Hello, first of all, thank you for your support to China Telecom. According to your description, this is not possible, there are not many telecom 4G mobile phones on the market at present, and a batch of telecom 4G mobile phones will be launched after the year, and your contract machine cannot be replaced with 4G mobile phones.

If you need to buy a mobile phone, you can log in to Guangdong Telecom mobile phone**, the lowest price of 100 brand mobile phones on the whole network. I hope I have been helpful to you, and if you have any questions, please feel free to continue to consult us.

If the user has signed a contract for the contract machine, the electrical signal card of the contract machine cannot be cancelled during the contract period, and only after the contract expires, it can be replaced with another telecom card. Thank you for your question, please log in to Telecom Broadband**.

The 3G network mode supported by the telecom customized iPhone 4S is CDMA2000, which does not support the use of China Unicom 3G (WCDMA) standard, and it is impossible to use China Unicom 3G network.

Dear users:

According to your description, the iphone4s telecom contract machine, after the contract time is up, it is not possible to change the 3G on the mobile or Unicom card, because the iphone4s telecom machine only supports the mobile phone card of the telecom, it is a CDMA mobile phone.

If you need to buy a machine, you can go to Anhui Telecom Tianyi store (hundreds of mobile phones are low on the whole network.

Hello, the general contract machine is to lock the operator network, it is recommended that you consult the telecom customer service to confirm whether you can put in the mobile number to use, and if you put the number of China Mobile in the iphone4s mobile phone, you can not use the China Mobile 3G network.

iPhone4S telecom contract machine, after the contract time is up, it is not possible to replace the 3G on the mobile or Unicom card, because the iPhone4S telecom contract machine is a special model, it only supports the 2G 3G network mode of Telecom.

It has nothing to do with the contract or anything, it is made in the CDMA system, and it can only be used with a telecom card.

OK.

You have to wait until the contract has passed.

By that time, 4s were also obsolete.

No, you can only use a telecom card, either CDMA or CDMA2000

That can only buy a Unicom contract machine, hehe, the domestic ** special, not three networks to eat.

Telecom three G network is different from other 2G networks, so the 2G card can not be used, but this supports Unicom 2G card, but Unicom 3G can not be used, I went to the business hall to ask, you can't use other cards to swipe, and it doesn't work, and Huawei flash, you have to wait at most three days to apply for an unlock code! : You can use a different telecom card. However, what needs to be informed here is that if you have a card on your contract machine, then it is not recommended that you use the card separately.

Because, the telecom will continue to charge the card of your contract machine according to the contract. Not very suitable for you. We hope you will consider.

There will be no locks or anything! Please rest assured!! I hope you are satisfied with the answer, and you can ask questions!

You can change it, but I'm afraid that the phone bill given to you in your card won't be given away.

If you can change the card, only Unicom can't change it.

The Apple 4 telecom contract machine can be exchanged for another telecom card if it does not expire, but it will affect the return of the phone bill.

1. Contract phone refers to the type of mobile phone customized by the communication operator and the mobile phone manufacturer, and the user must sign a contract with the designated operator to use the mobile phone, and must pay off the rental phone in a lump sum (most of them are paid in the name of the phone bill).

2. Generally speaking, the contract machine cannot be replaced, and the phone bill will not be refunded if the phone is locked after the card is replaced, and liquidated damages will be paid at worst.
