DoorKing 1800-250 — the factory replacement SIM card for DoorKing's DKS Cellular boxes, supplied pre-configured to register with DoorKing's server (DoorKing's own description: "SIM IMServer Config"). It is the service part for the 1800-080 cellular voice and data box, the 1800-081 AccessPlus version and the 1801-080 voice-only box that replace the copper phone line on 1800-series telephone entry systems. Sold loose, one card.
Order this only when DoorKing tech support tells you to. A DKS Cellular box ships with its SIM installed and activated through DoorKing's online system on AT&T LTE; DoorKing does not publish a user SIM-swap procedure. Before ordering, call DoorKing at 800-826-7493 with the serial number of the box — they will confirm the card, and the box has to be re-registered on their server after the card goes in. We will not know more about your box than they do.

Common questions
What does the monthly plan cost?
DoorKing bills it directly: voice-plus-data plans from about $46 a month, voice-only from about $41, data-only from about $35 (DoorKing's 2026 schedule, before the autopay credit), plus a one-time $45 activation per box.
Can I use my own carrier SIM?
No. The boxes run on DoorKing's service only.
Is this the SIM for the 2112 eVolve?
No. The eVolve cellular kits (2112-150 / 151 / 152 / 153) carry their own SIM dongle.

Have the serial number of your cellular box ready and call DoorKing first; then, if you need the card, email parts@gatehousesupplies.com or call 866-965-5599. We would rather confirm it than have you order twice.
