Singapore eSIM
data from $2.69.

Looking for an eSIM for Singapore? Slashtel offers data only plans from $2.69 that connect automatically to M1, SingTel, StarHub or SIMBA. There is no local number and no calls or texts, but you can use WhatsApp and FaceTime over data. Choose a plan that fits your stopover, business trip or family visit and install it before you fly.

Choosing an eSIM for Singapore

What matters most is that your eSIM works on Singapore's main networks, gives you enough data for your trip, and is installed before you leave. When readers ask what is the best eSIM for Singapore, the answer depends on their travel style. For a short stopover, a small plan with a few days validity is enough. For a longer stay, pick a plan with more data and a longer validity. Check that your phone supports eSIM and that the plan covers the networks you need. Slashtel eSIMs connect to M1, SingTel, StarHub and SIMBA, so you get coverage across the country. Hotspot is included, so you can share data with a laptop or tablet. Installing before you fly means you land connected and avoid hunting for Wi Fi at the airport.

Plans and prices for Singapore

Slashtel offers six data sizes and three validity periods, with prices starting at $2.69. The table below shows the available combinations. All plans are data only and include hotspot use. The price you see is the live price for that plan.

Not every size is available for every duration; the table shows the standard pairings. If you need a different combination, check the checkout page for current options. Prices are in USD and include the data allowance for the validity period. For a one week trip, the 1GB plan for 7 days is often enough for light use. For two weeks, the 3GB plan for 15 days gives more flexibility. For a month, the 3GB plan for 30 days or larger sizes are available.

Networks and coverage in Singapore

Your eSIM connects automatically to M1, SingTel, StarHub or SIMBA, so you get reliable coverage in cities and towns. Singapore has widespread mobile coverage, and these four networks cover the main areas including Changi Airport, downtown, Sentosa and major business districts. The eSIM picks the strongest signal automatically; you do not need to choose a network manually. 5G is available on compatible phones where the network supports it. Coverage can vary indoors, in basements and on the MRT underground sections, but overall you can expect to stay connected throughout your trip.

How much data you need

Most travellers need between 1GB and 5GB for a short trip, while longer stays or heavy users may want 10GB or more. Data use depends on how much you stream, navigate and share. Here are typical trip types with suggested sizes from Slashtel's plans:

• One week: 1GB for 7 days suits light browsing, messaging and maps.
• Two weeks: 3GB for 15 days gives more room for photos and social media.
• One month: 3GB for 30 days works for occasional use; consider 5GB or 10GB if you stream or work remotely.

If you plan to use your phone as a hotspot for a laptop, or if you upload lots of photos and videos, choose a larger plan. Business travellers who attend video calls should pick 10GB or more. Family visitors staying with relatives may use less data if they have Wi Fi at home, but a few GB provides a safety net.

Install it before you fly

Install your eSIM before departure so you land connected and avoid setup stress at the airport. Installation takes a few minutes and requires an internet connection. You can install it at home over Wi Fi. After installation, the eSIM sits in your phone ready to activate when you arrive. Follow the step by step guide for iPhone and Android at /guides/install-esim-iphone-android. If you are unsure whether your phone supports eSIM, check /guides/is-my-phone-esim-compatible. Remember that the eSIM is data only, so you will not get a local phone number. Keep your home SIM in the phone for calls and bank codes, and use the eSIM for data.

Calls, texts and your home number

The Singapore eSIM is data only: there is no local number, and you cannot make traditional calls or send SMS. However, you can use WhatsApp, FaceTime, Skype and other apps that work over data for calls and messages. Keep your home SIM active for important calls and for receiving bank verification codes. To avoid roaming charges on your home SIM, disable data roaming on it and set the eSIM as your data line. Your home number stays reachable for calls and texts, but you should check your home operator's roaming rates. The eSIM itself does not provide a phone number, so you cannot receive SMS to it.
