How to change the card for 4G self-service?

Preparation for 4G self-service card replacement: The special card for 4G self-service card replacement is only applicable to the old users who already have the telephone number of Telecom Tianyi. Please insert this 4G card into Tianyi 4G mobile phone, and insert the original UIM card into Tianyi 3G mobile phone, while keeping it turned on.

The operation steps of 4G self-service card replacement are as follows:

1. Send a short message "HK mobile phone number" to 10659 157 with a 4G mobile phone to obtain the verification code for card replacement (note: the mobile phone number is the original user's mobile phone number);

2. Check the verification code on the original 3G mobile phone, send "YZ verification code" to 10659 157 with the 3G mobile phone, and wait for the message of card replacement success;

3. After receiving the message of successful card replacement, restart the 4G mobile phone, and the original UIM card will be invalid;

4. After the card replacement is successful, the system will automatically check whether the user meets the conditions for opening the 4G function. If the conditions are met, the system will automatically turn on the 4G function. For users who do not meet the opening conditions, they will send "You have not opened the 4G Internet service, so you can send 4GSJ30 to 1000 1 to open the 4G upgrade traffic package, and you can enjoy the 4G extremely fast network after opening it".

Note: Huawei P7 and Mate7 listed terminals temporarily do not support self-service card replacement due to chip software version problems, which may lead to card replacement failure. After 20 14 12 1, the new P7 and Mate7 mobile phones shipped by Huawei support self-service card replacement.
