IoT & M2M SIM cards: connectivity that fits the use case
Machines are not smartphones: KHTC matches IoT and M2M connectivity to the actual use case, multi-network or single-carrier SIMs, pooled data, the right platform to activate, monitor and block cards, and contracts that scale from a pilot batch to thousands of devices. Provider-neutral, free of charge for you.
Typical problems we encounter
- consumer SIMs in machines, until the first outage
- hundreds of cards, no overview which is active where
- one device runs riot and burns the data budget
- projects stall between pilot and rollout pricing
- roaming devices lose the network abroad
What KHTC delivers
- Use-case analysis: data profile, regions, criticality, before any tariff talk.
- SIM & network strategy: multi-network, single-carrier or fixed-IP, chosen for coverage and failure behaviour.
- Management platform: activate, monitor, throttle and block cards yourself, with alerts before budgets burn.
- Scaling contracts: pilot conditions that survive the rollout, no renegotiation cliff at card 101.
- Lifecycle support: swaps and replacements across the whole estate, ongoing invoice checks available as a bookable add-on.
How it works
- 1 · Understand: We review your contracts, invoices and requirements, across every provider, with no obligation.
- 2 · Compare: You get a written comparison of what the market offers for your situation, including “keep what you have” when that wins.
- 3 · Implement: We negotiate, order, port and migrate, coordinated so your operations never stand still.
- 4 · Support: One dedicated contact for incidents, changes and renewals, for the whole contract term, not just until signature. Ongoing invoice auditing is available as a bookable add-on.
Who this is for
- machine and equipment builders
- telematics and fleet operators
- energy, metering and smart-building projects
- any product that phones home
Multi-network SIMs: when they are worth it
A SIM that roams across all German networks buys resilience, at a price. For stationary devices in well-covered areas a single-carrier card is often cheaper and just as reliable; for vehicles and critical sensors multi-network wins. We calculate the trade-off per use case instead of selling one answer.
From the field
The most expensive IoT SIM is the forgotten one: estates typically contain 5–15 % of cards that bill every month and transmit nothing.
FAQ: IoT & M2M
Short answers, happy to go deeper in a personal conversation.
What is the difference between IoT and M2M tariffs and normal ones?
IoT/M2M tariffs are built for small, steady data volumes, long device lifetimes and central management, including features like fixed IPs, network steering and API control that consumer tariffs lack.
Can we manage the cards ourselves?
Yes, that is the point of the platform: activate, deactivate, monitor and set alerts in one portal, with our team as escalation behind it.
Do the SIMs work abroad?
Depending on the tariff, across the EU or worldwide, we match roaming zones to where your devices actually operate.
How do we start without committing to thousands of cards?
With a pilot batch under conditions that already reflect rollout pricing, so scaling later is a purchase order, not a renegotiation.
