Also, please note that eSIM cancellation is not possible after purchase.<\/p>\n<p>&nbsp;<\/p>\n<h3><a id=\"Q0-2\"><\/a>How many days in advance should I apply for World eSIM?<\/h3>\n<p>There is no application deadline for World eSIM. You can apply right before you start using it. The eSIM validity period is 30 days, so if you don&#8217;t complete activation within 30 days, it will become unusable.<\/p>\n<p>&nbsp;<\/p>\n<h3><a id=\"Q0-3\"><\/a>Are there any coupon codes available?<\/h3>\n<p>There are no coupon codes for World eSIM. However, if you apply through our site&#8217;s exclusive special page, you can use all plans at 5% OFF.<\/p>\n<p>&nbsp;<\/p>\n<h3><a id=\"Q-1\"><\/a>Can I use hotspot?<\/h3>\n<p>World eSIM supports hotspot. However, if you use hotspot with a low-capacity data plan, your data allowance will be consumed quickly, and you&#8217;ll reach the speed limit.<\/p>\n<p>&nbsp;<\/p>\n<h3><a id=\"Q-2\"><\/a>What happens when I reach the data limit?<\/h3>\n<p>World eSIM applies data restrictions when you reach the specified data capacity. When you reach the data limit, speeds are reduced to a maximum of 128kbps, but the service doesn&#8217;t become completely unusable.<\/p>\n<p>&nbsp;<\/p>\n<h3><a id=\"Q-3\"><\/a>Is it okay to keep my regular SIM card inserted?<\/h3>\n<p>There&#8217;s no problem keeping your regular SIM card inserted when installing or using World eSIM.<\/p>\n<p>&nbsp;<\/p>\n<h3><a id=\"Q-4\"><\/a>What&#8217;s the difference between eSIM, rental Wi-Fi, and international roaming?<\/h3>\n<p>eSIM, rental WiFi, and international roaming differ in usage methods, pricing, and types\/numbers of compatible devices, with different recommendations for different people.<\/p>\n<p>&nbsp;<\/p>\n<h3>What is dual connection with eSIM and domestic SIM card?<\/h3>\n<p><a id=\"Q-5\"><\/a>With iPhone and Android, <span class=\"ymarker-s\">dual standby (simultaneous use) of physical SIM and eSIM<sup>\u203b<\/sup> is possible<\/span>.<a id=\"dual\"><\/a><br \/>\n<span style=\"font-size: 80%;\">\u203bLimited to eSIM-compatible devices.
