- Improving data visibility (hourly or daily reporting)
- Enhancing customer satisfaction (transparent billing and leak alerts)
- Complying with national smart metering regulations
- Building scalability for millions of future connections
When utilities clearly define these goals, the technology selection becomes data-driven rather than vendor-driven.
2. Step 2: Assess the Deployment Environment
Each country, region, and even city has unique environmental and network conditions.
Your communication choice must fit those realities.
2.1 Urban vs Rural Deployment
- Urban: Dense populations, strong cellular networks, high interference → NB-IoT or LTE Cat-M are preferred.
- Rural: Sparse density, limited coverage → LoRaWAN or NB-IoT may work better.
2.2 Installation Location
- Indoor / Basement meters: Require strong penetration → NB-IoT excels.
- Outdoor / Rooftop meters: LTE Cat-M or 4G/5G may perform well.
2.3 Power Availability
- Battery-powered meters: Choose LPWAN (NB-IoT / LoRaWAN).
- Powered gateways or hybrid devices: LTE/4G/5G options are possible.
2.4 Regulatory Context
Some countries have mandated LPWAN standards for smart utility projects.
For example:

This centralization ensures your IT team doesn’t need to manually manage each SIM — saving thousands of man-hours annually.
5. Step 5: Analyze Total Cost of Ownership (TCO)
A short-sighted decision based on initial SIM price often leads to higher long-term costs.
True evaluation must include:
- Hardware cost (modules, SIMs)
- Network fees (data plans, roaming)
- Maintenance and support
- Battery replacement cycle
- Data management and platform integration
Illustration Example:
Let’s assume a utility plans to deploy 500,000 smart meters.

Key Comparison: IoT SIM vs. LoRaWAN vs. NB-IoT for Gas Meter Communication
Choosing the optimal communication solution for smart gas metering requires a detailed understanding of three dominant connectivity options: IoT SIM (cellular-based), LoRaWAN, and NB-IoT. Each technology offers distinct advantages and trade-offs across critical parameters such as coverage, data reliability, cost, integration complexity, scalability, and maintenance requirements.
In this section, we’ll break down each factor so decision-makers in gas utilities can make the right long-term choice.
1. Coverage and Network Availability
IoT SIM Cards:
IoT SIM solutions leverage the existing cellular infrastructure — 2G, 3G, 4G LTE, 5G, NB-IoT, and Cat-M — to provide near-global coverage. This means gas utilities can deploy smart meters across urban, suburban, and rural regions without needing to build private gateways or networks.
Providers like Zhongyi IoT offer multi-network roaming SIMs that automatically connect to the strongest available carrier, ensuring uninterrupted communication even in areas where a single operator has weak signal strength.
LoRaWAN:
LoRaWAN, by contrast, relies on private or public gateways to connect devices. While it offers excellent coverage in local or regional deployments, it’s limited by the availability of gateways. This makes LoRaWAN better suited for city-level or utility-managed networks but less effective for large-scale or cross-border deployments.
NB-IoT:
NB-IoT sits between these two extremes — it uses licensed spectrum within the cellular infrastructure, providing better coverage and reliability than LoRaWAN but requiring carrier support and specific module compatibility.
Verdict:
If your company needs nationwide or international connectivity, IoT SIM is the most practical choice. For localized utility operations, LoRaWAN can still be cost-effective.
2. Power Consumption and Battery Life
LoRaWAN:
LoRaWAN devices are well known for their ultra-low power consumption. Smart gas meters using LoRaWAN can often run on a single battery for 10+ years, making it a strong contender for long-term, maintenance-free deployments.
IoT SIM (4G/5G):
Traditional cellular modules consume more energy due to frequent signal handshakes and higher transmission rates. However, modern IoT SIM solutions support power-saving features like PSM (Power Saving Mode) and eDRX (Extended Discontinuous Reception), enabling battery life of 5–10 years for low-traffic applications like gas metering.
NB-IoT:
NB-IoT excels here — it’s optimized for low-bandwidth, long-latency communication, combining cellular reliability with LoRa-like power efficiency. NB-IoT-based gas meters can operate for up to 10 years under optimized conditions.
