My internet phone service can no longer send texts to MTS Cell phones, but it works fine for other cell phone services.

Hey Tim,

I've sent a request into our network operations centre so we can check and see if any blocks or error message have been recorded in our system. We may have to open a ticket to begin an investigation if the problem is not something our technicians cannot solve themselves, as is often the case with inter-carrier issues. I will follow up and expect to have have an answer within a day.

Matt
