Connected farms and field operations
Smart Agriculture SIM Cards
Connect sensors, gateways, machinery and automation across farms where distance, terrain and power make ordinary connectivity difficult.
In brief
Smart-agriculture SIMs provide cellular backhaul for devices measuring soil, weather, water, livestock or machinery. The design may connect each asset directly or aggregate local sensors through a cellular gateway, depending on coverage, energy and economics.
What you can connect
- Soil, weather and crop sensors
- Livestock and equipment tracking
- Greenhouse and irrigation automation
- Farm gateways and remote cameras
Connectivity is only one part of reliability
One farm can contain several distinct radio environments and coverage shadows.
Giving every small sensor a cellular modem may be less efficient than a local LPWAN plus gateway.
Remote automation must degrade safely if telemetry is delayed or connectivity fails.
Technical planning
Design the complete connection
Architecture
Large assets and gateways can use cellular directly; clusters of small sensors may be more efficient over LoRaWAN, Bluetooth or another local radio with cellular backhaul. The farm map should identify terrain, sheds, boundaries, power sources and control points rather than treating the property as one coverage location.
Data and power sizing
Separate fixed sensor readings, livestock or machinery tracking, camera traffic and remote actuation. Include solar and battery energy, seasonal population changes and over-the-air updates. A gateway concentrates data and cost but also becomes a shared failure point, so local buffering and spares matter.
Solution design
What we qualify before recommending a SIM
Coverage maps and headline data allowances are a starting point. A production design needs the device, traffic, locations and operating model.
- Farm map, terrain, buildings and representative locations
- Direct-cellular versus gateway architecture
- Sensor payloads, sampling and battery targets
- Antenna, solar and enclosure design
- Command safety, local control and alert escalation
- Seasonal fleet changes and support access
Multi-provider by design
Choose Onomondo, Telnyx or another fit
Telnyx publishes a dedicated smart-agriculture use case and supports IoT SIM/eSIM plus private network options. Onomondo is also relevant to geographically distributed fleets needing non-steered networks, low-data economics and diagnostics. iSIM selects after a farm-level coverage and architecture review.
Telnyx publishes a smart-agriculture use case and offers API-managed IoT connectivity. Onomondo can suit geographically distributed fleets needing non-steered network choice and deep diagnostics. The provider decision follows a farm-level radio and architecture trial, not a generic rural coverage promise.
Availability note: networks, radio technologies, IP features, regions and platform controls vary by provider, country and plan. We verify the proposed configuration during the pilot.

What the pilot should prove
- Map representative low points, sheds, boundaries and moving assets.
- Compare direct cellular with a local-radio gateway where appropriate.
- Measure solar margin and weak-signal retry behaviour.
- Test safe offline control, alert escalation and gateway replacement.

Frequently asked questions
Does every farm sensor need its own SIM?
No. Direct cellular works for some assets; clusters of small sensors may use LoRaWAN, Bluetooth or another local link to one cellular gateway.
Can IoT SIMs work with solar-powered devices?
Yes, if the modem, network technology, reporting schedule and firmware are designed for the available energy budget.
How do I test rural coverage?
Test the chosen modem and antenna at representative low points, sheds and remote boundaries – not only near the homestead or with a phone.
Can the same service support trackers and fixed sensors?
Potentially, but mobile and stationary devices can need different network technologies, data profiles and power settings. Group policies help separate them.
Can remote commands control pumps or gates?
They can, through compatible hardware and software, but local interlocks, authentication, logging and safe offline behaviour are essential.
