The Concox GT06F protocol

The protocol of Concox's GT06F and GT300 — today Jimi IoT — a variant of the GT06 family with enough differences that <strong>they are not registered the same way</strong>.

Like the original GT06 it is binary and configured by text message. The GT300 is one you see on assets and motorcycles.

Which port it comes in onOur server listens for the Concox GT06F protocol on port 7023. That is the port you set on the device, together with the server address. Point it somewhere else and the data still leaves, but the server cannot read it.
Careful with what other sites tell youHere is the expensive mistake: picking plain «GT06» when the device is a GT06F. It powers up, gets signal and <strong>never reports</strong>, and you spend hours checking the SIM. If you have the IMEI, the IMEI tool tells you the exact variant.

Build the configuration command

Back to the lookup

IMEI lookupDevice identification tool. We do not perform unlocking, carrier release or mobile blacklist checks, and we are not affiliated with the GSMA.

Where the data comes fromPublic mobile TAC database (MIT licence, Copyright (c) 2026 Moaz Ebrahem), TAC codes published by Teltonika on its official wiki, and the protocol observed on devices connected to the Appogio platform. We publish no full IMEI and no customer data.

Frequently asked questions

Is the GT06F the same as the GT06?

No. It is a variant with enough differences that they are not registered the same way. Picking plain «GT06» for a GT06F is the expensive mistake: the device powers up and never reports.

How do I know which variant I have?

From the IMEI. Type it into the tool and we tell you the exact variant, without opening the device.

And the GT300?

It speaks this same variant. You see it mostly on assets and motorcycles.
