Maximum number of messages per day
is there an overview of the Cat.NB1 and Cat.M1 tariffs offered by DTAG, showing the maximum number of messages/day and the maximum number of bytes/message allowed depending on the selected tariff?
Reason for this question:
On page 3 of the Telekom „IoT Solution Guidelines 2.1 - No Harm to Network“ (see attached) I found this sentence:
IoT Server Applications communicating with IoT Devices over 3GPP Low Power Wide Area (LPWA) access bearers, such as NB-IoT and LTE-M, SHALL optimize their application reporting period to never exceed Deutsche Telekom affiliate tariff’s daily maximum number of messages."
I am aware of the limitation regarding the permitted data volume/month (500kByte/month/measuring point in the NB1 network).

For NB-IoT, DT recommends not exceeding more than 120 messages per day per device. Use cases requiring more frequent data transmissions would definitely be seen as out of the scope of what NB-IoT has been designed for.
An overview of the maximum values for NB-IoT and LTE-M isn’t available yet, but will be appended to the associated IoT offerings.
thanks for your response!
And what about the maximum length (number of bytes) per message?
Best regards, Thomas
Unfortunately we cannot answer this question at the moment. Please be patient, as we need to discuss the topic with our network experts.
are there any news concerning the maximum length (number of bytes) per message for NB-IoT and LTE-M?
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.
