So, I have had this problem with my Verizon Galaxy S5 since I inherited it from a friend. I am unable to send, or recieve any form of MMS. I think it may be due to the fact that GSM and CDMA are extremely different from each other. I need to know if there is a way to fix this.
I guess you are using it on T-Mobile from the title, so if it works for telephony and data the problem isn't with GSM vs CDMA. If those work then most likely your APN settings are the issue. Check these (in your mobile data settings) and compare with what they should be for your carrier. Some carriers use separate APNs for data and MMS, so you can have one work and not the other.

If it really were a GSM vs CDMA thing there would be nothing you could do but get another handset.
The only problem is that I don't see any other APN options than what I have entered repeatedly into my phone.
