AT+CSCA? returns empty string with 6210?

[kesslerdesign]

at+csca?
+CSCA: "",129

OK

That's what I get with my 6210 (v5.27 and also previous sw) instead of the smscenter-number which can be read with 51xx, 61xx and others like that. Playing around with CRES helps nothing.

So how do I get the (default) smscenter via AT out of a 6210?

Does the phone contain the SC number in the message settings?
You can also set the SC number yourself: AT+CSCA="+3478987987",145.
Then you can try to save the setting with AT+CSAS=1. There can be
slight differences in how the AT-commands work in different
phonemodels.
