Hello, somehow I want to put the phone back into operation in my SL 230 BJ 03. Also my contribution to the topic SAP module. Since 200 -300 euros for a test is something much I tried another solution. If I put a T Mobile SIM into the standard Nokia phone everything goes. So I got a prepaid card from Tchibo. With that the Nokia gets no connection to the provider. Is there a solution for this problem? Here the Nokia seems for other providers g T Mobile has no prepaid cards. Therefore Tchibo. That would be an easy way to use the phone and the hands-free device. On longer distances I would simply redirect my normal mobile phone and everything would be fine.
