what is cloud sim

Cloud SIM Technology

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 card of any operators around the world can be allocated to any users at anytime and anywhere. Consumers can gain access to best services provided by multiple local operators, in terms of coverage, experience and price.

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.

In some cases, the cloud SIM may automatically switch to a better performing Telco based on the device's location and the available network providers in the area. This feature is called "network roaming" or "network switching" and it allows the device to automatically connect to the best available network.

Unlike regular Roaming, locked to a single provider. Unnitel connects to multiple Tier-1 mobile provider operators in the same country to provide an enhanced customer experience through greater coverage range and data speed
