@Sven-Brandau said in Network time: Hello, is the feature ‘network time’ (3GPP 27.007 Ch. 8.15) for NB-IOT/Cat-M1 supported in the Deutsche Telekom mobile network? The NRF9160 SIP returns an error, while requesting the time. Also after a long time of being connected. Hi Sven, sorry that it took us so long. But now we have a clear statement from our experts that the network time feature is NOT supported in our network in Germany.

Hi, I did “normal” TCP/IP MQTT on top of NB-IoT connection with the Quectel BC66. So TCP/IP is possible. But I didn’t try to post a normal HTTP request. LWM2M is implemented on top of CoAP and UDP. By this it works perfectly on NB-IoT. It is also supported by Quectel BC66. We tested it successfully with Eclipse Leshan server and the Nokia Impact LWM2M server. Regards, Roland

Spain confirmed!

Problem solved. It denpends on the sim card

May I suggest you also take a look at our central FAQ page for NB-IoT Roaming?

Hi Thomas, sorry for late response. Please check our latest version of the Solution Guidelines, we have extended it with the information you inquired about. BR, Aleksandra

Hi Thomas, every module supplier implement their own Maximal Transfer Unit (MTU). They can reach up to 1.358 Bytes. If the message is larger than the MTU, the message should be divided into smaller messages. We only limit the amount of data per month and the number of daily messages per device. Best regards Noah

@apuhl , with a classic M2M GSIM (IMSI starting with 90140), you may use the standard APN “internet.m2mportal.de”, with a Consumer SIM card (starting with 26201), it should be “internet.telekom.de”. Best, Ronan

Hello Max, our network supports just one active PDP context per connection. Best regards

The PLMN of Telekom Deutschland is 26201
