Frequently asked questions

What is an eSIM and what are its benefits as opposed to a plastic SIM card?

An eSIM is an embedded SIM, which is included in selected types of devices in the form of a chip. An eSIM card supports all the services that you are used to with a regular SIM card. You no longer need to insert anything into your phone, you just simply upload a so-called eSIM profile into your device. Simply get connected to the internet or WiFi and prepare an eVoucher from O2, where you can find your QR code, PIN and PUK.

You can have two SIM cards active in one device at the same time. If your phone supports a plastic SIM card as well as an eSIM (iPhone from the XS model), it enables you to use both types at the same time. It means that you can have both your company and private number on the same device or you can use a tariff for calls and for data.

Visit your device manufacturer’s websites to find out if your phone supports an eSIM.

What is an eVoucher and where do I get it?

eVoucher is a voucher, where you can find your QR code, PIN, PUK, and the most important contacts in O2. It enables you do upload your eSIM profile onto your device.

You can get an eVoucher at all O2 Shops, where our O2 Gurus will be happy to help you activate it. If you are our customer, you can order your eVoucher in My O2. Simply choose the most comfortable delivery address – at home or at your office.

What is an eSIM profile?

Simply said, an eSIM profile is a collection of data that ensures your device functionality (in other cases this information is carried by a plastic SIM card). An eSIM profile is digitally saved on your eSIM card. It is connected to your phone number and your tariff is selected on it.

What should I do if I delete the recorded eSIM profile from my device by mistake?

If you delete your eSIM profile from the settings in your phone by mistake, you can upload it to your device again using your original eVoucher. That’s where you can find your QR code.

Don’t forget:

  1. When uploading an eSIM profile, your device needs to be connected to a WiFi network (this applies always, when you wish to delete or upload your profile).
  2. Restart or return of the device to factory settings should not erase your eSIM profile. (If you return your device to factory settings, you will be asked if you wish to delete everything, including your eProfile or not.)

  3. When your profile is deleted, your PIN code for the original settings is deleted too (unless you changed it yourselves). When you download the eProfile again, you have to use the PIN that is mentioned on your eVoucher once more. That is why we recommend you keep your eVoucher at a safe place.
What should I do if I need to get my device serviced?

If you need to get your device serviced, delete your eSIM profile from your phone. To delete it, you need to be connected to a WiFi network. If you encounter a problem when deleting your profile, simply visit an O2 Shop, where our O2 Gurus will be happy to help you.

If you manage to erase your eSIM profile from your faulty phone, you can use your current eVoucher to upload it again on a new device supporting an eSIM. If your back up device does not support an eSIM or you haven’t managed to erase your eSIM profile from the faulty device, your SIM card needs to be replaced (plastic or eVoucher).

What happens with the eSIM, if I lose my device?

The process is the same as if you lost your plastic SIM card:

Call the O2 Guru line at 800 02 02 02 and block your phone number as soon as possible. Then stop by at an O2 Shop and get a new eVoucher, which you can upload again on your new device. You can also order your eVoucher in Moje O2.

How many profiles can I have on an eSIM?

You can upload more eSIM profiles on your eSIM – for example one tariff for calls and a second one for data. The specific number depends on the capacity of the built-in chip on your device. Nevertheless, only one of the uploaded eSIM profiles can be active at one moment.
