Understanding eSIM Technology


What is an eSIM?


An Embedded Subscriber Identity Module, or eSIM, also known as virtual SIM, is a compact, integrated chip embedded within your device, eliminating the need for a physical SIM card. This compact design not only streamlines the device's aesthetics but also opens up a myriad of possibilities for users.


How Does eSIM Work?


eSIMs operate by storing and managing subscriber profiles, enabling users to switch between carriers seamlessly. The process involves remote provisioning, allowing for greater flexibility and convenience, especially for frequent travelers or those seeking enhanced network coverage.


Advantages of eSIMs


  • Easy Flexibility: Swap carriers and plans effortlessly with eSIMs, eliminating the need for physical SIM changes.

  • Global Connection: Travel seamlessly with eSIMs, connecting to local networks worldwide without physical SIM cards.




Tascom Travel eSIM


Tascom offers virtual SIMs for 150+ countries, providing seamless connectivity without a physical SIM card. Users can flexibily choose from Local, Regional, and Global eSIMs with data plans spanning 7 to 30 days. As a whole they can experience swift and reliable data connectivity anywhere, allowing them to use data like a local.


Activation and Compatibility


What is an eSIM profile?


An eSIM profile is the information about the operator that’s required for the identification and authentication of a SIM card with a mobile network.

In the case of eSIMs, it comes in a digital version and must be downloaded by the user onto the chip on their device. Most devices can hold multiple profiles at the same time and the user can use them interchangeably.



Device Compatibility


It's crucial to ensure your device supports this technology. Most modern smartphones, smartwatches, and tablets now come equipped with eSIM capabilities, but it's always prudent to check your device's specifications.


How to Activate eSIM?


Activating an eSIM refers to the activation of eSIMs after they’ve been installed on the device. It is a straightforward process, often done through a carrier's mobile app or website. 

To put it into perspective with a real-life example, if a user goes on a holiday in July, they can purchase their travel eSIMs in advance, let’s say, in May. However, they should activate it only when they intend to use it. 

In this case, around the time of reaching their destination. If the plan bought with the eSIM has an expiration date, it’ll start counting towards that date from the moment the eSIM is activated.


Installing eSIM(s) On Your Device


There are two install options offered by TASCOM, either "install using a QR code" or "manual install". After a user purchases Tascom eSIM, the QR code will be emailed to the user.

Don't forget to turn on "Data Roaming" after install!

  • Reset network settings: If you are experiencing persistent connectivity issues, you can try resetting your device’s network settings. This will clear any saved network configurations and restore them to default settings. After resetting, you can set up all your network settings afresh, including your Wi-Fi password, APNs, and more.

  • Check data usage and coverage: Some eSIM data plans have limitations, so verify your data usage to ensure you have not exceeded the limit. Additionally, you should also check the coverage in your current location to ensure there is sufficient network signal strength.

  • Restart the device: Restarting your device will refresh all network connections, which could fix your eSIM connectivity issues.

  • Contact support: If any of the eSIM issues we shared persists, consider contacting your eSIM provider’s support. Tascom customer support is better positioned to provide specific troubleshooting guidance based on your device and eSIM configuration.
