I'd be tempted to use Google to see if any service providers will permit that.

Why can't you just upload the data to a web site, use a little script to insert it into a database and another script to display the data to the user? You could use the GET statement and include the parameters in the URL?

If you are using Serial1 you need to connect Mega pins 18 & 19 to pins 2 & 3 on the modem.

And you don't need two

Code:
Sim900Serial.begin()

You have connected the grounds together?

A link to the device might help.

If you have wired it up as per your illustration then

Code:
SoftwareSerial GTM(2, 3);

should be:

Code:
SoftwareSerial GTM(7, 8);

Go have a look at the link Rob gave you. Download and install his library (remove the others first). There is an example there for you to get an understanding of the syntax.

It works. I've been using it for some time now.
82  Using Arduino / Programming Questions / Re: RPM using hall effect sensor on: August 12, 2014, 04:42:56 pm
The way I would approach it, in very general terms, is to have your sensor connected to an interrupt pin to count the impulses. In the mean time your sketch will check the number of pulses received once a second, multiply that by 60 (pulses per minute) and that is your RPM.

On a motorbike with all the noise on the electrical circuit the sketch is probably going to be the least of your challenges.

This evening I tried jumpering the Uno from last night to a Seeed SIM900 shield but I was unable to get a signal lock, I'll try again tomorrow.

Do you get either of the two connection messages? "Not connected" or "Connected to GPRS network"?

I'm assuming that the phone companies allow you to use a mobile device as a web server? I think I might have heard something to the contrary some time ago.
84  Using Arduino / Networking, Protocols, and Devices / Re: Web Server example why is it not working for me? on: August 11, 2014, 03:28:27 pm
Right, brief update. I've tried the sketch on the official shield and it shouldn't come as any surprise that it seems to work. I get as far as getting an IP address which will do for me, it proves it's connected. But that's my lot for this evening. I'm using O2 PAYG, I believe GiffGaff use their network.

How far do you get?

The eBay listing and the 'wiki' page are for subtly different items. Which one have you got? Is the sim card holder on top or underneath?
86  Using Arduino / Programming Questions / Re: SIM900 programming problems, help needed on: August 11, 2014, 09:22:40 am
Which Arduino?

Which SIM900 shield? (Link please)
87  Using Arduino / Networking, Protocols, and Devices / Re: Web Server example why is it not working for me? on: August 11, 2014, 02:24:15 am
Hardly professional!

I've not come across that variant before, and looking at the schematic you can select either D0 & D1 or D2 & D3 for communication, which is probably why the SendSMS sketch works.
88  Using Arduino / Networking, Protocols, and Devices / Re: Web Server example why is it not working for me? on: August 09, 2014, 04:33:08 am
To be honest I have no idea why the examples would would for sending an SMS message.

The pin definitions are held in GSM3SoftSerial.cpp

Unfortunately I don't have a SIM900 based shield on hand this weekend to do any testing!

Could you post a link to the shield you have?
89  Using Arduino / Networking, Protocols, and Devices / Re: Web Server example why is it not working for me? on: August 08, 2014, 09:32:54 am
If you are using the examples provided with the IDE then they are for the official Arduino GSM/GPRS shield, and as distributed use pins 2 & 3 to communicate with the shield.

I don't know which shield you have but the inexpensive SIM900s use pins 7 & 8 (or 0 & 1)  to communicate.
90  Using Arduino / Programming Questions / Re: Error with code from Arduino starter KIT on: August 08, 2014, 08:53:36 am
Code:
  digitalRead(LED, HIGH);

That doesn't look right. Do you mean digitalWrite?
