Real specs, real testing, real verdict — no marketing fluff
In this Cubot X100 review, I’ll break down whether the $179 price tag actually holds up. Bought it off AliExpress just to see if the specs were real. A 120Hz screen and sixteen gigs of RAM on a phone this cheap sounded crazy.
In the hand, it is heavy—thick glass back, big camera bump, feels more like a mini tablet than a normal pocket phone.
Everyone keeps asking me the same thing — does it even work on T-Mobile, or is it gonna drop signal every five minutes. Popped the SIM in, walked to the living room, and it grabbed 5G, two bars, no issues. Basement though? Speed tanked. Not surprised honestly, my main phone does that too in there.
The screen is surprisingly smooth scrolling through feeds, but the 64MP camera falls apart completely in low light. For under two hundred bucks, it makes a solid backup phone as long as you don’t expect Samsung quality.




💡 Bottom Line: Is It Worth Your Cash?
- Grab this if you use T-Mobile or AT&T and need 256 gigabytes of room without crossing the $180 mark.
- It earns a solid 8.5/10 from us for daily reliability.
- Expect to pay about $179, though coupon drops happen constantly.
- The main reason people buy this is because finding so much memory at this price is basically unheard of.
- Just a heads up: Verizon users should skip it.

⚡ What’s Actually Under the Hood?

| ⚙️ Internal Chip | Octa-Core MediaTek Dimensity 7025 |

⏱️ How Fast Is It Really?
Benchmark apps give this chip a score around 420K. What that actually means for you is that scrolling through Instagram, watching YouTube, and opening apps won’t stutter. Plus, everyday users say the big battery easily survives 8+ hours of screen time, meaning it won’t die on you before dinner.
⚠️ Network Check: Will It Get Signal?
What you need to know:
- Mint, Metro, and T-Mobile: Expect totally fine 4G and 5G reception.
- AT&T & Cricket: Hooks up perfectly for calls and LTE data.
- Verizon & Visible: Do not buy this. Verizon blocks these kinds of unlocked global phones.
- Global Travel: Works great on almost any standard GSM network in Europe or the UK.
📸 That Weird Little Screen on the Back
The main 64MP lens takes surprisingly good photos outside in the sun. But the most unique trick here is the little secondary screen near the cameras. It lets you skip Spotify tracks, read text messages, or frame up a selfie using the high-quality back camera without ever flipping the phone over.

❓ Common Questions People Ask
Can I use this on US carriers?
Yes, but mostly GSM ones. It hooks up perfectly to T-Mobile, Mint, and AT&T. Just stay away if you are on Verizon.
What is the point of the second screen on the back?
It’s basically a mini smartwatch built into the back of your phone. You can tap it to skip songs, read notifications, or use it as a mirror to take selfies with the main camera.
Do you actually get 16GB of physical RAM?
Not exactly. The phone has 8GB of real physical hardware RAM, and Android uses some of your storage space to create another 8GB of “virtual” RAM to help keep background apps open.
Does the battery actually last all day?
Easily. The 5100mAh battery usually gives people around a day and a half of normal use. When it dies, the 33W charger fills it up halfway in about 25 minutes.
