    • Perfect
Color: Black
This phone is outrageously good for 20$. Works with Mint mobile, which uses the T-mobile network; be careful here as I believe because some providers like AT&T dropped 2G phones, of which this is one. The phone is indeed unlocked, though I've heard that it helps to use whatever SIM card you have in a normal 4G/5G phone first for a bit then putting it in this. This usually bypasses phone networks' restrictions on 2G phones. Also to avoid the mistake I made, I believe this phone uses a micro or something sized SIM; if you use a nano SIM which is what's available on most modern phone it wiggles a little in the slot. It still works, but consider getting an adapter for the SIM. I just wrote way too much about this being a 2G phone, but really, this phone is awesome. It calls, texts, plays music fantastically (with a SD card), with easy-to-use and thoughtful UI (of course no fancy apps or app store). The screen is not large, but it is enough for everything you would do here. The phone is basically unbreakable; if anything the back case and battery might pop out but it wouldn't stop working. ... show more

Color: Coral
It doesn’t work. Had phone on charger 24 hours as instructed and it still didn’t fully charge. Case flimsy and cheap. Inserted SIM card kept receiving message saying install SIM card. Instructions were useless, all it tells you is charge phone and install SIM card

Perfect for what I needed it for! For some reason (that makes no sense to my brother haha), I wanted to keep my old South FL home phone number. It originally went from a Landline, to Vonage, then to Ooma for 20 years. I switched to the free plan for Ooma (only playing taxes which came out to like $5+ a month). I then decided to take the journey to port it from Ooma to Google Voice. After about 16 days it finally ported over to Ting! Which led me to this phone. I cam looking on Amazon for a cheap unlocked GSM phone to use with Ting. This fit the bill. Decided to take a shot and it did what I needed. Took a little while with some searching on Amazon to figure out the thing cause the directions are pretty worthless. Used a nail clipper (I have no fingernails haha) to pry it open. To do that on the bottom right (as in my 2nd pic) just pry in the groove there and it'll come apart eventually. You'll prob have to work around it to get it all off. Then after figuring the right position for the sim card (last pic) got that going. I first tried the top part thinking that's where it goes, but it has to go all the way down. It works with Ting just fine! They got great customer service by the way. This was the cheapest way for me to port the number. I took a picture of the way the battery goes. It only goes in one way. I saw another question about using the flashlight, to do that you can access it from the menu or long pressing the 0 button that has the icon. To turn it on you long press the Phone icon on the right with the slash through it (and very little power icon I just noticed). Volume sounds really loud. Can't comment on battery since I've only taken one call so far to verify my number with Google Voice. This phone screams perfect for kids to stay in touch with their parents. I think I'll keep it as a backup phone and one to travel with (if that ever starts happening again) abroad. Overall outside of the lackluster instructions, it seems like a great phone for what it is. ... show more

    • Very inexpensive waste of time
Color: Black
No carrier works with this phone. Phone refuses to make or receive calls. Just a brief text message is given to coax into people a plan.

    • Cool little phone
Color: Green
It’s a cool little basic phone. But, with a tmobile SIM card this phone has almost no connectivity anywhere my iPhone has it on the same network.

    • small sized, good quality, battery life and features at the price
Color: Black
I bought this phone as an additional one as I wanted to keep my international number active to receive OTP, and it works great for the purpose. It can read sim from other country and work with local network. Phone came with some default language I dont understand but it was easy to switch to English. By going to Phone setting(based on image-spanner and bolts and option 2 from there) This would be challenging for most as default language is not english for this phone. Writing this review on 3rd day of use, still battery lasts and showing more but I am not using it for phone calls/just SMS. It has VGA camera, dual sim, external memory card slots(none of them i used yet). Phone is must buy for the price and if looking for calling/SMS purpose at this time. ... show more
