Ask HN: Suspicious SMS sent to my phone on my birthday

2 pointsgood-citizen2 comments

from some random # i don't know to my phone: "Happy Birthday! Sorry I'm not there to enjoy it with you, but we can grab a drink and some other fun goodies when I return"

must be spammers, knew my birthday was today, and are trying to trick me into replying?

Did not know your birthday, sent it to 1000s of people to confirm phone number if you replied so they could send you more spammy stuff later or sell info to spammers.

Or

Someone you know sent the message using some service that allows free SMS to be sent.
