Employer Portal Access
Employer contacts who previously had access to the Vimly SIMON portal are being pre-registered for the new MagnaCare Employer Portal.
If you did not previously access the Vimly SIMON portal, please send an email to the Trust Office with your First Name, Last Name, email address and Employer Group name.
On Wednesday, September 2nd, designated employer portal users should look for an email invitation with instructions to access and activate their account. Once activated, the portal can be used to manage enrollment and eligibility.
