8 16 1 Where do I start?

Excuse me, did you get the message? If it is a short message, 8 16 1 is the SP code, and 8 1 is the Japanese country code. The query is very simple. If it is a short message, please call 100 10 or 10086 to find out which SP's short message code this is. If it's a phone number, I suggest you enter it directly.
