How to activate your Tigo eSIM on iPhone (quick summary)
To activate your Tigo eSIM on iPhone, go to Settings > Mobile Data > Add eSIM, and scan the QR code that Tigo sent you via email or SMS. The system will install the plan, and in a couple of minutes, you'll have mobile data working, provided you have stable Wi-Fi during the process.
If you already know exactly where you got stuck, jump directly to that section from the menu above. If you're starting from scratch, this is the order that solves the problem in most cases:
- Connect to a Wi-Fi network (do not use mobile data to install the eSIM).
- Open Settings > Mobile Data > Add eSIM and scan the Tigo QR code.
- Confirm the installation and choose if the eSIM will be your primary, secondary, or data-only line.
- Activate "Mobile Data" on that line, and if you're going to use it for browsing, deactivate roaming on your other line.
- Restart your iPhone if the plan installed but shows no signal.
The following sections detail each step and cover the two most common reasons this fails: the iPhone doesn't show the option to add eSIM, and the QR code doesn't scan.
Before you start: what you need to have handy
Before touching Settings, confirm these three things. They will save you most of the back-and-forth:
- The QR code or Tigo activation link. This usually arrives by email or SMS after contracting the plan. If you received it as an attached image, open it on the iPhone where you're going to install the eSIM: scanning it from another phone pointing at the first screen won't work, unless Tigo indicates otherwise in your case.
- An eSIM-compatible iPhone. Not all models support it; we'll cover this in detail below.
- Wi-Fi connection. The installation downloads a profile from Tigo's servers; attempting it with mobile data from another line may fail or get stuck halfway.
With this ready, the normal process is the same as for installing any eSIM on a compatible phone: the Settings screen is from Apple, not Tigo, so the steps are almost identical regardless of the carrier.
Step-by-step: install eSIM by scanning the QR code
This is the fastest method and the one Tigo uses most. With the QR code open or printed in front of you:
- Open Settings on your iPhone.
- Tap Mobile Data (on some models, it appears as Cellular).
- Tap Add eSIM or Set Up Mobile Data.
- Select Use QR Code.
- Point the camera at the Tigo QR code until the iPhone automatically recognizes it.
- Tap Continue and wait a few seconds while the profile downloads.
- When finished, name the line (e.g., "Tigo") to differentiate it from your physical SIM if you have another.
If the QR code is in PDF format or an image within the Tigo email, open it directly on the iPhone: when you have it on screen, Settings > Mobile Data > Add eSIM will give you the option to detect it without needing to use the camera separately.
Step-by-step: install using the manual activation code
When you cannot scan the QR (broken screen, damaged code, or you received it as text), Tigo usually provides an alternative: a manual activation code with the SM-DP+ data and the confirmation code.
- Go to Settings > Mobile Data > Add eSIM.
- Tap Can't scan? or Enter Details Manually.
- Copy and paste the SM-DP+ server address provided by Tigo (it usually starts with something like "rsp." or similar) into the corresponding field.
- Enter the associated activation code.
- Confirm and wait for the system to download the profile.
This method is more prone to typing errors than scanning a QR: check that you haven't copied blank spaces at the beginning or end of the code before confirming, as this will cause activation to fail without giving a clear reason on screen.
How to enable the line and activate mobile data
Installing the eSIM profile is not the same as activating it for browsing. Many people stop at this point thinking something went wrong when in fact a step is missing:
- Go to Settings > Mobile Data and confirm that the Tigo line appears in the list.
- Tap it and activate the Mobile Data switch for that line.
- If you have two active lines (your physical SIM and the Tigo eSIM), under Default Mobile Data, choose which one uses the internet by default.
- Check Automatic Mobile Data Switching: if activated, the iPhone can automatically switch between lines depending on the signal, which sometimes causes more confusion than help.
A setting almost no one checks that prevents unexpected charges: within each line, in Settings > Mobile Data > [line name] > Data Roaming, you can leave roaming off on the line you don't want to use outside your usual area, while keeping active only the eSIM that corresponds to where you are. This way, the iPhone won't end up using the wrong line for browsing even if both are technically installed and turned on.
If you need to send messages or make calls in the meantime, remember that you can keep both lines active for calls and SMS even if only one handles data: this is the normal logic of how an eSIM works compared to a physical card.
"I don't see the option to add eSIM": causes and solutions
If you don't see "Add eSIM" at all in Settings > Mobile Data, check these causes in this order, from most to least frequent:
- Your iPhone does not support eSIM. This is the most common cause. Check the compatible models table below before looking for the button further.
- The iPhone is locked to a carrier (partially unlocked). Some devices purchased with carrier financing restrict the use of lines from other providers, including eSIMs, until they are officially unlocked.
- You are already using two eSIM lines and your model only supports two active at a time (one physical + one eSIM, or two eSIMs depending on the model). You would need to delete a saved line to add the Tigo line.
- The operating system is outdated. A very outdated iPhone may not display the eSIM interface correctly. Go to Settings > General > Software Update.
- Device management (MDM) from a company that restricts profile installation. If the iPhone is corporate, this is often the real reason.
This type of blocking is not exclusive to Tigo: if you searched for another carrier and landed here, the logic is the same in how to activate a Claro eSIM on iPhone, because the failing step occurs on Apple's Settings side, not the carrier's.
Tigo QR code won't scan or gives an error
When the QR looks good but the iPhone doesn't recognize it, or it scans it and then shows an installation error, it's almost always one of these three reasons:
- The QR has already been used. Each activation code usually only works to install the profile once. If you tried to install it before and it failed halfway, the code may have already been "used up" on the server side even if nothing was installed on your iPhone.
