Senior Phone with Strong Antenna, Large Battery & Capital Letters: Grandma-Proof Options

I'm looking for a grandmother's phone with capital letters, and not like in some emporia only on part of the menu.
The key aspect, however, is coverage, or rather the lack of it at grandma's home. The current telephone is more unavailable than on the web. An additional requirement is a place to attach the leash and a large battery because grandma forgets where the phone is and whether it is charged.

Anyone have access to compare phones in this respect? I was thinking about the external antenna, but cable losses can offset the profit, and grandmother can easily damage the cable.

Buy her used but functional old Nokia and it will be a problem. "2-steps-GSM" on Independence, there is a shop with cheap old phones under warranty. They have everything exposed on the allegro. Buy a new battery and grandma will be happy. Nokia 3310/3410/6210 / 6310. There is more to it than ever and they really have coverage. Where my smartphones do not work anymore (basements, elevators) the old good 6510 and 8310 often have even half range. Battery? The new battery in 8310 lasts from 12 to 18 days.

Maybe Nokia 6310i? The battery and range was good on this model.

Small letters: / at the beginning of my youth phones came to my mind but it is stuffed on these screens terribly.

What do you think about Alcatel OneTouch 2008G? How to check if it will catch the signal?

First, you start by switching all the phones you have manually in 2G so that the phone does not log in to 3G or 4G, if any. In my home 3G has 2 range lines. 4G has a line or two while 2G is full. To lose LTE, all you have to do is put your phone in your purse and leave it somewhere in the hall. If the phone is set to 3G or 4G it will lose range and 2G never.
And as for older phones, in fact, their big minus are small displays, but the 6310i has sharp backlight and the font itself will not be so small compared to a smartphone on which icons and everything else are also small.
I bet Grandma's internet is superfluous. I also think that SMS / MMS support will also bypass it. For the elderly, the most important is quick and easy access to the phone book, visibility of coverage, battery charge, and easy dialing and receiving calls.
And Nokia 7110 and 6250?

Grandma's phone doesn't have 3G and LTE, that was the first thing I checked. The nearest BTS is 2.71 km, but the forest is doing its job. To give it a try I gave babulce his time 2330 or something similar and found that the buttons are too small and can't see what number he is dialing. If you use a magnifying glass at home, there is a lime outside the house. The criterion of small buttons leaves almost exclusively the phone directed strictly to seniors. I even thought about innovation (Halo X from MyPhone) but still the key will be coverage ... because what about the fact that grandma will be able to dial the number if she still won't call anywhere.

This is not exactly the case with 2G and 3G. I switched the phone myself to 3G because I have much better connection quality on the 1st range than on the full 2G range in the city. Older phones had lighter antennas due to SAR.

The issue of coverage is maybe the problem is in a particular network it may be worth changing the operator if it's not a problem or at least replace the SIM card which may have a lot of errors.

The networks have already been checked and there is orange - one of the two operators on the nearest BTS. We know - in a city a given frequency may be disturbed or overloaded - but here we have a village.
Network manipulation has been done. It is about the number of phones available for seniors, because among smartphones there will be something that keeps the range (e.g. Ace 4 LTE).

Hello, I found this thread accidentally and I also have the same problem with my mother-in-law. Currently, she has the Maxcom model MM462BB. Unfortunately it doesn't work well. I tested her apartment with old Nokia and it worked, but Noka's mother-in-law can't handle it either.
Maybe you solved your problem and can you suggest something?
best regards

I bought Alcatel 20.08 on the net, not for idiots, for 159. Grandma is happy and finally you can call her.
I recommend buying online, you can always return it.
