If you experience problems,

If you experience problems receiving a signal or connecting to the internet, you may need to check a few settings or attempt to recover reception.

Here are a few ways to find out if you’re connected or reestablish signal:

  • Check if the roaming switch is OFF: Normally, a roaming switch is set to “OFF” when you’re not traveling abroad. If it’s switched off, your phone will not switch to your eSIM while you’re roaming. You can find it in the “Settings” of the phone
  • Reestablishing connection: If you’re having problems loading webpages or connecting to the internet, check to make sure you have enough signal bars for 3G or 4G/LTE. If you are in a functional coverage area and have tried all other fixes, you may need to complete a full power-down restart.

The problem has not been resolved yet? Feel free to contact our support team at any time.

Should eSIM roaming be set to "ON" or "OFF"?

When using Numero, your eSIM should have roaming “ON.”

You want Numero eSIM to make sure you’re connected to local network wherever you’re traveling. This way your device understands that Numero eSIM might be switching you from one network to another in order to deliver the best possible connection with no extra charge.

esim data

If you have a primary SIM (your regular number), roaming on that should be “OFF” while you’re using Numero, this is because you want to rely on Numero eSIM and not on your regular phone number.

esim data

To sum up:

Numero eSIM = roaming ON.

Regular SIM (if you have one) = roaming OFF.

I’m experiencing the ‘Unable to Complete Data Plan Change’ error message, what should I do?

The ‘Unable to Complete Data Plan Change’ error message is related to an installation failure which can be caused by different factors as follows:

  1. Many eSIMs are installed on the device. eSIM compatible devices allow you to install multiple eSIMs, but depending on the device model, the number of eSIMs you can have active simultaneously may vary. For example, iPhones can store from 5 to 10 eSIMs depending on the device’s storage. For more information, please contact your phone manufacturer.

 If you confirm that you have maximised your device’s eSIM storage. You can remove your old eSIMs on the device.

  1. Cellular/Mobile data is disabled in the device’s settings
  2. Trying to install an eSIM that was already installed: most eSIMs can only be installed once.

You can verify if the eSIM is installed on your device by Going to Settings > General > About > Scroll down to find the ICCID (it’s a 20 digits number that starts with 89XXXXXXXXXXXXXXXXXX and ends with a random extra number). If you confirm that the ICCID has been installed it might be a matter of making a few adjustments to get connected. Please refer to your eSIM installation page for all the details.

  1. Poor connection when trying to install the eSIM. This commonly happens when using the ship’s wi-fi or public wi-fi.

Try to follow the suggested solutions: 

I’m experiencing the “This code is no longer valid” error?

This error message appears when you are trying to add an eSIM that has been added before, or the QR-code was partially scanned due to poor connection.

In order to confirm whether the eSIM has been installed or not, please proceed as below:

  • Go to Settings
  • Go to General
  • Tap About and scroll down

If the eSIM is installed and turned on you should be able to view the ICCID [NUMBER] + an extra digit as long as the eSIM line is “On” under your Cellular Plans.

Please note that in case the eSIM has been removed and you attempt to reinstall it, it will not be possible!

On the other hand, if you are installing the eSIM for the first time, this error message could be due to a poor connection, VPN enabled, or too many eSIMs installed on the device.

Please follow the steps below to install your eSIM successfully:

  1. Disable any VPN
  2. Ensure that you have a good and stable internet connection 
  3. Remove any eSIMs you will no longer use
  4. Check if the software is updated to the latest version 
  5. Try to install an eSIM through an installation method different than before (Manually).

My data's turned on, but it's not working, what should I do?

If you switched Numero eSIM data ON and you can’t get to the internet, check the following:

Is “Data Roaming” switched ON for Numero plan?

Tap on Numero plan, and make sure “Data Roaming” or “Roaming” is switched to “ON.”

If data roaming is turned OFF, your eSIM just isn’t able to connect to a network and draw on the data. 

Note: If you have a primary SIM data plan, make sure that data roaming is turned OFF so that you wont get charged for roaming.

Is your device network-locked?

eSIM data plans can only be installed on devices that aren’t locked to a particular network. If you are seeing a message about “Cellular Plans From This Carrier Cannot Be Added,” please contact your carrier to have your device unlocked.

Have you activated your eSIM data plan and turned it on?

Check if your eSIM is activated properly, as the instructions are different depending on your device.

If you’ve confirmed all of the above, but you’re still not able to get a data connection, it might point to an outage. 

Please email: 

How do I make calls with a data-only plan?

You can easily make calls with data-only plan, you have two different methods to choose from:

  1. Make and receive calls over the internet using a service like WhatsApp, FaceTime, Messenger, Skype, Zoom, etc.
  2. You can also make and receive calls using your original mobile number, even while using an eSIM as your data connection.

With this option, your provider may charge you for calls and texts sent and received outside of your normal coverage area. (These charges will appear on your next bill, with phone calls charged per minute and texts charged individually.)

You can ask your carrier, prior to your trip, what they charge for calls and texts. Then you can make a decision on whether or not to use your primary mobile number while you’re away.

The good news is that using your Numero eSIM data will prevent you from racking up roaming charges, so you’ll have access to low-cost data that has nothing to do with your carrier.

How Many eSIM can I have?

Numero subscribers are welcome to buy as much data eSIM plans as they prefer. In other words, there is no ceiling to that. However, one Plan will be working at a time.

Where can I find my confirmation code?

Please check your purchased data package duration. Open Numero -> My Numbers & Data -> My Data -> Installation Guide -> View You QR or SM-DP+Address and Activation code

How long can I use my Numero data eSIM?

Open Numero -> My Numbers & Data -> My Data -> Select your data plan package and check the duration.

The package starts from the date of activation, but use starts when you connect to the new network in the country you are traveling to.

What can I do if I cannot scan my QR code?

In some cases regarding mobile camera dysfunctionality, users can install data packages manually using Numero SM-DP+Address and Activation code given to you once you purchase the eSIM data alongside with the QR code.

Why my eSIM has stopped suddenly?

Don’t panic, your device may have stopped for some reasons. Restart your device and all will settle down. For further inquiries, just send us and we will right there either through the app or through our email:
