Sturdy, easy-to-use phone for elderly parent.
Very good phone for my elderly mother with Alzhemiers. Big buttons and a simple layout is perfect for her. She struggles with smart phones. Its clear and always keeps a solid connection. The phone seems very sturdy.

DONT BUY ARTFONE!
This is the worst phone I've ever owned and I've owned dozens. It keeps dropping calls and the quality of the audio is so bad I must end many calls. My advice... DON'T BUY AN ARTFONE!

Just what the granny needed!
Was exactly as expected and what was needed for a grandparent who has a hard time seeing the smaller screens and mobility issues with her fingers. While it looks hefty in the picture, you never know until you actually get it - I was surprised by the generous size and ease of use. We were able to help her get all of her contacts in and explain how to use the phone easily. My only recommendation would be to print the instructions in a larger font. Seriously - this is marketed as a big button cell phone for seniors. Even I had a hard time reading that manual.

Great phone but freezes in cold weather
For my mother. Perfect for a senior citizen, although programming is still a challenge for her. Update. The screen freezes in cold weather. Live in Vermont. Buyer beware. Poor mother is disappointed. Bought in June so could not check on the cold weather performance until after the return window expired.

Good phone for seniors ❤️
This phone is perfect for seniors. Easy to use. Decent size and contain all the functions a senior need. I bought for my mom (85 year old) and she love it.

won't work where there are fewer bars.
we can't get the phone to work after 2 trips to town. It only works in town. Very weak reception for some reason. Won't work out in the country where we are even though our other phones do.

Perfect and simple
Received it today and it’s a perfect simple phone for my father that’s 87 years young. Large buttons and loud speakers both in and out. Works on T-Mobile

Early impressions
My pre-use assessment: Design layout- 5stars, Readability keys and screen- 5stars, Tactile feel of keys- 5stars, Gen. impression- 5stars. Best provider for this phone (in CT) is T-Mobile. Poss. downsides: the rear cover needs to be carefully pried loose from bottom slot. The little pegs which hold it in place will pop-up as you lift the sides slowly. One other thing to note: the power adapter cord and its base-socket are not very sturdy--plug has to be inserted carefully to avoid cracking the connector. This is in contrast to the seemingly sturdy build of the phone. The 'user-pamphlet' is extremely limited in operational content. Re: the upgraded battery, if left off the charging cradle, it will gradually discharge over ~12days, even if the phone is not used. I don't know whether this is typical for cellphones (?). **NOTE** If you want to use standard US date format, you'll have to select this in Settings. Default setting is Day/Month/Year. This is the perfect phone design for me. I don't want a smartphone. Just tried the T-Mobile nanoSIM card and all's well. Finally, I want to note that the marketer of the Artfone line "SZ CoolcellTechnology" was exceptionally courteous in my one contact with them. Jun19,2025 Update:: Note that if you remove and replace the battery (for a full reset) you will see a black screen, "Gladys, my phone won't turn on" Phone is not dead. Just hold-down the Red 'off' button for 5-seconds and the phone will restart. Enter correct date.
