What is an eSIM?
eSIM stands for “embedded” SIM which is installed in your phone by scanning a QR code or tapping a notification. It is an easy way to use a new phone / data service when you travel abroad.
eSIM Advantages
- Easy to use: Set up your plan by scanning a simple QR code or tapping a notification.
- Save on Shipping cost: No physical delivery requirement
- Save on time: In a rush to travel? We will send eSIM QR Code via email. Scan it as per instructions and It will be ready to use upon arrival.
- Keep your original SIM: The eSIM is in addition to your original SIM which will work as usual if you need it.
eSIM Disadvantages
- Unfamiliar: Since it is a new technology expect to be learning a bit.
- eSIM Compatible Phones: eSIM will only work in eSIM compatible phones. As a general rule, iPhone 11 and Android model 2021 and higher models are compatible with eSIM.
- Single Use Only: Most eSIM codes can be used only once. Please do not delete the eSIM created on your phone, since it cannot be recreated on your phone or any other phone. However you can de-activate the eSIM when not needed from your settings.
- Transfer of eSIM: Once installed you cannot transfer an eSIM from one phone to another. However some USA eSIMs can be transferred from one iPhone to another.
Activating eSIM on your Device by tapping on Install Link (iPhone)
eSIMs can be conveniently installed on iPhones by tapping on the install link sent to you by our helpdesk by eMail. The install link must be tapped on the iPhone you intend to install the eSIM on. You need an Internet connection to install an eSIM.
Activating eSIM on your Device using a QR Code
Most eSIMs can be installed using a QR code which is sent to you by eMail. Simply point the camera of the phone you intend to install on at the QR code and click on the link that appears. In the rare case scanning directly by the camera does not trigger your phone to begin installation, follow the instructions below.
iPhone XR, XS and newer
- Go to Settings, then Cellular.
- Select Add a plan, and the Camera app will open.
- Point your camera at the QR activation code until you see a message that says Installing cellular plan.
2021 Android and newer
- Go to Settings > Connections > SIM card manager
- Tap Add mobile plan
- Tap Add using QR code
- Scan the QR activation code
Activating eSIM on your Device using an Operator Notification
T-mobile, AT&T and some other operators make it even simpler to install eSIMs. They send a notification directly to your phone on the activation date you choose. Just tap on the notification and follow the instructions as in images below. The notification is sent to the phone you intend to use on your trip for which you have given us the EID and IMEI number by dialing *#06#. Click here to know why IMEI and EID numbers are needed.

Trip to Scotland and Ireland. eSIM worked great for data and voice calls. Called the USA with no issues. Called local numbers with no issues. I know incoming callers worked because someone called me by mistake looking for the police. Data worked great also. However the reason for 4 stars was no texting worked. I didn’t expect incoming as no one had my new local number. Would it have worked? I can’t say but outgoing text attempts did not work. Failed everytime. Overall happy but the text issue needs to be fixed.

Very happy with the TSIM eSIM. I had used their physical sim in the past but this was the first time with their eSIM and it worked seamlessly. I used it in Sept/Oct 2025 for a 28 day trip to France, Italy, Slovenia, Greece (including Corfu) and Turkey without any issues. I plan on getting another one from them for my next trip in January

VERY pleased. I was surprised to learn that Turkey was not included with most European eSims. Nor, in some cases, Corfu. This eSim covered everywhere I needed to go in Italy, Greece and Turkey.
I got off to a less-than-prodigious start by mistyping my email address in my order, but Tsim’s Customer Service Chat was able to right my wrong. I am very pleased. Thank you Tsim!!

Thank you for your kind words and for pointing out a key benefit of this eSIM. Turkey is not part of the European Union (EU) and unlike this one, most eSIMs that claim to cover Europe actually only cover EU.

Worked great most of the time, but in my 16 day trip I had multiple days with no mobile data access at all. It was totally random as it would just stop working for 2-24hrs.

Thank you for your balanced review. We are in touch with the operator to find out what could cause this.

This was the first time I purchased an eSIM and I am happy to report everything worked as expected. I had no problems and will use Tsim.mobi again in the future.
