Why can’t I set the SMS center number? It always prompts failure.

I just solved this problem. First, you need to download a software called "go SMS" and set the local center number "+8613******500" in the advanced settings of the software (if you don't know, you can search online or call directly to ask, + cannot be omitted) . Secondly, you enter the dialing interface, enter *#*#4636#*#*, then enter "Mobile Information", pull down the screen, there is a blank box for SMSC

You enter the local center number "+8613** ****500" (if you don't know, you can search online or call directly) fill in the empty box again, don't leave out the "+"; then, be sure not to make a mistake in the next step, press "Update" first button, and then press the "Refresh" button. At this time, regardless of the Shenma content in the refreshed box, even if it is "error

refresh", there is no problem. Don't move, the screen will freeze here. , shut down directly. After restarting, you will find that sending text messages using GO SMS

is

ok!! I hope it is useful to you~
