Frequently Asked Questions
An eSIM is a digital SIM card that has no physical form. It is embedded into a mobile device (such as a smartphone or tablet) that supports this technology and serves as a modern alternative to the traditional plastic SIM card. To use an eSIM, you need to connect to a mobile network operator.
Most modern mobile devices support eSIM technology, including models from both premium and budget segments. To check whether your smartphone is compatible with eSIM, refer to the official website of the device manufacturer.
Yes, this allows you to use one for personal needs and another for work, for example. It’s also convenient when traveling across multiple countries. However, the number of eSIMs that can be stored and used simultaneously depends on the specific device. You can find this information on the manufacturer’s website or by contacting technical support.
Just like a regular physical SIM card, eSIM allows you to connect to a mobile operator’s network, access the internet, use email, apps, online games, and popular messengers for quick messaging or calls. It is a full-fledged replacement for traditional SIM cards. However, it’s important to note that travel eSIMs work a bit differently: they don’t have their own phone number and provide mobile internet only. This means you can freely use messengers — make calls, send messages, and share files as usual. However, regular phone calls and SMS via the mobile network will not be available, since these plans are designed exclusively for internet access.
You can get an eSIM from your mobile network operator. You can also purchase one on our website or in the eSIM.World mobile app. We offer convenient data plans for 180+ countries — with high-quality internet access, but without a phone number.
In this case, it’s recommended to delete your eSIM profile. You can do this in the device settings. The same applies if you plan to give the device to someone else or sell it. If you experience difficulties, contact the device manufacturer’s support service or the mobile operator from whom you purchased the eSIM.
In this case, it is recommended to block the eSIM — just as you would with a traditional physical SIM card. Once the device is recovered and returned to the owner, the eSIM can be unblocked and used again without any restrictions.
If you’re using a travel eSIM, make sure to purchase a new eSIM in advance to avoid losing internet access.
Make sure you have selected, paid for, and added the eSIM plan in your device settings, that you’re currently within the coverage area of your selected plan, and that you’ve switched to the correct eSIM profile and enabled roaming in your device settings. If your eSIM doesn’t automatically connect to the mobile network within five minutes, you can connect manually. Go to your device settings, select your eSIM from the list of SIM cards, disable automatic network selection, wait a couple of minutes, and then manually choose an available network. If you need help connecting an eSIM purchased from us, please contact the eSIM.World support team via our mobile app or the live chat on our website.
When you format your iPhone, all data stored on the device is erased — including any eSIM profiles. You can reactivate the eSIM afterward using the QR code that was originally sent to your email during the initial activation. If the email was lost or deleted, your mobile operator’s customer support can help restore access.
