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.

You can buy a new data plan for any new country or region on the Yesim list and use it as many times as you need within the validity period. The only limit is the number of days and megabytes. You can also buy the International eSIM Plan, which works for any country, and you will pay for the traffic you have actually used.

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.

Your QR code is valid for one phone only and cannot be reused on additional phones. The same QR code can only be reused on the same device if the eSIM profile for this code is deleted from the phone.

Yes. You can keep using WhatsApp, SnapChat, Telegram or other messengers together with prepaid eSIM from Yesim.

To meet the high demands of our users, we at Yesim have developed unlimited plans to meet their needs. However, due to the Fair Usage Policy (FUP), after reaching a certain amount of provided data some speed reduction might be applied.

We provide thе following types of Unlimited Plans:

• Unlimited data plan for 7 days
• Unlimited data plan for 15 days
• Unlimited data plan for 30 days

After using the allocated amount of high-speed wireless data, users still have access to unlimited data. Fair Usage Policy allows users to use the internet for web browsing and emailing, providing uninterrupted access to online services at a lower speed.

These mobile phone eSIM plans offer unlimited data usage without any extra charges for exceeding the data limit. They are ideal for those users who need high-speed data access for posting photos, streaming videos, messaging, online gaming, and social media.

You can find unlimited eSIM data plans for each country in the Internet section of the Yesim app.

While such a data plan offers unlimited high-speed data usage, you should be aware that your data speed will not always be at its maximum. To prevent network congestion, most mobile service providers implement a daily usage limit. Once this limit has been reached, your data speed will be reduced, or "throttled."

To avoid throttling, it’s recommended to monitor your data usage regularly. Most smartphones have built-in tools that track your data usage; just check and adjust it accordingly.

You don’t need to sign any contract to use Yesim’s eSIM card. You can activate and deactivate it at any time, depending on your travel plans.

Yesim’s data plans are contract-free, with no roaming fees included. You pay only for the traffic you have used according to the eSIM data plan you bought.
