However, it does not require a physical medium and can be activated or reprogrammed remotely, without needing a card change.

This reduces the risks of theft or fraud through SIM swapping, a technique often used to hack bank accounts or online services.<\/div>\n<\/details>\n<details>\n<summary>Can an eSIM be transferred from one phone to another?<\/summary>\n<div class=\"answer\">Yes, but unlike a physical SIM card that can be moved from one phone to another in a few seconds, transferring an eSIM depends on the operator. Some allow easy transfer via their app, while others require a new activation with a QR code.<\/div>\n<\/details>\n<details>\n<summary>Does eSIM work in all countries?<\/summary>\n<div class=\"answer\">eSIM works in most countries, but this depends on operators and roaming agreements. Some eSIMs are designed for local use, while others offer global plans. At <a href=\"https:\/\/vostra.world\" target=\"_blank\" rel=\"noopener\">Vostra<\/a>, we offer eSIM plans tailored for international travel.<\/div>\n<\/details>\n<details>\n<summary>Do all mobile operators accept eSIM?<\/summary>\n<div class=\"answer\">More and more operators support eSIM, but it is not yet universal. Before switching to eSIM, it is advisable to check if your current operator or your destination&rsquo;s operator supports this technology.<\/div>\n<\/details>\n<details>\n<summary>What are the disadvantages of eSIM compared to a physical SIM card?<\/summary>\n<div class=\"answer\">\n<p>While eSIM offers many advantages, it does have some limitations:<\/p>\n<ul>\n<li>Transferring between devices can be less straightforward than with a traditional SIM card.<\/li>\n<li>Some operators do not yet offer eSIM support.<\/li>\n<li>If your phone is damaged, you cannot simply remove the SIM to use it in another device.<\/li>\n<\/ul>\n<\/div>\n<\/details>\n<details>\n<summary>How many eSIM profiles can be stored on a smartphone?<\/summary>\n<div class=\"answer\">This depends on the phone model. Most compatible smartphones allow you to save several eSIM profiles, but only one can be active at a time. On some devices, like recent iPhones, it is possible to activate two eSIMs simultaneously.<\/div>\n<\/details>\n","protected":false},"excerpt":{"rendered":"<p>The world of mobile telephony is constantly evolving, and with it, the technologies that allow us to stay connected.
