Best Singapore SIM Cards for Tourists: 2024 Detailed Guide

Buying a SIM card to prepare for a Singapore trip is needed to stay connected during the trip. You still need to contact your own world: family back home, friends or relationships on internet platforms. Because roaming fees are high and free WiFi is not stable, prepaid Singapore SIM cards will be a perfect alternative.

 Below we will persuade you why this is the best choice for your abroad journey.  

I. Should You Get a SIM Card in Singapore ?

YES. While traveling outside your home country, you have to pay attention to a fee called roaming charges. They are additional fees incurred when a mobile phone user connects to a foreign network. These charges apply to voice calls, text messages, and data usage, often resulting in higher costs compared to domestic rates.

Then, let’s take a simple math calculation: 

Roaming charges would set you back about $10 a day, depending on your current mobile network operator. So, for example, your 5-day trip would have cost $50 for contacting.

But a SIM card with a basic calling plan in Singapore costs just $5 per day and you can text messages, call within Singapore and use WiFi.

Many travelers are doing the math when they plan international trips. They’re weighing the convenience of a calling plan against the savings of a SIM card. So when should you use a SIM and when should you use a calling plan? And are they your only options? 

Here are some ways to stay in touch when you pay a trip to Singapore: 

RoamingUse the current SIM to roam and connect to the Singapore network.HIGH:Higher costs, including additional fees and charges.MEDIUM:Depend on your operators. VARIES: Depend on your home network and agreements with local carriersMEDIUM:Not all network operators in your home country have connection and cooperation contracts with Sing network operators
SIM cardsUse a tourist SIM from your local countryMODERATEHave many options with different data and credit for your requirementsHIGH: Use local mobile networks, ensuring a stable and consistent connectionWIDE:Offer extensive coverage as they use local networks, allowing you to stay connected in various locationsHIGH: Be easy to obtain and use. 
Free wifiUse public Wifi in Singapore such as cafes, restaurants, malls,…FREE:Free but limited, and some places may require purchasesLOW: Be available in certain places, but it can be unpredictable and may not cover all areasLIMITED: Be limited to specific areas like cafes or tourist spots.LOW:Require to search for hotspots, and the connection may not always be seamless.

Pro Tip:

  • If you want to call without being afraid of running out of credit, SIM Card is an option for you. You just need to buy a SIM card and insert it in your current phone. This will give you a Singapore number and the same local rates Singapore.
  • If you don’t need to be online all the time, you can consider the free-Wifi option but remember that some public places also need to pay for wifi.

II. Types of Singapore SIM Cards for Tourists

Simply, we can split SIM cards into two types: prepaid Singapore SIM cards and Singapore eSIMs. Both of them also provide two choices: “data-only” option and “data with voice and text” option.

types of singapore sim cards

1. Prepaid Singapore SIM Cards

  • A new physical SIM card will be inserted into the phone. This allow travelers to have a new phone number and connect into singapore network 
  • Advantages: Have various options with affordable prices as prepaid SIMs are widely supported. 
  • Disadvantages: 
    • Risk of losing or damaging the main SIM card and travelers may need to purchase a replacement. 
    • Furthermore, one phone only uses one SIM, (if the phone has one SIM card slot)

2. Prepaid eSIMs

  • eSIM is a digital SIM profile that is embedded directly into your device. No physical SIM card is needed.
  • Advantages: 
    • You can easily connect to multiple carriers and plans directly
    • Quick and convenient to set up since there is no waiting for a physical SIM to arrive or inserting it.
    • Use 2 SIMs at the same time (or 1 physical +1 eSIM or 2 eSIMs The main SIM remains on the phone, no need to remove it.
    • You can install multiple plans/packages on the same phone, but you are only allowed to activate 1 or 2 packages at a specific time depending on the device type as mentioned above.
  • Disadvantages: Devices must be compatible. Not all phones support eSIMs yet.

► Our recommendation: If you have a mobile device which is compatible with eSIMs, choose this option. eSIM includes all advantages and also upgrades many functions to solve the drawback of physical SIM cards. See a detailed list of eSIM equipped devices.

III. Where to buy a Singapore SIM Card for Convenience and Cheap Price? 

We recommend 04 ways you can find a SIM card which is up to your requirements: 

1. Before departure

  • Buy at physical stores that provide travel SIM cards
  • Or order online on websites selling travel SIM cards, wait for the delivery person to come to your home.

Note: For this method, you must prepare the SIM removal tool yourself.

2. At airports

  • Every international airport can offer these cards. The price including prepaid calling credit and data is often at $15-30, more or less. 
  • A caution you need to keep in mind is SIM cards sold at airports are always more expensive from 20% to 30% compared to those sold in the city center. The option to choose is also limited. 

Note: Pay attention to opening and closing time as stores at these airports don’t open 24/7.

3. In convenience stores, supermarkets or gas stations after arrival 

  • Some popular brands are Walmart, Walgreens and 7-Eleven. 
  • But in these places you have to activate the SIM card by yourself. Consider carefully before buying in these stores.

4. Through online

  • You can choose prestigious online websites that provide travel SIM for tourists. They have prepaid physical and virtual one. Online stores like Gigago, Amazon, Best Buy and Walmart are good places for your search.
  • But you must have an address for delivery. 

► Our recommendation:

Among these ways, buying online before departure is the most convenient, because  you will be more proactive with your plans and don’t need to worry about language barriers.

Besides some popular ways (such as portable wifi, roaming, physical SIM cards) to keep in touch with others while traveling, eSIM has emerged as a perfect alternative to the inconveniences of the above forms thanks to scientific and technological advances. 

Below are some superior benefits of eSIM that you should take consideration: 

  • Convenient for installation: With eSIM, you just need a QR code to get one. No need to disassemble. Therefore, no risk of losing the main SIM
  • Easier to switch networks: Instead of inserting a new SIM into your phone, you can switch to a different network quickly as up to five virtual SIM cards can be stored on one eSIM at a time. You also won’t need to go hunting for a SIM ‘ejector tool’ to remove the old SIM from your phone.
  • Have more than one SIM: eSIMs also offer the same advantages as dual-SIM phones with two slots for traditional plastic SIMs, the most obvious being that you can have two phone numbers on one device.

And if you are wondering which supplier can provide quality and reliable eSIMs for your trip to Singapore, we recommend Gigago as the No.1 eSIM service provider based in Hong Kong. Gigago offers a unique range of data-only and combined data & call credit plans, which start from a 5-day plan with 1GB per day for $5. They also have 7-day, 15-day, and 30-day plans ranging from 1GB to 50GB of total data, or 1GB to 3GB per day, with prices from $5 up to $89.50.

Besides competitive price, choosing Gigago Singapore eSIM, you can reap the following additional benefits:

  • Easy online purchase and activation process.
  • Multiple payment options, including PayPal.
  • 24/7 customer support via chat and email.

Pro Tip: You should analyze your data needs and choose the Gigago eSIM plan that fits you best. Remember, data-only plans are cheaper but require separate calls (Wi-Fi calls or local SIM for outgoing). Data & call credit plans offer convenience but might be slightly more expensive per GB.
