The client is a regional banking institution with 45 branch locations spread across urban and rural areas. Its branches and ATM network rely on connectivity for customer transactions, loan processing and ATM operations, and the bank had historically run these services over traditional wired connections. The case study does not name the institution.

The bank relied on traditional wired connections for critical operations such as customer transactions, loan processing and its ATM network. Those connections failed more often than the business could tolerate. Fiber cuts, weather disruptions and network congestion caused frequent outages, and each one meant downtime at a branch or ATM.

The impact was felt on two fronts. Customers experienced failed transactions and unavailable services, which damaged their experience of the bank. Internally, every outage required manual intervention from IT, hurting operational efficiency.

The institution needed a reliable failover solution that would guarantee 24/7 connectivity across all 45 branches without depending on a single carrier or a single piece of infrastructure. It also wanted an approach that would scale as the bank opened new locations.

Infinite Wireless deployed 4G vSIM-enabled routers at the bank's branches and ATM locations, providing automatic failover to the strongest available network.

Unlike traditional failover options tied to a single carrier SIM or eSIM, Infinite Wireless' multi-carrier vSIM technology can dynamically connect to and switch between more than 40 LTE carriers nationwide. This removes the downtime risk that comes with relying on one network.

The implementation had four components. Multi-carrier failover gives instant switching to the best available network so transactions continue uninterrupted. A dual-radio module uses one radio for bootstrapping and the other for the active carrier connection, which keeps transitions seamless. Plug-and-play deployment meant devices were installed at each branch and ATM location without on-site technical expertise. Centralised management through Infinite Wireless' cloud-based platform gave the IT team real-time visibility and control over every location.

Together these removed the single points of failure in the bank's wired-only setup and gave it the flexibility to expand into new locations without connectivity concerns.

• 99.999% uptime with no downtime across all 45 branches
• Transaction failures were prevented, improving customer trust and retention
• Automatic failover eliminated manual intervention and reduced IT workload
• Uninterrupted transactions and ATM uptime across the branch network
• The bank can expand to new locations without connectivity being a bottleneck
