If you manually dial the number with a phone and hear a buzzing noise rather 
than modem negotiation tones (beep and whistles) the SIM is configured to 
accept incoming digital (UDI) calls only - contact the SIM supplier.  

 

8.3  I get Errors when using the TC35T with Storage Modules 

Please see Appendix D for advice if using the TC35T to communicate with storage 
modules connected to the datalogger.
