The Cradlepoint 170752-002 is an AT&T-branded UICC-I trio SIM card designed for use with Cradlepoint cellular routers and gateways. It ships in a single trio card that can be punched down to 2FF (mini), 3FF (micro), or 4FF (nano) form factor, letting field techs fit it to whatever tray size the target device uses without stocking three separate SIM sizes. The SIM is provisioned on AT&T's network and is built to support both 4G and 5G data service paths, depending on the plan and device capabilities. It is intended to be paired with a Cradlepoint router or gateway as part of an AT&T cellular data plan for that deployment. This is a carrier SIM only; it does not include a modem or radio of its own and must be inserted into a compatible cellular device to provide connectivity.
