Is Samsung phone D7898 a triple play phone? What is the difference between 2G and 3G networks?

: It's not a triple-play phone, the most fundamental difference is that the speed is different, 3G is obviously faster than 2G.

Samsung mobile phones can use 3G cards, the difference between 2G and 3G is mainly in the network speed, 2G is an ordinary card, 3G card is a high-speed Internet card, 2G card Internet access, the browser needs a certain amount of time to load the web page, 3G card Internet access, the browser belongs to the state of high-speed operation, a click on the web page you want to browse to enter, loading an ordinary web page is basically less than a second (this also has a certain relationship with your mobile phone), if you usually use your mobile phone to see some web pages or knowledge, it is recommended to buy a 3G card, When the network speed of the ordinary card (2G card) is not good, browsing for more than ten seconds does not come out of a web page, at this time it will also affect our brain is in a state of excitement and desire to absorb knowledge, and it will also affect our mood, if you use it to chat WeChat or QQ, the ordinary card will be.

2G mobile phones can only use 2G network, which is the so-called 5 yuan 30M traffic, very bad, 3G network can use 2G and 3G traffic, 1 yuan 500M, this is the biggest difference, now the new machine is basically 3G, 2G mobile phone you still don't buy, 2G network speed is basically below 20KB, 3G is generally above 150KB.

One is fast, the other is slow.

It should be Samsung's machine with a bad signal.

Are you asking about a 3G signal or a 2G signal? And does your phone support 3G? Does your location support 3G signal? There is no 3G signal in some places right now.

Hello, you can refer to it here.

It depends on your mobile phone model, and whether your card is suitable or not, like my mobile phone Samsung S3, which supports Unicom 3G, but uses other cards like mobile or telecom, etc., it can only support e-network.

It depends on the support of this model that does not support 3G networks.
