artfone A400 4G Volte Big Button Cell Phone Unlocked for Seniors, Senior Cell Phone for Elderly & Kids with SOS Button, 2MP Camera, 2.4" Display, Loud Speaker, Charging Dock,1800mAh - Silver

Great phone to use as a substitute to a land line. Love the large buttons. Works great with Red Pocket (T-Mobile MVNO). Very simple, as expected. Easy setup, but installing the nano SIM was a little tricky as the SIM slot does not open, you have to slide it in. A little tuck and it worked. No setup needed really after SIM is installed and phone turned on. I love the night feature letting you automatically turn the phone off at night and on in the morning. Speaker is loud and clear. Network search shows also AT&T, but no Verizon. It may work with AT&T but not sure.

I bought two of these and neither one worked properly. I'm a patient person. tried everything including changing my carrier and changing my sim card. Hope you have better luck.

Phone was confusing for my father in law. The light button is in the wrong spot so when he held it the light button was turned on. Not easy to use for elderly. Too small.

This little beauty works great on Tello, who uses T Mobile. It is perfect for my mother in law who is 86, and hates any phone that doesn’t have buttons. It’s easy for her to use and, best of all, she can hear people talk on the speakerphone. If you are looking for a base phone that works and isn’t junk, this is for you. I am so glad I got it.

This is about the "frequently bought with" advice on the Amazon page. I took its word and bought the ULTRA SIM card, only to find out that it is NOT compatible with the phone. :P

I am very pleased with the phone.

Appears to be cheaply made. Not as easy to use as described. Did not keep, sent it back

My elderly Dad is completely “old school”. He doesn’t like cell phones and has no desire to learn anything other than what he knows. He also doesn’t like the thought of having to call people outside of our family in an emergency. This phone was the perfect fit for him! Big BUTTONS (not a flat screen) and it has the ability to add selected numbers to the emergency button on the back of the phone. It’s small enough for a pocket and fits into the flip phone pouches to attach to the belt. It comes unlocked so I was able to add it to my cell service provider within minutes. I couldn’t be happier with the purchase!
