I have exactly the same problem as "leoking3". Manny users think that MMS is anyway useless and too expensive (me too), but this problem is bigger than it seems.
After I send a MMS the connection does not disconnect completely (on todayscreen connectionsymbol still active but ther is no active connection anymore (you can check this in the connectionmanager). I guess the problem is the inbuilt connection manager who has problems to switch between the MMS-modem connection and the GPRS-modem connection. Pressing the red button for 3 sec. and the connection icon switch back.
But sometimes silently the radio part hang up too. This is not visible for the user because on the display everything seems OK (GPRS icon + Networksignal icon show good connection) . You only realice when you want to dial out, or somewone tries to phone you or if you want to connect to the internet (then you get the errormassage: unable to connect, check connectionsettings).
This happens not only during sending or receiving MMS, but also sometimes when you change your location and book in to a new network cell.
I first thought that its a radioproblem, so I updated to 1.04, but still not working well. The problem is that this is not happening all the time and you can not realice when your phone silently stucks.
Maybe this happens to much more ALPINE users than we guess. But maybe they do not realice the problem. Because when somebody tells them that they where not reachable by mobilephone, they may think that this was because of bad network signal when they are on the road.
GPRS connection, Send/receive SMS + Email and sending MMS - always possible (except somtemes when radio part unvisibly hang up)
But MMS receiving - ony the first time possible after doing a hardreset. When I disconnect the networkconnection or wait for a while the display lights up for 1 sec. immediatly after I sent myself a test MMS but nothing else happens. But I found out that the radio part is tying to receive something (invisible), because I can hear through the loudspeakers of my Desktop- PC the typical noise when a phone connects to a GPRS network during the reciving process. The MMS never arrives in the postbox. I asked my servicprovider to check. They said that their server realiced the MMS transfer and got a feedback that the massage was sent/received correctly.
I think it is not a question about wrong settings. On my Hermes these settings work well. On the Alpine it works, but only once. Also my servicprovider confirmed that. (Allthough I tryed manny different settings too).
Its also not a problem of other external programms.
I tested (not only once) with a complete clean system (Hardreset and not installing any cabīs in the ext. rom except the MMS-cab and no external programms) without afford.
Made Hardreset, and let the system install the complete ext. rom automaticaly, did not install any other software and tested for two days too. Same result.
Tryed with 3 different SIM cards - same result
Removed STK (Simtoolkit programm) from autostart / Softreset - same result
I updated radio to vers. 1.04 - same result
I did not try to change the ROM jet, but i am afraid that this has no sense because other users have the same problem with different ROMīs too.
Iīm so curious about the reason, Is it a hardwarebroblem?
Pleeeeees Heeeelp !!!!!!!
P.S.: To fred92150: Your problem seems to be a different one. When servicprovider sent you a sms means that the sms was not able to submit the MMS. Maybe you use wrong Port (usualy use 9201)
