Review: Perfect - 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.
Review: Very inexpensive waste of time - 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.

**Q: Do any networks work with this phone? i have had no luck so far! thank you!**
A: Yes, Tello might work. But you have to activate the Tello SIM in a 4g LTE phone, leave it in there, make and receive some calls, and then (and only then) migrate it into the Blu Quad band. That worked for me, hopefully it works for you!

### ⭐⭐⭐⭐⭐ Perfect for what I needed it for!
*by Z***. on September 9, 2020*

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.
