Is your Ubigi eSIM not working? This can be a headache, but there are different reasons this is happening, and some are easier to fix than others. So, don’t rush to delete your Ubigi eSIM just yet.

Read on to find the potential causes of your Ubigi eSIM’s failure, how to fix it, and, more importantly, an alternative solution that will give you peace of mind when traveling.

Common issues with Ubigi

If your Ubigi eSIM isn’t working, you’re likely to be struggling with one of the following problems:

  • Unable to connect or activate the Ubigi eSIM
  • Can’t access the internet on iOS and Android
  • Network not displayed on iOS devices
  • eSIM not transferred to iPhone

Let’s examine each one to understand why this is happening, and then we’ll focus on the solutions.

Unable to connect or activate the Ubigi eSIM

After scanning the Ubigi eSIM QR code, it’s possible that your phone won’t automatically connect. This can happen for two reasons:

  • You’re not in a location covered by one of Ubigi’s eSIM destinations.
  • It’s your first time using a Ubigi eSIM. If this is the case, you might simply have to wait a few minutes for things to roll out

This can also be a compatibility issue. Keep in mind that you can use one SIM and one eSIM if you have an iPhone SE (2nd generation), iPhone XR, iPhone XS, iPhone 11, iPhone 12, iPhone 13, and iPhone 14, and later. Dual eSIM function is supported on iPhone SE (3rd generation), iPhone 13, and later.

Can’t access the internet on iOS and Android

If you’re unable to access the internet on either an iOS or Android device, it is likely that you have an existing SIM or eSIM plan activated. Your Ubigi eSIM won’t work until your previous plan has been deactivated or removed as your primary plan.

Network not displayed on iOS devices

Upon activation, your Ubigi eSIM will become the secondary data plan on your iOS device. The Ubigi eSIM won’t start working on your iPhone or iPad until the primary line is deactivated.

The Ubigi eSIM operates as a secondary data line and requires manual network selection.

eSIM not transferred to a new or the same iPhone

If you’re moving to a new iPhone or restoring data to your current device, the eSIM won’t be transferred. You’ll need to set up or transfer the eSIM separately, either using Apple’s Quick Transfer feature (if your carrier supports it) or by reactivating the plan through your carrier.


If you’re transferring an eSIM from a non-Apple device to an iPhone, you’ll need to contact your carrier to complete the transfer. Some carriers support Android-to-iPhone eSIM transfers on iOS 26.

How to fix your Ubigi eSIM

There are a number of steps you can take to fix your Ubigi eSIM. While some address specific problems, most are general solutions that can help regardless of the symptoms you are seeing.

Check device compatibility

Before purchasing, ensure your device is compatible with the Ubigi eSIM to avoid issues. Ubigi refunds don’t apply for eSIM incompatibility

Here’s what you need to do to check the eSIM-compatibility:

  • Choose your preferred Ubigi eSIM.
  • Press on “Check eSIM compatible devices”.
  • Browse the available iOS, Android, and Windows devices before purchasing.

If your device is not listed, avoid purchasing a Ubigi eSIM, or you can contact customer support to double-check compatibility.

Check which eSIM your device is using

If, after installing the eSIM, the Ubigi data is not working, here’s what you need to do to switch from your previous SIM/eSIM to your travel plan:

  • iOS:
    • Go to “Settings”.
    • Tap Cellular (or Mobile Data).
    • Tap Cellular Data.
    • Select your Ubigi eSIM as the active data line.
  • Android:
    • Go to “Settings”.
    • Press on “Connections”.
    • Choose “SIM card manager”.
    • Press on “Mobile data”.
    • Change to your Ubigi eSIM and accept the changes.

Check network compatibility

If your Ubigi eSIM is up and running – on Android or iOS – but is unable to connect to the internet, here’s what you need to do:

  • Go to “Settings”.
  • Choose “Cellular or Mobile data”.
  • Go to “Data plans” and choose your Ubigi eSIM.
  • Press on “Network selection” and deactivate the automatic option to do a manual search.
  • After a few seconds, choose the “Ubigi” network or choose the available network displayed on the product page for the Ubigi eSIM you purchased.

Reinstall your eSIM on Android and iOS

As mentioned above, Apple has a limitation when transferring eSIMs. Here are some steps to follow when restoring or transferring an eSIM to your device.

Restoring or transferring data to the same iPhone or Android:

  • Delete your eSIM profile before moving to the transfer or data-restoring process.
  • After restoring or transferring, download the Ubigi app and log in to your account.
  • Once in, go to the “Settings” menu and choose “eSIM”, and then click on “Re-install my Ubigi eSIM”.
  • Follow the instructions on the screen to complete the installation process for your eSIM.

Restoring or transferring data to a new or different iPhone or Android:

  • If you have access to your previous device, make sure to delete your Ubigi eSIM profile or contact Ubigi customer support to get help if you don’t have access to your old device.
  • Download the Ubigi app on your new device and log in to your account on your new eSIM.
  • Go to “Settings” and then choose “eSIM” and click on the “Re-install my Ubigi eSIM”.
  • Follow the instructions on the screen and complete the eSIM installation on your new iPhone or Android device.

Basic solutions

If any of the previously mentioned solutions don’t work, here are some basic solutions you can try:

  • Check your 3G and LTE networks are activated on your Android or iOS device mobile networks.
  • Turn on and off the airplane mode and wait until the data starts working.
  • Restart your smartphone or tablet in case there’s a background issue happening.

  2. Go to Settings > Connections > SIM card manager.
