Application and functions

You require a SIM card of your mobile wireless provider.
Recommendations
Note the following recommendations for the mobile wireless contract or for the SIM card:
● Where possible sign a mobile wireless contract with a provider that makes all required
functions available. Should
For example to use DynDNS a public IP address is required.
To send SMS messages, the SIM card must be enabled this function and have a phone
number.
● Avoid using a multi SIM card. This can lead to errors in time-of-day synchronization.
● Where possible sign a fixed mobile wireless contract and do not use prepaid cards.
A flat rate for SMS and data can be recommended.
If, however, you want to use a prepaid card note the following:
– If your credit has been used up, the CMR does not send an automatic warning.
– You can query your current credit with your provider.
● With the CMR2040 for faster data traffic a contract (with corresponding SIM card) is
recommended that supports the mobile wireless standard LTE.
The CMR2040 however also supports UMTS.
● Where possible, use a standard SIM card without an adapter.
● The provider often assigns a PIN (Personal Identification Number) for the SIM card.
SIM cards that are only used for the data services (see above) can be almost always
used without a PIN. You do not need to assign a PIN in the configuration of the CMR.
● The following access data for the mobile wireless network must be present:
– Access Point Name (APN)
– Depending on the service provider also name and password for the APN
– The authentication method
