The Evolution of Mobile Phones

Today on National Telephone Day we are looking back on the evolution of the telephone from the first telephone until the eSIM capable devices we see on the market today!

Just over 100 years ago, the idea of instantly chatting to someone anywhere in the world seemed impossible and to do it with a video connection would be insanity to imagine.

Today, we’re going to show you some examples of how the phone evolution have looked like.

When Alexander Graham Bell invented the first telephone back in 1880s people were debating why you would want to hear someone’s voice when you could just send them a telegram instead and over the years, we’ve had a lot of different types of telephones, including rotary dialling phones, candlestick phones touch tones, cordless phones and of course the mobile phone.

Phones early 1900

The first rotary dial was invented in 1896. Rotary phones worked by generating pulses in a certain frequency range based on where the rotary dial turned and I am sure most of you reading this over 30 years of age has tried one at least once in your life?

Candlestick phones were popularized throughout the late 1890s to the early 1900s.

The phone was separated into two pieces: a mouthpiece also called the candlestick and a receiver, which was placed in your ear when you were placing a phone call. Interesting to note that original phones are now worth over $1000 and a lot more if you happen to find a real rarity.

Phones 1940s

The first touch-tone phone was invented in 1941. These phones used tones in the voice frequency range – much different from the pulses generated by rotary dials. You pressed the buttons on the phone to make a phone call.

Phones 1970s

The back then “modern and innovative” cordless phones started to hit the market in the 1970s and in 1973 Motorola released the first mobile phone. It was not really sized to fit in your jeans pocket, but very flashy for them who bought them as they weighed just over a kilo and you had to charge it every 20 minutes.

Phones 1980s

In the 1987 movie Wall Street you could see the The Motorola DynaTAC 8000X also named ‘The Brick,’ showcased. This phone was not for everybody with its hefty price tag of roughly $9000 dollars.

You could also in the 1980s purchase a Nokia Mobira Talkman that is the size of a briefcase, not great to be carrying around, but very flashy indeed.

Phones 1990s

This is when we started seeing a lot more mobile phones coming through and the prices started to drop so even “common people” had the chance to stay connected on the go.

We started to see the fancy “flip phones” and Nokia launched their 5110 that kept everyone busy playing snakes, one of the first phone games on the market.

Phones 2000s

During the 2000s the phone market has exploded because this is where the epic smartphone era began. In the start of 2000s companies such as Nokia, BlackBerry and Windows released models featuring keyboards or touchscreens and access to email and wireless internet. A big turning point for the smartphones was the unveiling of the iPhone in 2007. After this launch, we have seen a trend on the market with thin devices with large screens rather than physical keyboards with the ability to download or purchase applications from a centralized store.

The newest groundbreaking technology added to smartphones is the eSIM technology. This new technology enables manufacturers to develop devices without the need for the physical SIM card as we have seen in earlier devices. This will enable them to build even thinner or smaller devices and it puts the power of connection back in the hands of the consumer. is a great example how the eSIM enables the consumer to #getreadytoroam on their terms.
