Can the mobile phone card return to 4G after upgrading to 5G? Why?

If you want to go back to 4G after upgrading your mobile phone card to 5G, there are two situations, one can and the other cannot. 5G** cannot be downgraded to 4G**If the mobile phone card is directly changed from 4G** to 5G**, and the free traffic and **tariff have changed, then it is more difficult to return to 4G**. Because the operator's ** generally has a contract period, 5G** is two years for some and one year for some years.

During the contract period, you can usually only upgrade up, that is, you can choose the more expensive 5G, and you can't go back to the cheaper 4G. Take Telecom's 199 yuan 5G** as an example, the tariff description page of the ** clearly mentions that the tariff is valid for 2 years, and if both parties have no objection, the contract will be automatically renewed for 2 years. In other words, if you apply for this 5G**, you can't downgrade to a cheaper 4G** within 2 years, and you can only upgrade to a more expensive 5G** online.

If you don't want to use this after 2 years, you may have to explain to Telecom in advance to ask for savings, otherwise the renewal will be another 2 years.

Although this ** provision of the operator is somewhat impersonal, the operator tariff contract is also a kind of contract, which is protected by law and must be complied with by both parties once signed. Therefore, if you are a user who has handled this kind of 5G**, it is basically impossible to convert to 4G**. Unless the 4G you want to transfer is more expensive than the 5G you use now, but this kind of ** is theoretically none.

The 5G traffic package can be canceled, and the other situation is that your**is still 4G**, but it is upgraded to 5G** in the form of the operator's 5G traffic package. Some of this kind of traffic packages are paid on a monthly basis, and they are ordered once a month, if you don't want to use a 5G traffic package, you can cancel it in the same month, and you won't be deducted the next month.

This 5G data package is mainly customized for some users who are unwilling to upgrade to official 5G**. Because some users use the "speed limit" ** of 4G card, the network will not be disconnected after the traffic is exceeded, but only the speed will be limited. However, if you upgrade to the official 5G**, the function of "reaching the speed limit" will be gone, and you will be charged separately after the traffic is exceeded, which is not cost-effective.

Therefore, many 4G** users are reluctant to upgrade to 5G**, in order to attract this part of the user, operators have launched this 5G traffic package. For an extra 19 or 49 yuan per month, you can buy 10GB or 20GB of additional data, and turn the 4G traffic in ** into 5G traffic. This allows the use of 5G networks without changing 4G**.

Since this 5G traffic package is not a new tariff**, there is no contract constraint, so if you want to go back to 4G**, you only need to send a text message to cancel the 5G traffic package. For some users who don't want to upgrade to 5G**, this 5G data package is obviously more convenient, but the disadvantage is that the tariff is a bit more expensive than the official 5G**.

So if the 5G card wants to go back to the 4G card, the key depends on what kind of ** yours are, if it is an official 5G**, it can't be reduced to 4G. If the 5G traffic package becomes a 5G card, then the 4G card can be changed by canceling the 5G traffic package.

Able to go back to 4G. After the mobile phone card is upgraded to 5G, it can only be connected to 5G without changing the original function of the mobile phone card. So it is also possible to tune back to the 4G channel.

No, because the mobile phone card can only be upgraded positively, and when you reach 5G, you can't go back to 4G.

I think it shouldn't be able to, because 5G cards and 4G cards are completely different.

Transition from 4G to 5G, mobile phones, SIM cards.

All require network support, and network speed.

The faster, the better our experience, and as we all know, 2019 is called the "first year of 5G", at the beginning of the year, China Telecom.

He gave the first 5G** card to Pan Shiyi, the founder of SOHO China.

In that case, the transition from 4G to 5G, do you need to change your mobile phone and SIM card? China Mobile finally responded.

In the transition from 3G to 4G era, we changed the SIM card, so according to normal logic, since it is in the 5G era, the SIM card must also be replaced, but in fact, the role of the SIM card is equivalent to a "key", for example, if your WeChat, Alipay is updated, do you need to reset the password to set the password? Obviously, this is not a necessary thing. The so-called 5G** card is actually just a means of China Telecom's propaganda.

According to the author's information, the first 5G** card launched by China Telecom is still the 133 segment, that is to say, since the mobile phone number segment has not changed, it is no different from the 4G mobile phone card, the only difference may be that it has handled the 5G traffic **Lu suspicion. The response given by China Mobile is that this is a 4G transition to 5G, and users can upgrade for free, that is, there is no need to change the SIM card, and they can use the 5G network directly for the early model hand 5G**.

Finish. And we don't necessarily need to replace the 5G mobile phone, with the help of the 5G router, we can also convert the 5G network signal into a general WiFi signal, so that even if we don't change the mobile phone, we can also experience the 5G network speed. And, Lenovo has also launched a 5G laptop.

Therefore, the 5G era will indeed usher in a change, but no matter what, now buying 5G mobile phones and 5G computers is completely anxious to eat hot tofu, and the gains outweigh the losses.

As long as you are a 4G mobile phone card, you need to upgrade, if you feel that the network speed is slow, you can bring your own personal search card, and go to the Shouhuai business hall to change a mobile phone card.

4G mobile phone to 5G mobile phone ** card needs to replace 5G mobile phone ** card, 5G ** card chip and 4G ** card are different.

First of all, the current 5G mobile phone supports 4G card, so users can use it directly, and the current 4G can also directly use 5G traffic, but it needs to go to the area covered by the 5G network to act Sakura, but the network speed will be different from the user who directly uses the 5G card, because the ** card with the core of the Fan's Conghu itself is still a 4G card.

