visible sim card appears working when installed but only for a few minutes? Then it will be disconnected. Anyone figured out how to get visible sim to work? Or it is not possible for visible. I’ve tried T-mobile sim with no issue at all but never been able to get visible to work reliably. Thanks!
May you please provide the necessary logs, so we can check what's the issue? 
After upgrading firmware from e750-4.0 to e750-4.8.4_beta2, Visible (physical) sim card has been working without disconnection so far.
