Unihertz - Unihertz. This little phone is amazing. I got mine yesterday, and I have been having fun loading software and apps on it. It has a removable battery, will accomodate TWO Sim cards and a Micro SD card for additional storage. I left it on last night and not on the charger and it still has 42% charge left. It is almost too tiny to press the icons and keyboard; but, careful tapping gets the job done. It has Android 7.0 and is snappy and works fine. I took the SIM out of my LG V20, which had not been used in a while, and it works great. I can carry this tiny little phone in a pocket or on a key chain. Call it the anti-phone. Don't want to spend $1,000 on a phone for your kid? Get this for $140 or less. Pop in a SIM and you are good to go.
