Telit Cinterion LE910C4: APN and network setup with an IoT SIM

Updated 27 October 2026

The Telit Cinterion LE910C4 is a cellular module for LTE Cat-4 with 3G and 2G fallback; it also has GNSS. With an IoT SIM, you set the APN, then check that the module is registered, at home or in roaming. The commands below are the standard ones of 3GPP TS 27.007. Telit Cinterion's AT command reference guides require a customer login; vendor commands for context activation and technology selection are documented there.

Key facts

Telit Cinterion describes it as	LTE Cat 4 member of the LE910Cx series (LTE Cat 1/4)
Radio technologies	LTE Cat-4, 3G, 2G
2G fallback	yes
3G fallback	yes
GNSS	yes
Form factor	LGA (xE910 family), 28.2 × 28.2 × 2.2 mm; LE910C4-WWX: 29.4 × 29.4 × 2.2 mm
Variants and regions	LE910Cx series. Linux: -EU, -NF/-NFD, India variant. ThreadX: -EUX, -WWX, -SNX, -NFX

2G and 3G fallback depend on the variant: the LE910C4-EU lists both, the -NF 3G only, the India variant 2G only, and the -SNX and -NFX neither (Telit LE910Cx Linux and ThreadX pages).

Set the APN

The standard 3GPP command defines the APN of PDP context 1:

AT+CGDCONT=1,"IP","<apn>"

Source: 3GPP TS 27.007. Check Telit Cinterion's AT command manual for the context number this module uses.

Replace <apn> with the APN shown in your M2M.global account: the internet APN, or your private APN.

Check that it works

AT+CPIN?        SIM ready? expect +CPIN: READY
AT+CEREG?       LTE registration: stat 1 = home network, 5 = roaming
AT+COPS?        network the module is using
AT+CGDCONT?     APN actually configured

An IoT SIM that works in many countries is often registered in roaming: +CEREG: 0,5 is a valid, working registration. Firmware that waits only for status 1 (home network) never goes online on such a SIM. Status values come from 3GPP TS 27.007.

Networks and shutdowns

2G fallback helps only where 2G still runs. Many operators have switched it off: see the 2G and 3G shutdown dates.
Private delivery works with any module: the privacy is in the network path, not in the device. See private delivery.

The SIM: IoT SIM cards and IoT eSIM. All commands explained: AT commands.

Frequently asked questions

Does the Telit Cinterion LE910C4 fall back to 2G?

Yes, Telit Cinterion lists 2G (GSM/GPRS/EGPRS) fallback for the LE910C4. It only helps where operators still run 2G.

Why does my LE910C4 show +CEREG: 0,5?

Status 5 means registered in roaming, a normal working state for an IoT SIM that uses partner networks. Treat it like status 1 (home network) in your firmware.
