My recommendation
Traveltomtom recommends buying a Simba sim card for Singapore in the city center. They have the cheapest prepaid sim cards for Singapore and they have a great 4G/5G network. You can get a sim card for less than $10 with 100 GB data.
Buying a prepaid sim card at Changi International Airport Singapore is also possible, but at different rates, expect to pay tourist prices. Expect to pay a minimum of $25 USD.
But Traveltomtom's first recommendation is an eSIM for traveling to Singapore. There is already a SimOptions eSIM for Singapore with unlimited data for just $14.90 USD.

Why buying a sim card for Singapore
First off to avoid high roaming costs. Don't let your trip get ruined by excessive high roaming costs. Some operators charge up to $3 USD for 1 MB data that means opening Instagram will cost you $100 USD. And this is not a joke!
Also don't be fooled by overseas data roaming plans that make you pay $10 USD per day for unlimited data. Did you read the fine print? Unlimited data at what speed? Yes, there you go!
Overseas data roaming plans often cap the data speed. Can you still handle 3G?
There is already a SimOptions eSIM for Singapore with unlimited data for just $14.90 USD. Just saying...
Staying connected makes traveling to Singapore so much more convenient. Think about ordering a taxi through an app or using Google Maps for getting directions, finding nearby restaurants, stay in touch with friends, use your banking apps for online payments, emergencies, etc.
There are so many good reasons for having data on your phone when traveling to Singapore.
As a full time world traveler trying to visit every country in the world I change countries all the time and therefore I always need to find the best way to stay connected. It is one of the first things I do when planning my next trip.

Mobile internet operators
For a small country like Singapore there are a lot of mobile internet providers. In total there are 4 main mobile internet operators in Singapore: Simba, M1, Sing Tel and starhub. All of them sell prepaid sim cards for tourists and you can buy them in one of their retail stores.
As of February 2025 the mobile internet operators in Singapore only provide physical prepaid sim cards for tourists, eSIMs are not available.
Registration process prepaid sim cards Singapore
For buying a prepaid sim card in Singapore you need your passport. A copy of your passport page will be taken in the store for the registration. Your new Singapore sim card will be registered on your name and your passport number. You will receive a physical prepaid sim card with a phone number starting with +65.
You can NOT opt for an eSIM as all the mobile internet providers in Singapore only offer physical prepaid sim cards for tourists as of February 2025.
If for some reason you want to avoid this then either order an eSIM for Singapore on the internet or buy an international physical prepaid sim card for Singapore. There is no ID verification needed for these type of sim cards and you will get connected in Singapore without any form of identity registration, just your email address.
Where to buy a sim card for Singapore
If you decide to buy a local prepaid sim card in Singapore then you can either buy a sim card at Changi International Airport on arrival or get a Singapore sim card in the city.
Below I will tell you in detail everything you need to know for buying a sim card at Changi International Airport. However, the convenience of getting connected straight on arrival comes at a price. Prepaid sim card deals at Singapore Airport are much more expensive than in Singapore city center. Expect to pay tourist prices at Singapore Airport.
Phone Stores
Therefore if you are looking for the best prepaid sim card deals for Singapore then you will have to buy your prepaid sim card in the city center in a phone store.
There are plenty of official retail stores from all the mobile internet operators across Singapore. If you go to any of the bigger shopping malls you will find Simba, M1, Sing Tel and starhub without any problem. Or simply use Google Maps to locate the nearest sim card shop next to your hotel.
Convenience stores
There is also the possibility to buy a local prepaid sim card in a convenient store. These options are especially handy late at night or on Sundays when some phone stores are closed. However, keep in mind that when buying a prepaid sim card in for example 7Eleven you will need to register and activate your sim card yourself.
Online
As mentioned before the easiest way to stay connected when traveling to Singapore in 2025 is by ordering a sim card for Singapore on the internet. If your phone is not eSIM compatible then you can order a physical prepaid sim card for Singapore via SimOptions.
If your phone is eSIM compatible then Traveltomtom recommends ordering an eSIM for Singapore.

Best 4G/5G network in Singapore in 2025
For determining the best prepaid sim card for traveling in Singapore Traveltomtom also looked at the mobile internet coverage and compared the 4G/5G network coverage maps of starhub, M1, Simba and Sing Tel.
Is there 5G in Singapore?
Yes, there is 5G in Singapore. The 5G network in Singapore is probably one of the most advanced ones in the world. Pretty much everywhere you go there is a 5G signal and all the tourist attractions in Singapore are covered with a 5G signal.
However, the catch is that not all mobile internet operators in Singapore allow prepaid sim cards for tourists to use the 5G network, so always ask this when buying a prepaid sim card in Singapore.
Simba 4G/5G network coverage maps
M1 4G/5G network coverage maps
Starhub 4G/5G network coverage maps
Sing Tel 4G/5G network coverage map
Although the above mobile data network coverage maps are updated for 2025 they are not 100% accurate. However, they are a great reference to compare the 4G/5G networks of the mobile internet providers in Singapore in 2025.
When comparing the above 4G/5G network coverage maps of the mobile internet operators in Singapore we can come to the simple conclusion that it doesn't matter so much which prepaid sim card you buy. All of the mobile internet providers in Singapore have a more than excellent 4G/LTE network all across the country.
Singtel used to be ahead of starhub, M1 and Simba, but it looks like in 2025 they all caught up and all mobile internet providers in Singapore have an excellent network in 2025.
Best prepaid sim card for Singapore in 2025
One of the conclusions after comparing the prepaid sim card deals for Singapore is that buying a sim card at Changi Airport is much more expensive than buying the exact same prepaid sim cards for tourists in a phone store in Singapore city center.
So if you want the cheapest prepaid sim card deals you have to wait until you get to the city and go to a phone store.
However, buying a prepaid sim card on arrival at Singapore Airport is more convenient and the shops are open 24 hours.
But when comparing eSIMs for Singapore with the prepaid sim card deals at Singapore International Airport then you are better off with an eSIM you order online.
At Singapore Airport a Singtel sim card with 100 GB data is $70 SGD ($51 USD) and in Singapore city center you pay for the exact same sim card $30 SGD ($40 USD).
But an a SimOptions eSIM for Singapore with unlimited data is just $14.90 USD. I mean it is an easy choice right?
Traveltomtom recommends ordering an eSIM for Singapore check my comparison of the best eSIMs for Singapore in 2025.
All mobile internet providers in Singapore have an excellent 4G/LTE network and therefore when comparing the prices Traveltomtom concludes that SIMBA is the best prepaid sim card for Singapore for tourists in 2025.
If you buy a prepaid sim card in a Simba phone store in the city center you can find a prepaid sim card deal with 100 GB data + unlimited minutes/calls for 30 days for just $7 USD.
Unfortunately Simba prepaid sim cards are NOT sold at Changi International Airport and they are only available for tourists as physical prepaid sim cards and not as eSIMs.

How to get from Singapore Airport to the city center
Check the above information sheet for getting to the city center from Changi Airport. However, my prefered way getting from the airport to Singapore center is an Uber/Grab.
