GSM SIM card for cellular communication

GSM SIM card for modems, meters and telemetry systems

📡 A GSM SIM card is used to connect compatible equipment to a cellular operator’s network.

It can be installed in GSM/GPRS modems, smart meters, telemetry controllers, alarm systems and remote-monitoring devices.

📊 Meter-data transmission

• gas meters;
• water meters;
• electricity meters;
• GSM/GPRS modems;
• telemetry controllers;
• gas AMR systems;
• electricity AMR systems.

🌐 How it works

1. The SIM card is installed in a compatible modem or meter.
2. It is activated on the operator’s network.
3. APN and server parameters are configured.
4. The modem registers with the cellular network.
5. Readings are transmitted through GPRS, mobile data or SMS.

A SIM card cannot transmit readings by itself. A compatible modem and correctly configured system are required.

📲 Communication options

• GPRS mobile data;
• 2G, 3G or 4G depending on equipment;
• sending and receiving SMS;
• connection to a remote server;
• data transfer to an automated metering system.

🔄 Standard or M2M SIM

A standard SIM card with a suitable tariff may be sufficient for periodic low-volume data transfer.

For industrial equipment, a dedicated M2M or IoT SIM may be preferable when offered by the operator.

📐 SIM-card format

• Mini-SIM;
• Micro-SIM;
• Nano-SIM;
• universal multi-size SIM card.

Check the modem’s SIM-slot size before purchasing.

📡 Cellular coverage

Transmission reliability depends on the operator’s signal at the installation site.

A basement, metal cabinet, underground chamber or remote location may require an external antenna or a different network operator.

💳 Tariff and balance

The SIM card must maintain a positive balance and an active service plan.

• monthly service fee;
• included mobile-data allowance;
• SMS charges;
• number-validity period without top-up;
• availability of an M2M tariff;
• automatic payment options.

⚙️ APN configuration

• APN name;
• username and password;
• SIM-card PIN;
• server address and port;
• data-transfer protocol.
