Can anyone put me in a direction to get information on how I can send (protocol) text messages to mobile phones? Thanks
 
About the easiest way is to use ... a mobile phone. If you have a WAP/GPRS phone you can connect it to your PC (Bluetooth?) and use it as a modem.

There are AT code sequences to perform messaging documented on the Nokia website. Send the code sequences to your modem. Have a look at (The AT command set is not specific to the 8210)
 
Thanks for the info. There seem several options open, none as easy as I was hoping. I thought a mobile could have been communicated through a normal landline in some way however other directions seem to be through SMS websites/active server pages etc. Maybe your idea to use a mobile via bluetooth as a modem is the best solution, wish I was a bit more knowledgeable on AT commands. Thanks again.
 
Hello ZOR,

THe problem is this. Mobile phones are on an entirely different network. yes you can call them from a land line but then again you can call the internet from a land line.

The difference is the same. To connect from a computer to the internet you need a Modem. Modulator/Demodulator. To connect to a cellular network it is the same, you need a cellular modem.

As for what kind of Modem to use, well there are a lot of options, in North America, and Europe BlueTooth is pretty popular, it has hardware and software.

I just did a notification service to send SMS messages to mobile phones for a client in India. The system was very different. There I had to use a Nokia Premicell and then send it AT commands. Much like the above mentioned.

Basically what your going to have to do is this. Find what service provider you want to support. You have to pick 1 and 1 only. In most contries each company is pissy with the other and won't allow inter messaging between companies. Then you have to ask that company how you would access their network.

Some may even have a call in facility, Bell Canada does for Text Pagers, not sure of SMS though. No one here really uses SMS.

Happy hunting. Craig, mailto:sander@cogeco.ca

What's a 'cellular modem' when it's at home.

I've been looking into this myself. Look for SMS on componentsource. There are several extremely expensive solutions available. I assume the price has more to do with perceived value than how hard it is to do. It is easy to text from web sites for free, but I think they are doing that partly to collect mobile numbers and bombard same with adverts.

English situation is somewhat different. You can (I think) text to any phone irrespective of network.
And texting is wildly popular. Particularly with school age children. Over 1 billion were sent in a single month. Peter Meachem

I looked up 'cellular modem', and now I know what it is. Expensive business isn't it. Peter Meachem

Thanks for all the further info. I am looking around at mobile phones using bluetooth, that seems to be the most logical option open from what I can see. I also found some websites set up with servers you can go through, but then they can call the tunes. I need to try and figure out AT commands, I downloaded some info from Nokia following Norris's suggestion, good documents. I also downloaded a sites help file which was interesting as well. Thanks all
 
Small Hint: If you have a modem that only supports PDU mode (not Text), than you have to code your data into PDU format.

Peter,

You can access (SMS) mobile networks in UK using landline. You have to know the correct access number, and a standard analog modem will do it. What the protocol is I dont know.
I did have a program that was designed to act as a gateway between email server and SMS, written by a company in Sheffield I beleive, I'll try and find out more

Yes I know now. have a dll call sms messenger that works ok and an app called sms centre. Another way is to use something like Clickatell which is pretty cheap. I'm not quite certain about that method though. Looks like a good way to collect mobile numbers to me. Peter Meachem

mattKnight has it right about the UK. This is the way I used to do in in an old program of mine. I have a feeling I should still have the source code at home somewhere (with a breakdown of the protocol), and a list of numbers for various service providers.

Outside the UK, the number list is probably of not much use, but the protocol used to communicate with the message centres was supposed to be a 'standard' (just cannot remember it's name at the moment), which might be useful.
 
Oh - the name of the protocol has come back to me! It's called TAP

And here's a site with a list of phone numbers you can reach from an analogue modem that you can talk to with TAP-compliant software (this is the U-V page, since I happen to be interested in the UK)


and here's another:


And here's a link to the protocol:
