From the best suite in W Sentosa cove, a Marina view clubroom in Marina Bay Sands and the presidential Suite in the Intercontinental to the most historical room in the first luxury hotel in Singapore The Raffels. I have never been disappointed in Singapore but all luxury hotels have a different style.

Planning your trip to Singapore and wondering what is the best eSIM to stay connected? This is my complete guide with everything you need to know before buying an eSIM for Singapore, including my personal recommendation, a comparison of the best Singapore eSIMs, up to date prices and everything you need to know about using an eSIM in Singapore.

After comparing the current available Singapore eSIMs, SimOptions is my top recommendation. They have plenty of Singapore eSIM plans to choose from and they offer an unlimited data eSIM for Singapore for 7 days for ~$15 USD. That makes SimOptions the best eSIM for Singapore in 2026.

I have been to Singapore uncountable times over the years. Sometimes for visa runs from Bali, sometimes as an easy getaway from Kuala Lumpur by direct bus and many times simply because Singapore is one of the most convenient travel hubs in Asia between Indonesia, Malaysia and Thailand. On top of that, I just love the big city life in Singapore.

Most of my visits are short city trips, stopovers or visa runs. That is exactly why I think an eSIM makes so much sense for Singapore. You arrive, you are instantly online and you do not waste time looking for a SIM card shop after landing at Changi Airport or arriving by bus from Malaysia.

Don't waste money on high roaming charges. In this guide I compare the best eSIMs for Singapore, explain why I use SimOptions, show you the cheapest Singapore eSIM alternatives and tell you when a local prepaid SIM card in Singapore might still be a better option.

Find out where and when to order your Singapore eSIM, which eSIM provider has the best value, what to know about unlimited data eSIMs and how to avoid common eSIM mistakes when traveling to Singapore.

Why I use SimOptions as my Singapore eSIM

For my own trips to Singapore I personally use the SimOptions eSIM for Singapore. The main reason is simple: most of my Singapore trips are short. I have been to Singapore uncountable times over the years, but in general my trips to Singapore are about 3-5 days.

Singapore has often been a quick and easy stop for me. I have used Singapore for visa runs from Bali, as a convenient travel hub in Asia between Indonesia, Thailand and Malaysia.

That is also why the 7-day unlimited data eSIM from SimOptions makes so much sense for me and it is just $14.90 USD.

You get unlimited data for 7 days, which is exactly the kind of eSIM I want for a short Singapore trip. I do not have to think about how much data I use, I do not have to look for a SIM card shop on arrival and I am connected as soon as the plane lands at Changi Airport or when I arrive by bus from Malaysia.

Another big reason why I recommend SimOptions is that tourist SIM cards at Changi Airport (SIN) are expensive. Yes, buying a physical prepaid SIM card at Singapore Airport is convenient, but if you only visit Singapore for a couple days, an eSIM is much more convenient and also much cheaper than the tourist SIM cards at Changi Airport.

One thing to know is that SimOptions does not disclose which mobile network their Singapore eSIMs use. Normally I always prefer eSIM providers that clearly mention the network, but in Singapore this is less of a concern. Singapore is a very small country and all 4 mobile internet providers have excellent 4G/5G coverage across the country.

In my opinion, the network is therefore not the deciding factor for choosing a Singapore eSIM. You can expect strong mobile data coverage pretty much everywhere in Singapore.

That said, SimOptions is not automatically the best eSIM for every traveler. If you only need a small amount of data, then Ubigi can be a cheaper option. But if you want the easiest option with unlimited data for a short Singapore trip, then SimOptions is my top recommendation.

Singapore eSIM comparison table

To make it easier I filtered the best eSIM providers for Singapore and compared the most popular Singapore eSIM plans for 2026. The table below shows the best value plans from SimOptions, Ubigi, Airalo, Airhub and Holafly.

For Singapore, the exact mobile network is less important than in bigger countries. Singapore is a small city-state with excellent mobile internet infrastructure and strong 4G/5G coverage pretty much everywhere. Some eSIM providers disclose the network they use, others do not.

