#1 Mobile Manager skips sms

[Darío]

Sometimes Mobile Manager can skip sms. I've been trying to isolate the problem, and I've taken this log from a skipped one (including pre and post polls). As you can see, a timeout occurred after Mobile Manager sent the request for unread messages (maybe the wait was too short?). Then, it can't recover the error but the message has already been marked as read by the modem, and it will last forever in the sim's memory for not being noticed nevermore. Sadly, it's happening quite too often:

PD1: The sms saved in the sim on the first poll was another skipped one, but I lost those logs. :-S
PD2: ¿Supongo que hablan español, verdad?
