Now all kinds of WIFI coverage, wireless routing, 4G traffic packets. ...
It seems that overnight, goodbye has been futile.
With the development of science and technology, the progress of society and the great changes in communication methods, how long has it been since I started writing?
Hongyan sent a book to know that she was an old friend. Clouds and smoke come and go, like knives and pens.
There are gains and losses.
In the era of 2G network, at that time, telephones could only send text messages and make phone calls, but could not access the Internet. Unforgettable memory is that people at that time had to walk to the middle of the road when they called, as if only one side of the sidewalk would have no signal. Standing in the middle of the road, the signal is full immediately, and the phone call is particularly loud. One is: hey, you have to shout three or four times in case others don't know he's on the phone. Every time you see such a person, you want to get a slipper.
The full name of the 2G era is the second generation mobile communication technology. A typical representative event is that mobile phones can send text messages in addition to making phone calls. I bought my first mobile phone when I was studying, just in time for this era, so I still have many unforgettable memories. Pick one or two points to share with you!
The package our students used at that time was the campus network package, with a lot of text messages every month and a mobile package of 3000 yuan. Unicom sent it casually. The earliest Unicom number I used was the one that was sent casually. I had a girlfriend then. You can make up for this memory of texting! Not only couples, but also classmates talk about things by SMS, sometimes sending a sentence or two. Where is it? Classroom, which classroom is it? 3. Do what? Self-study ... It can be said that the text transmission between black and white screens became our greatest interest in that year. Everyone is typing with their heads down on the road, no less than brushing WeChat today!
Although Unicom has no restrictions on short messages, it also has one of the biggest shortcomings, that is, the network is unstable, and sometimes the short messages sent take a long time to receive, so I have encountered such a very specific thing. At that time, my classmates and I were running a magazine. One day, a partner saw me very angry and said that he had sent me several information consultations. I ignored her. As a result, she finished it, and I received the message from him yesterday. It's all Unicom's fault!
My Unicom number is very good. I chose it for a long time, and the ending is very memorable, 52525, but because of the bad network, I finally changed it. Later, a teacher elder sister with a good relationship graduated from work and gave me his number. After that, I changed it to a mobile phone number. In order to compete with China Unicom, China Mobile has cooperated with mobile QQ. It can be said that in the 2G era, we enjoy an instant messaging tool that is always online. Now think about it, we are really lucky!
There are many interesting memories, I hope everyone has similar memories! ! !
The deepest memory of the 2G era is the 70M monthly subscription. Now 70 meters of traffic flows away every minute?
