  "account": "Determining whether a phone has eSIM capabilities is a common concern for customers before they complete a purchase. However, accurately detecting this feature can be challenging. There is no straightforward \"supports eSIM: yes/no\" signal that can be read consistently across different platforms.\n\nOn the web, there is no browser API that can definitively tell if a device has an eUICC chip, which holds eSIM profiles. While there are indirect methods, such as User-Agent strings or User-Agent Client Hints, these are not reliable for detecting eSIM capability. Many Android browsers have reduced the amount of model information in the User-Agent, and Safari and Firefox do not support User-Agent Client Hints at all. The customer may be using a different device than the one being tested, so detection should be considered a hint rather than a definitive gate.\n\nIn native apps, access to eSIM information is more available, but still limited. Android devices running version 9 or later can use EuiccManager.isEnabled() to check if an eUICC is available, but reading the EID itself requires special permissions. iOS devices have some capabilities, but in-app plan installation is often gated behind carrier entitlements, meaning most apps rely on Apple's setup link or QR code instead. Neither platform provides information about carrier locks, which can prevent a profile from being installed even if the device has an eUICC.\n\nThe most reliable way for customers to check eSIM compatibility is often for them to do so themselves. For example, dialing *#06# on many eSIM-capable phones will display an EID (Electronic ID) alongside the IMEI. If an EID is present, the phone has an eUICC. Customers can also look for an \"Add eSIM\" option in their device settings. Storing this information with the order can help resolve any compatibility issues that arise later.\n\nTo accommodate customers who may not know their device's capabilities, it's helpful to provide clear guidance and multiple options for checking eSIM compatibility. This could include a visible link to a compatibility check right at the plan selection stage, instructions on using dial codes or settings menus, and clear information about carrier locks. By making the process as straightforward as possible, you can reduce the number of support tickets related to eSIM compatibility and improve customer satisfaction.",
  "summary": "\"Does my phone support eSIM?\" is one of the most common questions a travel or fintech app gets right before checkout, and one of the most expensive to get wrong. A customer who buys a plan for a phone that can't take it doesn't just ask for a refund. They open a ticket, wait, and usually leave with a worse opinion of your brand than if they'd never bought anything. The frustrating part for…",
