esim Technology
Nomad Internet is America's largest WISP focused on providing wireless High-Speed Internet to rural communities all over the country! It is an eSIM store that solves the pain of high roaming bills by giving you access to eSIMs (digital SIM cards). With eSIMs from Nomad, download and install a digital data pack from 200+ countries/regions and be connected anywhere in the world the second you land.
CELLULAR CONNECTIVITY
For providing esims to travellers first we identified various cellular connectivity platforms which can manage the esims for us at the network level. We picked Telna for handling the esims for us at the celular level. We divided the esims into various regions. There were a total of three categories- Local, Regional and Global esims.
Local esims consists of regions based upon the various countries in the world. Regional esims have been divided into four regions like Asia, Europe, Africa and Caribbean Islands. Global esims cover all regions in the globe.
After finalising these regions we finalised the IMSI profile selection and purchased the esims. Each esim has an associated QR code which can be used by android and iOS mobile devices to activate any esim.
Admin Side
Architecturally we developed an admin panel using which we can import the esims sold by Telna and configure each and every region from this panel. All types of regions could be created, modified and removed from the panel. Admin panel was not just limited to creation of regions but can be used to handle users, stats and many more things.
On the mobile app the user can explore different types of esims based upon different regions. They can explore local, regional and global esims.
Users can get different types of top-up packages and can check different supported countries. They can purchase any package for the esim
esim Activation
After purchase of any esim it can be activated on the device either by using the native apis of the OS or by manually scanning the QR code of the esim. The esims work using the QR technology.
Using the Telna apis we can get the current status of the esim like the data used, expiry time and other information. Users can check all these info for their purchased esim in the mobile and web apps.
Conclusion
International travelers can enjoy the ease of purchase and installation that eSIMs bring – gone are the days of waiting in long lines to receive a physical SIM card, or paying exorbitant roaming fees by your primary service provider, or expensive prepaid SIM cards upon arriving at your destination.
