After the popularization of 3G, do you need to change your mobile phone? What about the mobile phone

Whether you need to replace your phone.

Regardless of which company's 3G service [2] is used, it will need to be replaced with a 3G mobile phone. At present, 3G mobile phones have not been listed on a large scale in China, but 3G mobile phones developed by various mobile phone manufacturers will be launched one after another during the year.

On the premise of using 3G mobile phones, mobile and telecom users can upgrade to 3G without changing their mobile phone number. Among them, China Mobile launched the "three noes policy", that is, all China Mobile users do not need to change their mobile phone number, do not need to change their SIM card, and do not need to go to the business hall to go through the registration procedures, they only need to insert the original mobile phone SIM card into the 3G mobile phone.

In addition, according to the plan disclosed by China Telecom, by the end of March, all users, including China Telecom 133 153, can use the current 189 "Tianyi" service.

China Unicom said that it will open WCDMA in May, and Unicom users can directly upgrade to 3G without changing numbers.

You don't need to change the SIM card of the mobile phone, and you don't need to change the mobile phone when the 2G network can still be used.

At the moment, 3G is not that fast.

Your card will still be available for 2-5 years.

This problem is easy to solve,You buy parallel goods 5320 It supports WCDMA,It is Unicom's 3G network format,Wait for 3G to popularize with Unicom,No need to change the phone!

I will definitely change my phone after it is popular, but I don't know what kind of phone you are using now Nokia's high-end mobile phone support.

If you change your mobile phone, China Mobile promises not to change your card, number, or registration.

Foreign countries are basically in CDMA format, and in the future, if you really buy parallel goods and want to feel 3G, you really have to use Unicom's card!

There is a move to have. Their signal is TD-CDMA... Independent research and development, so there are fewer mobile phones supported. You don't need to change your phone number. Those who support TD-CDMA are mobile 3G mobile phones.

Yes, you can not change the number, the original number is upgraded to the 3G number, the card must be changed, the mobile 3G mobile phone refers to the mobile phone that supports the TD-SCDMA standard, only China has it in the world, it is a patented technology, and the mobile phone sold on the market 3G must be installed with Datang's TD chip, so many mobile phone manufacturers do not support mobile 3G, the most typical is iPhone, WCDMA system is used worldwide, that is, Unicom's 3G

The 3G mobile phone card can be used on a 2G mobile phone, not only on a 3G mobile phone.

If you put a 3G SIM card in a 3G mobile phone, you can use the 3G special service. For example: Visual**.

There are 3 conditions that need to be met to dial Visual**:

1. My own is a 3G mobile phone 3G number.

2. The other party is also a 3G mobile phone 3G number.

3. Both parties are within the 3G signal coverage range when dialing.

It should be noted that Mobile's 3G uses the TDSCDMA standard, and Unicom's 3G uses WCDMA, so if the mobile 3G number is placed in the Unicom's 3G mobile phone, because the standard is not supported, it is not possible to use 3G special services.

In the same way, China Unicom's 3G number is placed in a mobile 3G mobile phone, and it cannot use 3G special services.

When you buy a 3G mobile phone, you have to take off the battery, and look at whether it is TDSCDMA or WCDMA written on the back cover, and you will know whether it supports mobile 3G or Unicom 3G.

The 3G network is just one of the speeds at which a mobile phone can connect to the Internet. Let me give you an example, 3G is like a highway, and palmistry is your tool for running on this road. It's not just a mobile phone like a tractor, eight horses, ten horses, even if you press the accelerator all the way, it's just that speed.

As for what it can do, it depends on what functions the mobile phone you buy, 3G cards can generally be installed on non-3G mobile phones, as 2G use. A 2G card can also be installed on a 3G mobile phone, or 2GThere is also a little note,What 3G number you use must depend on what kind of 3G network the mobile phone you bought?,Finally, I'll give you some personal advice,If you like the rich functions of the mobile phone,Mobile phone Internet access,Then choose 3G card 3G smart phone,After you install games,Software or something is good for expansion。 Let's not talk about non-smart phones. If you just want to buy a cheaper 3G mobile phone to experience it, forget it, it's useless, it's far from what you think, or what business hall, advertising, save a few hundred yuan to get a 3G mobile phone, 3G number or something, it's useless, that is, you spend a few hundred yuan to buy a mobile phone, sign a contract, pull you a customer, and dozens of monthly rents are enough for you to play **.

Nowadays smartphones are also cheap and have a lot of options.

Having said all that, I believe you have your own choice. If you don't understand, ask again.

It can be used, but it can't be used for 3G services.

1. Unicom's USIM card has 4G function, if you are using a USIM card, you can directly upgrade to 4G** if you meet the conditions; If you are using a SIM card, you need to go to the business hall to replace the USIM card before you can upgrade to 4G**.
