Updated Optima digital panel with GSM option.
Digital entry phone panel | Re-sourced 2026-08-10 against the ELFON Optima functional-modules catalogue (karta katalogowa, p.3, "Modul przekierowan Optima Smart GSM1"): "Gniazdo kart SIM: nanoSIM (2G) Orange Polska, Plus, T-Mobile Polska". The panel itself is a 2-wire intercom; the SIM sits in the optional OP-S-GSM1 module, which is 2G-ONLY and takes a nanoSIM. Previous sim_form_factor "Standard (2FF)" was wrong and has been corrected to Nano (4FF). Panel manual Tabela 1 (p.6) marks every Optima model TAK for Optima SMART, so GSM is a factory-supported option rather than an aftermarket bolt-on. CAUTION for UK use: module is 2G-only and the datasheet lists Polish operators only.
