The transfer from Broward County to South Florida Reception Center is a short geographic move but it is still a full transition between two separate systems with their own intake processes. Give it a few days before expecting communication to resume.
Here is what is typically happening on his end right now. When an inmate arrives at a reception center they go through a processing and orientation period that includes medical screening, classification interviews, property inventory, and housing assignment. Phone access and commissary privileges generally do not become available until that intake process is complete and he has been assigned to a permanent housing unit within the facility. For most Florida DOC reception centers that window runs about one week from arrival, sometimes a few days faster if intake moves smoothly.
On the PIN and commissary account, Florida DOC uses a separate system from Broward County Jail. His account does not automatically transfer. You will need to set up a new account through whatever platform South Florida Reception Center uses for deposits, which is typically JPay for Florida state facilities. Go to jpay.com, search for South Florida Reception Center, and set up an account using his Florida DC number. That number is assigned by the Florida Department of Corrections and should have been given to him at sentencing or during the transfer paperwork.
If you do not yet have his DC number, it can be found through the Florida DOC offender search at dc.state.fl.us. Once you have it, the deposit process is straightforward and funds typically post within one to two business days.
In the meantime, sending a letter through InmateAid is the most reliable way to get a message to him during this gap before phone access is restored.
