For many SMB retail stores, a single internet outage is all it takes to shut down checkout lanes, freeze POS systems, and leave customers standing at the counter with no way to pay. When that happens, sales are lost immediately, staff are stuck improvising, and customer trust takes a hit.

Internet outages don’t need to be catastrophic to be costly. Even short disruptions during peak hours can create long lines, abandoned purchases, and frustrated shoppers who may not return. That’s why always-on checkout is a necessity.

The Hidden Risk of Single-Connection Checkout

Most retail stores rely on one wired internet connection to run POS systems, payment terminals, and inventory tools. When that connection goes down — whether due to a local ISP outage, construction damage, or network congestion — checkout goes offline with it.

The result is immediate:

• POS systems lose connectivity
• Credit card payments stop processing
• Buy-online-pickup-in-store workflows break
• Staff revert to manual processes or stop sales altogether

For SMB retailers operating with limited staff and thin margins, there’s often no backup plan — just downtime and lost revenue.

Always-On Checkout Starts with Failover

Failover is designed to solve this exact problem.

A failover solution provides an automatic backup internet connection that activates the moment your primary connection fails. Instead of checkout shutting down, traffic seamlessly switches to a secondary network — keeping POS systems online and transactions moving without interruption:

No manual resets. No waiting on ISP repair timelines. No turning customers away. Failover ensures your checkout stays open even when the unexpected happens.

Powered by T-Mobile’s Nationwide 5G Network

Premier Wireless delivers failover solutions powered by T-Mobile’s nationwide 5G network, separate from your local wired internet provider.

That separation is critical. When a fiber line is cut or a local ISP goes down, cellular 5G connectivity continues to operate independently. T-Mobile’s network covers cities, suburbs, and rural areas across the U.S., providing high-speed, low-latency connectivity designed to support real-time transactions.

For retail stores, that means:

• Reliable backup connectivity during outages
• Faster recovery without manual intervention
• Continued payment processing even when local infrastructure fails

Failover works quietly in the background, activating only when needed, but delivering immediate protection when it matters most.

Preparing for the Outage You Can’t Predict

Internet outages aren’t always announced, and they rarely happen at convenient times. Whether it’s a brief disruption or an extended service interruption, the impact on checkout is immediate — unless you’re prepared.

Failover provides peace of mind by ensuring your store can continue processing payments, serving customers, and closing sales even when connectivity fails. Failover powered by T-Mobile’s nationwide 5G network keeps checkout lanes open, POS systems online, and revenue flowing during internet outages.

If you’re ready to prepare for the outage you can’t predict, Premier Wireless can help. As a T-Mobile Pinnacle Partner, we work closely with T-Mobile to deliver failover solutions powered by their nationwide 5G network.
