How to activate Movistar Argentina eSIM
It's activated in three steps: you scan the QR code provided by Movistar (or enter it manually), the phone downloads the line profile, and you activate mobile data on that eSIM. If you have already completed the process with the operator and have the QR code handy, the technical process on the phone takes a couple of minutes.
Before touching anything in the settings, organize these three points in the order they usually fail, from most probable to least probable:
- Confirm that Movistar has already activated the line on their end. Scanning the QR before the operator completes the activation is useless: the profile will be installed, but the line will still have no data. Movistar will notify you by SMS or email when the line is ready.
- Scan the QR code with your phone's camera from Settings > Mobile Data (or Cellular) > Add eSIM, not from the photos app or WhatsApp: most systems require the scan to be done within the settings menu itself.
- If you cannot scan (for example, because the QR arrived as text or a link), look for the "Enter details manually" option and enter the SM-DP+ address and the activation code provided by Movistar.
- Activate the data line on that eSIM and, if you have another physical line or eSIM on the same phone, decide which one uses mobile data by default.
- Restart your phone if no signal appears after installing the profile. This is the step most people skip and the one that resolves most cases.
If you followed these steps and it still doesn't work, the problem is probably on the operator's side (line not activated, expired or already used QR) and not on the phone. Below, we review what to do with a non-working QR and how to resolve a lack of signal.
Where to activate Movistar eSIM
The QR code and activation data for a Movistar Argentina eSIM are managed through the operator's own channels: the Mi Movistar app, a physical branch, or Movistar's WhatsApp customer service. The profile installation, on the other hand, is always done in the phone's settings, without going through any app.
| Channel | Purpose | What you need to bring |
|---|---|---|
| Mi Movistar App | Request the line, check activation status, and, depending on the process, download or resend the QR | Active Movistar account and line details |
| Physical Branch | New line activation with identification, especially if in-person verification is required | Valid identification document in Argentina |
| WhatsApp / Customer Service | QR resend, questions about activation status, or process incidents | Line or transaction number |
| Phone Settings | Install the eSIM profile once you have the QR or manual code | The QR or SM-DP+ data, and internet connection (Wi-Fi or data) |
The most common confusion is thinking that the phone can "activate" the line on its own. This is not the case: the phone only installs the profile generated by Movistar. If the line is not yet enabled on the operator's side, the phone will show the eSIM installed but with no service.
How to get the QR code for Movistar eSIM
Movistar provides the QR code upon completion of the eSIM line activation, usually by email, within the Mi Movistar app, or at the branch where you completed the process. It's an image with a checkered pattern, unique each time: it's not generic or reusable between lines.
A detail that almost no one takes into account: an eSIM QR code is for single use. Once it's scanned and the profile is installed on a phone, that same QR can no longer be used to install it on a second device, even if the image remains perfectly legible. This means that if you change phones later, saving a photo of the code is not enough: you have to ask Movistar to re-issue a new QR associated with that line.
If the operator sent you the code as a link or text instead of an image, almost all phones allow you to manually enter that same data, without scanning anything, from the manual installation option in Settings > Mobile Data > Add eSIM.
How to enable the Movistar eSIM once installed
Installing the profile and enabling it to work are two different steps, and many users get stuck here. After scanning the QR, the phone saves the eSIM as another profile, but it doesn't necessarily leave it active for making and receiving calls or using data.
- Go to Settings > Mobile Data (or Cellular) and confirm that the Movistar line appears in the list of available lines.
- Activate it by tapping it, and if the phone asks which one to use for mobile data, select the Movistar eSIM (or leave it as a secondary line if you plan to continue using another as primary).
- Check the line name: by default, it usually appears as "eSIM" or with the operator's name; you can rename it to avoid confusing it with another line on the same phone.
- If the phone has two active lines (physical + eSIM, or two eSIMs), also confirm which line uses data and which uses calls, as they can be configured separately.
If after this process the signal icon is still blank or shows "No service," the problem is no longer with the phone's configuration but with the line on the Movistar network. Check the section on common eSIM problems before reinstalling anything, because deleting the profile and not being able to reinstall it is precisely what happens in the next point.
What to do if the QR code does not work or has already been used
An eSIM QR can fail for three reasons, and it's best to rule them out in this order before requesting a new one:
- It was already scanned before, on this phone or another. As explained above, the code is for single use: if it has been installed once, it will not work again even if the image looks intact.
- It expired. Activation QRs usually have a limited validity period from when they are generated; if too much time passed between Movistar sending it and you scanning it, it may have expired.
- It was scanned from the wrong place, for example from the regular camera app instead of from the mobile data settings menu. Some systems read the QR but do not recognize it as an eSIM profile if it is not opened from there.
Before contacting support, try the obvious: restart your phone and check again if the eSIM appears as an active line. It sounds basic, but it resolves most cases where the profile was installed correctly and the phone simply didn't pick it up in time.
If you've ruled out all three points and the QR still doesn't work, the next step is to ask Movistar, via the app, WhatsApp, or at a branch, to re-issue the code for that same line. There's no way to generate a new one from the phone: it's always issued by the operator.
