The Best Telephone: Our Picks

Buying and rating criteria for telephones

To help you make the best possible purchase decision, we have collected and summarised all the criteria you need to consider. These criteria are as follows:

In the following, we explain what you should look for when buying and how you can make a well-informed decision on this basis.

Functions and operation

Since the telephone is a necessary everyday object for almost every person, there is a wide variety of features and functions in telephones. Age, limitations and the spatial situation can be decisive here.

Whether with large keys for senior citizens, a special colour scheme for people with visual impairments or a lightweight compact format for the home, individual functionality is crucial. You decide what your phone should be able to do. You should also keep practical aspects such as weight and (without/with) cord in mind.

Answering machines are one of the most important features your phone should have.

If you miss a call, the answering machine jumps on and, in the best case, diverts the caller to voicemail. The recording is analogue or digital. Normally, every telephone has an internal memory, which results in an individual total recording length.

Most devices can display a message about the receipt of new messages. The answering machine is listened to via the menu or a specific key entry. The messages left there can in turn be saved or deleted.

In terms of operation, most telephones are kept the same. The keys are in the same place and the commands such as certain combinations of numbers to retrieve messages are similar. There is even no difference in the choice of colour: a telephone always has a green handset symbol for picking up and a red handset symbol for hanging up.

Power supply

There is now only one way to charge your phone: You use rechargeable batteries that are charged when you place them on the charging station. You also need a mains adapter to supply the charging station with power. There are several charging stations available for each model. Depending on how many handsets you have, you may need to buy another charging station.


Every phone has an internal memory. This is mainly used to store mailbox messages. The amount of memory available for phone numbers is usually also a big criterion for a purchase. Depending on the model, a phone can store 100 to 400 phone numbers.

The same applies to messages left on the answering machine, which can usually store between 30 and 60 minutes of recordings. Otherwise, the phone only stores your commands to be repeated. There is a small limited memory for the call list.

Number of available mobile devices

Now you have the choice of deciding how many mobiles you actually need. It can be helpful to remember how many people use the phone and how many landline calls you need.

The more people live in a household, the more devices and charging stations make sense. If, for example, the purchase is for a company, you may even need five or more mobile devices. So depending on the provider and your needs, there are many options.

Guide: Frequently asked questions about telephones answered in detail

In this section, we explain the most frequently asked questions about phones so that you are well informed when you want to buy a phone.

Who is a telephone suitable for?

Basically, a telephone is suitable for every area of use. There is a wide range of models for young and old. Since the range is very comprehensive, you should have no trouble finding a phone that suits your individual needs.

A landline offers an important communication channel alongside the smartphone and is therefore very advantageous for the household. However, you can also connect your smartphone to your landline. For example, calls can be diverted to your smartphone when you are on the move.

The phone is reliable and has a long lifespan. The robust material that most phones are made of can withstand a lot. In addition, telephones are low in radiation.

What types of phones are there?

Your phone can be with or without a cord, with different charging options and even with different haptics. There are also variations in the telephone connection. The analogue telephone connection, ISDN (multi-device connection), the system connection and the multiplex connection are among the most common.

Most telephones also have an answering machine or certain functions that make them easier to use. Whether it has access to the internet and is therefore compatible with a router is also up to you.

How much does a telephone cost?

The simplest models start at around 30 to 50 euros, but the more extras you need, such as the number of mobile devices or connection options, the more expensive it becomes.

So most phones are in the 50 to 100 euro range. If you need more or special functions, the phone can cost 100 to 200 euros. However, this can vary greatly and depends – as already mentioned – on your personal requirements.

Price range Available products
Low-priced 30-50€ cordless phone with few functions
Mid-priced 50-100€ cordless phone with many features and accessories
High-priced 100-200€ fully equipped set with many special functions

What needs to be considered when buying a telephone?

There are so-called telephone tariffs that can be booked according to individual preferences. A distinction is made between tariffs for local and long-distance calls. The mobile network or a call abroad also play a role in the choice of tariff.

Apart from that, you should carefully consider the accessories when deciding which phone to buy. The right accessories are important when using your phone.

If you get the phone and accessories wrong, you may end up not being able to make calls at all or your phone may become unusable. You should avoid this problem at all costs and therefore buy the right accessories.


Telephones come in many different variations and designs. Your phone can be used both privately and professionally. There are different models and features that ultimately have to meet your individual requirements.

When buying, you should always bear in mind which connection you want, how compatible your phone should be, whether it needs to have special functions and, above all, what your phone should be able to do.

Hardly any other means of communication comes close to the simplicity of the telephone. Anyone can operate a phone and expand it as much as they want. Your personal wishes and usually also the price play a big role in your decision.
