How to get a WOM eSIM?
The WOM eSIM is requested directly from WOM, as a local carrier in Colombia or Chile, and usually requires the standard sign-up process for any local line. If you’re only passing through or visiting more than one country, an international eSIM for travelers activates before you arrive, without any of that paperwork.
It’s important to separate two searches that often get mixed up. One is for someone living in Colombia or Chile, or settling there for an extended period, who wants a local line with their own number, plans in local currency, and in-person support if needed. The other is for a traveler arriving for a few days or weeks, with a phone already bought in their home country, who only needs mobile data for maps, social media, and ride-hailing apps during the trip. WOM, like any local phone carrier, is mainly designed for the first case.
If you fall into the second group, you’re better off comparing options before deciding. An eSIM international for travelers doesn’t replace a local line in every way, but it covers exactly what someone passing through needs: mobile data on your phone, without changing your number, visiting a store, or relying on a local sign-up process finishing on time.
Where can I buy a WOM eSIM in Colombia?
For a local WOM line, the most direct route is the carrier’s own channel: its website, its app, or its physical service points in the country. That’s where you complete the sign-up, choose your plan, and verify your identity, just like with any local carrier in the region.
The point that often raises questions is what happens if you need connectivity before arriving in Colombia, or if your trip also includes other countries in the region. A local line gets activated once you’re physically in the country and have completed the relevant paperwork; it’s not designed to be bought in advance from abroad or used outside its national coverage. That’s a reasonable limitation for a local carrier, but it may not fit a traveler’s logistics.
That’s where the alternative of buying connectivity before you leave home comes in. With an international eSIM, you can choose your plan, pay, and receive the activation QR code from your home country, and activate it right when you land. If your route crosses several Latin American countries, this avoids repeating the sign-up process at every border.
How to buy an eSIM online? The real steps
The process, regardless of provider, follows a similar pattern: choose the destination and data amount, pay online, receive the QR code or activation profile by email, install it on your phone, and activate the data line when you need it, usually upon arrival at your destination.
In practice, it’s a good idea to buy the eSIM before your trip, not at the arrival airport, because public Wi-Fi is unreliable just when you least need it: when leaving the terminal, ordering a ride, or finding your accommodation. Buying it in advance also gives you time to check that your phone is compatible and to install the profile at your own pace, with stable Wi-Fi, rather than doing it with limited data or weak coverage.
One detail that’s rarely mentioned: if your travel plan includes getting a WOM line because you’ll be staying for a while, you don’t have to choose one or the other. You can use the international eSIM as a bridge connection for the first few days while the local sign-up process is underway, and activate the WOM line when it’s ready for permanent use. That way you don’t rely on the paperwork being done the same day you land.
To install the profile on your phone, the full step-by-step guide is at how to install an eSIM, and it’s worth reading before you buy, not after.
How to request a virtual eSIM: Requirements and compatible phones
To request a virtual eSIM, whether from a local carrier like WOM or an international provider for travelers, the technical requirement is the same: your phone must be eSIM-compatible and unlocked from the factory or carrier. Most mid-range and high-end models released from 2020 onward are, but not all, and it's not always clear without checking.
Before buying any eSIM, a quick check is worth it: go to your phone's settings and look for the option to add an eSIM plan, or check the list of eSIM-compatible phones. If your model isn't listed or your phone is locked to a specific carrier, no eSIM will work, no matter who you buy it from.
The difference between requesting a WOM eSIM and an international eSIM lies in what comes after compatibility. WOM, as a local carrier, typically requires identity verification tied to the country where it operates, as is standard for a line with a real phone number. An international eSIM for travelers, on the other hand, is data-only: it doesn't include its own voice number or SMS, so the sign-up process is simpler, but it also doesn't serve the same purpose. It's worth being clear on this before deciding based on what you need to use during your trip.
