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.

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.

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 activate the Pay & Fly plan, which works for any country, and you will pay for the traffic you have actually used.

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.

Overall, eSIM technology provides a robust and reliable way to ensure the security of your mobile communications.
