The validity period of an eSim card can vary depending on the mobile network operator and the specific terms and conditions of the eSIM plan. Generally, the validity of an eSIM is determined by the duration of the subscription or plan associated with it. This could range from a few days to several years, depending on the service provider and the type of plan chosen.

Some eSIM plans may have a fixed duration, such as a monthly or annual subscription, while others may be prepaid with a specific validity period, often measured in days or weeks. It's essential to check with your mobile network operator or service provider to know the exact validity period of your eSIM plan.

It's worth noting that eSIMs are programmable and can be remotely provisioned and reprogrammed, allowing users to switch between different network operators or plans without needing to physically change a physical SIM card. This flexibility makes it easier to update or extend the validity of an eSIM plan, as long as the service provider supports it and the user has an active subscription or credit.
