The Future of Connectivity is SIMless

The traditional SIM card in our mobile phones come with significant drawbacks: They lock us in to our mobile service provider and the connectivity is impacted by the availability and bandwidth of the  provider’s underlying network. When we travel outside the country, we pay exorbitant fees to our provider for data and voice roaming to have the same seamless connectivity we have at home. There are options to replace your current SIM with a local SIM (though you’ll lose the use of your home phone number while you travel) or put a new local SIM in a dual-SIM or spare phone, but all of these solutions involve cost, are inconvenient, or complex and, more importantly, make it difficult for you to connect to your home country.

Seamless global connectivity is still a distant dream. Over the top (OTT) players such as WhatsApp and Viber have made global connectivity slightly easier, but still require us to be connected to the ‘data pipe’. As eSIM technology takes off widely, global connectivity issues will be a thing of the past. The traditional SIM is linked to a single mobile provider. On the contrary, an eSIM is built into the mobile device and enables us to change or add one or more mobile operators over the air (OTA) without going to a mobile store or changing a physical SIM card.

eSIM enables out-of-the box connectivity of the device to a mobile network no matter where the device is deployed, enabling device manufactures like Apple, Google, and Samsung to bundle connectivity along with the phone. eSIM as a concept already exists with Google Project Fi and Apple SIM-enabled devices, but once eSIM devices are widely available, the technology will disrupt the entire mobile industry value chain, significantly impacting customers, device manufacturers, OTT players, mobile virtual network operators (MVNOs), and mobile operators.
