Quick answer: If an eSIM is stuck on Activating, first check whether the profile has already been added to your phone. If the eSIM appears in Cellular or SIM settings and you have not yet reached a covered destination, Activating may be a normal waiting state. Do not delete it. If you see Unable to Activate eSIM, Couldn’t activate, or an installation error, check Wi-Fi, device compatibility, carrier lock status, whether the QR code has already been used, whether the provider has assigned the plan, and whether system and carrier settings are current. Delete the profile only after support confirms that it can be reinstalled.

“Activating” and “Unable to Activate” may look similar, but they can represent completely different failures.

A travel eSIM normally passes through at least four separate stages:

1. The eSIM profile is downloaded to the phone.
2. The eSIM line is enabled on the device.
3. The provider activates the plan.
4. The phone connects to a supported network at the destination.

If any stage is incomplete, you may see messages such as:

Activating
Unable to Activate eSIM
Unable to Complete Cellular Plan Change
Couldn’t activate
Network not activated
Activation failed

The first step is not to scan the QR code repeatedly. It is to identify which stage has failed.

Understand the four different states

1. The eSIM profile has not been added

Typical signs:

• No new eSIM appears in Cellular or SIM settings.
• The QR code immediately produces an error.
• The download never completes.
• The phone tells you to try again or contact the carrier.

This is primarily an installation or profile-download problem.

2. The profile is installed but device activation is incomplete

Typical signs:

• The eSIM appears in settings.
• The line shows Activating.
• You can see the label but there is no network.
• Turning the line on does not immediately change the status.

The phone may still be waiting for carrier or provider-side configuration.

3. The device line is enabled but the provider-side plan is inactive

Typical signs:

• You can turn the eSIM line on.
• The order page still shows inactive or pending.
• Manual activation is required.
• The selected start date has not arrived.
• The provider displays Activation pending or a similar status.

This is a plan-status problem and may not be fixable through phone settings alone.

4. The profile and plan are ready, but the phone has not reached a supported network

Typical signs:

• You are not yet in a covered destination.
• The phone shows Activating, No Service, or Searching.
• Registration is designed to happen after arrival.
• Plan validity starts with the first supported network connection.

This may be normal.

When can “Activating” be normal?

Activating may not indicate a fault when:

• The eSIM already appears in phone settings.
• The product allows installation before travel.
• Activation begins with the first supported network connection.
• You are still in your departure country.
• Your current location is outside the plan’s coverage.
• The order remains within its activation deadline.
• There is no explicit download or installation error.

In that case:

1. Do not delete the eSIM.
2. Keep the order and installation details.
3. Give the line a clear label.
4. Leave it off if the product instructions recommend doing so.
5. Turn it on after arrival.
6. Select it for mobile data.
7. Enable data roaming when required.
8. Wait several minutes for network registration.

When Should You Install and Activate a Travel eSIM?

Which messages usually indicate a real activation failure?

These messages require closer investigation:

• Unable to Activate eSIM
• Unable to Complete Cellular Plan Change
• This code is no longer valid
• eSIM cannot be added
• Network not activated
• Activation failed
• Plan already in use
• QR code expired
• Contact your carrier
• The download remains incomplete.
• The QR code is rejected immediately.
• The eSIM never appears in SIM settings.
• The order shows failed or expired activation.

Save the exact error text and a screenshot. “It does not work” is much less useful to support than the complete message.

Step 1: Confirm device compatibility and carrier-unlocked status

A product family may normally support eSIM while a specific regional model does not.

Check:

• Whether the phone has Add eSIM or Set up an eSIM.
• Whether the device displays an EID.
• The full model number and sales region.
• Whether the phone is carrier-locked.
• Whether work or school device management blocks adding cellular plans.

On iPhone, go to:

Settings → General → About → Carrier Lock

It should normally show:

No SIM Restrictions

For a complete compatibility check, read:

How to Check If Your Phone Supports eSIM

Step 2: Use a stable Wi-Fi connection

A phone normally needs internet access to download an eSIM profile.

Try the following:

1. Connect to reliable private Wi-Fi or a trusted hotspot.
2. Temporarily turn off VPN services.
3. Temporarily disable proxies, private DNS, and firewall apps.
4. Avoid airport or hotel Wi-Fi that still requires browser sign-in.
5. Make sure the phone has sufficient battery.
6. Open the eSIM setup screen again.

Do not repeatedly scan the QR code on an unstable connection. The provider may have accepted the first request even if the phone did not finish displaying the result.

