It lets you add a mobile data plan without inserting a physical SIM card. Your device must support eSIM and be network or carrier unlocked. See our <a href=\"https:\/\/retesim.com\/compatible-devices\/\">Compatible Devices<\/a> guide before purchasing.<\/p><\/div><\/details>\n<details><summary>How does Retesim work?<\/summary><div class=\"rf-answer\"><p>Choose a destination, select a suitable data plan and complete your order. Once the order is successfully processed, you receive the information needed to install your eSIM. See the complete process on <a href=\"https:\/\/retesim.com\/how-it-works\/\">How It Works<\/a>, or start at <a href=\"https:\/\/retesim.com\/yesim-grouped-products\/\">All Destinations<\/a>.<\/p><\/div><\/details>\n<details><summary>How do I know if my phone supports eSIM?<\/summary><div class=\"rf-answer\"><p>Check your exact model, region and carrier variant in the manufacturer&#8217;s specifications, and look for an option to add an eSIM or mobile plan in your device settings. Model names alone are not always enough because regional versions can differ. Use our <a href=\"https:\/\/retesim.com\/compatible-devices\/\">Compatible Devices<\/a> page as a starting point.<\/p><\/div><\/details>\n<details><summary>Does my phone need to be unlocked?<\/summary><div class=\"rf-answer\"><p>Yes. Your device must be network or carrier unlocked so it can use an eSIM plan from another provider. If you are unsure, check with the carrier that supplied your phone before buying.<\/p><\/div><\/details>\n<\/section>\n\n<section class=\"rf-group\"><div class=\"rf-group-head\"><span class=\"rf-group-icon\">2<\/span><h2 class=\"rf-group-title\">Delivery and installation<\/h2><\/div>\n<details><summary>When will I receive my eSIM?<\/summary><div class=\"rf-answer\"><p>Our current integration sends the activation email after your WooCommerce order reaches Completed status and the eSIM processing succeeds. The email is not sent simply because checkout has started. If your order is completed but you cannot find the message, check your spam or junk folder and then <a href=\"https:\/\/retesim.com\/contact\/\">contact us<\/a>.<\/p><div class=\"rf-note\">We do not promise a fixed delivery time because successful processing must be completed first.<\/div><\/div><\/details>\n<details><summary>Where can I find my QR code and eSIM details?<\/summary><div class=\"rf-answer\"><p>The activation email generated by our current integration contains your order information, ICCID, an LPA code and a QR code made from that installation data. It may also show plan information when available. Keep this email safe and follow the instructions supplied with your eSIM.<\/p><\/div><\/details>\n<details><summary>How do I install my eSIM?<\/summary><div class=\"rf-answer\"><p>Open the mobile or cellular settings on your compatible phone, choose the option to add an eSIM and scan the QR code supplied in your activation email. Menu names vary by device and operating-system version. Follow our step-by-step <a href=\"https:\/\/retesim.com\/installation-guide\/\">Installation Guide<\/a>.<\/p><\/div><\/details>\n<details><summary>When should I install my eSIM?<\/summary><div class=\"rf-answer\"><p>Check the instructions and conditions for your specific plan before installing it. Activation rules can vary between plans, countries and network partners, so do not assume that every package should be installed at the same time. If the timing is unclear, <a href=\"https:\/\/retesim.com\/contact\/\">contact us<\/a> before installation.<\/p><\/div><\/details>\n<details><summary>When does my data plan start?<\/summary><div class=\"rf-answer\"><p>The start of the validity period is plan-specific. Depending on the package and network partner, it may begin after purchase, after installation, on the first connection to a supported network, or when several conditions are met. Review the information supplied for your plan and ask us before installation if anything is unclear.<\/p><div class=\"rf-note\">This cannot safely be described with one universal rule for every Retesim plan and requires plan-by-plan confirmation.