So my boyfriend doesn't have texting and uses yahoo to send ims directly to my phone. we've been doing this for awhile and have never had a problem. but today, i recieved a text and continued receiving it every half a second for about 8.5 hours. it takes breaks from time to time. it's stopped now. but when it's really going, there's not enough of a break to even dial a phone call. is it possible to block this number without having to sign up for this whole plan smartlimits plan? SOMEONE PLEASE HELP ME tech support closed before i could call and i'm getting desperate and my phone is now just straight up vibrating - there's not even a gap between the texts. i don't know what to do.