Coverage: Local line vs. international eSIM for travel
Coverage is where the difference between a local carrier and a traveler-focused eSIM is most noticeable. A WOM line covers the territory where WOM operates as a local network; outside that country, it depends on roaming agreements the carrier has in place, if any, and it's best to confirm directly with WOM before crossing a border. An international eSIM for travelers, on the other hand, is designed from the start for moving around: multi-destination plans cover several countries with the same profile, with no reconfiguration needed when changing countries.
| Criterion | Local line (e.g., WOM) | International eSIM for travelers |
|---|---|---|
| Geographic coverage | The country where the carrier operates; outside that, depends on roaming agreements | Over 200 destinations, with single-country or multi-destination options |
| Phone number | Yes, a local number with voice and SMS | No voice number; it's a data profile |
| Sign-up process | Identity verification as a local carrier, in the country | Online purchase, no in-person process |
| Designed for | Residents or long stays with daily life in the country | Short trips, multi-destination travel, or while sorting out other arrangements |
If your route will include more than one country in the region, comparing the actual coverage of each option before deciding avoids surprises. The guide on eSIM vs. physical SIM goes into more detail on the technical differences between the two formats.
Activation: How long each option takes and what you need on hand
With an international eSIM, activation usually takes about a minute once you scan the QR code with Wi-Fi available, because the plan was already linked to the purchase you made before traveling. There's no need to go anywhere or present documentation on the spot.
With a local line like WOM, activation time depends on the channel and the identity verification process required by any local carrier, which can be resolved the same day in a store or take longer depending on the channel you use. This is information only the carrier can confirm accurately for your case, so it's best to ask them directly before counting on that line for the first day of your trip.
If your trip crosses more than one country, or if you need connectivity from the moment you land, activation time matters as much as coverage. An eSIM that's already purchased and ready before you leave home removes that variable; a line that depends on a local process does not.
Support: What happens if an issue arises outside Colombia or Chile
Support from a local carrier is logically designed to handle inquiries within its country of operation. If you have a problem with your WOM line while outside Colombia or Chile, the contact method and response times depend on the channels WOM has available for users abroad—something worth checking with the carrier before leaving the country, especially if you'll be relying on that line during your trip.
With an international eSIM for travelers, support is designed for that situation from the start: it's available 24/7 in English via email and WhatsApp, no matter which country you're in when you write. There is no phone support as such in either of the usual support models for travel eSIMs, so it's worth confirming the actual channels you can use before you need them, not when you already have the problem.
The most common issues when using an eSIM, and how to solve them without waiting for a reply, are covered in common eSIM problems.
Fair Usage Policy on "Unlimited" Plans
When a data plan, whether from a local carrier or a travel eSIM, is advertised as "unlimited," there is almost always a fair usage policy behind it: a consumption threshold after which the speed is reduced, even though the connection isn't cut off. This is a standard industry practice, not hidden fine print, but it's worth reading before you buy if your travel plans include working online, live streaming video, or relying on mobile data as your main connection.
The practical advice is the same for any provider: before choosing an "unlimited" plan, look for where the fair usage policy is published and confirm at what point the speed changes. If that information isn't visible anywhere, it's a red flag, not a guarantee that no such policy exists.
Validity and Expiration: When Each eSIM Expires
With an international eSIM for travelers, there are two different timeframes you shouldn't confuse: the time you have to activate it after purchase, and the plan's duration once activated. With PuraSIM, you have 180 days from purchase to activate the eSIM, giving you plenty of leeway to buy it in advance without it expiring before your trip. The plan's duration itself (the data days you purchased) only starts counting when you activate the line, not when you buy it.
With a local WOM line, since it's a line with its own number, the validity works differently: as long as you keep the plan active or make top-ups periodically, the line keeps working; if you stop topping up for an extended period, the carrier may deactivate it according to its own policies, which you should check directly with WOM.
When Does a WOM eSIM Make Sense, and When Doesn't It?
