What is an eSIM and how to get use of Yesim?

eSIM, or embedded SIM (the same as a digital SIM card, electronic SIM card, or virtual SIM card), is a cloud-based mobile number that allows users to activate and manage multiple cellular plans on a single device. It eliminates the need for a physical SIM card and provides the convenience of having multiple cellular providers on a single device. eSIM also offers additional features, such as the ability to add an extra line for traveling abroad and separate data plans for personal and business purposes.

How to activate eSIM mobile Internet from Yesim?

To connect to the internet using the Yesim eSIM: - go to Mobile Data settings; - turn on the Yesim mobile line; - activate Data Roaming; - choose Yesim Internet line as the main connection. Be sure not to select the "Remove Data Plan" option, as this will delete the eSIM profile.

Can I make phone calls or send SMS?

Our prepaid eSIM phone plans are designed for data-only solutions and do not come with a mobile phone number. To make voice calls and text communications, we recommend using VoIP apps such as Facebook Messenger, WhatsApp, Viber. This way, customers can stay connected globally without needing to buy a standard international SIM card from mobile operators, carriers, or providers for travel.

Is my device compatible with eSIM technology and the Yesim app?

You can only use Yesim on all compatible Apple and Android phones. Please check the full list of compatible devices (https://yesim.app/compatible-devices/) to check if your smartphone or tablet is eSIM supported. You can also check if your device supports eSIM technology by using this code: *#06#.

When does eSIM mobile data plan duration start?

The eSIM data plan duration will start right after the purchase is complete. If you are not planning to use your mobile internet right away, you can tap "Activate later" during the purchase of a new prepaid data plan and activate it during the next 12 months.

Can I get a refund for Yesim services?

Yes! Yesim offers refunds for eSIM data plans and top-ups purchased within 30 days of the purchase date. Refunds are not available for data plans that have been used or have expired. Ycoins are non-refundable, except in cases of confirmed technical malfunctions. To request a refund, please contact us via info@yesim.app (mailto:info@yesim.app) or use the contact form in the Yesim application. Our team will review your request and get back to you with further instructions. For more detailed information, please refer to our refund policy (https://yesim.app/refund-policy/).

Can I tether / use Personal Hotspot?

You can easily use your Yesim profile to share mobile data with other devices. All you need to do is install the Yesim profile on your device and turn on Personal Hotspot in the settings. This feature is enabled by default on your account, and there are no additional fees for using it, though any data used while tethered will be deducted from your plan.

Can an eSIM card be re-used?

Each QR code is a unique identifier that can only be used on one device. It cannot be reused on any other device or on the same device once the eSIM profile has been deleted. This ensures that the code remains secure and is used only on the intended device.

Can I extend eSIM cellular phone data plan expiration that I’m currently using?

You can do it easily. We'll send you a push notification and an email when you use up 70% of your data, so you can top up your Yesim account any moment from our app if necessary. The app will provide you with various payment options, making it easy to choose what is most suitable for you.

Ycoins are the internal coin and reward system used in the Yesim app. Your Ycoins balance is always shown in your selected currency for clarity and convenience. The value of your Ycoins is linked to the currency you choose when topping up (euro, dollars, pounds). If you later switch to a different currency, the balance is automatically converted. The amount you hold stays the same — only the currency display updates to match your preference and current exchange rate. You can use Ycoins to partially or fully pay for any data plan in the Yesim store, or to activate the Pay & Fly under the pay-as-you-go model. You can also invite friends to Yesim and earn Ycoins from their sign-ups and purchases. Get your referral link and find more details in the app.

Yes, eSIM technology is secure for several reasons. First, eSIMs are embedded directly into devices, making it difficult for unauthorized users to remove or tamper with them. Second, eSIMs utilize secure elements to store sensitive data, such as your mobile identity, which helps prevent hacking. Additionally, eSIM activation requires scanning a QR code or using a specific activation code, adding another layer of security. Overall, eSIM technology provides a robust and reliable way to ensure the security of your mobile communications.

How to transfer eSIM to a new phone?

Make sure to check that your new smartphone is compatible with eSIM technology before transferring your profile.

Don't forget to confirm that you are using a different device so that the settings can be updated correctly.

What is the difference between eSIM from Yesim and standard roaming data plans from physical mobile operators?

Why is my mobile internet data speed sometimes lower than usual?

The speed of mobile data can be affected by many factors, such as the type of smartphone you are using, the available network technology, the websites or applications you are accessing, the time of day, network congestion, other factors in the transmission path, and the cell tower's or area's data usage. Additionally, the download and upload speeds depend on the country's network infrastructure and boradband connection type. Low internet speed is usually caused by a mobile operator's poor coverage and can be remedied by rebooting your phone and sending us screenshots of the internet speed with and without LTE mode enabled.
