I do have T-Mobile. I do have unlimited text messages and I just have the blackberry unlimited add-on. I was sure to clarify this with customer service. If you look on their website, if you do JUST a blackberry plan with e-mail then it does not include text messages. If you have the addon then it does include it. Check the website out. Under "Plans" click on "blackberry plans" and you see the mins and mail plan. That does include text messages.
