Dual SIM Card Micro SD Card Adapter (2 Pcs) for Android Smartphone,Ultra-Slim SIM Card Extender for Samsung S7 / S7 Edge / S8 / S8+ Huawei Mate7/8/9 Xiaomi Lenovo (Micro to Nano)

is not working, is a waste of money.

Meh - it gets the job done, kinda. It's a bit jankey and cheap and makes it so my phone case doesn't fit properly. The case not fitting properly wouldn't bother me if the volume buttons still worked. I have to pull the case aside to work them. Not ideal, but better than nothing I guess.** Update 8/9/18 **Removing this device from my phone caused something in it to break and it no longer works.Also, as of June 2018, Samsung released a software update that prevents you from using two SIMs and an SD card. They popup a non-closable message that says "there's something in your tray that shouldn't be there" or similar wording, and you can't use your phone until you take out your second SIM or your SD card. That renders this little device useless. Please don't buy it and expect to use two sims and an SD card unless Samsung disables this stupid message.

Excelente artículo lo recomiendo un 100%, cero complicaciones a la hira de instalarlo y mi teléfono celular Huawei P10 reconocion inmediatamente las dos Sim y la memora microSD. PERFECTO

It did function well, but when I tried to remove the sim inside the phone tray, and have to remove also the dual sin, this broke apart, it is very fragile so treat with care

Doesn't work. Waste of money!

I bought as the description said, will work with S8 but found it's not fitting to existing SIM tray, so has to order dual SIM tray..waiting for it and will try once it reaches. If still doesn't work, may need to start a return.

Excellent product, I recommend it 100%

This product is too short in length for the S8 and it does not work. None of the sims are recognized.Would like my money back.
