Prepaid SIM Cards for Singapore: A Complete Guide

Prepaid SIM Cards for Singapore

Do you plan to visit Singapore and wonder how you can get a hold of a good SIM card?

Singapore is a tech-savvy nation with plenty of operators and products in the market. As such, we have written this article to give you a helping hand and to present some of the best options possible.

Some readers faulty believe that one has to buy a SIM card once arriving in Singapore. That’s not necessarily the case as you can pre-order SIM cards online, get them sent to your home before you depart, or get an eSIM card.

Finally, there are some other interesting options like renting a phone for your trip to Singapore.

Types of SIM cards with data for Singapore

Generally speaking, you can access data connections in Singapore in four different ways. You can either purchase a local prepaid SIM card, use roaming with your current subscription in your home country, get an eSIM, or buy an international travel SIM card. Let’s review the options.

1. eSIM (recomended)

If you don’t need to make any local calls and only want internet access on your cellphone. The eSIMs (electronic SIM cards) are probably one of the cheapest and most convenient options.

You only need to install their software on your cellphone, choose a data plan and you will have internet access as soon as you arrive in Singapore (or any other country included in the plan).

2. Local Prepaid SIM Cards

A popular and easy option is to buy a local prepaid SIM card. It’s so convenient just to drop by a shop just when you’re still inside the airport.

Besides, if you want an even more convenient experience you can just order a SIM card online before you depart for Singapore. There are plenty of websites, such as Amazon, that offer SIM cards for reasonable costs.

Just keep in mind that you need to activate the SIM card before you travel, you’ll need your passport to activate the card as well.

3. International Travel SIM Cards

The international travel SIM cards are useful for travelers who plan to visit multiple countries during their trip to Asia. Might you be a backpacker or a business person who needs to meet with local clients in various countries, then this can be a good option.

Even if the prices are generally reasonable, it’s a bit more expensive to use international travel SIM cards for local dittos. We will go into greater detail and present the prices from various service providers later in this article.

4. Roaming

Some travelers decide to use their roaming while traveling overseas. This is sometimes the case for executives who are employed by a multinational company and that are covered financially.

Some travelers use roaming if they don’t have a local SIM card and are in great need of using the internet. That said, there are also service providers who offer comparably low roaming costs. Yet, this option is the least preferred and often the most expensive one.

However, I also want to mention that Singapore is a developed country and they even have public Wi-Fi in most parts of the downtown area. The Wi-Fi is called Wireless@SG and is a free public Wi-Fi, you’ll find hotspots at many locations, including everything from malls and museums to MRT stations and public libraries.

To use the Wi-Fi, you need to be able to receive text messages internationally as they will send you a password code. You can find a list of hotspot locations by visiting this article.

Buying local SIM cards picked up at the airport

As mentioned above, a convenient option is to either pre-order a SIM card and pick it up at the Changi airport, or simply buy one directly after you have arrived at the airport.
Redtea Mobile, for example, allows you to pre-order the SIM card and do just that.

One product available is the M1 4G Prepaid Sim Card, which can only be picked up at Changi Airport. The service has received more than 25,000 reviews with an average rating of 4.7, which speaks for itself.

International Travel SIM cards

If you plan to visit several different countries during your trip you should consider to opt-in for a so-called international travel SIM card. The benefits of using an international SIM card is that you can stick to one SIM card, avoiding the hassle to buy a new one every time.

As shown above, you can find international travel SIM cards from AIS on Amazon that come at reasonable costs. As explained in our article about prepaid SIM cards in China, there are plenty of operators that offer SIM cards which can be used all over the world.

The price for this kind of SIM card is a bit more expensive though.

Roaming in Singapore

As mentioned, using roaming is probably your worst option as it often results in higher costs.

Even if there are operators who offer roaming as a part of their package, you will most likely end up with a larger phone bill if you use roaming via your regular subscription back home.

Truth be told, it’s better to use public Wi-Fi in Singapore, which is accessible are numerous hotspots (at least if you stay for a few days).

Also, make sure whether your operator allows you to use roaming.

Rent a phone in Singapore

This is the final option I will present in this article. There’s one service provider who stands out in the phone-rental market, namely Cellular Abroad. Founded in the US in 2001, they help US and Canada-based persons to rent a phone and to get a SIM card before departure.

Renting a phone might not be as useful if you visit China where the issues with cybersecurity are more prevalent. That said, there are some benefits to using a rental phone.

  • 1 week: USD 56
