Dear Bryce, Just starting out configuring your NowMMSGateway v5. Please see attached screenshot:  When clicked on the Test Connection button, it could dial-up GPRS connection on T68i, established connection, "please be patient" message appeared..., and then failed. What should I do next? Question: Can T68i be used as GPRS modem for sending and receiving MMS? If not, would you recommend a GPRS modem? NE | |||

Nick, Did the error message say "Connection failed", or did it say "Unable to connect to WAP Gateway"? If it said "Unable to connect to WAP gateway", then remove the leading zero from the second and fourth parts of the IP address. That is, change the WAP gateway IP to 202.75.133.49, as there is a bug in the current release where NowSMS gets confused by leading zeros in a WAP gateway IP address. If the message says "Connection failed", go ahead and make the above change, but it won't fix the problem. This error means that we were unable to make the GPRS connection. I've tried this before on a T68i, and when NowSMS makes this attempt, the phone displays a dialog that says "Connecting" while it tries to make the GPRS connection. Do you see this?
No. So far I haven't seen any phones that can support "receive MMS" through the GSM modem interface. The MMS client in the phone always gets in the way. So it takes a dedicated GSM modem device. The Siemens MC35 is a good external GSM/GPRS modem ... and the Sierra Wireless Aircard 750 is a good PC card variation. -bn | |||

Dear Bryce, I definitely want to be able to receive MMS, more than sending it. I'll return to this installation as soon as I bought the modem. Wondering if you can reset my trial period until then? NE | |||

When the time comes, send me an e-mail (nowsms@now.co.uk) ... and remind me about this disucssion. | |||

OK. You can disable my current downloaded copy as I will not be using it until getting the modem. NE | |||

Hi Bryce, Is Wavecom Fastrack 1206 (or 1203) GSM/GPRS modem compatible with NowMMSGateway v5? NE | |||

Nick, To be completely honest, we are unsure about the level of GPRS support in Wavecom modems. Wavecom might have some new models available, but we have several customers try using Wavecom modems claiming to support GPRS, only to find out that if GPRS was supported, it was not supported through the standard interface defined in ETSI GSM 07.07. From a NowSMS perspective, our use of GPRS is very limited. We expect the GPRS connection to either function as a network driver, or we expect to be able to initate a GPRS connection via AT commands ... where we expect to use the AT+CGDCONT command to set the GPRS APN, and we expect to be able to initiate a GPRS connection by dialing *99#. (Both of which are defined in the ETSI GSM 07.07 specification.) All this said, looking at the spec sheet for the Wavecom Fastrack M1206, it certainly looks like it should work. I believe others were having problems with the M1203 which did not seem to support the GPRS commands. The spec sheet for the M1206 certainly implies that these commands should be supported, while I recall the old spec sheet for the M1203 did not have much information on GPRS. So, while I haven't had any feedback yet on the M1206, it certainly looks like the problems of past Wavecom GSM/GPRS modems may be resolved. -bn | |||

Thanks Bryce, for the detail reply. A question on GPRS class: Is the GPRS connection speed ultimately limited by the modem or operator? For example, if a modem is classified as Class 12 (eg. Sierra AirCard series), will the operator supports the maximum upload speed (4 slots [32-48kbps]), assuming the telco coverage is excellent at the particular location? I doubt it; how is your experience with various operators? And how about supporting configurable uplink/downlink slots on the fly? I feel that this should be taking care of automatically by GPRS protocol. NE | |||

Nick, I haven't had any experience in actually determining how many slots are actually being used at a given point in time. This would be useful to see real-time, but I have never bothered to check to see if Sierra's Watcher displays this stat or not. I have managed to see about a 30K download rate the few times that I have had to download a large amount of information over GPRS. So that tells me that I have at least 3 down slots. The overall connection speed is ultimately limited by both the modem and the operator. Coverage is one issue, but also an issue is how busy the operator network is at that location. The number of uplink/downlink slots allocated should be adjusted on the fly. -bn | |||
