The Challenge
As On Call Security expanded its customer base, the reliability of connectivity within its alarm panels and smart watches became increasingly critical. However, the company was experiencing recurring problems with its existing SIM provider. These issues affected device performance and created additional pressure on the technical and engineering teams.
Beyond the technical shortcomings, the level of customer service from the previous provider fell short of expectations. The combination of unreliable connectivity and poor support began to impact operational efficiency and the company’s high standards to deliver the dependable protection customers expect from a monitored security service.
A recommendation from another trusted business, combined with ongoing frustration, prompted On Call to seek a new, more reliable partner.
The Solution
On Call Security carried out an internal review of their existing setup before going out to market for a new provider. The business was clear on what it needed:
- Highly reliable SIM connectivity for alarm systems and smart watches
- Strong customer service and responsive support
- Competitive pricing
- Compatibility with its existing security solutions
- A knowledgeable provider backed by major network partnerships
Chess met all these criteria.
The onboarding experience was described as “very simple”. The IoT SIMs integrated seamlessly into On Call’s equipment, and the technical team encountered no compatibility issues during setup. Chess provided knowledgeable, helpful support throughout the process, ensuring rapid deployment with minimal disruption.
“Extremely happy with Chess, the have been brilliant from the start, and work really hard to get everything set up with very short notice. Looking forward to working with them going forward. We highly recommend Chess.”
