Ask for 3G experts to come... Ask for help from Unicom 3G experts

The mainland is going to open TD-SCDMA

I haven't heard of a mobile phone that supports TD-SCDMA yet, so maybe I'm lonely and unheard.

You're right, but after 2 or 3 years, when Unicom's WCDMA network matures, it's hard to say whether your N73 will be eliminated by you.

You're absolutely right, after the 3G network is turned on.

3G networks are limited to a very small part of China, and there are still many parts that have not yet built a 3G network platform.

No, you must be on the same model to make a 3D call.

Mobile's TD-SCDMA technology is not very mature,The network speed is not ideal,The models are basically produced by GUO,If there is no subsidy, it is highly recommended,The use of telecommunications is CDMA2000 that is, EVDO system,Stick GUO and a small number of other countries are in use,The network is general,The phone bill is also cheap,But now there are fewer models,There is Unicom's WCDMA。 It is a relatively mature and universal 3G system in the world, some ** tested the speed of 3G of 3 companies, WCDMA is the fastest, that is, Unicom is the fastest, but **is a little not close to the people,**expensive,And I heard that the network coverage is not very good (just heard),But Unicom's models are the most,Many revision machines (parallel goods) want to use 3G must use WCDMA,The high-end models of major mobile phone brands are WCDMA,So you can play any mobile phone you want,If you have money and want to experience high-speed Internet access, Recommend Unicom!

Hope it helps.

China Unicom's 3G is better; There is no difference between mobile 3G and 2G.

In the network settings, just set 3gnet in the APN.

Where there is a 3G signal, you will go to 3G, and if there is no signal, you will be 2G, and that's it.

The 3G2G signal on your mobile phone is always switching, which means that the 3G signal there is very poor.

Unicom signal poor recognized.

m: The unit of pricing for multiple content (images, streaming services, etc., such as watching a paragraph or a song), and the value of a multi-content is n m. Of course, this is the fee you will charge for choosing a service on the official website of China Unicom 3G!

Similarly, this is also the cost of choosing a service on the official website of China Unicom 3G, but these are clearly priced. Whether you incur a fee for browsing other web pages through your mobile phone to browse the news, ****, **, ** or not should be subject to the description, but generally do not incur a fee, only deducted from your 300M domestic traffic.

I bought the generation of iPhone, 3500 to start, 2 generation I bought at the end of August last year, 4900 to start, I know a lot about it.

1.The latest is iphone3gs is not iphone3g, compared to iphone3g, it is more powerful than iphone3g, and it runs faster, but for us, it is basically not felt, Unicom released iphone3g, that is, the 2nd generation, no wifi function, it is not recommended to buy, the mall does not sell iphone 3g, because this is parallel imports, iphone3gs and iphone3g are sold in some places in zhongguancun, it is recommended to buy those parallel goods, because with wifi function.

2.At present, it is recommended that you buy the 2nd generation, the first generation is a metal shell, which is easy to scratch, and the 3rd generation ** is higher, the function has basically not changed, and it is not recommended to buy.

And wireless Internet access are two concepts, parallel goods and licensed iPhones can support China Unicom's 3G network, that is, WCDMA

4.There are only three models, which are the so-called 1st generation, 2nd generation, 3rd generation.

5.It is recommended to buy parallel imports, either the American version or the Hong Kong version, some people suggest buying the Hong Kong version, there is no need, because when you go to the parallel trader to buy the American version, he is now cracked to give it to you, and the American version is slightly cheaper than the Hong Kong version, and the Hong Kong version is much more expensive than the American version when I bought it.

First of all, the back cover of the first generation of iPhone is metal, which feels the best, and there are relatively few on the market, and the back covers of the second and third generations are all plastic, which is easy to damage.

Then the performance is the strongest in the three generations of iPhone3GS, and the main frequency of the CPU can catch up with the low-end graphics card.

The parallel iPhone not only has 3G but also has a WiFi function, which is not available for licensed goods, and parallel goods are much cheaper than licensed goods, so it is recommended that the landlord buy Hong Kong lines, if you can't buy parallel goods, it is also good, try not to buy licensed goods.

At present, the licensed iPhone3GS bare metal** is around 4999.

Parallel goods are under 4,000 yuan, and my classmate bought an iPhone generation in Hong Kong for only 3,200 yuan.

It is recommended that the landlord go to the major ** to see, compare, and try to suffer as little as possible.

3G is not the latest, the latest is 3GS, the CPU frequency is 200 Hz higher than 3G, and the memory is 128 megabytes higher, which is much higher.

Unicom's iPhone does not have wifi (wireless network) and is castrated. But GPRS and 3G networks are possible.

The Hong Kong version and the American version or the Italian version are smuggled goods, that is, parallel goods.

In fact, parallel goods are better than licensed goods, and Unicom's licensed goods are produced by an automobile factory in Shenzhen, and the cost is relatively low. Alas, we Chinese are so confused. But fortunately, there is an after-sales service. In the end, it's up to you to choose!

The current 3G wireless network speed is not very suitable for playing online games, especially large-scale 3D online games, even if it is connected by telecom wifi, it is also very stuck, because the speed is really too slow, and it is unstable, resulting in too high latency, and the QQ or web page with low requirements for network delay can also make do, as long as the line is not interrupted, as for the 3D online game, there is too much data to be sent and received at the same time, and the delay is too high, which will cause the data to not be transmitted and received normally. Therefore, the server will judge that you are offline, that is, you are disconnected, so there is no way to solve your situation.

The same place can't play at 8 o'clock in the evening and play after 12 o'clock in the evening It's very good This problem is very simple, after 12 o'clock in the evening, most people have rested, so the requirements for the use of the 3G network are reduced, the load is reduced, and the speed goes up, just like the busy street in the early hours of the morning, how fast do you want to drive OK, of course, you have to be not afraid of speeding fines.

Playing big games with 3G is burning money.

3G's slow and 3G alternative to 3G makes it easier for you.

2G is definitely not enough, if it is used by a mobile phone, it is enough. The operator's ** settings are unreasonable, and do not take into account the minimum amount of traffic required to open a page.