What to do if the eSIM has no signal or data
With the profile installed and the line activated, if there's still no signal, check in this order:
| Symptom | Probable Cause | What to do |
|---|---|---|
| "No service" appears next to the line name | The line is not yet active on Movistar's side | Wait for operator confirmation or inquire about the status of the process |
| There is signal but no internet access | "Data mode" is assigned to the other line | Manually change which line uses mobile data in settings |
| Intermittent signal or drops automatically | The phone is still connected to a previously saved network | Restart the phone or disable and re-enable airplane mode |
| The eSIM disappeared from the list of lines | The profile was deleted or the phone was factory reset | Ask Movistar to re-issue the QR: it cannot be reinstalled without a new one |
A simple trick that often unblocks the connection: activate airplane mode for a few seconds and then deactivate it. This forces the phone to reconnect to the network from scratch, which is often enough for the eSIM to get a signal after installation. If none of this works, read the guide on how to install an eSIM step-by-step, which covers installation from scratch on different phone models.
How to check if your phone is compatible with Movistar eSIM
Not all phones come with eSIM, and among those that do, some models originally sold outside Argentina or with the phone unlocked by certain operators may have the feature blocked by software. Before requesting line activation, it's advisable to confirm two things: that the model supports eSIM and that it is unlocked (not operator-locked).
The list of compatible models changes with each operating system update, so instead of repeating it here, we keep it updated in the eSIM compatible phones guide. If you have never used an eSIM before, it's also worth reviewing what an eSIM is and how it differs from a physical card, as some settings change names depending on the manufacturer.
Common errors when activating an eSIM (and how to solve them)
Most activation problems are common across operators and are not exclusive to Movistar. This table summarizes the most frequent ones:
| Error | Why it happens | Solution |
|---|---|---|
| "Could not scan code" | Low light, other device's screen with low brightness, or QR compressed in a PDF | Open the QR in full screen with good lighting, or use manual entry with SM-DP+ data |
| "This QR code has already been used" | The profile was already installed on this or another phone | Request a new QR from the operator; there is no way to reuse the previous one |
| The phone does not offer the "Add eSIM" option | The model is not compatible or the phone is locked by another operator | Confirm compatibility and that the device is unlocked before insisting |
| eSIM installs but there is no data | The line is not active on the operator's side, or data mode points to another line | Verify the activation status and check which line has mobile data activated |
If you've gone through this list and the problem is still on the operator's side, that delay does not depend on your phone or how you installed the profile: it depends on their internal activation times.
Movistar Argentina eSIM vs. international eSIM for travel
Movistar Argentina is a local operator, designed for those who will have a daily use line within the country. For that, it works well. The complication arises when the person looking for the line is not a resident: activating a personal line usually requires local documentation and procedures that a foreign visitor passing through may not always have on hand, and the line is useless once the trip continues to another country.
If what you need is data connectivity for a trip (to Argentina, or to Argentina and then another destination), a travel eSIM solves that specific case without requiring a local line:
| Movistar Argentina (local line) | PuraSIM eSIM (traveler) | |
|---|---|---|
| Designed for | Residents with a permanent use line | Travelers who need data for the duration of the trip |
| Activation process | Usually requires local documentation and verification | Online purchase, no in-person process |
| Activation | Depends on the channel and operator activation | Approximately 1 minute once the QR is scanned |
| Use outside Argentina | Not applicable: it's a local line | Covers over 200 destinations if the trip continues |
| Support if something fails | Operator's own channels | 24/7 in all languages via email and WhatsApp |
If you are traveling to Argentina and do not yet have a local line sorted out, or if you have already tried with Movistar and the process got stuck due to documentation issues, the PuraSIM eSIM for Argentina can be purchased and activated without needing a local line in your name, with up to 180 days from purchase to activate it when you need it. To understand how it compares to other travel connectivity alternatives, you can also check eSIM vs. traditional roaming.
Frequently asked questions
Does Movistar Argentina eSIM work in another country?
No. It is a local line designed for use within Argentina. If your trip continues to another country, you need another line or eSIM with coverage in that destination.
Can I have Movistar eSIM and another travel eSIM at the same time?
Yes, most modern cell phones allow you to save multiple eSIMs and use one physical one at a time, as long as the model supports dual SIM. You just need to define which one uses mobile data at any given moment.
What happens if I lose the Movistar QR code?
You need to ask the operator to resend or re-issue it, via the Mi Movistar app, WhatsApp, or at a branch. It cannot be recovered or regenerated from the phone.
Do I need Wi-Fi to activate Movistar eSIM?
You need some type of internet connection (Wi-Fi or data from another line) to download the eSIM profile the first time. Once installed, the line already works with its own signal.
How long does it take to activate Movistar Argentina eSIM?
It depends on the channel and the status of the process with the operator: installing the profile on the phone takes minutes, but it may take longer for the line to be enabled on the network depending on how the activation was done.
Can I activate Movistar eSIM from outside Argentina?
Line activation usually requires local procedures, so it's best to resolve it before traveling or directly within the country. If you need data as soon as you arrive, a travel eSIM that activates from anywhere avoids this problem.
Which phones are compatible with Movistar eSIM?
The same models that support eSIM in general, provided they are unlocked. Check the updated list in the eSIM compatible phones guide before starting the process.
Conclusion
Activating Movistar Argentina's eSIM is, technically, scanning a QR code and installing a profile: the part that most often gets stuck is the one that depends on the operator (inactive line, expired or single-use QR, documentation procedures). If you followed the steps in this guide and the problem is still on Movistar's side, there's no point in wasting your trip waiting for activation.
For that specific case, PuraSIM's eSIM for Argentina activates in approximately 1 minute, without local line procedures, with 24/7 support in all languages via email and WhatsApp if something doesn't work. And if the trip continues to another country, the same account covers more than 200 destinations without having to repeat the registration process for each one. For a more complete overview of how to prepare connectivity for the entire trip, the definitive eSIM travel guide brings together the rest of the steps.
