Singapore: Best Tourist eSIMs Reviewed (2024)

If you are a seasoned traveler like me, then you understand the thrill of exploring new destinations and the importance of staying connected while on the go. Singapore, with its vibrant culture, stunning attractions, and bustling city life, is a must-visit for any globetrotter.

As someone who has experienced the wonders of Singapore firsthand, I know how crucial it is to have a reliable eSIM to stay connected with loved ones and navigate the city with ease, especially since roaming is expensive and you need Google Maps on every twist and turn on the city streets. 

In this guide, I will share my insights and review the best tourist eSIMs available in Singapore for 2024, ensuring that your trip is not just memorable but also seamlessly connected. Let us dive into the world of eSIMs and discover the perfect one for your Singapore adventure!

The Future of Travel: Rise and Benefits of eSIMs

I am one of the few who saw and started reaping the benefits of digital SIM cards from their beginnings. There are many benefits of using them over a physical SIM card. First of all, you do not have to look for a physical store to buy a SIM card from. Another advantage is the ease of switching between mobile plans or carriers without needing to swap physical SIM cards. This can save time and hassle, particularly when traveling internationally or seeking better data plans. The eSIM activation is pretty straightforward too, with some providers only giving you a QR code to scan. 

Usually, phones that support eSIM technology have dual SIM functionality, allowing you to use both your eSIM and a physical SIM card simultaneously. This flexibility is especially valuable for travelers or those managing multiple phone numbers. Additionally, when you activate data roaming, eSIMs can provide seamless connectivity wherever you go, making them an even more valuable asset for modern travelers.

Airalo eSIMs for Singapore

Airalo has three types of eSIM that can be used solely in Singapore or include the country:

  • Connect Lah!: Can be used only in Singapore;
  • Asialink: Used in 14 Asian countries, Singapore included; 
  • Discover(+): One of my favorite eSIMs and used in 130 countries worldwide (a bit pricier than the rest, but totally worth it);

Connect Lax! has six options to choose from with the Singapore/Connect Lah! 1 GB eSIM for 7 days, costing 4.50 USD being the most popular one. The eSIM works best with the Singtel network on your mobile phone. For more information about Singaporean network providers, check out my Singapore SIM card buying guide

The old Asialink eSIM came with an unlimited mobile data plan, but you only got about 4 GB of high-speed, stable internet connection before it went down to 128 Kbps (painfully slow, I know). Nowadays, the eSIM has six options to choose from, with the Asia/Asialink 5 GB eSIM for 30 days, costing 20 USD being the most popular. Once again, the most reliable network operator for this eSIM is Singtel. If you want to check out Asialink eSIM in depth, check out my ongoing review, as I have tested the eSIM in eight countries so far.

When I first started using Discover, I felt it could improve. And my prayers have been answered, as nowadays, Discover is as good as it gets! And although it improved greatly, its prices remained the same. There are twelve variants of the eSIM to choose from, with users opting for Discover 20 GB eSIM for 365 days, costing 69 USD the most. The eSIM works best with Singtel, and if you want to take an in-depth look at one of my (so far) favorite eSIM cards, check out my ongoing Airalo Discover+ eSIM review.

Alosim eSIM for Singapore

Alosim, supported by AffinityClick, is making significant strides as an emerging eSIM provider. This is mostly because it is been expanding its eSIM options and offerings. At the moment, Alosim offers only one eSIM for Singapore, and it solely works within the country. 

There are five options to choose from, with the Singapore 1 GB eSIM for 7 days, costing 6.50 USD being the most popular of them all. The eSIM works best with StarHub network provider. As I mentioned previously, if you want to learn more about the performance of these mobile operators, you can take a look at my Singapore SIM card purchasing guide. In it, I delve into the coverage and speed capabilities of each SIM card.

Holafly eSIMs for Singapore

Alongside Airalo, Holafly is one of the most popular eSIM providers. 

It gained recognition in June 2022 by introducing unlimited data plans, a rarity at the time. While the availability of unlimited data eSIMs has increased among various providers today, Holafly has stood out by expanding its unlimited data service from initially covering 45 countries to encompassing nearly 100 nations by 2023, with ongoing additions even in October of that year.

