Permanent roaming is known for preventing the success of global IoT deployments. It’s one of the most difficult issues in M2M and IoT regulation with many left wondering how to solve permanent roaming issues for good.
Connectivity is fundamentally important to the success of an IoT project. The closer to 100% global connectivity, the better. Your IoT estate should have access to the highest quality of service and be connected to the best network available but solutions that rely on permanent roaming are now seeing their coverage eroded. Instead, we at Eseye achieve truly global connectivity through cellular network localization.
For enterprises with plans to deploy IoT devices across territories, permanent roaming can cause long-term issues. From extortionate roaming charges when data allowance is exceeded to, at worst, the device being ‘bricked’ and permanently suspended from the network, leaving IoT devices disconnected.
Permanent roaming issues that affect global IoT projects can be solved in a few different ways: by the solution provider establishing agreements with local mobile network providers, or by forming a relationship with a cellular network localization partner.
But sometimes these relationships break down. Roaming agreements and ties are cut, meaning that devices can no longer permanent roam. For example, some networks are unable to roam in North America or localize onto the USA’s largest 4G LTE mobile network operator, Verizon.
This is a major concern for customers: devices being deployed in the USA and trying to roam only on Verizon, for example, could be left completely disconnected from the network and unable to operate. A worst-case scenario actualized.
Localizing IoT Devices in the US
Cellular network localization is achieved when an IoT device connects to a mobile network operator native to the country it is deployed in. For example, if you have plans to deploy your IoT devices across multiple international borders the best option would be to localize each device so that they are not subject to permanent roaming regulatory restrictions.
How does it work? To localize your devices overseas, your IoT devices must use a Multi-IMSI SIM card (International Mobile Subscriber Identity) which houses multiple mobile network profiles.
In the case example below, the SIM has multiple profiles/bootstraps with different mobile network operators, including AT&T, T-Mobile, Sprint, and Verizon as well as other regional operators. The SIM rotates between these profiles to ensure that the device not only connects but achieves the best connectivity coverage available. If any network experiences issues or downtime, the SIM will rotate to another bootstrap profile – this is called a fallback and protects the device’s connection.
If a customer wanted to localize a device to Verizon, it would be as simple as pushing the Verizon profile over-the-air to the SIM and steering it onto that localized network to connect. Each customer IoT device deployed in the US will now be able to localize traffic directly onto the Verizon network, helping customers to end permanent roaming issues and improve latency speeds for a superior quality of service.
Global IoT Connectivity Relationships
Eseye’s IoT connectivity relationships enable customers to localize their IoT devices in the US and eliminate permanent roaming issues. Customers can access a wide range of localization partners who are all members of Eseye’s AnyNet Federation: the largest network of localization options available in the IoT connectivity market.
Our relationships enable customers the ability to connect and, where appropriate, localize their IoT devices to the widest range of networks, on power-up, via Eseye’s AnyNet intelligent IoT connectivity platform, which provides near 100% uptime globally.
Eseye achieves this through its unique AnyNet+ SIM. This advanced eUICC approach vastly simplifies the challenges of implementing global IoT deployment, accelerates the time to deliver business value, and futureproofs the solution as devices can be localized over the air at a later date if an interconnect becomes available for a specific country.
Nick Earle, CEO, Eseye comments: “Having the ability to localize devices in the US is a critical issue for customers around the world. The problem of permanent roaming has been a significant barrier for customers wanting to deploy reliable IoT solutions on a global scale. Now, Eseye customers can push past this barrier and localize devices seamlessly in the USA. At the same time, MNOs benefit from receiving quality traffic to their network. This delivers value to all parties, establishing a commercially beneficial way forward for MNOs and IoT customers alike,” adds Earle.
Using an intelligent, fully eUICC-compliant Eseye AnyNet Secure® eSIM, traffic can be steered towards AnyNet Federation MNO partners depending on the geographic location of the deployed IoT devices. Regardless of which AnyNet Federation partner delivers the IoT connectivity service, the customer receives one contract, one management view of their entire global IoT estate, and one single point of support.
