A cloud SIM, also known as a virtual SIM or eSIM, is a type of SIM card that is stored in the cloud and can be accessed via a mobile device or a SIM card reader. Instead of using a physical SIM card, a cloud SIM uses a digital version that can be provisioned and activated over-the-air (OTA) via a wireless connection. It allows a user to switch between different mobile network providers without having to physically change their SIM card.

Cloud SIMs can be used in a variety of devices such as smartphones, tablets, laptops, IoT devices, and more. Cloud SIM technology can provide a number of benefits when compared to traditional roaming. For example, cloud SIMs can allow users to automatically switch to a local network when traveling abroad, which can result in lower roaming charges. Additionally, cloud SIMs can allow for more flexibility when it comes to choosing a mobile network provider, as users can easily switch between providers without having to physically change their SIM card.

Cloud SIM is one of the best solutions available. SIM cards of any operator around the world can be allocated to any users at any time ...
... and anywhere. Consumers can gain access to best services provided by multiple local operators, in terms of coverage, experience and price.

A. Customer arrives in a new country and turns on their Unnitel Device

B. A unique virtual SIM Card is allocated to the Unnitel device from a local Tier-1 mobile operator

C. Data flow at 3G/4G rate is provided

D. When Device is powered off or leave the coverage area the virtual SIM is released

Cloud SIM Outperforms Roaming
Cloud SIMs can also help to ease the process of managing and provisioning SIMs for fleet management and IoT devices, because it eliminates the need to physically distribute, install and manage SIM cards. It also allows for over-the-air (OTA) updates, which can be useful in the case of security vulnerabilities or software bugs.

When a cloud SIM is assigned to a better performing Telco, it allows the device to connect to the mobile network with the best signal strength and coverage in the area. This can result in improved call quality, faster internet speeds, and more reliable connectivity.

The process of assigning a better performing Telco to a cloud SIM can vary depending on the provider, but generally, it involves selecting the desired network provider in a mobile application or web interface, and then activating the SIM card over a wireless connection.
