When you travel, the last thing you want is to waste time looking for a local SIM or lose data unexpectedly. The Roamless eSIM was created precisely to avoid those situations. It’s a virtual card that installs once and works across 200+ destinations without changing anything when crossing borders.
In this Roamless eSIM review, we’ll explore in detail what it offers and whether it’s truly the most practical solution for frequent travellers.

How Does the Roamless eSIM Work?
Instead of installing a different eSIM in each country, Roamless lets you download one global profile directly from the official app. Available for both iOS and Android, this same eSIM follows you on every trip and connects automatically to the local network wherever you are.
The experience feels very similar to using a physical SIM card, as you just activate mobile data when landing. However, Roamless gives you two payment options:
- RoamlessFlex: you can top up balance in the app and use it gradually depending on your data usage. The credit never expires, which is convenient for travellers who move irregularly or combine destinations within a short period.
- RoamlessFix: it works like traditional plans, offering a set number of gigabytes for 30 days. You can choose, for instance, a 5GB package for the United States or Europe and forget about recharging until it’s finished or the month ends. This plan suits longer trips or those expecting high data use during their stay.
In both cases, the Roamless eSIM allows data sharing via hotspot. Also, where local networks support it, you can connect through 5G for faster browsing, map use, photo uploads, social media updates, or even remote work if needed.
Another interesting detail is that the app lets you make international calls using your credit. However, traditional SMS or local numbers aren’t available yet.
Overall, it’s a simple and direct process. You just install the eSIM once, choose whether to pay per use or monthly, and it’ll connect automatically every time you arrive in a new country.
What Features Does the Roamless eSIM Have?
The first thing that stands out about the Roamless eSIM is its simplicity. You don’t need to install different profiles per country or worry about your plan expiring mid-trip. You only need to download one global eSIM, and that’s it. From there, choose to pay per use with Flex or get a monthly plan with Fix. No need to deal with complex technical setups.
To make it even clearer, here’s a summary of its main features:
| Feature | Details |
| Type | Single global eSIM (one profile for 200+ countries) |
| Payment Options | Flex (prepaid balance without expiry) or Fix (monthly data plans) |
| Coverage: | Over 200 countries and regions |
| Connection | 4G and 5G (depending on local network) |
| Hotspot | Yes, allows data sharing with other devices |
| Calls | Within the app, from $0.01 (€0.01)/min |
| SMS | Not available yet |
| App | Available on iOS and Android |
Coverage by regions and countries
One of the first things travellers check before buying an eSIM is its coverage. The Roamless eSIM works in over 200 countries, so you’ll probably have no issues in most common destinations.
You can view the full destination list on their website. However, here’s a quick regional summary to help you get a clear idea:
| Region | Included Countries (examples) |
| Europe | All EU countries, the United Kingdom, Switzerland, Norway, Turkey, and more |
| North America | United States, Canada, Mexico |
| Latin America | Brazil, Argentina, Chile, Peru, Colombia, and others |
| Asia | Japan, South Korea, China, Thailand, India, Vietnam, Indonesia, and more |
| Oceania | Australia, New Zealand, Fiji |
| Africa | South Africa, Egypt, Morocco, Kenya, and several others |
As you can see, it doesn’t matter if you’re doing an Interrail across Europe, a route through Asia, or a combined trip around Latin America. The Roamless eSIM will keep you connected without needing to search for local solutions in every country.
Although Roamless promises coverage in over 200 countries, it’s natural for many travellers to wonder how it performs in specific destinations.

User Reviews on Trustpilot
One of the most reliable ways to see if a service delivers what it promises is by checking real user reviews. In the case of Roamless eSIM, Trustpilot ratings give it an average score of 3.9 out of 5, showing medium satisfaction. It’s not a total failure, but it doesn’t inspire complete confidence either.
Many travellers praise its ease of use. Installing this eSIM is very straightforward, and once activated, it runs smoothly. They also value the convenience of having one single profile valid in over 200 countries, which is great for long trips or multi-stop itineraries.
However, one common complaint repeats: the connection isn’t always stable in every destination. Sometimes, it takes longer to connect to the best local network. Also, prices per gigabyte can be higher than local SIMs, especially in countries with cheaper mobile rates.
This is where comparing other options becomes useful. For instance, you can read our review of the Sailu Ultra Plan to see what users say about that provider.
In short, reviews show that the Roamless eSIM works well if you want simplicity and convenience. However, it might not satisfy travellers who seek the lowest price or unlimited data.
Why Is the Roamless eSIM Rating So Low on Trustpilot?
The main reason behind that 3.9 score is the uneven experience depending on the destination. In some countries, the connection is fast and reliable, while in others users report drops, slow speeds, or trouble activating plans. They also mention the lack of unlimited data, which many travellers now consider essential.
In reality, that rating doesn’t mean the Roamless eSIM is bad. It simply shows that it can be a great option for some trips but may disappoint in others.
What’s the Best Alternative to the Roamless eSIM?
After seeing what Roamless offers, it’s fair to ask whether there are better options for your travel style. That’s where the Holafly eSIM comes in, the most popular alternative when it comes to travel eSIMs.
The main difference compared with Roamless is that Holafly offers unlimited data plans in many countries and regions. You won’t need to worry about how many gigabytes you use when checking maps, sharing photos, or working remotely. If you need constant internet access, this feature is essential.
Another advantage is its flexibility in choosing plans. You can select a specific country plan or a regional one covering several destinations on the same trip. That way, if your route includes multiple countries within one area, you won’t need to buy new eSIMs at every border. To see all available options, you can check Holafly plans and compare which one suits your itinerary best.
Holafly also provides 24/7 English-language support via chat, offering full peace of mind. From a practical point of view, installation is as easy as scanning a QR code and activating your eSIM before travelling.
So, if you’re after maximum comfort and unlimited data, Holafly is the best alternative. The Roamless eSIM can be interesting for those who prefer paying only for what they use. But if you consume lots of data or don’t want to monitor usage, Holafly’s unlimited plans are undoubtedly the right choice.

Frequently Asked Questions about Roamless SIM
The Roamless eSIM does allow calls, but not in the traditional way. Everything works through its app, where you can call international numbers using your credit from €0.01 ($0.01)/minute depending on the country. However, traditional SMS aren’t available. For most travellers, communication works perfectly via WhatsApp, Telegram, or iMessage.
The main difference lies in the data model. With the Roamless eSIM, you must choose between paying per gigabyte (Flex) or a 30-day data plan (Fix). Meanwhile, providers like Holafly let you access unlimited data so you won’t worry about losing connection mid-trip.
Not all. To use it, you’ll need a smartphone compatible with eSIM. Most recent models from major manufacturers are, but it’s highly recommended to check the official compatibility list before purchasing. If your phone doesn’t support eSIM, this service won’t work for you.