Initially, Holafly's Asia eSIM offered limited data usage, providing 6 GB for 15 days at 44 USD and 10 GB for 30 days at 54 USD. Although these plans might seem reasonable, there was a catch: you could only use a maximum of 500 MB of data per day, which could be limiting for some users.

After many, many complaints (mostly mine and Phone Travel Wiz loyal readers), Holafly introduced an unlimited data option for Asia. How I love it when companies listen to their clients’ feedback!

Holafly has two eSIMs that can be used in Singapore: 

  • Singapore: used only locally;
  • Asia: used in 11 Asian countries, including Singapore;

The Holafly Singapore eSIM provides users with unlimited internet access for 5-90 days, depending on the chosen package. Speaking of packages, there are eight options to choose from when it comes to Singapore eSIM, with the Singapore unlimited data eSIM for 5 days, costing 19 USD being the most popular one. Compared to the eSIMs offered by Airalo, Alosim, Nomad, and SimOptions (which are discussed in this guide), these eSIMs come with a higher price tag.

However, Holafly sets itself apart by offering unlimited data for durations of up to 90 days. There is a caveat though: starting in August 2023, Holafly's eSIM speeds are capped at 18 Mbps (even with 5G NR access), except for its Europe eSIMs.

This speed limitation was not in place before that month. I personally used the Europe eSIM extensively in July 2023, enjoying normal to fast speeds until I traveled to North America in August 2023 and noticed the throttled speeds across all countries I visited thereafter.

While 18 Mbps is decent, it is not exceptional—especially considering I have experienced download speeds of up to 160 Mbps in various European locations. However, if top speeds are not your priority, then this speed restriction may not be a concern for you.

Next, we have the Holafly Asia eSIM, which can be used in 32 countries, including Singapore. Similar to Holafly's Singapore eSIM, this one also comes with a speed restriction of 18 Mbps.

However, unlike the Holafly Europe eSIM (which is discussed in this review), the Holafly Asia eSIMs are priced higher compared to country-specific Holafly eSIMs.

The Holafly Asia eSIM allows usage for a duration of up to 30 days, with the cost now reaching a maximum of 79 USD (up from 64 USD as of August 2023). In comparison, the Europe eSIM is priced at 64 USD.

I have heard that Holafly is actively working to lower prices and provide more choices, although this process might take some time. Right now, there are six options to choose from, with the Asia unlimited data eSIM for 15 days, costing 47 USD being the most popular one. 

If you are visiting multiple countries during your trip, getting an Asia eSIM is both more economical and practical, as it will save you some money, and you will not have to switch providers or purchase another eSIM or traditional SIM card. If you want to see in which countries you can use Holafly Asia, I got you covered, as I have a Holafly Asia review on my blog.

Nomad eSIM for Singapore

Nomad typically offers the most budget-friendly eSIMs for Asian countries, with generous data allowances ranging up to 50 GB and occasionally even reaching 100 GB.

Furthermore, certain destinations feature unlimited data plans through Nomad.

I highly recommend Nomad eSIMs for a wide range of Asian destinations due to these advantages. For Singapore, there are 4 eSIM types to choose from:

  • Singapore: local use only;
  • APAC: Singapore and 14 or 19 other countries in Asia and Oceania, depending on the eSIM;
  • SEA-Oceania: Singapore and 7 other South Asian and Oceanian countries;
  • Global: Singapore and 109 or 138 other countries, depending on the eSIM.

The Nomad Singapore eSIM has ten options to choose from, with the Singapore 5 GB eSIM for 30 days priced at 10 USD being the most popular one. The provider also offers ‘unlimited’ plans, but there is a catch (not surprised anymore): you can only use 2 GB per day. But, unlike other providers, Nomad is pretty straightforward about this. There are 5 unlimited data plans, with the Singapore “unlimited” (2 GB) eSIM for 1 day priced at 7 USD being the most popular of them all. The eSIM uses a Singtel network, so make sure you switch on it. 

