I love my new phone, it really does feel brand new. Being able to go sim only will halve my phone bill. The whole process was very easy, have recommended Back Market to several people already. No more massive bills, delighted

Paid for a premium refurbished unlocked phone. When the phone came it was locked to another network. I had to return the phone leaving me with no phone for some days. I was not impressed. Will not use this site again.
