OYYU T7 Pro Android Tablet 7 Inch 4G LTE Phablet 3G, Android 7.0 Dual SIM Card Tablets PC, MTK8735 Quad Core, 1GB RAM 16GB ROM, IPS Display 1280x720,Dual Camera, Wi-Fi GPS Bluetooth OTG Black Rear

Believing that this could take a SIM and perform as a navigational system using Google maps or Waze, I thought this was perfect. Wrong, invalid IMEI number and not one carrier I visited in Houston could support the phablet. Junk.

Originally had a hard time getting device set up with SIM card but finally after assistance from AT&T store, we were all set...Prepaid program works good when I need it and now I have piece of mind that I have a device to travel with. As a android tablet, it works well and I do feel that this size 7" has a lot going for it as a reader, web surfing, email, calling and messaging.

I sent it back it was slow for my needs as for the price it's great if you want your kids to have a tablet.

This tablet works as a phone and tablet. I brought a Speedtalk mobile prepaid SIM on Amazon. It's simple to activate and install. The tablet recognized the SIM right away. Configuration was ultra simple. The SIM runs on the T-Mobile network. And I get 3g, 4g and 4g LTE data on it. Build quality is not the greatest, all plastic. Sound quality is good. Multitasking is ok, it only has 1gb of ram. But for basic use as a phone, texting and data it's great!. It comes with android 7.0 installed. I put a Samsung 32gb micro SD card in and formatted it as internal memory. No slow down accessing storage memory. Overall, I'm very happy with the tablet.

It works for me but the battery goes very fast, by 2pm I have to add an external battery pack. I guess the RAM is not enough either, it's on the slow side. I can say that it does work for me though, by adding some apps to help it do what I need.

This works fairly well for a tablet at this price point. I bought the Oyyu primarily for use while traveling, and will use this for a few week trip to Asia next month, fpr road navigation, booking hotels, local phone calls using a short term pre-paid sim for that country.. (Using the T7 makes so much more sense than my 10 inch tablet with NO phone capabilities, and about twice the bulk of the T7) It's a little hard to access the sim and memory cards without some sort of tool, or a very strong fingernail. Battery life and audio are nothing to brag about, but acceptable. Overall I happy with my purchase.I'm not a high end user of stuff like this. I watch some movies, do normal internet things, and I have used the t7 to pilot a small quadcopter.. I hope somebody comes out with a tempered glass screen protector for the t7? Not seen one yet.

I have tried many low-price tablet and this best tablet for the money. Very responsive, works with 4g (T-mobile in my case), 32 gb SD card.Happy with my purchase

Phone NEVER worked.Slow a.f. with every app. I didn't add any apps to it, but still slow a.f.Camera was of the poorest quality. The flash was almost nonexistent.I bought as a burner when my phone died, and I should have just bought a new phone.Worst purchase EVER!
