What to do when the signal drops at an event

The short answer

Keep cash for the first minutes, move to a second connection if you carry one, and ask customers to pay by another method. Before the event, plan for a drop by carrying a float, a charged backup device and a note of your provider's support number.

Why signal fails at events

Large crowds put heavy demand on mobile networks, and temporary sites in fields or car parks can have thin coverage. Weather and distance from the nearest mast also play a part. Expect a slow connection at the busiest moments.

Prepare before you go

  • Ask the organiser about coverage and whether the event provides wifi for traders.
  • Carry a float so you can take cash.
  • Charge every device and carry a power bank.
  • Save your provider's support number on your phone.
  • Print a QR code for your signage as a second route.
  • Float counted and in the cash box.
  • Backup phone or second connection charged.
  • Printed QR code on the stall sign.
  • Provider support number saved.
  • Pen and paper to log sales made during an outage.

Log any sale you take during an outage and enter it in your records when you are back online, so your accounts match your takings.

When it drops

  1. Tell the customer calmly and offer to take cash.
  2. Check your own device is connected, then try switching between wifi and mobile data.
  3. Move your phone to a spot with better signal if you use a Bluetooth reader, keeping the reader within range.
  4. Use your second connection or backup device if you have one.
  5. Keep a short list of waiting customers rather than losing them.

Offline modes

Some readers can store a payment and send it later. Rules and limits differ by provider, and an offline payment can fail when it is eventually sent, so check your provider's terms before you use this option. Ask your provider how it handles declined offline payments.

Keep customers on side

Put up a small sign explaining the options, such as cash, a QR code or return later. Customers are usually patient when you are open about the problem. Offer to hold an item for a short time while they find cash.

Learn from each event

Note where and when the signal dropped, and tell other traders and the organiser. Use this when you decide which events to rebook. The card reader or QR payment guide shows how to choose a mix of methods.

Common questions

Frequently asked questions

Can I take card payments without signal?

Some readers allow offline payments that send later, and the rules depend on the provider. Check your provider's terms, and carry cash as a backup.

Should I carry a second mobile connection?

Many traders carry a second connection, such as a second phone on a different network, so they have another route if one fails.

Will the organiser provide wifi?

Some do, many do not. Ask before you book and check the trader pack.

What if a customer cannot pay?

Offer another method, hold the item for a short time or take their contact details. A friendly approach often keeps the sale.

Marquees for larger events

Race meetings and large shows often call for more cover than a single gazebo. Gala Tent makes modular marquees for festivals and events.
