To stay connected during travel, that typically means swapping device SIM cards upon arrival at your destination or being shocked by roaming charges upon return. It also means the uncertainty (panic) upon landing while hoping for a data connection to appear on your device or relying on your hotel wifi for service.
Global service, when built into a device, provides seamless switching between carriers in other regions without the threat of roaming charges. It equates to convenience, reliability, and security when traveling. While many mobile provider contracts allow users to take their phones from one country to another without an interruption in service, restrictions and limitations vary from country to country and from network to network. Roaming devices in countries with roaming restrictions will simply stop working. This means a user must go through the inconvenience of buying and physically inserting a new SIM card as well as re-provisioning the device for the new SIM. It’s a costly and time-consuming hassle. Additionally, of the existing IoT connectivity packages that may be ideal for roaming devices, almost all will run into problems if they encounter a network with permanent roaming restrictions.
Not all mobile devices are capable of working in all countries as cellular standards and frequencies vary around the world, and no phone supports all possible variations. The cellular frequency bands that are built into a device’s modem must be compatible with the surrounding mobile infrastructure. If the cellular frequency bands required in a specific region are not supported, the device’s modem will not work as well as it could or at all.
Having a device that is capable of supporting two SIM cards is one solution to achieve global service. Dual-SIM devices, such as the latest iPhone and Android models, have one physical SIM card slot and one embedded SIM (eSIM) that uses a downloadable profile rather than a plastic chip to connect to a cellular network. The eSIM technology makes it easier to switch networks and maintain connectivity regardless of geographic location. Rather than inserting a new SIM card into the phone, users can switch to a different network right from their own device.
SDM was an early adopter in the eSIM space and has incorporated an eSIM along with the industry-standard 4FF SIM card into the design of its secure dual-SIM device, allowing for global connectivity through a trusted partner that supports enhanced privacy capabilities.
The primary advantage, and the true meaning, of global service is uninterrupted connectivity regardless of location. Designed with zero-touch configuration, SDM’s dual-SIM device ensures your connection is automatic, seamless, and secure. And it provides more convenience and more privacy than your hotel lobby can offer.
