    • Great value for money
Color: purple
I’m genuinely impressed with this unlocked 3G mobile phone. The 6.6-inch screen is bright and spacious, making videos, browsing, and everyday use super comfortable. For the price, the performance is solid. Android 10.0 runs smoothly for calls, messaging, social apps, and light multitasking. The 16GB ROM with support for up to 128GB SD card is a big plus—you can easily expand storage for photos, videos, and apps without worry. I love the dual SIM feature, which is perfect for separating work and personal lines. The dual cameras do a good job capturing clear photos for everyday moments, and the Face ID works reliably and adds extra convenience and security. Overall, this phone offers excellent value for money. ... show more

    • Nope
Color: blue
Unable to connect a SIM card because it shows as an iPhone on the carriers end but it’s an Android and they’re just saying they can’t do anything with a cloned phone.

The phone is promoted as being capatable with Metro PCS and T-Mobile sim cards but is not. The phone is also not unlocked. Be careful buying this phone.
