| Kilmac | Construction: civil engineering and groundworks | Dundee, with several offices and sites | Business mobiles and SIM management on plan.com | 7+ years, 155+ connections |
Kilmac is a civil engineering and groundworks contractor based in Dundee, with more than 180 staff working across several offices and sites. Its mobile costs kept rising because of data overage charges it couldn't see until the bill arrived. Indigo moved Kilmac's 155+ connections onto plan.com's shared data plan, with weekly usage updates from our mobile team. Kilmac now says it has "a consistent, predictable plan with no surprises."
The challenge
Construction teams use a lot of mobile data: drawings, photos, site apps and hotspots for laptops in site cabins. With every connection on its own allowance, a few heavy users could push Kilmac into overage charges each month. Because there was no live view of usage, those charges only showed up when the monthly bill landed.
"With our last mobile provider, costs were rising and surprise fees came out of the blue," Kilmac told plan.com.
What we did
- Shared data across the business: Kilmac's connections draw from one shared pool on plan.com, so a heavy month for one person no longer means overage charges.
- Usage you can see: Kilmac can check its usage at any time in plan.com's my.plan platform.
- Weekly usage updates: our mobile team checks usage every week and tells Kilmac where it stands, so it never goes over its allowance.
- Mobile and SIM management: Indigo looks after Kilmac's connections and SIMs day to day.
- Help out of hours: including last-minute international bolt-ons when someone has to travel at short notice.
Results
- Predictable monthly costs, with no surprise fees
- 155+ connections managed for a business of more than 180 staff
- A plan.com customer for more than seven years
- Weekly usage updates that help Kilmac make better decisions about its mobiles
"Now we have a consistent, predictable plan with no surprises."
