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.

How much data for this trip?

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 $2.49 for 5GB over 30 days.

Two practical notes for Singapore

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.

Install before you fly

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.

Questions, answered

Will a Singapore eSIM work on my UK phone?

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.

How much data do I need for a Singapore stopover?

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.

Can I keep my Indian SIM for OTPs while using a Singapore eSIM?

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.

Is the Singapore eSIM cheaper than buying a local SIM at Changi?

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 $2.49 and you avoid the queue at the airport. You also get it delivered instantly by email, so you can install before you fly.

What happens if my flight is delayed and I arrive later than planned?

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.

Can I use my Singapore eSIM for a layover in another country?

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.

What is the best eSIM for Singapore?

For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Singapore is $5.79 on M1, SingTel and StarHub. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.

Do I need a Singapore SIM card or an eSIM?

If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.

How much does an eSIM for Singapore cost for a week?

From $2.49 for 1GB valid 7 days, as of 9 October 2026. Longer trips: two weeks from $3.69 (3GB), one month from $3.89 (3GB).

What is the cheapest data per GB for Singapore?

$0.59 per GB on the 50GB plan (30 days, $29.39). Bigger plans usually cost less per GB, so buy the size you expect to use.

Which networks does a Singapore eSIM use?

M1, SingTel, StarHub and TPG Telecom, with speeds up to 5G where available. The eSIM picks the strongest network automatically.

Does the Singapore eSIM include a phone number?

No. Slashtel eSIMs are data only, with no local number, calls or SMS. WhatsApp and other internet calls work, and your home SIM can stay on for calls and OTP texts.

When does the Singapore eSIM start counting days?

Validity starts when the eSIM first connects to a network in Singapore, not when you buy it, so you can buy and install it before you travel.

How do I install the Singapore eSIM?

After payment Slashtel emails a QR code within a minute. Scan it in your phone settings while on Wi-Fi at home, then switch on data roaming for the eSIM when you land.

Will my phone work with a Singapore eSIM?

Your phone must support eSIM and be carrier-unlocked. Dial *#06#: if an EID appears, the phone supports eSIM.

Can I use hotspot with the Singapore eSIM?

Yes. Hotspot and tethering are allowed on Slashtel eSIMs.