Being honest about this is what makes a comparison useful. A local WOM line makes clear sense if you're going to live in Colombia or Chile for a long time, if you need a local phone number for paperwork, banking, or apps that require SMS verification, or if your data and call usage will be that of someone settled in the country, not a passerby. In that scenario, an international data-only eSIM can't replace it.
An international eSIM for travelers makes sense when the trip is short or medium-length, when the itinerary crosses more than one country, when you want connectivity active from landing without relying on a local process, or when you simply don't need a new phone number because you already have WhatsApp and email working from your home line.
| Traveler Type | Most Reasonable Option | Why |
|---|---|---|
| Short-stay tourist (days or a few weeks) | International eSIM | Activation in ~1 minute, no in-person process or new number |
| Multi-destination trip in the region | Multi-destination international eSIM | Single profile covers several countries without reconfiguring anything |
| Person moving to Colombia or Chile for months or years | Local line (WOM or another carrier) | Needs own number, local plans, and continuous presence in the country |
| Moving but arriving before the local line is ready | International eSIM as a bridge + WOM process in parallel | Immediate connectivity while sorting out local identity verification |
If your case is one of the first two, it makes sense to check the available plans by destination directly, as detailed in the conclusion. If it's the third, a WOM line is likely the right decision, and this comparison shouldn't convince you otherwise.
Frequently Asked Questions
Can I use a WOM eSIM outside of Colombia or Chile?
It depends on the international roaming agreements WOM has in place at any given time, which only the carrier can confirm. This isn't a limitation unique to WOM: most local carriers in the region work the same way, with guaranteed coverage within the country and roaming as an exception, not the rule.
Do I need to verify my identity to activate an international eSIM for travelers?
Not in the same way as with a local line. Since it's a data profile without its own voice number, the purchase and activation process for an international eSIM is simpler than signing up for a local line with identity verification in the country.
What phone do I need to use any eSIM, whether WOM or international?
A phone that is eSIM-compatible and unlocked from the factory or carrier. Without that, no eSIM works, regardless of the provider. It's worth checking before you buy, as explained above.
What happens if my international eSIM runs out of data mid-trip?
You can purchase an additional or top-up plan from the same account, without needing to install a new profile. If the issue is something else, like the connection not appearing, 24/7 support by email and WhatsApp is available in all languages to resolve it while you continue your trip.
Can I have a WOM eSIM and an international eSIM active at the same time?
Yes, as long as your phone supports dual eSIM or combines a physical SIM with an eSIM, which is common on recent models. This is exactly what allows you to use an international eSIM as a bridge connection while completing the local line sign-up process.
Can the international eSIM receive bank verification codes via SMS?
No. Since it doesn't include a voice number or its own SMS, an international data eSIM cannot replace a local line with a phone number for that type of verification. For that, you need a line with a number, like the one offered by a local carrier.
How far in advance of the trip should I buy the eSIM?
With enough time to check your phone's compatibility and avoid relying on the arrival airport's Wi-Fi to install the profile. Since you have 180 days to activate it from purchase, there's no risk of buying it too far in advance.
Conclusion and Recommendation
The question "WOM eSIM yes or no" doesn't have a single right answer, and any comparison that tells you otherwise is oversimplifying. If you're going to live in Colombia or Chile for an extended period and need a local number, WOM (or any equivalent local carrier) is the right tool for that job. If you're traveling, whether to one country or several, and what you need is data connectivity that works from the moment you land without in-person processes, an international eSIM for travelers solves exactly that, with 24/7 support in all languages by email and WhatsApp and 180 days to activate it from purchase.
For anyone torn between the two because their plan combines both situations (arriving and staying), the honest answer is that you don't have to choose: the international eSIM covers the first few days while the local line process is sorted out. If your case is a trip, check the available plans by destination in the international eSIM collection, and if you want the full picture before deciding, the ultimate eSIM guide for travel covers the rest of the criteria that don't fit in this comparison. And if after reading all this you're still sure you need a local line, that's the right decision for your case, not a second choice.