Step 3: Check whether the eSIM was already added

An error can appear even though the profile has already been partially or fully added.

iPhone

Settings → Cellular

Check for a new line.

Samsung Galaxy

Settings → Connections → SIM manager

Google Pixel

Settings → Network & internet → SIMs

If the eSIM is already present:

• Do not scan the QR code again.
• Do not immediately delete the profile.
• Turn the line off and back on.
• Toggle Airplane Mode.
• Restart the phone.
• Check the status again.

If the profile is completely absent, continue with the QR code and provider-status checks.

Step 4: Confirm that the QR code is unused, valid, and assigned to this order

Many travel eSIM QR codes are single-use.

Common reasons for rejection include:

• The profile has already been installed on this phone.
• It was scanned on another device.
• It was installed and later deleted.
• The installation deadline has passed.
• The QR code belongs to another order.
• The image is cropped, blurry, or incomplete.
• The provider revoked or replaced the profile.

If you see:

This code is no longer valid
Plan already in use
QR code expired

stop scanning repeatedly. Ask support to confirm:

• Whether the profile is already bound to an EID.
• Whether the provider recorded a successful download.
• Whether the profile can be reissued.
• Whether a new QR code is required.
• Whether the original profile can be restored.

Do not upload the QR code to a public decoder website.

Step 5: Confirm that the provider assigned the eSIM

Some phones first ask the carrier or provider whether an eSIM is available for download.

If the provider has not generated, assigned, or activated the profile, the phone may:

• Find no plan.
• Search indefinitely.
• Display an activation error.
• Tell you to contact the carrier.

Check the order page for:

• Successful payment.
• An eSIM profile that has been generated.
• Issued QR code or manual details.
• No cancellation or refund.
• No pending manual review.
• No provider-side failed status.
• No binding to another device.

Google’s Pixel guidance also notes that when a SIM is not detected automatically, the carrier may need to activate the eSIM first.

Step 6: Check whether the phone has reached its saved-eSIM limit

Phones can store only a limited number of eSIM profiles. The exact limit depends on model, operating system, and region.

If many old profiles are stored:

1. Open SIM settings.
2. Identify expired plans that are definitely no longer needed.
3. Confirm that they have no remaining data or refund implications.
4. Remove only profiles you are certain you no longer need.
5. Do not delete the eSIM currently being troubleshot.
6. Try adding the new plan again.

Do not erase every eSIM just to free space.

Step 7: Update the operating system and carrier settings

Older iOS, Android, One UI, or carrier settings can interfere with profile download and activation.

Check for:

• iOS updates.
• Android updates.
• One UI updates.
• Google Play system updates.
• Carrier settings updates.

iPhone

Settings → General → Software Update

To check carrier settings:

Settings → General → About

Wait several seconds for a possible update prompt.

Use stable Wi-Fi and sufficient battery.

Step 8: Toggle the line, Airplane Mode, and restart

If the eSIM already appears in settings:

1. Turn the eSIM line off.
2. Wait about 30 seconds.
3. Turn it back on.
4. Enable Airplane Mode for 15 to 30 seconds.
5. Disable Airplane Mode.
6. Restart the phone.
7. Check the status again.

Apple’s current troubleshooting guidance also recommends turning the line off and back on when the number or plan already appears in Cellular settings, then restarting the device.

Step 9: Check registration after arrival

If the profile is installed but you are still outside the destination, do not assume No Service or Activating means failure.

After arrival:

1. Turn on the travel eSIM.
2. Select it for mobile data.
3. Enable data roaming when required.
4. Wait several minutes.
5. Toggle Airplane Mode.
6. Manually test a supported partner carrier when necessary.
7. Turn off Wi-Fi and test mobile data.

If the phone registers on 4G, LTE, or 5G but websites still do not load, use this guide instead:

eSIM Installed but Not Working? A Complete Troubleshooting Guide

iPhone stuck on Activating

Check whether the line exists

Settings → Cellular

If the line appears:

• Turn off Turn On This Line.
• Wait 30 seconds.
• Turn it back on.
• Toggle Airplane Mode.
• Restart the iPhone.

Apple may label this section Mobile Data in some regions.

Check Carrier Lock

Settings → General → About → Carrier Lock

It should normally show:

No SIM Restrictions

Check carrier settings

Settings → General → About

Wait for a possible update prompt.

Save the error details

Apple recommends having relevant information available when contacting the carrier, including the exact error, iPhone model, and device identifiers where requested.

Do not publish a full IMEI or EID. Share it only through a trusted support channel.

Samsung Galaxy unable to activate an eSIM

Check SIM manager

Settings → Connections → SIM manager

If the profile appears, turn it off and back on.

