Lumia 928 sms issue on Tmobile H and H+ networks.

Hi I bought a Lumia 928 twice in the year 2014. I was having weird sms and mms issues on Tmobile H+ and H networks with both the devices. Now in 2015 has anything changed with any new update. Will the Lumia 928 work on Tmobile without any sms issues on H network with the latest denim update. Please let me if there are anyone facing the sms issues onTmobile. I really would love to get it. Thanks,