Verdict:
For ultra-low-power environments, LoRaWAN or NB-IoT are best. But for scalable deployments with higher bandwidth requirements, IoT SIM remains competitive when using PSM/eDRX.
3. Data Transmission and Reliability
IoT SIM:
IoT SIM solutions offer guaranteed data transmission over licensed cellular networks, which ensures minimal packet loss and high reliability. This is especially critical for billing, leak detection, and real-time monitoring applications in gas utilities.
Moreover, with 5G and LTE-M networks, data speeds are sufficient for advanced analytics and firmware updates.
LoRaWAN:
LoRaWAN uses unlicensed spectrum, which can be subject to interference and message loss, particularly in dense urban environments. The network also has limited bandwidth, restricting real-time communication or large payloads.
NB-IoT:
NB-IoT strikes a middle ground — it provides better reliability than LoRaWAN but lower throughput than traditional LTE IoT SIMs. It’s ideal for periodic data uploads rather than continuous communication.
Verdict:
When data accuracy and reliability are top priorities — for example, in utility billing systems — IoT SIM provides unmatched consistency.
4. Cost Efficiency and Scalability
LoRaWAN:
LoRaWAN can be cost-effective when utilities manage their own gateways and network infrastructure. However, scaling this model across multiple regions dramatically increases maintenance costs and complexity.
IoT SIM:
IoT SIM solutions once had higher monthly costs per device, but global multi-network providers like Zhongyi IoT now offer flexible pay-as-you-go and pooled data plans, reducing operational costs dramatically. There’s no need to build or maintain infrastructure — the SIM card works anywhere within carrier coverage.
NB-IoT:
NB-IoT requires operator partnerships and certified modules, which can limit flexibility. Costs vary by region depending on carrier pricing structures.
Verdict:
For massive, distributed deployments, IoT SIM cards deliver the best balance between cost, scalability, and simplicity — particularly when working with global providers that handle multi-network roaming.
5. Integration and API Connectivity
A key differentiator for modern IoT connectivity is the ability to integrate directly with enterprise systems.
Zhongyi IoT, for instance, offers a self-developed platform with API integration, allowing gas companies to monitor SIM status, data usage, device connectivity, and alerts directly within their existing management systems. This eliminates manual tracking and accelerates fault detection.
LoRaWAN solutions, while flexible, often require middleware or third-party integration layers to connect to billing or monitoring systems.
NB-IoT depends heavily on operator APIs, which can be inconsistent across countries.
Verdict:
If your utility already uses smart metering management software, IoT SIM platforms like Zhongyi’s enable smoother API-to-API connectivity and seamless data flow.
6. Security and Data Protection
Security is non-negotiable for gas companies handling customer and consumption data.
IoT SIM:
Cellular IoT operates over licensed spectrum and benefits from built-in encryption, SIM authentication, and VPN tunneling. Providers like Zhongyi IoT also offer private APN/VPN services to ensure data isolation between the gas utility and public networks.
LoRaWAN:
LoRaWAN supports AES-128 encryption but is still susceptible to packet replay or interception in poorly configured networks. Security depends on gateway management and end-device authentication.
NB-IoT:
NB-IoT inherits cellular-grade security, comparable to IoT SIM, though operators must support end-to-end encryption.
Verdict:
IoT SIM and NB-IoT lead in enterprise-grade data security, while LoRaWAN requires careful configuration to match that standard.
7. Maintenance and Lifecycle Management
IoT SIM:
Modern IoT SIMs can be remotely managed — activated, deactivated, or switched between networks via cloud dashboards. Zhongyi IoT’s management portal, for example, allows real-time SIM monitoring and automated alerts for abnormal usage.
LoRaWAN:
LoRaWAN networks demand manual maintenance of gateways, which can become a burden for utilities managing thousands of meters.
NB-IoT:
Maintenance is simpler since devices connect directly to carrier infrastructure, but remote SIM control is limited compared to full IoT SIM platforms.
Verdict:
For global visibility and long-term manageability, IoT SIM platforms with remote controls are the superior choice.
