T-Mobile has four features, the first being “Block All Chargeable Messages” and like the features name says it block all Chargeable Messages. The secound blocks chargeable IM messages, the third chargeable text messages and the fourt chargeable MMS messages.

Since T-Mobile offered very little information about these features on their website, many including my self thought that feature 3 - 4 would block messages after your 400th text/mms or 1000th text/mms.

But I quickly learned that was not the case when I could not send or recieve text and mms messages. In fact T-Mobile CS told me that those features override any plan you are in and block all Messages regardless of the plan you are in. So essentially I was told, if I enable those features I can’t send txt or receive them even though I am subscribing to a plan.

Today a T-Mobile spokesmen told me the following “T-Mobile has for years offered extensive filters built into the network to help detect and block spam text messages being sent to customer’s handsets that originate from internet IP addresses. These filters are updated on an ongoing basis, including monitoring for newly emerging schemes.

As a company committed to providing the best customer experience in wireless, T-Mobile also offers postpaid and FlexPay customers the ability to block chargeable text messages, MMS, IM and e-mail from being sent to their handsets at no additional charge. Customers can contact Customer Care or a retail sales representative for assistance and soon will be able to help themselves with tools on http://www.myt-mobile.com.”

So essentially they are spam filters, but then the T-Mobile spokesmen goes on to say Postpaid and FlexPay customers will have the ability to block chargeable text messages. So I am confused and will ask T-Mobile to clarify.