<\/div><\/div><\/details>\n<details><summary>Do I need internet to install an eSIM?<\/summary><div class=\"rf-answer\"><p>Yes. Use a stable Wi-Fi or internet connection while adding and downloading the eSIM profile. Once installation is complete, follow the supplied instructions to select the eSIM for mobile data when appropriate.<\/p><\/div><\/details>\n<\/section>\n\n<section class=\"rf-group\"><div class=\"rf-group-head\"><span class=\"rf-group-icon\">3<\/span><h2 class=\"rf-group-title\">Using your eSIM<\/h2><\/div>\n<details><summary>Can I keep my physical SIM while using the eSIM?<\/summary><div class=\"rf-answer\"><p>Many compatible phones can keep a physical SIM active alongside an eSIM, but this depends on the exact device and its dual-SIM capabilities. Check which line is selected for calls, messages and mobile data. Your regular carrier may charge for services used through the physical SIM.<\/p><\/div><\/details>\n<details><summary>Can I use calls and SMS with the eSIM?<\/summary><div class=\"rf-answer\"><p>Retesim travel eSIM packages supplied through the current Yesim integration are data-only and do not provide a traditional mobile number for regular cellular calls or SMS. You can use internet-based calling and messaging apps with the data connection. Where your phone supports it, you may keep your physical SIM for normal calls and messages.<\/p><\/div><\/details>\n<details><summary>What happens if I use all my data?<\/summary><div class=\"rf-answer\"><p>The current package will no longer provide data after its included allowance has been used. Available next steps can depend on the plan, so we do not promise that every package supports a top-up. You can browse <a href=\"https:\/\/retesim.com\/yesim-grouped-products\/\">available eSIM plans<\/a> or <a href=\"https:\/\/retesim.com\/contact\/\">contact us<\/a> for help.<\/p><\/div><\/details>\n<details><summary>Can I reinstall or transfer the eSIM to another device?<\/summary><div class=\"rf-answer\"><p>Do not delete your eSIM profile if you still intend to use it. Reinstallation and transfer are not guaranteed, an eSIM normally cannot be active on two devices at the same time, and support can vary by provider and plan. Contact us before deleting the profile, resetting the phone or moving to another device.<\/p><div class=\"rf-note\">Transfer and reinstallation must be checked for the specific eSIM; they should not be promised as a standard feature.<\/div><\/div><\/details>\n<\/section>\n\n<section class=\"rf-group\"><div class=\"rf-group-head\"><span class=\"rf-group-icon\">4<\/span><h2 class=\"rf-group-title\">Support and refunds<\/h2><\/div>\n<details><summary>What should I do if the eSIM does not work?<\/summary><div class=\"rf-answer\"><p>First confirm that your exact device supports eSIM and is unlocked, that you had a stable internet connection during installation, and that the new eSIM is selected for mobile data when appropriate. Review the supplied instructions and our <a href=\"https:\/\/retesim.com\/installation-guide\/\">Installation Guide<\/a>. If the problem continues, <a href=\"https:\/\/retesim.com\/contact\/\">contact us<\/a> with your order number, device model and destination so we can check the specific plan.<\/p><\/div><\/details>\n<details><summary>Can I get a refund?<\/summary><div class=\"rf-answer\"><p>Refund eligibility depends on the Retesim <a href=\"https:\/\/retesim.com\/refund_returns\/\">Refund Policy<\/a>, the state of your order and whether the eSIM or data plan has already been installed, activated or used. Review the policy and contact us as soon as possible, preferably before installing or using the eSIM. The published Refund Policy takes precedence over this general FAQ answer.<\/p><div class=\"rf-note\">Final Retesim refund conditions still require business and legal approval before this answer can become a firm promise.<\/div><\/div><\/details>\n<details><summary>How can I contact Retesim?<\/summary><div class=\"rf-answer\"><p>Use our <a href=\"https:\/\/retesim.com\/contact\/\">Contact<\/a> page.
