Phone access during quarantine is extremely limited. The quarantine period functions similarly to the SHU in terms of communication restrictions, meaning phone privileges are reduced to roughly one call per week rather than the standard schedule. Do not count on regular contact during those first two weeks.
There is also the orientation piece to consider. Even after quarantine ends, most facilities require inmates to complete an Admissions and Orientation process before full phone privileges are activated. If those two things overlap, it can push regular phone access out to two weeks or slightly beyond from the arrival date.
The best way to stay connected during this window is mail. Letters can reach an inmate even during quarantine and orientation, and a letter with your phone number clearly written in it gives them what they need to call you as soon as their access opens up. Send one now so it is in the pipeline.
