    • Another fine Samsung phone
Color: Phantom Green Size: 256GB
I've been using Samsung phones since the Note 4, and I have no regrets. This latest model is pricey, yes, but the battery lasts a long time, the screen is sharp, and the camera takes great pictures.

    • SAMSUNG GALAXY 23 ULTRA
Color: Phantom Green Size: 256GB
Love this phone, currently using it for this review. Wonderful camera for capturing memories. This stylus is just a great touch for typing, or if even using it on mobile games. Been so happy with this phone and the purchase was so worth it. Having a dual sim system has really helped since I went traveling overseas. It was very easy to have an extra slot for the sim card. Have nothing but great things to say about this phone ... show more

    • I'm Finally Current & Beyond
I use my phone for Work & Pleasure. I Love Living the Glory Days at Rock Concerts and I Finally have the BEST Camera on the Planet, for the Whole Last Year. I Can't wait til Next week to try it out. 200mp Camera, 8K Video. I also got mine with 512gb of Storage and 12gb of RAM. This One is a Global Model and handles Everything: 2G, 3G, 4G and 5G. I don't even hook up to the Company WiFi + I'm in a building that has Tons of Steel for Interferance and a Computer/IT Room that's almost as Big as my garage & they run on Verizon. The past week, I do Everything from my desk, whether I'm using the phone, adding emojis to a text, sending Pictures or sending emails; It ALWAYS WORKS, even if I forget to turn on Regular WiFi, Not Company WiFi. No more walking 75 feet to the window to try and get a Signal. No more Walking out to the Parking Lot to try and get a Signal. Ya gotta do your Homework and Granted, Everyone Wants a Deal, but sometimes If you Want the Best, you gotta Pay for it and It's Actually Worth it. I made sure that I had this thing as Loaded as I could afford & I am fully Satisfied. 😎👍🏻 ... show more

    • No wifi calling option on the "global" S23 Ultra.
Color: Phantom Green Size: 256GB
I live in a rural area that does not have cell service. Further, it is literally impossible to get a landline from AT&T as they discontinued service to new customers several years ago. The only people who have POTS with AT&T are those who were grand fathered in. My point is that, without wifi calling, I have no means of communication with the outside world. I have gone to the neighbors to use their landline four times to call my service provider. Still no option for on the phone for wifi calling. 30 days have passed and I am out a lot of money, have a phone that is useless to me, and can only communicate with others by email or social media. I knew I shouldn't buy a phone off Amazon, but alas, I did it anyway. Lesson learned. P.S. A couple of reviews mentioned the seal was broken on the box upon arrival, mine was as well. Makes me wonder if this is a legit seller. ... show more

Color: Phantom Green Size: 256GB
Good device. Not sure i like it better than my Motorola edge 2021. Replaced due to busted screen. Motorola had better Fingerprint reader and could just shake to turn on flashlight. Time will tell. I'm starting to get use to it now. Works well. Best thing is the GREAT pictures. That one item alone makes phone worth it. ... show more

    • Rooted and working on T-Mobile. Inaccurate description!
Baseband version: S918BXXU3BWJM (Monaco version) This SM-918B/DS works with T-Mobile. I have no issues with 5G. There is only one 5G band this phone doesn't support but my older galaxy phone never used that band anyways. I successfully unlocked the bootloader and rooted this device. So worth it! Use Magisk and ODIN. Check FDA forums. Seller: TechnoMaster, sent a 20 watt cheap wireless charger with an old style micro usb. Garbage.. The description on this post had multiple errors. The model/baseband version was incorrect. Also, this phone wont work with any carrier. Do your research carefully. Look out for sellers out of Florida... They are all the same.. And bad.. ... show more
