If you're flying from the UK to Australia, or from India to the UK, Singapore is a common stopover. You land at Changi, you have 12 to 48 hours, and you want to find a hawker centre, check your messages, and get your bearings. A Singapore eSIM means you have data from the moment you switch off airplane mode.
For India-origin travellers, this is also a chance to catch up with family over WhatsApp video without worrying about roaming costs. And if you're keeping an Indian SIM active for bank OTPs, the eSIM slots in alongside it on your dual-SIM phone.
For a short stopover, data needs are modest. Here's a rough guide:
| Trip length | Data plan | What it covers |
|---|---|---|
| 1 day (layover) | 1GB | Maps, WhatsApp, light browsing |
| 2-3 days (stopover) | 3GB | Maps, WhatsApp video calls, some streaming |
| 4-5 days (extended) | 5GB | All of the above plus regular video streaming |
Maps use about 5MB per 10 minutes of navigation. A 10-minute WhatsApp video call uses roughly 25MB. Streaming a 30-minute show on Netflix in standard definition uses about 250MB.
If you're staying longer, our Singapore eSIM plans go up to 10GB. Prices start from $X.XX for 5GB over 30 days.
Arrival at Changi. Changi has free Wi-Fi, but it requires registration with a local number or passport details. That's a hassle when you've just landed. With an eSIM installed, you're online before you hit the immigration queue.
Hotspot and SIM management. You can use your Singapore eSIM as a hotspot for a laptop or tablet. On iPhone, go to Settings > Cellular > Your eSIM > Personal Hotspot. On Android, look for "Hotspot & tethering" in the network settings.
If you're keeping an Indian SIM for OTPs, make sure your phone is set to use the eSIM for data. On dual-SIM phones, this is in the network settings — select the eSIM as the data line. Your Indian SIM will roam in Singapore, which is fine for receiving SMS OTPs.
Buy the eSIM, scan the QR code, and install it while you're still on Wi-Fi at home. It activates automatically when you connect to a network in Singapore. The whole process takes about two minutes. If you're not sure your phone supports eSIM, check our installation guide.
Our Singapore eSIM uses a major UK network's roaming partner, so coverage is solid across the island, including the MRT and Sentosa. No contracts, no hidden fees, and a refund if you don't use it.
If your phone is unlocked and supports eSIM (iPhone XS or later, most recent Android devices), yes. Check our compatibility guide before buying. The eSIM connects to a major UK network's roaming partner in Singapore, so you get coverage as soon as you land.
For a 2-3 day stopover, 3GB is usually enough if you use maps, WhatsApp, and light browsing. If you plan to stream video or use video calls, go for 5GB or more. You can always top up, but buying a larger plan upfront is cheaper per GB.
Yes. Install the Singapore eSIM for data and keep your Indian SIM active for bank OTPs and SMS. On dual-SIM phones, set the eSIM as the data line and the Indian SIM for calls and texts. Your Indian SIM will roam in Singapore, which is fine for OTPs.
Usually, yes, for short stays. A local SIM at Changi costs around SGD 12-15 for 10GB. Our 5GB plan for 30 days is priced from $X.XX and you avoid the queue at the airport. You also get it delivered instantly by email, so you can install before you fly.
Nothing to worry about. The eSIM activates when you first connect to a network in Singapore, not when you land. If your trip is delayed by a few days, your plan still has its full 30-day validity from first use.
No. A Singapore eSIM only works in Singapore. If your stopover includes another country, consider our Europe+ plan or a separate eSIM for that destination. Check our destinations page for coverage.
