What is CTA certification?

    The State implements a network access permit system for telecommunications terminal equipment, radio communication equipment, and telecommunications equipment involved in inter-network interchanges that are used to access public telecommunications networks. Telecommunications equipment must obtain a network access license; if it does not obtain a network access license, it must not be used in public telecommunications networks and sold in China.

Telecom equipment network access certificate

    In the network access license, the state implements a network access permit system for telecommunications terminal equipment, radio communication equipment and telecommunications equipment involved in accessing the public telecommunication network. The telecommunications equipment that implements the network access license system must obtain the network access license issued by the Ministry of Information Industry; if it does not obtain the network access license, it shall not access the public telecommunications network and use it for domestic sales. The network access license certificate includes the certificate number, the application unit, the manufacturer, the device name, the device model, the place of origin, the remarks, the date of issue of the certificate, and the limited date of the certificate. Network access licenses are generally valid for 3 years.

Precautions

    If there are special characters or patterns in the appearance of the model and the screen of the switch, please confirm with the test and certification department in advance whether it is allowed to use;

    After the sample has been sent, you need to change the appearance of the phone (including characters, graphics, buttons, etc.), you need to re-sample;

    If you need to change the model of the device after the sample has been sent, you need to re-send the sample.

    Non-mobile custom mobile phones, appearance silk screen and opening and closing interface are not allowed to appear "MO, CHIAN MOBILE" and other related words and LOGO.

    To access the network with a mobile customized mobile phone, you must obtain a short-term agreement with China Mobile to apply.

    Access to the network and related accessories must be prepared in advance.

    The photo of the prototype should be absolutely clear, especially the pattern, the text, and the close-up photo should not be used clearly; the photo should be comprehensive: including the front and back sides, the two sides, the front and back of the push and pull, the front of the flip, the upper and lower ends of the text Also, after opening the back shell to remove the battery, take a photo; the ratio of the photo to the prototype is greater than 1:1.

    The English description should be explained directly with the photo. That is to say, the photo is printed separately, and the meaning of the English and the pattern is directly marked on the photo (which can be black and white), and finally the non-other company logo is generally indicated.
