A Bigger Name Doesn't Always Mean a Better Refurbished Phone
giffgaff is one of the UK's best-known mobile brands. That familiarity can make it feel like the obvious safe choice.
But when you're buying a refurbished phone, the things that affect your day-to-day experience are not the size of the logo.
They're things like:
-
Will the battery comfortably get me through the day?
-
Has everything actually been checked properly?
-
What happens if the phone isn't quite right?
-
Can I speak to somebody if something goes wrong?
So, why choose The Big Phone Store?
You Spend Less Time Looking for a Charger.
giffgaff guarantees at least 80% battery health.
The Big Phone Store guarantees 85%+.
Five percentage points might not sound exciting on a comparison table. It becomes much more important when you're halfway through a workday, travelling home, using Maps, ordering an Uber or waiting for an important call.
Your phone should fit around your day. You shouldn't have to plan your day around your charger.
And if you want even more reassurance, eligible TBPS phones can be ordered with a new battery upgrade.
We do more checks, so it doesn't become your problem
We carry out a 90-point testing process.
You probably don't want to spend your first night with a new phone testing the microphone, cameras, charging port, speakers, buttons and connectivity yourself.
You want to move your photos across, log into your apps and start using it.
That's the point of the extra testing.
We try to find the problems before you ever have to.
If Something Goes Wrong, You Can Actually Speak to Us
Most people do not think much about customer service when everything is working, but it becomes very important when it isn't.
Maybe your delivery hasn't arrived. Maybe you're unsure about the condition. Maybe you need help with a return or warranty claim.
giffgaff doesn't operate a traditional call centre, and relies largely on their community to help customers, instead of the people behind the operation.
With The Big Phone Store, you can call our UK team, message us on WhatsApp or visit us in Wolverhampton.
Sometimes you don't want another chatbot, help article or support ticket. You just want someone to sort it.
45 Days to Make Sure You Actually Like It
Buying a phone online is difficult because you cannot properly judge it until it is in your hand.
Maybe the Pro Max is much bigger than you expected, maybe you're switching from Android to iPhone and hate it, maybe you bought it for your child and they need something smaller... Or maybe you simply change your mind.
giffgaff currently gives you 21 days to change your mind.
The Big Phone Store gives you 45 days.
That's more time to make sure the phone works for your life, rather than rushing to decide whether you should keep it.

The Verdict
Smarter Savings at The Big Phone Store
Your phone probably isn't the most exciting part of your day, but when it stops working properly, it can ruin it.
It's your alarm in the morning. Your train ticket. Your sat nav. Your camera. Your bank.
That's why you should choose a refurbished phone that's built to last, with live customer support you can count on.
