Looking at the webpage, it's obviously a 100% Chinese product licensing the Trump name.
There are numerous errors on the page, from a processor section that doesn’t list a processor, RAM that’s described as storage, and the boast of a “5000mAh long life camera,” when it presumably means the battery.
If you ever thought the Trumps weren't grifters, this should clear it up:
“Trump Mobile is going to revolutionize cellphones, mobile calling,” Eric Trump told Fox News
There's absolutely nothing revolutionary here. It's a cheap Chinese phone in a tacky case and an overpriced very-not-new MVNO phone service.
