The IoT Connectivity Health Check: 7 Essentials for 2026

The days are getting shorter, and the temperatures are dropping. It’s flu season, and that means time for a quick health checkup – for yourself, and for your IoT fleets. An apple a day may keep the doctor away, but what happens when it's time to care for the Apple devices themselves?

1. Can every device get connected?

This is the basic fitness test that any IoT network first needs to pass, no matter how large or sophisticated it may be. State-of-the-art IoT fleets with AI-powered operations and automated processes are still useless without a reliable connectivity source. When assessing fleet readiness, the first step must be to ensure that all devices have a viable wireless connection that consistently delivers a reliable source of connectivity, regardless of the device’s location.

Global IoT requires broad cellular availability plus multi-network resilience and automatic failover, rather than dependence on a single carrier.

For IT admins, it’s essential to check that their fleets have satisfactory coverage in all countries of operation, as well as the ability to expand into new coverage zones as the business changes. An international IoT partner, with a single connectivity agreement for all countries, beats negotiating individual roaming contracts for every new market.

2. What happens when connectivity is business-critical?

Once connectivity is established, it’s necessary to check what happens when it is lost. A connected fleet is only of use when it’s resilient – that is, protected against potential network errors, signal failures, or outages.

In 2026, resilience is more important than ever. Not only are IoT fleets expected to perform across borders in service of an increasingly globalized economy, but the rate of cyberattacks against businesses is rising. Outages are harmful to any IoT company – in certain industries, however, they can be catastrophic. The risk of downtime must be managed to be as close to zero as possible.

The telehealth sector relies on flawless wireless connectivity to provide essential healthcare, with systems designed around a “zero-failure” concept.

Less life-threateningly, but still important, are retailers. Connected point-of-sale (POS) terminals need constant uptime during peak hours to ensure a smooth customer experience. Traffic in hospitality and retail POS is notoriously inconsistent – connectivity must be built to withstand spiking traffic and sales periods, not average usage. It’s also when payment outages are most likely to occur. A 2026 study of German consumers found that over a quarter of shoppers will abandon their purchase in the case of a POS outage. Even in a relatively cash-oriented society like Germany, where stores may revert to paper money during a network outage, downtime costs the retail industry an estimated €1.5 billion a year in lost revenue. The same report suggests this issue will only become more acute, as younger shoppers are even less likely to carry cash. The physical retail industry is notoriously volatile: stores can no longer afford avoidable risks like POS outages.

1GLOBAL's IoT POS proposition, for example, uses multi-network connectivity and redundant IMSI for failover network attachment route to maintain transaction readiness if primary connectivity is disrupted. Many IoT providers maintain single operator agreements: if the network fails, even briefly, so will all connected devices. Some providers offer two, providing a single fallback option. 1GLOBAL guarantees availability of a redundancy on the SIM and core network levels, with a minimum of three available networks in the main global markets and economies. Not only does this double-lock against downtime, but it allows devices to always connect to the fastest local network, delivering consistently high connectivity speeds across the entire device fleet.

3. Is device management an ongoing process?

One of the great advantages the eSIM brought to the IoT is the ability to manage device fleets without needing to manually switch SIM cards. A key drawback of SIM cards is that connectivity needs can, and do, change after installation. IoT teams need to provision, activate, and retire connectivity without physically accessing thousands of devices.

This is due both to rising demand and the eSIM-enabled efficiencies that make it possible to manage new fleets as needed. Anticipating this need, the GSMA released SGP.32 in April 2025. The standard solves this issue by enabling truly wireless, at-scale communication between IT admins and devices. Previous standards, like the consumer-oriented SGP.02, would always require two-way communication between device and manager: if the IT admin wanted to send out an eSIM profile, there would have to be a dedicated project of Remote SIM Provisioning platforms interconnecting. While this works for huge market players, for many IoT deployments, the use of SGP.02 is not commercially viable. SGP.32 eliminates this need for integration, allowing IoT companies to remotely “push” SIM profiles with the help of interoperable eIM solutions as simple as install via QR code on a smartphone, anywhere around the world, at scale, anytime.

