I'm selling a galaxy z fold 4 I'm going to tell you an amazing trick I've been using technically the esn is bad but somehow I've still been able to activate it on certain networks not all of them but some if you buy the phone here's how to get it activated see you can only do it via ESIM which is basically like a virtual Sim that's the only way you can activate it so when your signing up for a service with esim and they ask you the imei number the number you give them is the esim imei located in settings after that you just continue setting up via esim I've been able to activate this phone with visible wireless and us mobile so far I'm sure it'll work with other ones if you have any questions about it feel free to ask phone has minor scratches barely noticeable and on the unfolded screen there is a weird white line I'm not sure how to get it removed
