Refurbishment is the way to go! Sure, you can get the newest phone on the market, but most Android and Apple smartphones have a 6-8 year lifespan (until they can no longer be upgraded via software updates). Refurbs are a "green" way of upgrading without absorbing a huge cost. I love the iPhone 12 I purchased through Back Market. I chose a "very good" condition phone and received the device with a perfect front screen, perfect camera lenses and only slight marring/scratches on the metal body (chances are, you're gonna put it in a case anyway). So, while minor cosmetic issues don't bother me, my concern was if it would work with my service with no problems... and it did. Charged it up, swapped the SIM card in, and voila, the Unlocked phone worked with my T-Mobile service and immediately showed up on my T-Mobile page as an active device, it pulled my info and apps from iCloud and worked great. I kept my service cost low and the device is now paid for in full and will be with me for a few years before swapping it for a newer model down the line. I love the iPhone 12 and it works perfectly with no issues whatsoever and even the battery seems fine at 86% and that's just fine for the next ...

I was nervous to buy a refurbished iPhone anywhere other than through Apple but the iPhone 13 mini was never available at the Apple Refurbished store, so after looking around I felt the most confident purchasing through Back Market. The 13 mini I purchased arrived a couple of days early and I received notifications when it was going to be delivered so I'd be there to sign for it and the driver did require a signature. The phone was exactly what I'd hoped for and now I feel a little silly being so worried about it. I will buy from Back Market again.

I recently purchased the Motorola One 5G Ace 64GB in Volcanic Gray from backmarket.com, and I couldn't be happier with my decision. This phone is an absolute gem, offering top-notch features at an incredibly affordable price point. First and foremost, the performance of this device is outstanding. Whether I'm streaming videos, playing games, or multitasking between apps, the Motorola One 5G Ace handles everything with ease. The 64GB of storage provides ample space for all my photos, videos, and apps, ensuring that I never have to worry about running out of space. One of the standout features of this phone is its 5G connectivity, which allows for lightning-fast download and streaming speeds. It's amazing to experience such high-speed internet on a device at this price range. I also love the design of the Motorola One 5G Ace. The Volcanic Gray color is sleek and sophisticated, and the build quality feels premium in hand. The large, vibrant display is perfect for watching movies or browsing the web, and the battery life is impressive, easily lasting me through a full day of heavy usage. What truly sets this phone apart, however, is the concept of purchasing a refurbished device. N ...

Great phone with no complaints so far. . My wife cracked her screen on her iPhone 11 and the cost to repair it properly through Apple was the same price as trading it in and buying this refurbished iPhone 12.

I am really happy with my phone (OnePlus 10 Pro) and my experience using Back Market. My phone was shipped quickly and arrived within a week of ordering it. I can't tell it is even refurbished or that it is not new. It looks new and operates lightning fast. It was packaged professionally and has had not a single issue so far (it's been a few weeks). Thanks for everything!

What's the best place to get a GSM unlocked phone?

We believe that Back Market is the best place to get an unlocked GSM phone because our phones are much cheaper than newer editions, yet still have the same quality that you can expect out of the box.

What does it mean if a phone is unlocked for GSM networks?

It's actually pretty simple, since T-Mobile and AT&T use GSM technology to transmit their cell signals, phones that are able to work with both of these carriers are often called GSM unlocked phones. It's also important to mention that GSM unlocked phones are likely to work on foreign carriers, since most international cell providers also use GSM technology to transmit their cell frequencies.

The Best Deals on Unlocked GSM Phones

We don't mean to brag, but we feel we have some of the best deals on unlocked GSM cell phones. Why do we feel this way? Because our phones have been refurbished, they are just a hair more expensive than regular used phones, but come with the same quality as new devices. Pretty cool, huh?