Based on this comparison, SimOptions is my top recommendation for Singapore in 2026. The 7-day unlimited data eSIM for ~$15 USD is the best deal for most travelers who want to stay connected without worrying about data limits.

Ubigi is a great alternative if you only need a smaller data package, while Airalo and Airhub are good fixed-data options.

Holafly also sells unlimited data eSIMs for Singapore, but it is much more expensive than SimOptions. On top of that, Holafly uses a Fair Use Policy and hotspot usage is limited, which makes it less attractive for travelers who actually want to use a lot of data.

Best budget eSIM for Singapore: Ubigi

If you are looking for the best budget eSIM for Singapore, then Ubigi is the best option in this comparison. Ubigi has some of the cheapest Singapore eSIM plans and is especially interesting for travelers who do not need unlimited data.

The best value Ubigi eSIM for Singapore is the 10 GB data plan for $11 USD, valid for 7 days. That is a great deal for a short Singapore city trip, stopover or visa run.

For most travelers who only use mobile data for Google Maps, WhatsApp, Grab, browsing, social media and finding restaurants, 10 GB should be more than enough for a couple days in Singapore.

Here are some of the other Ubigi eSIM plans for Singapore in 2026:

• 1 GB data for 7 days = $3 USD
• 3 GB data for 15 days = $6 USD
• 10 GB data for 7 days = $11 USD
• 10 GB data for 30 days = $14 USD
• 25 GB data for 30 days = $24 USD

Click here to check out all the available Ubigi eSIM plans for Singapore.

An advantage of Ubigi is that their Singapore eSIMs operate on the Starhub and Simba 5G network. However, in Singapore I personally do not think the exact network is the most important deciding factor. Singapore is a small country with excellent mobile internet coverage and you can expect strong 4G/5G signal pretty much everywhere.

The main reason why I do not rank Ubigi above SimOptions is simple: Ubigi is cheaper if you only need a fixed amount of data, but SimOptions gives you unlimited data from $14.90 USD. For just a few dollars more, I personally prefer the peace of mind of not having to think about data limits.

That said, if you are a light data user and want the cheapest good eSIM for Singapore, then Ubigi is the best budget eSIM in 2026.

Best unlimited data eSIM for Singapore

If you are looking for an unlimited data eSIM for Singapore, there are two main options in this comparison: SimOptions and Holafly.

On paper both providers offer unlimited data eSIMs for Singapore, but there is a big difference in price, hotspot use and overall value. That is why SimOptions is my preferred unlimited data eSIM for Singapore in 2026.

Holafly vs. SimOptions unlimited data eSIM for Singapore

The price difference is the biggest reason why I recommend SimOptions over Holafly. A 7-day unlimited data eSIM from SimOptions costs $14.90 USD, while a 7-day Holafly unlimited data eSIM for Singapore costs $27.30 USD. That means Holafly is basically double the price for the same validity.

Holafly does mention that its Singapore eSIMs are 5G ready and operate on the Singtel & Starhub network, but for Singapore that is not a major advantage in my opinion. Singapore is a very small country and all mobile internet providers have excellent coverage. You can expect strong mobile data coverage pretty much everywhere in the city-state.

With Holafly, hotspot usage is restricted, which can cause issues if you want to tether your laptop or share data with another device.

Another reason I am cautious with unlimited data eSIMs is the Fair Use Policy. If an unlimited data plan comes with hidden speed restrictions or unclear data limits, it is not truly unlimited in the way travelers expect it to be.

Therefore, my conclusion is simple: SimOptions is the best unlimited data eSIM for Singapore in 2026. It is much cheaper than Holafly, easy to order online and the 7-day unlimited data plan is perfect for short trips, stopovers and visa runs.

Other recommended eSIM providers for Singapore

Apart from SimOptions and Ubigi there are a couple more Singapore eSIM providers worth checking: Airalo, Airhub and Nomad. These providers mostly sell fixed-data eSIM plans, so they are mainly interesting if you already know how much data you need and you do not want an unlimited data plan.

Airalo

Airalo is one of the most well-known eSIM providers in the world and Traveltomtom has used Airalo many times around the world. Their Singapore eSIMs are easy to install and a reliable option if you only need a fixed amount of data.

