Plan advice
M2M SIM and connectivity planning for industrial device fleets
We help you choose the right M2M SIM and data plan for your device fleet and size it on data volume and data rate. Independent advice: we do not sell SIMs or airtime.

Connectivity as part of the system
Connectivity planning keeps gateways, sensors and assets online across sites and networks, and keeps data intact during coverage gaps.

FAQ
01Do you sell SIM cards or airtime?
No. We advise on the choice of M2M SIM and data plan and size it on your data volume and data rates. SIMs and airtime come from the carrier or MVNO you select; Melqart supplies the gateways and the integration.
02How do I choose an M2M SIM plan?
An M2M SIM is a cellular SIM provisioned for machine-to-machine data traffic rather than phone use. Choose a multi-network roaming plan where coverage varies, or a single-network plan when there is no hard real-time constraint, and size it on data volume and data rates.
03What is M2M vs IoT?
M2M describes direct device communication; IoT usually adds platforms, data models, device management and application workflows.
04Do I need a multi-network M2M SIM?
It depends on coverage and timing needs. Where coverage varies, multi-network roaming improves availability. Without a hard real-time constraint, a single network can be enough, with gateway buffering covering the gaps.
