support on Telegram, in the website chat or by email, around the clock.
Timing your purchase: 90 days to activate
A plan for Singapore must be activated within 90 days after you buy it. For many other destinations that window is 180 days, so do not buy months in advance for a trip that is still far off.
The days of your plan do not start at purchase. They start with the first connection to a supported network in Singapore. If you buy two weeks before departure, you lose nothing.
Coverage across the city-state
Coverage is listed for Singapore. As a tourist eSIM for Singapore, the plan is made for what visitors do in the city: navigation, translations, ride bookings, messengers and uploads.
The network can be 3G, 4G/LTE or 5G, depending on the operator and the exact location. If you use a lot of data, the operator's fair-use rules may slow the speed. Large downloads are easier on the hotel Wi-Fi.
Hotspot for laptops and travel partners
Hotspot is available with the Singapore plans. On a work trip you can put your laptop online without searching for a café network, and when travelling as a couple or family one plan can serve a second phone or a tablet.
All connected devices take their data from the same plan, so a busy hotspot empties it faster.
Bank, booking or app codes: SMS without a number on the eSIM
A data eSIM has no phone number. If your bank, an airline or an app sends a verification code by SMS while you are in Singapore, it cannot arrive on the eSIM. An Anosim number takes care of it:
- Activation for one code, such as a single sign-up.
- Rent Service for a service that will verify you again.
- Rent Number for one number that works with all services.
If a number is virtual, it is labelled as such in the provider selection.
Across the causeway and beyond
Many trips continue from Singapore to Malaysia, Indonesia or Thailand. Each country has its own plans in the order form, and regional plans are listed there too. See eSIM Malaysia, eSIM Indonesia and eSIM Thailand. Which plan is the best eSIM for Singapore depends on your device and route; all destinations are on the eSIM page.
