What are landlines and what are their advantages and disadvantages?

These devices are means of communication that work through cables, and must have a landline to work.


In some cases, the advantages of having a landline phone at home are very clear, for example for people who live in areas where mobile phone networks are not stable.

A landline is not subject to variations in signal quality because it is connected by cable.

A landline is also advantageous in emergencies because it is connected to your address and even if you don't say a word, the emergency operator will know exactly how to reach you.

Also, in situations where better sound quality is required, such as in crowded places, or for those with hearing problems, a landline phone is often the best option.

There are other benefits too, such as the battery, which even in the case of cordless phones usually lasts much longer than a mobile phone. And in cases of power failure, the handset can often stay on even when the power goes out, as some are powered by the mains cable.

Finally, calls are usually cheaper from a fixed line phone, as operators usually offer special offers from fixed line to fixed line, and many of the calls people need to make in their daily lives are to fixed line numbers.

The downside of landlines, on the other hand, is that you can't be reached anywhere like you can with a mobile phone. The immediate availability of contact is essential today, especially for some areas of activity, such as for entrepreneurs, for example.

In addition, landlines have always been the target of telemarketing companies, which usually call to promote products or services. This used to be more common, but it still exists and causes nuisance.

Another common practice is scams, when malicious people call someone's landline informing false kidnappings, which, unfortunately, is very common.

Mobility is also usually a determining factor for people to choose a mobile phone, since you can take it anywhere, unlike what happens with a landline phone.

  • Signal stability
  • Emergencies
  • Sound quality
  • Longer battery life
  • Many are fed by network cable
  • Cheaper calls
  • Accessibility
  • Telemarketing
  • Scams
  • Mobility

Corded or cordless landline telephone?

One of the things to consider when choosing a fixed telephone is whether it will be wired or wireless, depending on the mobility you want to achieve with your device. One of the main faults of the wired phone is the lack of mobility it offers.

If you choose a cordless phone, pay attention to the range, as some have a long range and allow calls to be made even away from where the phone is connected to the network.

Wireless phones allow people who are doing two or more activities at the same time to hold the phone while doing other activities around the house. The problem is forgetting where you left the cordless phone.

The long-lasting batteries that exist today have also allowed sales of cordless phones to grow in recent years, and the price of cordless phones has decreased as technology has advanced. Nevertheless, the corded phone still tends to have the lowest price.

Price Cheaper More expensive
Power They are connected to the energy Batteries must have a long life

Purchase criteria: Key features to evaluate landline telephones

There are certain features that a landline phone should have, according to the needs of each consumer. Below, we have prepared a list of what is essential to observe before buying a landline:

  • Answering machine
  • Accessibility
  • Possibility to block unwanted numbers
  • Digital or analogue
  • Caller ID
  • Contact book
  • Battery life

Below we will further explain each of these features, so you can make the best choice when buying your landline phone.

Answering machine

One of the things to think about before buying a landline phone is whether you want it to have an answering machine or not.

An answering machine can be useful to give out your mobile phone if you are not available on the landline, or to leave some other kind of message for callers.

If you want to choose a model with an answering machine, check that it is easy to record a personal greeting and also what the memory limit is for messages left.

An answering machine can also be useful in case of travel, because, since you will be away, it is important to have at home or in the office some way to record the messages.


One of the important items to look for in a landline phone is its accessibility, that is, how much the design of the device facilitates access to it. Examples include large buttons and display, which allow people with sight problems to feel more comfortable with the handset.

The volume of the phone should also be noted, so that people with hearing loss can turn it up to notice when the device is ringing. Lighted warnings when it rings will also make life easier for people with hearing problems.

Ability to block unwanted numbers

Some phones allow certain numbers to be blocked which is useful in cases such as recurring telemarketing calls.

This feature is usually called "Black list", and works when unwanted numbers are added to this list.

This provides more tranquility, since some companies are usually very insistent in their sales by telephone. Avoiding prank calls is also an advantage.

This telephone blocking is also useful to definitively block people who try to apply scams such as false kidnappings over the telephone.

Digital or analogue

Analogue phones are cheaper, and analogue transmissions usually have good call quality and little interference.

The digital signal is faster because the circuits are simpler. In analogue telephony, as the circuits need to deal with a variety of situations, the system works more slowly.

A telephone call made digitally can even be transmitted via the internet, in a service known as Voip.

Many people believe that when we talk about digital and analogue telephony, we are talking about keypad telephones and disc telephones respectively, but this idea is not correct.

Caller ID

Caller ID is an item that many people consider indispensable nowadays, mainly due to the use of mobile phones and the habit of always seeing who is calling.

The caller ID works through a device that transforms the frequencies into binary language, so that it is then possible to decode the signals of who is making the call, and consequently recognize the number that is calling.

Through a call identifier it is possible to choose whether you want to answer a call or not. It also makes it possible that if you are in a meeting and someone calls you, for example, the number is recorded for you to call back later.

Contact schedules

The phonebook is another feature of your landline phone that makes it easier to identify calls, as the name of the caller appears on the display.

This feature should be placed manually on the phone by following its instructions. Saving numbers in your landline phone's agenda is also important to have these numbers stored in case your mobile phone is lost or stolen.

Normally the phone only allows a certain amount of names to be recorded, so pay attention to store only the most important ones.

Battery life

One of the problems with a cordless landline phone is the battery. Even though they are manufactured with increasingly durable batteries, they can run out of power in the middle of a call.

The wired landline does not have this problem as it is always connected to a cable. However, the mobility it offers is very limited.

Those who have a cordless landline phone should always pay attention to the battery level, so as not to miss any important calls due to lack of charge. The most common models usually support up to 6 days in stand by.

In addition, they also usually support about 8 hours of continuous conversation or more, so pay attention to these details when buying an equipment.
