Cel-Fi CONNECT Signal Booster I ordered it from stc, the signal booster that bypasses insulators. To be honest, the mobile SIM card must be stc. I bought it for 2300 and something. And I bought a long cable with it, extended to 15 meters. And I also bought the adapter. The stickers that come to stick the device to the window can only be bought from Amazon. For sale for 1900 final price with the cable and adapter.
