How to change the mobile 4g card?

Although China Mobile officially launched the mobile 4G mobile phone in Beijing at the beginning of this month, the majority of users don't know how to change it, whether they need to change the package or not, and they can change any mobile phone. A few days ago, Ji Feng. Bian Xiao personally walked into the business hall of China Mobile Gongzhufen and experienced the whole process of changing cards.

In the business hall, the girl at the front desk came to ask and explained the purpose of coming. The author got the number sheet as scheduled and waited in line to accept the card replacement service. In the process of handling, the process is very simple. When it's the author's turn, the relevant staff only need to show the corresponding 4G mobile phone according to the mobile phone owner's ID card and the original SIM card, and they can replace the new 4G card for free.

After getting a new card, if the phone number is stored in the previous SIM card, the staff needs to reverse the data. If not, you can directly put the card into your mobile phone for normal use. In use, the author found that it is a bit troublesome to re-enter the PIN code every time a mobile phone card is inserted (the initial PIN code of Beijing Mobile's 4G card is 1234).

After the treatment, the author began to use it with great interest. However, due to the subway all the way to work, except for the occasional 4G signal from Jianguomen to Chaoyangmen, the subway line 1 from Gongzhufen to Jianguomen has only 2G and 3G networks, which does not hinder normal use, but the speed is slightly lower. However, in the location where there is a 4G network, the network speed performance is still very good, and the video browsing is relatively smooth, and the experimental results are still ideal.

In addition, in the business hall, the author also asked many questions about mobile 4G. Next, Bian Xiao answered several questions that netizens were concerned about.

Question 1: What are the requirements for replacing the 4G SIM card?

A: Users who want to replace the 4G SIM card only need to buy a 4G mobile phone device in the business hall or bring a 4G mobile phone with the 4G logo of China Mobile. With my ID card, I can apply for the original mobile phone SIM card for free.

Question 2: Which number segments can be replaced? Do I need to change my mobile phone number?

A: At present, all mobile phone numbers can handle 4G SIM cards, including GSM, China Mobile and M-Zone. To handle mobile 4G, users do not need to change their mobile phone numbers, only need to change a card.

Question 3: After replacing the 4G card, do you want to replace the original mobile phone package?

A: At present, replacing the mobile 4G mobile phone card will not affect the user's original package. No matter whether the user uses the contract machine purchased by the operator or the 4G mobile phone purchased by himself, the original package will still be maintained. However, it should be noted that due to the very fast network speed of 4G, users with small original traffic packages suggest buying large traffic packages directly from operators. Moreover, at present, anyone who buys a contract machine in an operator can get a certain amount of free traffic in the first month, which seems to be more humanized.

Question 4: Must the replaced 4G mobile phone card be used on 4G mobile phones?

A: Even if you have a mobile 4G SIM card, you don't have to use it on a mobile 4G phone. Other mobile phones that support GSM and TD-SCDMA networks can be used by users. Just above the network, there is no longer a mobile 4G network, only a mobile 2G or 3G network.

However, if you buy a 4G mobile phone through prepaid phone bills, you need to insert a mobile 4G SIM card, which will be used once a month for the first six months, and there will be no restrictions after six months.

Question 5: 5: What areas does the 4G network cover?

A: As of press time, Beijing's 4G network has temporarily covered the East, West and North Third Ring Roads, Guangdong and Guangxi Road in the south, Tsinghua, Peking University, Guo Mao, CBD and Garden Expo Park. However, according to the staff of the business hall, Beijing's 4G network construction is very fast, and new areas will increase the coverage of 4G networks every day. I believe that when 4G is officially put into operation, 4G networks can be used in most areas.

According to the author's personal experience after changing the card, it is found that some stations can receive 4G signals when taking the subway, but in most cases it is only 3G and 2G networks. I believe it will be improved with the increase of signal coverage in the future.

Question 6: Does the area without 4G network affect the normal use of 4G mobile phones?