It is worth noting that Nomad Singapore eSIM operates under JoyTelecom, a subsidiary of Hong Kong Telecom (HKT) and CSL Mobile.

While this fact may not pique everyone's interest (except for us nerds 🤓), eSIMs powered by JoyTelecom are subject to throttling at either 42 Mbps or 82 Mbps, depending on the specific country. This is faster than Holafly eSIM, but it is still worth noting, just for the record. 

If you are visiting Singapore and its neighboring countries, Nomad APAC eSIM and Nomad SEA-Oceania eSIM might pique your interest. 

Let us dive into the Nomad APAC eSIMs, which come in two variants: the 15 Countries Plan and the 20 Countries Plan.

The 15 Countries Plan is powered by JoyTelecom and comes with speed restrictions, while the 20 Countries Plan is supported by eSIM Go.

Despite covering fewer countries (15), eSIM Go eSIMs are generally pricier compared to JoyTelecom eSIMs (20 countries).

For a more detailed comparison between these two providers, check out my ongoing Nomad APAC eSIM review. But for now, remember that both the 15 Countries Plan and the 20 Countries Plan eSIMs are compatible in Singapore. There are eleven options to choose from, with the APAC (20 Countries Plan) 20 GB eSIM for 45 days, costing 29 USD being the most popular of them all. 

Unlike the Nomad APAC eSIM, the Nomad SEA-Oceania eSIM does not offer distinct “country plans.” Instead, all eSIM options encompass the same eight countries: Australia, Indonesia, Malaysia, New Zealand, the Philippines, Singapore, Thailand, and Vietnam. There are six options to choose from, with the most popular being SEA-Oceania 10 GB eSIM for 30 days, costing 19 USD.

Let us talk about Nomad's Global eSIM, which is usable in Singapore.

Personally, I have never been a fan of this eSIM due to its high cost. While I understand that an eSIM covering over 100 countries would naturally be expensive, there are more affordable alternatives available, particularly Airalo's Global eSIMs.

This is why I do not use this eSIM—it is simply too pricey for my liking.

However, I include it in this guide because some of my readers at Phone Travel Wiz appreciate and actively use this eSIM.

In the past, when Airalo's global offering covered 84 countries and Nomad's covered 110 countries, there was a noticeable price difference, with Airalo's being significantly cheaper and even offering call and text features.

Since June (Nomad) and July (Airalo) partnered with eSIM Go for their global offerings, both now cover 130+ countries with their eSIMs. However, Airalo's remains notably cheaper than Nomad's and includes the call and text feature.

Whether Nomad will introduce similar features soon is uncertain. However, I suspect that the popularity of Nomad's global eSIM might decrease due to Airalo's improved offering.

There are six options to choose from, with the Global (109 Countries Plan) 5 GB eSIM for 30 days costing 45 USD and the Global (139 Countries Plan) 5 GB eSIM for 30 days costing 57 USD being the most popular with Phone Travel Wiz readers.

SimOptions eSIMs for Singapore

SimOptions has AIS eSIM2FLY Asia eSIM that can be used in Singapore and its neighboring countries. 

The eSIMs provided by SimOptions are generally pricier compared to Nomad's offerings. I would not want you to spend more money when there are cheaper alternatives available, especially when they are using the same partner network.

However, the AIS eSIM2FLY eSIM stands out as a different option. It is offered by AIS Thailand, which was formerly Thailand's largest mobile operator until TrueMove H and Dtac Thailand merged into True Corp. The eSIM can be used in 32 countries, predominantly in Asia. 

You are getting all the benefits this eSIM offers for only 19.90 USD, but there is a catch: you only get 6 GB for eight days. So, if you are staying in Asia for a prolonged period of time, this eSIM is not the best choice for you. 

Wrap Up: The Best Singapore eSIMs

What a journey it has been! The range of tourist SIM options available for Singapore, or those covering it, is extensive.

And this list is by no means exhaustive! There are numerous other eSIM providers offering services for Singapore as well.

However, the five I have included in this guide have received positive reviews. Additionally, I have extensively tested them across multiple countries and continents, consistently having positive experiences with each one.
