Fixed line down? Your POS shouldn't be.

When the Line Goes Down, Your Business Shouldn't: Cellular Backup for Always-On Operations

For multi-site operations, connectivity isn't optional. It's revenue. When a primary fixed line fails, POS systems go dark, payments stop, and every minute costs money. Fiber cuts, local ISP failures and infrastructure outages can hit any site at any time, with no warning, and traditional fixed connectivity has no built-in redundancy to absorb the blow.

Telecom26's Business Continuity solution adds a cellular continuity layer to every site. A router-based fallback detects loss or degradation of the primary connection and switches to mobile networks instantly. There's no IT ticket and no downtime window. When the fixed line recovers, the connection steps back automatically.

Built for resilience, billed like insurance

At the heart of the solution is Telecom26's global multi-IMSI IoT SIM. Each SIM can attach to multiple mobile networks, so a single operator outage never blocks the fallback. It always finds the best available network, drawing on more than 1,100 partner networks worldwide.

Data is pooled across all SIMs in a deployment as a shared annual allowance at competitive pay-as-you-go rates, so you pay for standby protection without wasting capacity. SIMs, the data pool and traffic prioritisation for critical services are all managed from one place on the Telecom26 management portal.

Proven at scale in European retail

A major European retail chain with hundreds of stores turned to Telecom26 to eliminate the revenue risk of connectivity outages. With POS and payment systems critical to daily operations, even a few minutes of downtime meant lost sales and frustrated customers.

The result: 1,500 SIMs deployed across the estate, around 1 GB per SIM per year of pooled EU+ data, fully automatic failover, and a five-year commitment that gives long-term cost certainty as new sites come online. Stores stay fully operational during primary outages, and the chain avoided the cost of installing a redundant fiber circuit at every site.

As the retailer's Head of Network & Telecom Services put it, Telecom26's cellular fallback lets them maintain connectivity across multiple mobile networks and keep POS systems running even during network outages.

Whether you run 10 sites or 10,000, in retail, logistics, healthcare or utilities, Business Continuity scales with your footprint.
