Hi Alvaro, thanks for your help. I asked for the CGSMS conf in the modem and in fact it is 1, anyway I'll try your recommendation... the actual init string is: "AT+CMEE=1;+CNMI=1,2,0,1,0" , can you explain me a little about the setting 1?.
No problems with the SIM it's a postpaid bulk plan with no limitations. Yes, I tried to connect to the modem with minicom after the error but can't send any AT commands, looking to the modem's led (LS) indicates that it is connected to the network. Regards. -----Original Message----- From: Alvaro Cornejo [mailto:[email protected]] Sent: Wednesday, January 08, 2014 1:29 PM To: Vinicio Cruz Cc: users Subject: Re: Modem stops working after receiving an SMS while sending Hi Can you try to use AT+CGSMS=1 on the init string? Also, I assume your SIM is active and has enough funds. Have you tested in a minicom session sending manual commands? What about your modem loosing network registration? Try AT+CREG?. it should say something like CREG:1 Regards Alvaro |--------------------------------------------------------------------------- --------------------------------------| Envíe y Reciba Datos y mensajes de Texto (SMS) hacia y desde cualquier celular y Nextel en el Perú, México y en mas de 180 paises.