Power the phone off completely

Samsung support guidance for incomplete activation or SIM-status issues may include powering the device off, waiting about 30 seconds, and restarting it.

Check software updates

Settings → Software update

Confirm the installation route

Settings → Connections → SIM manager → Add eSIM

If the QR code has already been accepted, do not add the same plan again.

Reset mobile network settings only later

After saving Wi-Fi and APN information, a later step may be:

Settings → General management → Reset → Reset mobile network settings

Do not erase all data or downloaded eSIMs.

Google Pixel unable to activate an eSIM

Check whether the plan is already present

Settings → Network & internet → SIMs

If the eSIM appears, turn Use SIM off and back on, then restart the phone.

Recheck provider-side status

Google’s setup guidance notes that if an eSIM is not detected automatically, the carrier may need to activate or assign it first.

Confirm the setup route

Settings → Network & internet → SIMs → Add SIM → Set up an eSIM

Check updates

Check:

• Android system update.
• Google Play system update.
• Relevant carrier-services updates.

Reset mobile network settings only later

Settings → System → Reset options → Reset mobile network settings

If the screen offers to erase downloaded SIMs, leave that option unselected unless support has confirmed reinstallation.

When should you scan the QR code again?

Rescan only when at least one of these is true:

• The first scan clearly downloaded no profile.
• The eSIM is completely absent from SIM settings.
• Support confirms that the QR code remains unused.
• The provider issues a new QR code.
• Support explicitly instructs you to reinstall.

If the profile already exists, do not scan again.

When can you delete the eSIM?

Consider deletion only when:

• The plan has ended and is no longer needed.
• The provider confirms that it can be reinstalled.
• You already have a replacement QR code or manual details.
• Support explicitly instructs you to delete it.
• You are selling or fully resetting the phone.

Do not delete a profile merely because it shows Activating. If you have already deleted it, check out our eSIM Deletion Recovery Guide.

What not to try first

• Do not repeatedly scan the same QR code.
• Do not immediately delete the eSIM.
• Do not factory-reset the phone.
• Do not erase all eSIMs.
• Do not modify CSC, root the phone, or flash firmware.
• Do not use unofficial eSIM repair tools.
• Do not publish the EID, IMEI, ICCID, QR code, or activation code.

What to prepare before contacting support

Prepare:

• Order number.
• eSIM product name.
• Exact error message.
• Time the error occurred.
• Phone brand and full model number.
• Country or region where the phone was purchased.
• Operating system version.
• Whether the eSIM appears in SIM settings.
• Whether you have reached a covered destination.
• Whether the QR code was scanned on another device.
• Provider-side activation status shown on the order page.
• Screenshot of the error.
• EID or IMEI only when requested through a secure support channel.

Hide the QR code, activation code, ICCID, full IMEI, EID, phone number, and payment details in screenshots.

Frequently asked questions

How long can an eSIM remain on Activating before it is a problem?

There is no universal limit. If you are outside the covered destination, it may remain on Activating until arrival. If you are already at the destination and it still cannot register after basic troubleshooting, contact support.

Stuck on Activating after upgrading to a new phone?

If this eSIM was transferred from an old phone, it may not register with the network successfully even if the profile appears on the new device, due to provider restrictions. Check if transfers are supported or if support is required. For details, see Can You Transfer an eSIM to a New Phone?.

Does Activating mean the plan validity has started?

Not necessarily. The phone’s line status and the provider’s plan-validity status are separate. Check the product activation policy and order page.

Does Unable to Activate mean the QR code has expired?

Not always. Wi-Fi, carrier lock, regional model, provider assignment, or system issues can produce the same message. First check whether the profile was already added.

How many times can I scan an eSIM QR code?

Many travel eSIM QR codes can be installed only once. Do not assume that they are reusable.

The eSIM appears in the line list. Should I scan it again?

No. Turn the line off and back on, restart the phone, and check provider-side status.

Can I delete and reinstall it?

Only when support confirms that the profile can be recovered or a new QR code has been issued.

Why can’t my Pixel find the eSIM?

The provider may not have assigned the plan, the model may not support it, the phone may be locked, the network connection may be unstable, or the QR code may be invalid.

Why does my Galaxy keep searching for a plan?

Samsung may first search for an eSIM directly assigned by a carrier. For a travel eSIM, choose the provider QR code option. If it still fails, confirm provider-side status.

Do I need to factory-reset the phone?

Usually not. A factory reset is destructive and should not be part of routine travel eSIM troubleshooting.
