A Little History

ONCALLERS® started in 2007 as an on-site mobile IT and repair group, servicing local Chicago businesses with their technology needs.

Focusing primarily on the on-call services, and with the inception of the first generation iPhone from Apple, ONCALLERS® was at the forefront of any IT company in the Chicagoland area to provide full refurbishment and repair service for this new technological device.

As the industry and demand grew ONCALLERS® opened its first retail location in the northwest side of Chicago, to not only service the commercial and educational clients but also to be a drop off center for the consumer clients needing help with their technology hiccups.

Retail Operation & Volume Repair Centers

Now ONCALLERS® operates 5 retail locations throughout Chicagoland, while franchising new retail quick repair centers throughout all 50 states. We also operate a state of the art wholesale refurbishing depot, providing full IT, refurbishing, repairs and consulting to Fortune 500 companies, school districts throughout the region, local hospitals and small businesses.

ONCALLERS® main goal is to provide an efficient service with a straightforward approach at affordable rates to ALL of our clients.

What makes our clients come back to us, is the perfection and approach to our most important services:

  • FREE Diagnostics
  • FREE Pickup and Delivery (throughout Chicagoland)
  • Fast Turnaround Time (most repairs are done within 24 hrs)
  • No Contracts (no commitments for using our services)