The best value Airalo eSIM for Singapore is the 20 GB data plan for $22 USD, valid for 15 days.

🎁 Exclusive Airalo discount for Traveltomtom readers: get 20% off with coupon code TT20. Valid until mid July 2026 and only for first-time Airalo users.

Airhub

Airhub is another option for travelers looking for a fixed-data Singapore eSIM. Their 22 GB data plan for $19.50 USD is good value on paper and valid for 30 days.

The Airhub eSIMs for Singapore operate on the Simba network and are data-only. Calls and SMS are not included.

Nomad

Nomad also sells decent eSIM plans for Singapore and Traveltomtom has used Nomad several times around the world. The tests went well and in general Nomad works fine as a budget eSIM provider.

For Singapore, Nomad offers several fixed-data eSIM plans, including:

• 3 GB data for 30 days = $6.50 USD
• 5 GB data for 30 days = $9 USD
• 10 GB data for 30 days = $14 USD

These are decent prices and Nomad also has larger 20 GB and 50 GB plans. However, for Singapore I would not rank Nomad as my first recommendation because Ubigi is cheaper for similar fixed-data plans. For example, Ubigi offers 10 GB data for $11 USD, while Nomad charges $14 USD for 10 GB data.

Is an eSIM cheaper than buying a SIM card at Changi Airport (SIN)?

Yes, in most cases an eSIM is cheaper than buying a tourist SIM card at Changi Airport (SIN), especially if you are only visiting Singapore for a couple days.

The cheapest tourist SIM card at Changi Airport starts at around $25 USD and usually comes with 100 GB data. That sounds like a lot of data, but honestly, who needs 100 GB for a short trip to Singapore?

Most travelers visit Singapore for a stopover, city trip, visa run or a short getaway. For those trips, a SimOptions eSIM for Singapore with unlimited data for 7 days for $14.90 USD simply makes more sense. It is cheaper, easier and you are connected as soon as you arrive.

If you only need a smaller data package, then there are even cheaper Singapore eSIMs available. For example, Ubigi has Singapore eSIM plans from just $3 USD.

A local prepaid SIM card can still be useful if you want a Singapore phone number, calls or SMS. But if you only need mobile data, then an eSIM is the better value option for most short trips to Singapore.

For a full comparison of local SIM card prices, check my complete guide for buying a prepaid SIM card in Singapore.

Should you buy an eSIM or a local prepaid SIM card in Singapore?

For most short trips to Singapore, I recommend getting an eSIM. It is fast, easy and you are connected as soon as you arrive. No SIM card shop, no passport registration and no need to figure things out after a long journey.

A local prepaid SIM card in Singapore is still very valuable if you need a local phone number, calls or SMS. It can also be much cheaper if you stay longer and use a lot of data. For example, a Simba prepaid SIM card can give you 100 GB data for around $10 SGD, which is about $7 USD.

The downside is that you need to find a SIM card shop, bring your passport and register the SIM card in person. That is not a big deal if you are staying in Singapore for a longer time, but for a short city trip, stopover or visa run, I personally find an eSIM much more convenient.

My advice is simple: choose an eSIM for short Singapore trips and convenience. Choose a local prepaid SIM card if you stay closer to 30 days, need a Singapore phone number or want the cheapest possible data package.

When to order and how to activate your Singapore eSIM

You can order your Singapore eSIM any time before your trip. Most eSIMs have to be installed within a certain period after purchase, so always check the provider’s instructions before ordering too far in advance.

My advice is to order and install your eSIM on the day of departure or the day before you travel to Singapore. You need a stable internet connection to install an eSIM, so it is best to do this at home, at your hotel or anywhere with reliable WiFi.

Do not wait until you arrive at Changi Airport to install your eSIM if you can avoid it. Singapore Airport has WiFi, but installing your eSIM before your flight is simply easier. That way you are connected as soon as the plane lands.

Activating an eSIM is very simple. After ordering your Singapore eSIM online, you receive a QR code or installation instructions by email. Scan the QR code, follow the steps on your phone and select the eSIM as your mobile data line.

