 ==== USSD Codes ====
-Up to now, I did not manage to get my mobile contracts balance by USSD codes via AT commands ... (like you do with your phone by dialing *100#)
+I struggled getting USSD codes to work. Searching in the web yielded some reports, that upgrading the linux system did help. And ... well .. switching to an old laptop with a quite recent version of //Linux MINT// did help ...
+Command (this time on //minicom//) to get my balance is:
+  AT+CUSD=1,"*100#",15
+The immediate response was an ''OK'', but a few moments later, I got something like
+  +CUSD: 0,"<a lot of characters>",72
+While neither //gammu//((which showed something in HEX in the logs)) nor //ModemManager// showed any results to USSD Code submission, [[https://github.com/JochenHoch2/gsm-ussd|gsm-ussd]] did the Trick.
