Why am I not able to view notifications sometimes?

How to get MMS working on the BlackBerry Z30?

I am currently using Straighttalk on a BlackBerry Z30 Unlocked STA100-5 OS 10.2.1.3442 bought directly from RIM with a Straighttalk card bought directly from them.

Can't understand why it seems the only solutions are found for the Z10, etc.. My APN is tfdata but it asks for a username and password that I don't have. If I get that info and add the port:80 will it work? I hear tell about someone using escreens (I'm clueless about that) and seeing videos of it, that is MMS, working but no DIY how-to?

Forgive me if this is a double post but it will definitely help others that have a Z30 and not just assume it doesn't work because the fix everyone shows says Z10.

Normally you don't have to enter username and password. Do you have the correct apn settings?
