What is aloSIM and how does it work?
aloSIM is a Canadian eSIM travel provider: it sells prepaid mobile data for more than 200 destinations through an app, without a physical card or local contract. You buy the package, install the digital profile on your phone, and connect to a local network in the country you visit as soon as you arrive.
The company is owned by AffinityClick, based in Ottawa (Ontario, Canada), and presents its product as a way to avoid roaming charges and searching for Wi-Fi while traveling (source: alosim.com/about/, consulted on August 4, 2026). Its app is available for iOS and Android, and you can also buy and activate the eSIM profile from your browser.
If you have never used an eSIM and want to understand the technology before comparing providers, in our guide on what an eSIM is we explain how the digital chip works and how it differs from a physical card.
Does aloSIM work in Mexico?
Yes. For its Mexico plans, aloSIM connects to the Claro network through AMX Group, with typical LTE (4G) speed and 5G in some locations, according to its own product page for Mexico (source: alosim.com/mexico-esim/, consulted on August 4, 2026). Since it relies on a single local network, the quality of the signal during your trip will depend on Claro's coverage in the specific area where you travel: good in cities and tourist centers, more irregular in rural or mountainous areas, as is usually the case with any Mexican operator.
Before buying, it's worth confirming that your phone is eSIM compatible. If you have doubts, check our list of eSIM-compatible phones before paying for any plan, whether from aloSIM or another provider.
How to activate aloSIM eSIM?
aloSIM's own activation guide describes the process in five steps: install the eSIM profile (requires internet), prepare your phone so that the main line does not roam, activate the optional free international number, use mobile data upon arrival at the destination, and, if necessary, buy more data from the app (source: alosim.com/how-to-activate-esim/, consulted on August 4, 2026).
One detail that almost no one reads until they are already at the airport without Wi-Fi: the eSIM profile must be installed with an internet connection before traveling (with Wi-Fi at home or data from your current plan), although it is not activated or starts deducting days until you arrive at your destination and turn it on manually. If you wait until you are already at your destination, without Wi-Fi or data, to download the profile for the first time, you may be unable to install it.

aloSIM plans in Mexico: how they are structured
We are not going to publish a table of aloSIM prices here: the prices of any eSIM provider change without notice, and a frozen list in an article would lead you to make decisions with outdated information. What is useful, and does not expire so quickly, is to understand how the catalog is structured, so you know what to compare when you open their website. This is the structure of the gigabyte packages for Mexico published on their official page (source: alosim.com/mexico-esim/, consulted on August 4, 2026):
| Plan duration | Data volume |
|---|---|
| 7 days | 1 GB |
| 15 days | 2 GB |
| 30 days | 3 GB |
| 30 days | 5 GB |
| 30 days | 10 GB |
| 30 days | 20 GB |
Two things to look at in this table and any similar one. First: the duration is counted from when you activate the plan, not from when you buy it, so a 7-day package will not cover a ten-day trip even if you have gigabytes left over. Second: the price per gigabyte is almost never linear, and smaller packages are usually much more expensive per gigabyte than larger ones, so comparing only the entry price can lead you to make the wrong choice.
In addition to these gigabyte plans, aloSIM offers "unlimited per day" packages, with a fixed daily charge. This modality comes with a fair use policy: 3 GB at high speed per day, and once that limit is exceeded, the speed is reduced to 1 Mbps until the next day (source: alosim.com/mexico-esim/, consulted on August 4, 2026). It is advisable to read the fine print of each plan before purchasing, because "unlimited" almost never means high speed without limits: the norm in this category is a daily threshold and a speed reduction afterward.
aloSIM coverage worldwide
aloSIM announces coverage in more than 200 countries and destinations, with country-specific packages, regional packages (e.g., Europe or North America), and global packages for those visiting several continents on the same trip (source: alosim.com/llm-info/, consulted on August 4, 2026). The entry price varies greatly from one destination to another, because it depends on what each local operator charges the provider for data traffic; that is why the same volume of gigabytes can cost very differently in two neighboring countries.
If your itinerary crosses borders, a regional package may be cheaper than buying an eSIM country by country, but only if you actually plan to use data in several of the included destinations. If your trip is to a single country, a local plan is usually more efficient.

