@inka-O internet.telekom is for smartphones. it won’t work for NB-IoT and the SIM cards are not allowed to use it I believe.

Hi all,

Please note that network time is now also provided over our LTE-M network in Germany, and can be retrieved with the usual AT commands (e.g. AT+CCLK?, AT+QLTS=2, …)

Best regards,

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.

The GSMA offers a “Mobile IoT Deployment Map”. You can click on a country and see various information per technology type e.g. which operator deployed that network type and even URL’s of the operators’ maps for that country (if the MNO made it available). GSMA is improving and enhancing it continuously.

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.

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 command for the US is:
AT+CGDCONT=1,“IP”, “iot.nb”

The PLMN of Telekom Deutschland is 26201

In Germany we have rolled out Band 8.