Hello, 4G mobile phone for 5G mobile phone can be upgraded to 5G**, old users of Telecom at the same grade to transfer 5G**, no other fees will be charged if there is no first service with a supplementary card. At present, China Telecom's 5G** starts from 129 yuan, divided into 7 levels, and the traffic reaches up to 300GB. Compared with 4G in the same gear**, 5G** contains more traffic resources, the unit price of traffic is more favorable, and provides 5G network, services, services, members and other state rights and interests.

Users can choose the right 5G** according to their actual needs. Policies vary from region to region, please refer to the actual situation.

Hello! According to your question description, the answer is as follows: There are several ways to upgrade a 4G mobile phone card to a 5G mobile phone card:

1.Replace a 5G SIM card - this is the most straightforward and easy way. You can contact your SIM card operator, purchase a new SIM card that supports the 5G network, and then insert a new 5G card into your phone to use the 5G network.

This method requires an additional 5G card fee, which may vary depending on carrier and card item. 2.Free Upgrades - Some operators offer free upgrades from 4G to 5G after users meet certain conditions (such as renewal conditions).

You need to contact your carrier's customer service to find out if you are qualified to enjoy this policy, and if you are eligible, you can directly apply for a free upgrade to use the 5G network. This is the most cost-effective method, but the eligibility and time window for applying for a merger may be limited. 3.

Self-service upgrade (supported by some models) - The latest models usually already have built-in functions or modules that support 5G networks, and can be used by simply turning on the 5G network switch. Some models support not only 4G but also 5G dual mode, and users can switch between the two modes at any time in the settings. As long as your model supports 5G, you can upgrade to a 5G network by directly turning on the 5G function switch.

However, these features are not supported on all models, so it is recommended to check the model description to confirm the specific support status. 4.Carrier Borrowing - Some operators offer 5G trial cards or 5G paid monthly cards, which users can borrow or purchase temporarily.

If you only need to use the 5G network for a short period of time, borrowing a 5G card from an operator is an option. However, this method is more suitable for short-term use, not a long-term replacement for 4G cards. To sum up, the main ways to upgrade the 5G network with a 4G mobile phone card are to replace the 5G card, the operator's free upgrade policy, turn on the built-in 5G function of the mobile phone, and borrow the operator's 5G card.

Choosing the right approach requires consideration of cost, support constraints, and usage needs. Please consult again if you have any other questions.

Summary. At present, 4G cards can be upgraded to 5G directly without changing cards, but you need to open 5G services, apply for 5G**, and purchase mobile phones that support 5G network standards. The 5G network in some provinces and cities is being tested, and it may not be open for the time being, you can contact the customer service of the mobile phone operator for consultation, and if there is already a local 5G network, you can change it directly**.

First of all, if you want to upgrade the mobile phone to 5G, then the baseband in the mobile phone must meet the requirements of being able to support 5G, that is to say, the mobile phone will be installed to meet the needs of the signal processor that can support the operation of 5G mobile phones, and then convert the information that can be received through this processor to be sent, up to now, companies like Huawei, Qualcomm and other companies are developing this chip.

Secondly, mobile phones need operators to provide the corresponding network to be able to use, but until now the 5G network has not really become popular, the three major operators are also in the experimental stage, and have not officially built 5G network lines, so only when the 5G base station is really built, can it be really used.

"Hello and welcome to China Telecom. To be able to use the 5G network, your mobile phone needs to support the 5G network standard and the 5G network signal has been opened in the area, and the user installs the mobile phone card and turns on the 5G network function of the mobile phone, then you can use the 5G network.

Telecom 4G users can upgrade to 5G** through the following ways:

1. You can log in to the Shanghai Telecom online business hall - 5G area to handle the 5G upgrade, 2. You can pay attention to the telecom WeChat***, such as China Telecom Shanghai network hall WeChat***, click the quick query menu bar - turn on 5G life to handle the 5G upgrade.

4. You can go to the offline business hall of Telecom to handle the 5G upgrade.

If the old user transfers to 5G** at the same level, there is no other fee for those who do not have an additional card, and those with an additional card need to be charged for the additional card. "

The mobile phone card is upgraded to 5G, and the mobile phone is 4G, of course, this cannot use the 5G network. If the mobile phone does not support 5G, it is impossible to connect to the 5G network, so you can only change to a 5G mobile phone.

No, it is indeed necessary to upgrade the 3G mobile phone card to 4G like before, but now you want to upgrade to a 5G mobile phone card, you don't need to change the card, the business hall will directly help you upgrade for free, and the mobile phone number will not change, but **the**will change, and now 5G**** is still relatively expensive, so if you are not in a hurry to upgrade,There is no need to upgrade for the time being, because the 4G network can basically meet the needs in life.

Maybe everyone knows by nowThe 4G network of mobile phones has begun to be popularized in an all-round way, and many of the new mobile phones released by Huawei have 5G functions, and 5G is still much faster than 4GHowever, many users are still curious, if they want to experience the speed of the 5G networkThen you have to buy a mobile phone that supports 5G, so do you have to change your mobile phone card, after all, you have to replace the SIM card from a 3G card to a 4G card,Its Zen configuration is realized in the upgrade from 4G card to 5G does not need to change the card,Each business hall will directly upgrade you for free5G network,But the corresponding traffic **** will be changed。

However, your ** number will not change,What was your previous number and it's still this number.,But I personally think that if everyone's demand is enough now,There's no need to upgrade to 5G first.After all, at present, the cost of 5G is still a bit expensive, and the speed of 4G can basically meet everyone's needs now, and mobile phones equipped with 5G are often more high-end models, almost all of them are more than 5,000, and ordinary users are rarely willing to spend money to buy, so it is said that 5G will continue to popularize coverage in a few years, and it is not too late to upgrade when the time comes.