- You are using mobile data instead of Wi-Fi to perform the installation. Switch to a Wi-Fi network and try again.
- Screen brightness or reflection prevents the camera from reading the code if you are scanning it from another device. Turn up the brightness to maximum and avoid direct light on the screen.
If the QR has already been used, the solution is almost never on your iPhone: you need to ask Tigo to resend or reactivate the activation code from their system. No phone setting can revive a code that the server has already marked as redeemed.
If the error persists after the code is resent, it may be a problem with the operator's server and not with the iPhone. It's worth identifying this before continuing to try: review the list of common eSIM problems and how to distinguish if the failure is with the phone or the provider.
Is your iPhone compatible? Models and requirements
Apple introduced eSIM in the iPhone line starting with the iPhone XS and iPhone XR. If your device is from that generation onwards, it is theoretically compatible, although final availability also depends on whether the model was sold unlocked or locked to a specific carrier in your country.
| iPhone Generation | Supports eSIM? | Note |
|---|---|---|
| iPhone XS, XR and older | XS and XR yes; older ones no | The XS is the first model with eSIM from Apple |
| iPhone 11 / SE (2nd gen.) | Yes | Dual eSIM available in some variants |
| iPhone 12, 13, 14, 15, 16 | Yes | Models sold in the US from iPhone 14 onwards do not have a physical SIM tray |
| Refurbished or second-hand iPhone | Depends | Check in Settings > General > About if an EID number appears; if it appears, it supports eSIM |
The most reliable way to confirm it on your specific device: go to Settings > General > About and look for an EID. If that number exists, the iPhone supports eSIM even if you have never installed one. For a more complete list by brand and model, including Android devices, check which phones are compatible with eSIM.
If the problem is still with Tigo: the alternative for travel
All of the above resolves the vast majority of installation problems when the iPhone is compatible and the QR code is valid. But if the Tigo code arrived damaged, expired, or the operator's support is slow to respond and you need a connection now (for example, because you are about to travel), the quickest way is not to keep insisting with the same QR: it is to install a separate data eSIM while the issue is resolved.
The practical difference between a local eSIM from an operator like Tigo and a data eSIM for travel is the scope: one connects you in a country or region where that operator has coverage; the other is designed for moving between several destinations without changing lines every time you cross a border.
| Local operator eSIM (Tigo) | International travel eSIM | |
|---|---|---|
| Coverage | A specific country or region | More than 200 destinations available depending on the plan |
| Contracting process | Depends on the local operator's process and availability | Online purchase and activation from any country |
| Activation time once QR works | Variable | Approximately 1 minute |
| Purchase code validity | Depends on the operator's policy | 180 days to activate from the purchase date |
| Support if something fails | Operator's own channels | 24/7 by email and WhatsApp, in several languages |
If what you need is simply to have data working on your iPhone while you sort out the issue with Tigo (or if you're going to travel through several countries on the same trip), installing an international data eSIM follows the same Settings process you saw above: you scan a QR code and in minutes you have a connection, without depending on the local operator to resend anything.
To better understand when one or the other is convenient depending on the type of trip, this comparison between eSIM and physical SIM reviews the fundamental differences between both formats.
Frequently asked questions
How do I enable my eSIM on iPhone after installing it?
Go to Settings > Mobile Data, tap the newly installed line and turn on the Mobile Data switch for that line. If you have another active line, you must also choose which is the default data line so that the iPhone uses the correct one for browsing.
Can I have a Tigo eSIM and another data eSIM active at the same time?
Yes. eSIM-compatible iPhones allow you to save multiple lines and use two simultaneously (e.g., one physical SIM plus one eSIM, or two eSIMs on models that allow it). Only one can handle mobile data at a time, but you can switch between them from Settings without reinstalling anything.
Do I need Wi-Fi to activate the Tigo eSIM?
Yes, it is recommended. The installation downloads a profile from the operator's server, and this process is more stable via Wi-Fi. Attempting it with mobile data from another line sometimes causes the download to fail halfway.
What do I do if I lost or deleted the Tigo QR code?
You need to request it again directly from Tigo, either through their customer service channels or by checking if the original activation email is still available. No iPhone setting can recover a QR code you no longer have.
Why does my iPhone say "Could not add eSIM"?
This message usually indicates that the QR code has already been used, that there is a temporary connection problem with the operator's server, or that the iPhone does not have space for another eSIM line. Review the error section above before trying again multiple times.
Does the Tigo eSIM work on any iPhone?
No. It only works on eSIM-compatible models (iPhone XS, XR and later) and provided the device is unlocked to accept lines from that operator. Check the compatibility table in this guide to confirm your model.
If I change iPhones, do I have to reactivate the Tigo eSIM?
Yes, generally an eSIM is associated with the device where it was installed. When changing iPhones, you need to transfer or reinstall the profile, which usually involves asking Tigo for a new activation code for the new device.
In summary
Activating a Tigo eSIM on a compatible iPhone is, in most cases, a three-minute matter: active Wi-Fi, Settings > Mobile Data > Add eSIM, scan the QR code, and activate mobile data on that line. When something goes wrong, it's almost always one of two things: the iPhone doesn't support eSIM or is locked, or the QR code has already been used and you need to ask Tigo for a new one.
If the problem is on the operator's side and you can't wait for them to solve it, you don't have to stay offline: an international data eSIM is installed with the same process you just saw, covers more than 200 destinations, activates in approximately 1 minute once the QR is scanned, and is available for up to 180 days from purchase to activate when you need it. If you also have questions during installation, support is available 24/7 by email and WhatsApp in several languages, so you don't have to keep trying the same broken code over and over again.