aloSIM customer support and refunds
According to its "About Us" page, aloSIM offers two support channels: email (support@alosim.com) and live chat available 24 hours a day within the app and on the website. Telephone or WhatsApp support is not mentioned (source: alosim.com/about/, consulted on August 4, 2026).
Its refund policy offers a 30-day guarantee for cases where the customer's device turns out to be incompatible with eSIM or the user has problems connecting to the local network; the aloSIM team requests proof of purchase and an explanation of the problem to process the refund (source: alosim.com/refund-policy/, consulted on August 4, 2026).
Before buying any travel eSIM, check which channel provides support and during what hours. If the only channel is an in-app chat and your problem is precisely that you cannot connect, you will need Wi-Fi to ask for help. A channel that works outside the app —email or messaging— gives you an alternative.
What are the reviews about aloSIM?
We are not going to invent a number of stars or a number of reviews for you: these data change all the time and the most honest thing is that you check them yourself, at the time you are going to buy, directly on Trustpilot, the App Store or Google Play.
What we can give you is a method to read these reviews without being confused, because in this category the average rating says very little. A travel eSIM relies on the local operator's network in each country, so the same brand can accumulate excellent reviews from people who used it in Europe and bad reviews from people who used it in a destination where its partner operator has poor coverage. The overall rating mixes both things.
Therefore, when you open Trustpilot, the App Store, or Google Play, filter by what really affects you. Look for reviews of the specific destination you are going to, not of the provider in general. Look at the date: a complaint from two years ago may refer to an agreement with an operator that has already changed. See if the reported problem is with the network (signal, speed) or with the product (the profile does not install, the plan does not activate, support does not respond), because the first depends on the country and the second on the provider. And read how the company responds to complaints: the response pattern usually anticipates quite well what will happen to you if something goes wrong.
aloSIM vs PuraSIM: objective comparison
Here are the verifiable data for each provider, side by side, without adjectives:
| Feature | aloSIM | PuraSIM |
|---|---|---|
| Destinations covered | More than 200 (alosim.com/llm-info/, consulted Aug 4, 2026) | More than 200 |
| Support channels | Email and 24/7 live chat; does not publish phone or WhatsApp among its channels (alosim.com/about/, consulted Aug 4, 2026) | Email and WhatsApp, 24/7, in all languages |
| Advertised activation time | Check current data on their website | Approximately 1 minute |
| Activation period from purchase | Their guide indicates that eSIMs do not expire and that you can top up data when you need it (alosim.com/how-to-activate-esim/, consulted Aug 4, 2026) | 180 days |
| Refund guarantee | 30 days, subject to device compatibility or network failure (alosim.com/refund-policy/, consulted Aug 4, 2026) | Check current conditions on the product sheet |
Neither is "better" automatically: it depends on whether you care more about having a WhatsApp channel to resolve urgent questions, how much margin you need before activating the plan, or simply what destination and what gigabyte price suits you for that particular trip.

Which company has eSIM in Mexico?
In Mexico, there are two distinct categories of eSIM, and it is important not to confuse them. On one hand, there are local operators (Telcel, AT&T Mexico, Movistar Mexico) that offer eSIM as a permanent line: they require an activation process, identification, and, in many cases, a local address. On the other hand, there are travel eSIM providers —like aloSIM or PuraSIM— that sell prepaid data packages, without a contract or local identification, designed for tourists or those who only need internet during a short stay.
If your situation is the latter (you are visiting Mexico, or traveling out of Mexico), a travel eSIM is usually the simplest option: you don't need a tax address or to go to a physical store. To compare this alternative against the traditional physical SIM card, check eSIM vs. physical SIM: what suits you best.
Which physical network you actually connect to
A travel eSIM is not a network of its own: it roams on local operators. Which ones you get decides your real coverage, and almost no provider publishes it. These are the networks a PuraSIM eSIM uses, taken from our own carrier agreements and checked on 2 September 2026.
| Destination | Networks you roam on | Technology | Top-up |
|---|---|---|---|
| Japan | NTT docomo · Rakuten Mobile · KDDI/au · SoftBank | 5G | Yes |
| United States | T-Mobile · AT&T | 5G | Yes |
| Spain | Orange · Movistar | 5G | Yes |
| United Kingdom | O2 · EE · 3 | 4G/5G | Yes |
| Thailand | TrueMove H · DTAC | 5G | Yes |
| Mexico | Telcel · AT&T | 5G | Yes |
| Greece | Wind · Vodafone | 5G | Yes |
| Turkey | Vodafone | 5G | Yes |
Two questions are worth asking about any travel eSIM, aloSIM included. First, how many networks you get in your destination: where a plan runs on a single operator you have no fallback if that operator is weak where you are staying. Second, whether the plan can be topped up — if it cannot, running out of data means buying and installing a second eSIM mid-trip.
We publish this table because it is the part of the comparison you can check yourself: land, open your phone settings and read the operator name on screen. PuraSIM covers more than 200 destinations, and the network partners are listed on each destination page.

We do not publish a rating or a number of reviews, because they change constantly and it is honest for you to check them on Trustpilot, the App Store or Google Play before buying.

Conclusion
aloSIM is a real and verifiable option for getting mobile data for travel in Mexico and over 200 destinations, with a simple app, gigabyte or daily plans, and 24/7 email and live chat support.
