What is ICC eSIM?

ICC is a telecom provider based in Singapore that specialises in prepaid eSIMs for travellers. The service is fully digital, meaning you can buy, activate, and manage your plan online without needing a physical SIM card.

What sets ICC apart is its flexibility: you can choose between single-destination packages, regional bundles, or multi-country passes depending on your trip. 

This makes it especially useful for short-term stays, business trips, or travellers moving between multiple destinations in one journey.

ICC eSIM review: The details

To understand how ICC compares with other travel eSIM providers, it helps to look closely at what they offer. 

From coverage and pricing to customer support and refund policies, each factor can make a difference in whether ICC is the right choice for your trip.

ICC eSIM Coverage

ICC eSIM offers single-country, regional, and multi-destination bundles, covering over 100 locations with a strong focus on Asia.

If your trip takes you to multiple countries, ICC also has regional plans for Southeast Asia, Europe, or North America. For example, a single plan can keep you connected across Thailand, Indonesia, and Vietnam.

There are also multi-destination passes, such as China–Hong Kong–Macau or Malaysia–Thailand, which means you don’t need to buy a new SIM every time you cross a border.

Data plans and pricing

ICC eSIM plans vary by destination and duration, with both daily data caps and total GB options. 

Here are some of the most popular ICC eSIM Single-destination plans and pricing:

If you’re travelling across several countries, ICC also offers regional eSIM bundles. Giving you one plan that works in multiple destinations without switching cards. 

Here are some of the ICC eSIM Regional plans and pricing:

ICC also offers multi-destination plans for travellers moving between neighbouring countries. Here you can take a quick look at some of the most popular multi-destination packages ICC offers:

Notes:

• All ICC eSIM plans follow a high-speed data + unlimited data model. This means you get a fixed amount of 4G/5G data per day (or total, depending on the plan). Once you’ve used that allowance, your connection continues at a reduced speed instead of cutting off. 
• Plans include either daily high-speed caps or total GB allowances, with reduced speed afterwards.

Before purchasing an ICC eSIM, check if your device is eSIM-compatible and make sure the device is unlocked from other carriers.

ICC Customer Support

ICC offers several support channels to help travelers with eSIM activation or connectivity issues. You can reach their team through:

• Email: direct assistance for account or payment problems
• Live chat: available on the ICC website and app for quick questions
• In-app help: step-by-step guides and troubleshooting tips

Response times can vary, but most queries are handled within a few hours. Since ICC doesn’t offer 24/7 support, highlight that live chat is the only near-instant option when travelling.

ICC eSIM Refund Policy

If your eSIM doesn’t work because of a technical fault on ICC’s side, you can request a full refund, but only if you contact customer support during your travel period. Refunds must be requested during your travel.

On the other hand, refunds are not available if the issue comes from misconfiguration, not following eSIM setup instructions, or simply changing your mind. 

In rare cases, ICC may agree to a refund or exchange on a goodwill basis, but a $5 service fee per item applies.

In short, ICC refunds only apply for verified technical faults, and all claims must be made promptly while you’re still traveling.

ICC eSIM top-up

Many ICC plans can be topped up and reused. Instead of buying a brand-new eSIM each time, you can extend your data or days directly from the same profile. This is especially handy if your trip gets extended or you run out of high-speed data sooner than expected.

Top-up options depend on the plan you choose (for example, single-country vs. regional), and you’ll see the available add-ons at checkout or in your ICC account. 

Since plans often include a daily data allowance plus unlimited usage at reduced speed, topping up ensures you keep enjoying full-speed data.

Can ICC eSIM use WhatsApp in China?

Yes, ICC eSIM works with WhatsApp and other apps that are normally blocked when you use a local China SIM card. Unlike traditional carriers that follow local restrictions, ICC eSIM routes traffic through international networks, so you can access WhatsApp, Instagram, Facebook, Gmail, YouTube, and more, all without needing a VPN.

If you’re traveling to China and rely on WhatsApp to stay in touch, ICC eSIM can be a convenient solution since it provides instant delivery and activation before you land.

Is the ICC eSIM worth it?

ICC is an affordable travel eSIM and works reliably, even in restrictive markets like China. However, the sheer number of plans, durations, and data types can be confusing, especially if you just want something simple and quick to set up.

So yes, ICC can be worth it, but it’s not the only option. If you’d rather keep things simple with unlimited data and easy setup, Holafly’s eSIM is another alternative worth considering.

Stay connected anywhere with Holafly’s unlimited data

Most Holafly eSIMs include unlimited data with no speed caps and work in 200+ destinations worldwide. 

You can choose between a daily eSIM plan ranging from USD $1.55 to USD $7.90 per day, or Holafly Plans, a subscription starting at USD $49.90 per month. Both options include:

• Unlimited data with no speed caps or throttling
• Near-worldwide coverage, ideal for frequent travellers
• 24/7 multilingual support
• Tethering and hotspot sharing
• Instant setup with no in-app activation

In the end, it depends on what you value most: ICC for variety and budget pricing, or Holafly for unlimited data and peace of mind wherever you go.
