Baoji Unicom SMS can't be sent as long as there are words such as credit card.

I'm sure I can send it. I tried it with my Unicom number, and there was no problem. Check the SMS settings of your mobile phone or the sensitive word settings of SMS security software. It may be that security software blocks the words "credit card" and "bank card" by default in order to prevent users from being cheated.

If you can't find a place to modify the settings, you can try to write it like this: the letters are marked with *-and separated by punctuation marks.
