Will a payment in progress go through?

A transaction that is mid-approval at the exact second the line drops may need to be run again. Everything after that goes through on cellular.

Do the delivery apps need anything special?

No. Their tablets just need internet, and they get it from the backup the same way they get it from your main line.

Can we keep using offline mode as well?

You can, but with backup internet you should rarely need it. Most restaurants keep it as a last resort.

Backup internet for restaurants

From the FAILOVER5 team at Twisted VoIP, Chandler, Arizona · Updated October 2026

It's 7:15 on a Friday. The dining room is full, there are six tickets on the rail, and the card reader at table 12 spins and times out. The delivery tablets have stopped chiming. Nobody in the kitchen knows yet, but the internet is down.

Cloud point of sale made restaurants faster. It also made them dependent on one cable coming into the building.

Offline mode is a gamble

Toast, Square and Clover can all store card payments while offline and send them later. Those payments are not approved at the table. If a card is declined when the system reconnects, the meal is already eaten and the money is gone. Most processors also cap how much you can take offline, and some cards can't be taken offline at all.

Offline mode also does nothing for DoorDash, Uber Eats or Grubhub. Those orders simply stop arriving, and a restaurant that stays unreachable long enough gets paused by the apps.

What to put on the backup line

POS terminals and handhelds
Kitchen display screens and ticket printers
Delivery tablets
Phones, if they run over the internet, so takeout calls still come in

Leave guest WiFi and any music or TV streaming on your main line only. That keeps your backup data for the things that make money.

Where the router goes

Walk-in coolers, steel prep tables and hood systems all block cellular signal. Mount the router up high near the front of house, close to a window if you can, and run its WiFi or a cable back to the kitchen network.

Suggested plan: 20 GB plan, $123/month

Card payments and order traffic are tiny, but kitchens add up: several terminals, screens, tablets and phones. 20 GB covers a busy night with room to spare.
