1) When you make a call are you using VOIP on 4G? (The 4G symbol will remain on.) Or do you swap to 3G? I suspect you may well drop to 3G - which could explain why your SMS go when your phone is "forced" to 3G (IIRC calls are not possible on 4G itself, only via 4G data as VOIP)
2) Do you have MMS parameters setup (Chats, preferences)? Normally shouldn't make any difference to SMS but if the other party has a crapple they have a habit of sending texts as MMS rather than SMS (at least folks I know do) and so a response goes as MMS unless I am careful.
When making a call I am using sim card carrier signal not VOIP. My sim usually defaults to 3G all the time but on occasion when booting phone up it will initially indicate 4G and then change after a few minutes to 3G. I have checked out Chatty and preferences and MMSC carrier settings states http://mms.invalid and APN states apn.invalid .... is this what you were talking about before? I have never touched these settings before.
