An electrical assembly comprises a housing having a frame portion. A substrate has a first side and a second side opposite the first side. A subscriber identification module is mounted to a first side of the substrate and has device terminals. A first connector portion is secured to the second side of the substrate and has connector terminals. A retainer is associated with an interior of the frame portion. The retainer retains at least one of the substrate and the first connector portion. Conductive (e.g., conductive vias or through-holes) in the substrate connect the connector terminals to the device terminals.
