I m getting a lot of unsolicited sms texts in my cellphone,how did all these ppl get my cellphone number?

I think someone is playing games with you. One person can send an sms and have many different names yet be from one sending orgin. Through yahoo, you can create a new screen name- unlimited, then text a sms using your number. Theres also gmail sms, and your original phone provider problobly has sms on their website. Many ways to sms you, from just one person. Therefore, your just gonna have to keep ignoring those msgs until the sending party falls asleep or goes to the bathroom, eats, or finds another number. Sorry, I know its a bother. Good luck.
