Hi, I'm trying to send MMS via my providers MMSC from the nowSMS interface (initial GSM setup MMS slider test function), however it seems I can never establish a PPP connection to the provider. I have setup APN, MMSC and proxy to working settings. This happens with multiple providers in North America on multiple different modems. This is setup on a raspberry pi4 using either Simcom7600g-h, Simcom7600na-h or Quectel ec25. I have tested multiple different sims and they work on mobile device to send MMS. I am able to send SMS from interface and directly with AT commands. If I try and connect to PPP via AT commands I am able to connect without issue. When I look at the debug log I can see it establishes the PPP connection fine ( CONNECT 150000000 ) and modem sends and receives, but at some point it says user terminated and closes connection without sending MMS. ( 21:37:22:689 [-1269844992] m=39,0 ppp_status_cb: Connection lost ) 21:37:48:713 [-1268792320] m=38,0 ProcessAdminRequest: ERROR - Unable to establish PPP data connection via APN 21:37:48:713 [-1268792320] m=39,0 ProcessAdminRequest: Status=ERROR - Unable to establish PPP data connection via APN See logs attached.
As well attached is connection setup from nowsms interface, when this fails the alert says "Unable to establish PPP data connection via APN" same as log. Any ideas on why this might be such a struggle to connect to service provider? Thanks. | ||||

Hi, I'm trying to send a test MMS from the nowsms interface. The testing area i'm using is the configuration for GSM modem. The slider for "send mms" is what i am testing to try and send MMS. The settings and sims's i am testing work on mobile devices to send MMS. when I check the logs i see PPP connection works, then disconnects. In the dashboard i just see alert that says "PPP connection to APN failed" ERROR - Unable to establish PPP data connection via APN I am using either a simcom7600g-h, Quectel ec25a or simcom7600n-a and they all send same alert and error log. attached here is the log.
When i run a PPP connection from AT commands i get "CONNECT 1500000" as well when i run 4g connection using QMLI im also able to connect to network provider as well. Any advice or guidance much appreciated. Thanks. | ||||

Edit SMSGW.INI and under the [SMSGW] header add: DebugPPP=Yes Try connecting again. The raw PPP packets should also be logged. There do appear to be some PPP packets being received, so maybe we will be able to see a problem. Regards, Bryce Norwood NowSMS Support |
