At this year’s Mobile World Congress Las Vegas, we sat down with Robert Hamblet, the Founder, CEO & President of TEAL to discuss how TEAL; as an eSIM-first company, was well positioned to embrace the new market realities of SGP.32 remote SIM provisioning technology. TEAL is the first US-based eSIM platform to be certified by the GSMA providing a cloud-native, Credentialing-as-a-Service platform. They’ve boasted ES3 integrations with every major vendor and are virtually unmatched in interoperability as an eSIM first, connectivity second, company.
In this detailed interview, we discuss all the eSIM hot topics like:
- Credentialing as a service – CaaS covers a gap in the market for interoperability between platforms. Robert discusses G+D and Thales over Verison and AT&T; working together with the operator as a partner, not a competitor and how this allows for a future focus, preparing for the standards of tomorrow.
- Looking out for the needs of hardware OEMs – Previously, functionally has really just been about giving them an IP address through an MVNO with a SIM card that is hooked in with some existing connectivity supplier. Now, with SGP.32, there is flexibility. It can start from nothing and enrol in a platform after production with limited coordination between the enterprise and the operator.
- Concerns around SPG.22 – SGP.22 could see users stuck in a one-off environment that stagnates with the launch of SGP.32. It doesn’t even have a standard management interface like SGP.02(SMSR) or SGP.32 (eIM) does. Should you trust an unmanaged deployment on proprietary technology?
- Why OEMs would choose a CaaS provider – OEMs get product simplification where they can activate with an API call and not add a $2 increase to their bill of materials. That’s not to mention the value of direct relationships… customers want something straight from the source because of performance, reliability and pricing.
