What is the difference between a 100 3G data card and a 180 data card

Support 3G network card3G network card, backward compatible with 2G mode, click to see details, such as mobile 3G TD-HSDPA mode card is compatible with 2G network and GPRS Edge mode mode; The CMDA2000 3G SIM card is compatible with the CDMA1X mode of the 2G network. Click to see the details The biggest difference is of course the speed, the 3G wireless network card in the 3G network coverage area, the speed is much faster than 3G. Click to see the details of the current 3G wireless network card, the theoretical peak value that can be achieved is 3m or more, but in actual use, because of the strength and stability of the wireless signal, this is equivalent to the average speed of 512k1m The average speed of wired broadband is generally 70100K per second, if you use it to browse, email, chat, fight landlords and the like, it can guarantee that if online games, movies are not very fluent.

Click to see the details (mobile TDSCDMA, China Unicom's WCDMA, telecom CDMA2000 are almost the same), click to see the details If the county, township, most areas do not have a 3G network, it will automatically switch to 2G network operation, 2G network, EDGE is the fastest movement, the actual ** speed is about 20K per second, Telecom CDMA1X Secondly, the actual ** speed is about 813K per second, the actual ** speed of China Unicom GPRS is about 5K per second, Smoother browsing on the web is not guaranteed.

Signal receptivity is not the same.

You get what you pay for, and it is recommended to sell more expensive ones.

It's big, there's 200 hours, there's 100 hours.

In addition to the different tariffs of these two cards, the 3G network card only opens SMS and Internet access functions, while the mobile phone card also has a voice function in addition to the phone card, which can be called**. 3G Wi-Fi SIM card** generally cannot be used in a 3G mobile phone.

Can't you just give it a try?

1. The traffic algorithm of the two cards is the same, and the upper ones are just cheaper. 80 blocks are the ** of the business hall.

2. The software you connected to with your mobile phone this time must be updating. Chat QQ as long as it's not ** won't use so much. 20M traffic, if only text chat, you have to receive and send 1 million words...

3,The traffic of playing online games for one hour is about 20m,1G can play for 50 hours,It should be enough to see how you use it。 Be careful not to ** large files and do not watch movies. Our Unicom business hall is introduced as follows: "100 hours of normal Internet access, or 2-3 ordinary movies" with 1G traffic.

Check it out at the end of the month.

3G is used to convert the wireless signal of China Mobile Unicom, while WiFi is used to convert signals such as wired networks, such as your own router, CMCC.

The 3G network card costs money, about 300 yuan a month, and the wifi network card is free of charge as long as the Internet is connected to the wifi.

3G is used for Internet access, and the wifi world is used to collect WiFi signals.

3G network card means that the signal is good, the coverage is large, there are a variety of signals for you to receive, the best is in the wine café, some places down is the 3GW network, and finally 1X. 3G signal is relatively more stable than 1X, but it also depends on the network card equipment you use, Huawei is relatively stable, but ZTE is a little flawed. Huawei has two models, one is sent after you get a network card, and the other is given to you if you add 300 fast.

Thank you for the trouble to adopt!

3G is the meaning of the third generation of network technology, you use Tianyi 3G is the CDMA EVDO network, the highest bandwidth is 2 points and a few M, and 1X is the second and a half generation of network technology, only more than 130K bandwidth, so the two will be very different. According to what you said, the list says that you can go for 80 hours, that is, you choose 80 hours**, that is, you are billed by the duration, not by the traffic (these two are optional), so the 3G network you use (instead of the 1X network) is billed by the duration**.

If you keep jumping 1x, you will be scammed, and you can only endure the speed of shit for 80 hours, which is slower than on your phone.

1x is for those who do not have a 3G signal, 1x is more than 100 kb at a network speed, 3G is theoretical), and 11M s when connected to wifiThese three options use which one you want to use,These 80 hours,It refers to the total time of using these three,If there is a wifi signal, use wifi,If you don't3G,If you don't, use 1x,In addition, Tianyi is not billed according to traffic,In these 80 hours,No matter you use 1000000GB,It's still the same。 But don't exceed the time, if you exceed it, it will be charged at 3 yuan per hour, and if you exceed it, it will not be charged according to the traffic according to the time, which is just the opposite of moving, and the traffic will not be charged according to the time when moving.
