Long time Sprint customer here. Recently switched to TMO, but still using mostly Sprint phones. Calling, SMS, LTE all work fine for the most part. MMS will not send or receive while on WiFi. I am wondering if anyone has any knowledge/experience using ##DATA# and the MSL code to change any data parameters to make that work? I've tried all kinds of things with the APN. Phones are S7 Edge (Android 7.0) and Note 5 (Android 6.01). Thanks
