Hello,

I've a weird issue. I don't know what's going on...

I try to send SMS with a T-mobile SIM card in Germany. The SIM card 
doesn't require PIN code. I can get the GSM network and I don't use GPRS.

Sometimes, I can send SMS, and another time, It fails. More precisely, 
when I've got an ofono which can send SMS, I can send all the SMS I 
want, it works. But if I restart ofono, either it works or not.

I added OFONO_AT_DEBUG=1 in my env, and tried to find some troubles in 
the logs. I've got some errors but I don't think they are criticals and
anyway, they appeared when SMS working too :

-------------------------------
 > AT+CPINR\r
< \r\nERROR\r\n
Querying remaining pin retries failed

[...]

Provisioning failed
-------------------------------

I can see some differences in time for "AT+CRSM" commands but, they are 
in the same order. And, after many tests, I don't think the problem is here.

And, when the SMS send fails, the modem tells me :

-------------------------------
CMS ERROR: Unknown error\r\n

-------------------------------

Not very useful....

Also,@same time, I tested in Switzerland with SwissCom and I don't 
have problem.

1 month ago, it worked well. I don't get it...

I've got a "SIMCOM_SIM5216E" modem. Using the driver g1 or the new 
simcom driver I developped, with ofono 1.6 or 1.12, it's the same behavior.

Maybe have you already see this kind of things ? My brain is lost.

Regards,
avd.