A: According to the staff of China Mobile, although the signal coverage of 4G mobile phones is not comprehensive in the experience stage, it will not affect the normal use of users. When there is no 4G network, the 4G card can automatically switch to 2G and 3G networks, and the daily phone calls and short messages will not be affected, but the Internet speed will decrease.

Question 7: What contract machines are there now?

A: At present, Samsung NoteII(N7 108D), Sony M35T, Coolpad 8736 and Huawei G7 16 can be handled in the mobile business hall, and users can get 4G mobile phones by pre-storing phone bills.

Different models of 4G mobile phones have different prices, so users can choose products suitable for their monthly consumption according to their own conditions. At present, there is no corresponding package for 4G mobile phones to choose from. As long as users reach the minimum consumption limit agreed by you and the operator, they can make phone calls, send text messages or buy internet traffic packages, which is much more flexible than the traditional package plan.

Question 8: Can I get a 4G mobile phone for free?

A: There is no pie that can't be dropped. Any old users of China Mobile who are 10 years old and over 10 years old can get their mobile phones free of charge by pre-storing their phone bills. Compared with other users, old users over 10 can apply for 4G packages for free in the business hall, and do not need to pay the prepaid phone bill, but they must also reach the minimum consumption limit every month.

Question 9: Besides contract machines, what other 4G mobile phones are there?

A: In addition to the four 4G mobile phones currently displayed in China Mobile Business Hall, five devices including HTC One Max, ZTE Memo LTE, Tianyu Hornet 4G, Hisense X6T and Huawei D2 also support China Mobile's 4G network. If you want to know more.

Question 10: which business halls in Beijing can handle it?

A: According to the past practice, China Mobile has also restricted the card exchange business hall for 4G SIM cards. At present, only ten business halls, such as Huimeida Customer Service Hall, Xizhimen Business Hall, Caishikou Business Hall, Wangfujing Business Hall, Wangjing Business Hall, Gongzhufen Business Hall, Financial Street Business Hall, Zhongguancun West Business Hall, Sanyuanqiao Business Hall and Chaowai Business Hall, can handle it.

Question 1 1: Can the Hong Kong version of the iPhone5s move 4G?

A: Although the online version of the iPhone5s can support mobile 4G, it has also been verified. However, the staff of China Mobile Business Office did not give a positive answer. The staff just said that at present, the SIM card of mobile 4G can be replaced by the Hong Kong version of iPhone5s, but it may not be able to use the 4G network, and even the original 2G network cannot be used, which has brought trouble to users. Whether to replace it or not is still up to the user to decide.

Except for the Hong Kong version of 5s, some international versions of 4G mobile phones may not be compatible with China Mobile's 4G network. Users are advised to temporarily use the mobile phone with the 4G logo of China Mobile.

Question12: What is the network speed of 4G?

A: Although the staff in the business hall said that the 4G network in the signal stable area can reach 100M/s, according to the previous test results of Jifeng. Com, the highest network speed in the international trade area is 30.25Mbps per second, which is still far from the official expectation. If you want to know more about it.

Question 13: Will there be any problems after replacing the 4G SIM card?

Answer: There is no difference between normal use of 4G cards and ordinary cards. However, every time you insert a 4G card, you need to re-enter the PIN code when you restart it, which brings some inconvenience to users who frequently change their mobile phones.

Editor's comment: Generally speaking, it is not troublesome to replace the 4G mobile phone card. Just go to the business hall to handle it. However, from the author's actual experience, it is strongly recommended that you test whether you can connect to 4G, 3G and 2G networks on site, so as not to cause trouble to normal use. In addition, for users who don't have many mobile phone traffic packages and often surf the Internet, they may wish to apply for large-capacity traffic packages directly in the business hall to prevent the traffic packages from exceeding the limit.

At present, the 4G network is still in the experience stage, and there is still a long way to go before it is officially commercialized. If you are not in a hurry to use a faster mobile phone network, you may wish to wait until the 4G network is officially commercialized before handling related business. I believe there will be more 4G mobile phones for you to choose from, and related tariff packages will also be introduced, which is estimated to be much better than now.
