Great phone for seniors. Big buttons and loud!
For my mother. Perfect for a senior citizen, although programming is still a challenge for her.

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 for5-seconds and the phone will restart. Enter correct date.

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

Will not hold a charge at all
The phone I received worked perfectly well when sitting on the charging base. But as soon as it was removed from the base the phone would die. I tried contacting the seller willing to exchange the phone for one that worked, but never heard back from anyone. I finally had to get my money refunded through Amazon customer service instead.

Worked as should
Phone worked good. But my husband with dementia still couldn’t use it. He always was locking it up or shutting it off. I programmed my number in as m1 and he couldn’t remember. Not phones fault. But to hard for him to use.
