Thanks for the assistance in getting the SMS out and in working again. I am now seeing the MMS messages not being sent - again they are sitting on the outbound Q, there appears to be no attempt to send them. I enclose the INI file and the logs for reference.

Hi Neil, Unfortunately, I don't have any good advice for you this time. This appears to be revisiting earlier issues that you experienced with MMS. The problem is that the GPRS data connection is failing. It works sometimes (not very often), while other times it fails. This usually points to a problem with signal strength problem for the modem. For troubleshooting help, NowSMS sends an AT+CSQ command to the modem at startup, the response back indicates the signal strength. This should be reported in the SMSDEBUG.LOG. I'd be curious what this command reports. (I'd have to look it up to refresh my memory on what a good value is.) The "RAS Error 718" is a PPP timeout, which basically means that the data connection is failing. (The other nonsense in the error description comes from us asking Windows for more information about the error.) In other cases, the PPP connection is established, but we are unable to make a TCP/IP connection to the operator proxy over this connection. Both of these issues suggest signal strength problems. I'd expect that you would experience similar problems if you tried to use that modem for internet access. As I don't have any experience with the modem that you're using, I'd also be inclined that you try a different modem.

Hi Neil, A CSQ value of 18 should be ok. It's not great, but it should be sufficient. That said, different modems may behave differently, reporting signal strength differently, and behaving differently with different levels of signal strength. In my home office, I usually get a value of 10-12, and about 50% of my MMS connections fail. (Better than what you seem to be seeing.) I don't see any problems with SMS. By contrast, in the office, I get a value in the mid-20s, and don't have any problems using the same modem that has a 50% failure rate at home. This 718 error is coming from Windows dial-up networking, so essentially you should see the same type of problems if you try connecting using the modem as an dial-up internet connection from Windows. I've done some further web searching on this error, and signal strength is the most common culprit. I'd do whatever you can to position that modem to get a higher CSQ value in the first position. A few longshot ideas ... The dial-up networking profile could be corrupted. Try deleting any dial-up networking profiles in Windows that start with "NowSMS -". They will be automatically recreated on the next connection attempt. Try editing SMSGW.INI, and under the section header for your modem, add CommandPostInit1=AT+CGATT=1 (This tells the modem to perform a low-level attach to GPRS at startup. Most modems do this by default, but maybe yours does not. Even if it does not, it will still attempt a GPRS attach before activating a data session ... but maybe doing this during modem init will improve success.) You could also try editing the modem driver under Phone & Modem Options in the Windows Control Panel, and lowering the maximum port speed. (If this makes no difference or makes it worse, go back and change the setting back to avoid future conversion.) I should stress that these suggestions are "longshots". Improving signal strength is the more likely solution. -- Des NowSMS Support | ||||||

I've spent too long trying to get the current configuration to work, and am now considering equipment failure as a possibility. What would your recommended modem for the UK market (we have a vodafone account) be? | ||||||

I like the Option modems and have an ICON 322 that I always travel with. As we periodically buy modems for testing, we always try to get them unlocked. I bought the ICON 322 that I travel with on Amazon. I've also bought some other modems through Expansys. Currently Amazon UK has a good price on the ICON 225. -- Des NowSMS Support | ||||||

ok I have got an option Icon 515. Sending SMS fine - setting up MMS fails. This is on orange. The Orange software connects fine to 3G comms (there is no download for the 515 yet on the website). I also have a Huawei 160 for testign purposes | ||||||

I have checked with Orange, account was not set for MMS. This has now been enabled, I'll check when I have confirmation that this has been actioned. | ||||||

Ok account has been set up for MMS, I have received the confirmation SMS to this fact. From the diagnostic lights I can see that the modem does make a GPRS connection, but fails to talk to the Wap gateway. What logs would assist in diagnosis? | ||||||

Did you get it locked to Orange with a data SIM? When you buy a modem with a data SIM, the SIM is typically provisioned to allow internet access. It is typically provisioned for SMS access, but often not for MMS. This is one of the reasons I recommend unlocked modems. Move a SIM from a phone that can successfully send/receive MMS into a modem. So my first suggestion would be to make sure that whatever SIM you are using in the modem can send/receive MMS messages OK in a phone. Then put the SIM in the modem. For Orange, you can also try the following as an alternate WAP gateway address: http://192.168.224.10:8080 But first step, I'd make sure that whatever SIM you are using can send/receive MMS messages in a phone. If it can't, you might be able to get the operator to provision it for MMS access ... but this tends to confuse mobile operators. They understand that you can send/receive SMS using a modem, but they don't think it is possible to send/receive MMS, so you can't find anyone at the operator that will provision it for you. -- Des NowSMS Support | ||||||

I now have it working. I had already got the account enabled for MMS. I tracked the issue down to the firewall blocking the comms. It was able to establish the GPRS connection - but not then able to connect to the gateway. Thanks for your help. It is pretty hard work explaining to Network support how you can send MMS over a dongle, but we got there eventually. | ||||||
