Mobile phone signal setting method

1. On the dial-up panel, enter * #4636 #*#*

2. Choose test> mobile phone information]

3. Pull down to find the preferred network type

Description

 

WCDMA preferred: wcmda is preferred, and China Unicom 3G network is preferred

GSM only: only GSM, only China Mobile and China Unicom 2G networks

WCDMA only: only wcmd first, only China Unicom 3G network

GSM auto (prolactin): Automatically selected by GSM. (Prolactin does not understand)

CDMA auto (prolactin): built-in selection of CDMA

CDMA only: only CDMA, only telecommunications network

I will not elaborate on it later. I will do it myself.
