Avoid the connectivity mistakes that can compromise performance, increase costs and make IoT harder to scale.
Connectivity determines whether an enterprise IoT project can scale and how much it costs to keep it running. A flaw in its design or validation directly affects the entire deployment, whether in smart health devices, connected agricultural machinery, remote management of street lighting, mobile payment terminals, or energy sector infrastructure.
Scaling in IoT is also becoming increasingly complex. Within a single ecosystem, devices, modules, SIM or eSIM cards, profiles, network access points (APNs), networks, management platforms, and operational requirements all coexist and must function in a coordinated manner. In this article, we’ve summarized five critical errors that can compromise the viability of an Internet of Things project—errors that are easily detectable and resolvable with a proper testing phase prior to deployment. This scenario affects all types of devices across the wide range of IoT verticals.
5 mistakes in IoT projects you can spot before deployment
1. Assuming that the access technology will be available at the deployment locations
Not all networks offer the same access technologies. A device designed to connect via LTE-M or NB-IoT may lose service in countries where those technologies have not yet been deployed or do not provide the expected coverage, even if it has successfully passed initial lab tests. Before scaling up, it’s advisable to confirm, market by market, that the primary technologies for your IoT deployment are actually available where you need them, and to have a backup plan (such as 4G LTE) in place where they aren’t. In the specific case of LPWAN technologies (LTE-M and NB-IoT), there are tools that allow you to check the availability of the bearer in each region, but we recommend that you consult your connectivity provider directly, as there may always be nuances and specific details that only a company with extensive experience in IoT deployments can reliably interpret.
2. Choosing hardware that isn’t future-proof
Hardware selection should not be based solely on cost or availability. Verifying from the outset that devices and modules are compatible with the technologies required by the project and keeping pace with the evolution of networks and industry standards prevents operational problems and ensures that the deployment can scale without limitations.
The gradual phase-out of legacy technologies such as 2G and 3G in various markets underscores the importance of designing with a long-term vision, especially for deployments that must remain operational for years. Furthermore, using devices that do not comply with 3GPP and GSMA specifications can cause undesirable network behavior, such as continuous registration attempts or the generation of signaling traffic even after a SIM card has been deactivated.
In international projects, it is also essential to verify that the module supports the frequency bands used in all target markets. A device compatible with a technology such as 4G or LTE-M may not support the same bands in all regions, which would limit its ability to connect to local networks and require the use of different hardware versions depending on the country. It is also advisable to confirm that the device allows for the configuration of a private APN.
The cheapest option when deploying an IoT ecosystem often ends up being the most expensive over the course of its lifecycle. Verify with your connectivity provider that your hardware is ready to operate today, tomorrow, and the day after tomorrow wherever you need it.
3. Ignoring restrictions on permanent roaming
Certain countries and carriers limit or outright prohibit permanent roaming: a SIM card that remains connected to a network other than its home country’s for too long may suddenly have its sessions interrupted. In an international deployment intended to last for years, this poses a critical risk to business continuity. eUICC technology and multi-IMSI SIMs solve the problem: instead of relying indefinitely on roaming, you can remotely load a local profile wherever needed, without having to touch the device in the field. At this point, it’s important to remember that the value of an eSIM is directly proportional to roaming agreements and access to local profiles on the network that supports it.
4. Failing to verify compatibility between the SIM, the module, and RSP standards
eUICC technology has brought about a paradigm shift in global IoT deployments, but remote provisioning only works if the SIM, the module, and the platform speak the same language. Before manufacturing at scale, you must verify that the project’s SIM or eSIM is compatible with the chosen RSP standard (for example, SGP.32, the GSMA’s new standard designed for the IoT) and that the module supports it end-to-end. Otherwise, a profile change that seems trivial on paper becomes impossible once the equipment is deployed.
5. Ignoring regulatory and data sovereignty requirements
Roaming isn’t the only factor that varies from country to country. Each market imposes its own rules: device certification, data handling and storage, or sector-specific requirements. Designing a project with a single country in mind can create barriers just when it’s time to scale up. It’s critical to define the actual scope of the deployment from the start, taking into account not only the remote provisioning strategy and required profiles, but also regulations that could ultimately affect your equipment in the field — such as the CRA (Cyber Resilience Act), which impacts the entire lifecycle of equipment deployed in the European market.
What could go wrong?
When all these factors are not taken into account, errors can manifest in a wide variety of ways—ranging from equipment that is unable to connect to the network, either due to incompatibilities between different components or because the network is simply unavailable at the destination, to issues with network operators resulting from the use of unreliable hardware.
All these errors have one thing in common: they occur when connectivity is treated as a secondary consideration rather than a critical part of the project design. In a global IoT deployment, every element counts: the device, the module, the SIM or eSIM, the profile, the APNs, the bands, the access technologies, the standards supported by the hardware, and the reality of the networks in each country. If the entire ecosystem is not validated before scaling up, a seemingly minor problem can turn into an operational incident, an additional cost, or even the need to replace equipment that has already been deployed.
The value of testing: What device onboarding offers
For this reason, at Wireless Logic, we like to support our clients from the very start of the project. Our philosophy—“Design twice, deploy once”—encourages companies that come to us to review every detail of their implementation before putting it into the field. In this context, our Device Onboarding service is specifically designed to analyze the client’s equipment and perform the necessary testing to detect critical issues before it’s too late. It’s always better to find these types of errors in a prototype than in a deployment with thousands of devices already in the field.
How does our Device Onboarding process work?
We view onboarding as the phase in which we verify that a customer’s devices, modules, SIM cards, profiles, and APNs are ready for operation before scaling up. This is when we detect incompatibilities and issues early on, while they can still be corrected without operational impact and without having to replace equipment that has already been deployed.
For us, Device Onboarding is part of a broader strategy for critical IoT projects: it reduces the total cost of ownership and shortens time to market, while maintaining service availability as the deployment grows. In an increasingly global IoT ecosystem that is critical to business continuity, having a specialized partner reduces uncertainty and improves technical decisions from the outset, ensuring that devices operate reliably wherever the business needs them.
