Text is the same as a phone call... if it doesn't connect with you, then it never happened.
Actually this is incorrect. I just tested this and sent myself a text message from a blocked number.
Even though the text did not show on my phone, my balance went down by 10 cents
Also, I sent myself a text yesterday while my phone was turned off, and I logged into t-mobile.com and checked my balance, and my messages allowance went down too.
So no, you can't block spam texts AT ALL. A spammer can send you 100 texts, and as soon as they hit t-mobile servers, you will get deducted $10 even if your phone is turned off.

I have a prepaid plan, but I don't text or message. If I see who called, and I don't recognise the number I block it. I have never been charged.