For IoT companies to reap the full advantages promised by SGP.32, they require an equally up-to-date management platform. Remote management is only effective when teams have a viable digital tool through which to conduct it. SGP.32 provides the remote connectivity control mechanisms, while the management platform creates the operational intelligence and automation that make those mechanisms commercially vluable.

In doing so, SGP.32 enables a new generation of intelligence device management capabilities. Combined with device telemetry, connectivity analytics, and automated policies, IoT companies can build solutions that dynamically switch connectivity profiles in order to optimize network performance and costs, and orchestrate firmware updates using dedicated connectivity profiles. At the same time, disruption to users is minimized, and operators can automatically recover from network failures by activating alternative profiles while adapting connectivity as devices move across networks or countries.

The 1GLOBALeSIM IoT Manager (eIM) functions as the new lifecycle control layer, giving enterprises greater freedom to manage profiles remotely and reduce the operational constraints associated with physical SIMs and legacy provisioning.

4. Does the connectivity supply match the device?

An always-on POS terminal handling complex requests has completely different requirements from a battery-powered sensor that’s occasionally required to send a few bytes. So why treat them the same?

An IoT strategy needs connectivity appropriate to bandwidth, mobility, power consumption and device lifespan. That means considering everything from 5G to low-power LPWAN requirements, rather than applying a blanket model to every device. Energy optimisation is “critical for balancing functionality with efficiency” in the IoT. 1GLOBAL offers profiles designed for different IoT requirements, including low-power alternatives and critical multi-network deployments. The breakneck pace of the current IoT sector requires operators to keep one eye on the future, ready to adapt the location, size, and function of their fleets as needed. ESIM-enabled remote management is one solution. Flexible connectivity provisioning is another. A supplier who can cover a range of fidelities, from LPWAN to 5G (and eventually, 6G and 7G), allows clients to cover these bases, while also ensuring that they’re not paying for bandwidth they don’t need and contributing towards a more sustainable industry.

5. Is connectivity part of the workflow?

As previously alluded to, a successful IoT business is one that’s primed for the imminent surge in demand. Companies should conduct all operations with one eye on the future, building a connectivity strategy that can grow to match demand.

Maintaining efficiency while scaling IoT fleets into more countries requires a state-of-the-art digital platform that can incorporate automated processes and rules to ease workload for IT teams. At a certain point, manual processes will no longer suffice. Integrating automation, while retaining full oversight, is the next step.

A fully integratable API like the 1GLOBAL IoT stack provides this heavy-duty automative capability, while merging with existing management platforms to provide IT teams with a familiar UX.

APIs should connect your telecom layer with your own device, fleet, and operational platforms. When applied correctly, they can automate responses to events such as abnormal usage or changes in location, and make connectivity part of the existing workflow rather than another administrative task.

6. Can you see what your devices see?

Being prepared to scale is one thing – knowing where, how, and by how much is quite another. Strategic decisions must be based on strong evidence and informed insights. The best IoT analytics are based on up-to-the-minute data gathered from existing fleets.

Predictive maintenance is a clear example of this in action: well-managed IoT fleets that continually communicate their status with a central management platform allow teams to spot abnormalities and address potential issues before they occur. Real-time visibility helps teams to make better operational decisions before problems result in costly site visits. Again, a single centralized platform makes this possible: raw data from worldwide operations is concentrated and presented in a workable UX that allows teams to focus on decisions, rather than scanning terabytes of data.

7. Does the commercial model scale as well as the hardware?

Analysts predict the number of IoT devices worldwide will grow by over 60% by 2030 – that's nearly one per person on Earth. IoT companies must consider what happens when 1,000 devices become 100,000. Businesses need visibility into usage, the ability to activate and suspend connections, shared allowances where appropriate, and pricing models aligned with how their devices actually consume data. A scalable connectivity strategy must be tied to a scalable pricing model.

1GLOBAL currently offers prepaid, pay-as-you-grow, shared and flexible IoT plan structures. These are built around our history of working with IoT companies through a massive market shift.
