E18C-LTE SIM installation guide

Which SIM does the Akuvox E18C-LTE take?

A nano SIM (4FF) carrying data. The E18C is a 7-inch face-recognition access terminal with SIP intercom — everything it does over 4G (calls, cloud, face data sync) is data traffic. Voice-only SIMs need not apply.

Which network and allowance?

Strongest 4G data where the terminal mounts — speed-test there. A multi-network data SIM keeps it on the best carrier and rides out coverage changes, which matters on a device that's often the sole access point for a building.

Allowance: face-recognition terminals sync more than a simple door phone — video calls plus cloud traffic. Size up for month one, then right-size from real usage.

Fitting the SIM

For the installing engineer, power down:

1. Fit the nano SIM in the terminal's slot.
2. Power up and set the APN for your provider — nothing cloud-side works until it's right.
3. Enrol the device on the Akuvox platform, update firmware, then enrol users.

First test

Full access matrix before handover: face recognition unlock, PIN, card if used, and an intercom call landing on a phone with two-way audio and release.

If it won't connect

• No data: APN first, always.
• Cloud sync failing, data fine: allowance or platform subscription.
• Calls not landing on phones: app permissions and battery optimisation on the handsets.

FAQ

Does it need Ethernet? No — LTE carries it. Ethernet remains an option where it exists.

Voice or data SIM? Data.

Ongoing costs? The SIM plan plus the Akuvox cloud platform — quote both.
