Anonymous users2024-02-05EVDO needs mobile phone support, and while there are no issues with either the base station and the technology, I personally don't think it's necessary for three reasons:
2. There are few EVDO terminals supported, and the R&D cost of the terminal is too high;
3. It's not practical, why do you say that, at present, wired broadband is generally stuck between 1m-4m, and you need tens of megabytes for wireless networking, is it possible, the total capacity of the network is here, you can't be fast; Recently, Sina reported on the worrying report of high-speed rail 3G Internet access, Unicom HSPA+ The so-called 21M actual effect is only, the signal is still intermittent, far inferior to Telecom's EVDO; In addition, the bandwidth of the base station is shared, and the bandwidth of the base station is limited to the base station and the mobile phone, not what you access**.

Anonymous users2024-02-04Yes, but there will be no large-scale upgrades, and places with high data service requirements in large cities will be upgraded to version B. The B version of the phone will be released, but not by much. The B version of the data card is already available.
Due to the explosive growth of data requirements on the mobile Internet, it is possible that telecom will also directly connect to FDD-LTE or WiMAX.

Anonymous users2024-01-30Dear users, hello:
Due to the influence of frequency bands and other aspects, 4G cannot be as good as 3G signals, so in many regions, Internet access still relies on 3G, especially in the first two years of 4G commercialization. So you don't need to worry.
Even if 4G comes, your 3G** will not change if you don't want to change it yourself.
If you need to apply for 3G**, you can go to the online business hall of Anhui Telecom to check.
If you have any questions, you can go to the Anhui Telecom online business hall to consult the staff, Anhui Telecom has a mobile phone New Year's Eve delivery event recently, you can check it when you have time, I wish you a happy life!

Anonymous users2024-01-27If you used to use a 4G signal and haven't changed your phone's settings recently, then it's likely that the 4G signal is not good in your place, so the phone automatically drops to 3G mode.
If the phone has always been in 3G mode, then you have to see if the network standard set by your phone is 4G first.
At present, although 4G has begun to be popularized, the signal still cannot be fully covered, and 4G signals cannot be found in some places.
I feel that the efficiency of the telecommunications staff is poor, my home network speed last year dropped the line twice on the line did not fall off a block for a month before I repaired, what is the problem of the computer room, this is not more than two months after my computer can not go on the line and it has fallen even more, it has also dropped a block for half a month, every time I hit ** to say that the problem of their computer room, I think it is a person who is slower than a pig should also be repaired, the network speed is still motionless on the card, I also heard a friend say that people who know the telecommunications company The network speed at home can be adjusted to be faster than the network speed at other people's homes, because the first time I dropped the connection, how long did it take to complain to them I suspect that the second time the connection was dropped, the network speed stuck like this is purely their revenge for me, that is, it is not revenge for wronging you, so repair a dropped computer room for half a month at a time? And it's done twice in less than three months? Is this what you are capable of? >>>More
Then you just wait to be sued.
You've signed an agreement when you used to hold your phone. I don't know how many years it has been signed? Will telecom not care if it breaks the contract now? At that time, it will not be as simple as paying off the arrears. Let's pay the liquidated damages for arrears together. >>>More
Anything that is obviously cheap is basically a lie.
It's all under the guise of fooling people. >>>More
