Sony Xperia 1 IV 256GB - Black - Unlocked

I checked out the site and after some thought I decided to give it a go. The whole experience was great and very straight forward. I was kept informed at all times and was surprised at the quick delivery. The price is crazy good and there's hardly a mark on the phone. It works perfectly. My only gripe would be how long it took to upload all of the updates, but this could be in part due to my Internet speed. That aside I'm very pleased with my purchase.

Item exceeded expectations and I was very pleased with how quickly it was dispatched, especially as it was during the Christmas rush. Have since recommended Back Market to a friend who has purchased her own phone from you.

My son suggested I buy a phone from Back Market and stick to my SIM only contract, rather than pay the exorbitant monthly fees. My old Sony suddenly wouldn't make/receive calls once my network provider switched to 4/5G. I was a little dubious of what sort of phone I would get, but was hugely and pleasantly surprised. Got a half price modern Sony phone of my choosing, and I really couldn't tell it was used. I didn't even go for the excellent quality merely the Staff Pick! Choice of phones were great. Came through the post quickly and easily. Back making calls. Would definitely recommend. Great service. Thanks.

Excellent ! Although I ( 1962 ) am a friend of " old school communication " ( = talking to people ) everything really fitted, pleasant ( and not too ) cool tone on the website, but underpinned with very serious information. Time was kept. Product is practically like new . . . and the Sony XPERIA 1 IV really is a "Mercedes Benz". ( what I want to say: as I'm really NOT a "fast" person - I still haven't swapped the SIM card from the old to the new phone ) I can't say anything about the phone function etc., but I assume that it works just as well as the rest of the phone ) i.e.: when I'm "on the money" again: I will gladly buy from you again iLG NIki Bandian

The device arrived in perfect condition, with a cardboard box as packaging, which I was able to reuse for the return. TopOne GmbH sells the SOG06, a Japanese model that is incompatible with European 5G frequencies and VoWifi. So I didn't keep it. Back Market's after-sales service was very efficient and understanding, and the returns process went without a hitch.

⚠️ JAPANESE MODEL ⚠️ 5G and Vowifi not available, EDGE network only (2g!!) in 2025 is not possible... Better communication is needed in the product description and the model should be clearly indicated (SOG06), which is not compatible with our European networks. It's a shame, because the sound wasn't as limited as our European models! In terms of sales and after-sales service, there's nothing to criticise about Back Market, it's straightforward 👍

I have doubts about the battery and the volume of the ringtone -The battery can sometimes run out suddenly. I'm not sure yet whether it's the battery or the intensity with which I use the phone at certain times. -The ringtone goes loud first and soft right after. As a result, I sometimes miss a call. I haven't yet found a setting that affects this.