Make sure data roaming is turned on for your Singapore eSIM. This is normal for most travel eSIMs and does not mean you are using expensive roaming from your home provider.

Things to know before buying an eSIM for Singapore

Before you order an eSIM for Singapore, quickly check the following things:

• Your phone must be eSIM compatible: not every phone supports eSIMs, so check this before ordering. If your phone is not eSIM compatible, an eSIM will not work.
• Your phone must be unlocked: eSIMs only work in unlocked phones. If your phone is locked to your mobile provider at home, you first need to unlock it before using a Singapore eSIM.
• Most Singapore eSIMs are data-only: the eSIMs in this comparison do not come with a Singapore phone number and do not include calls or SMS.
• You can keep your own phone number: you can use your Singapore eSIM for mobile data and keep your SIM card from home active for WhatsApp, calls or receiving SMS verification codes.
• Turn off data roaming on your home SIM: to avoid high roaming charges, make sure your home SIM is not used for mobile data while traveling.
• Turn on data roaming for your eSIM: most travel eSIMs require data roaming to be switched on. This is normal and does not mean you are using expensive roaming from your home provider.
• Install your eSIM with stable WiFi: always install your eSIM when you have a reliable internet connection, preferably before your flight to Singapore.
• Network coverage is not a big concern in Singapore: Singapore is a small country with excellent 4G/5G coverage, so price, data allowance and convenience are more important than the exact network.

For most travelers visiting Singapore in 2026, I recommend ordering an eSIM before arrival. It is the easiest way to stay connected, especially if you are only in Singapore for a short city trip, stopover, visa run or quick getaway from Malaysia, Indonesia or Thailand.

My top pick is the SimOptions eSIM for Singapore. Their 7-day unlimited data eSIM for $14.90 USD is great value, cheaper than tourist SIM cards at Changi Airport and perfect for short Singapore trips.

If you only need a smaller data package, then Ubigi is the best budget alternative. Local prepaid SIM cards in Singapore can still be a good option if you want calls, SMS or a Singapore phone number, but for mobile data only, an eSIM is the easiest and most convenient option.

I hope this Singapore eSIM comparison helped you find the best way to stay connected.

Feeling at home and getting pampered in luxury from the moment you walk in until you check out. The Ritz Carlton Singapore made my stay memorable and made sure I was having a smile on my face constantly. A luxury hotel with a personal touch and the best view of the Marina Bay Singapore. This very exclusive hotel with fantastic views over the bay blew my mind.

It was a kind of a last minute plan to add Hotel Jen Tanglin to my Hotel Tour in Singapore. My flights were flexible and I had two more nights available and so did I end up in the little brother of the Shangri-La Singapore where I stayed as well.

Travelling to Singapore has never been a favourite, although I am pretty intrigued by big cities. My first visit to the country was in 2009 and after that I had never been back. The reason? It is simply too expensive! I am not rich by any means and I think it is not worth spending so much money if for the same money I am spending here in 1 day, I can live a week in the neighbouring countries.

Almost 130 years ago the Raffles Hotel Singapore opened its doors to the public as a 10-room hotel and ever since it is renown as a landmark in Singapore. It was in 1899 when it became the first luxury hotel with electric lights and fans and became a magnet for many international guests. From the beginning of these glorious days in the past until now the hotel is considered as one of the most luxurious places to stay in Singapore.

Best service in Singapore

The Shangri-La Hotel it is all about indulging yourself with pure luxury and excellent service. One of those 5* hotels that never disappoint and always live up to their image. So does the Shangri-La Singapore, voted many times amongst the best hotels in the world and it remains the destination of choice for presidents and diplomats.

My hotel tour in Singapore was not yet complete and I stayed in so many amazing places in this city that I couldn’t believe I was adding another chapter to this great trip. I had never stayed at an Intercontinental Hotel before and I was happy to finally spend some nights in the flagship brand of the IHG Hotels in Singapore. See here more ideas where to stay in Singapore!

With Singapore being one the worlds densest countries it might seem hard to get away from the bustling city. Recently I planned a trip to this city and was looking for the best places to stay in Singapore, but a little bit away from the city. I ended up in W Sentosa Cove on Sentosa Island.
