SMS Mod/Hack ?

[filth]

I very much doubt a free sms provider would allow you to do this or provide an api for you.

If you are willing to pay for the SMS messages then a service such as http://www.clickatell.com could easily be used (download their api and you will see how easy it is) of course there are many others as well.

As stated on my post in the vbhacks site for them to be able to reply you would need to have the 2 way facility (so when they reply the reply gets sent to a php script) the prices on clickatell do not state how much this costs but instead ask you to contact them to ask for details (presumably also to find out how many you estimate you will need)

Another problem is the maximum limit on characters allowed in an sms message what I said on vbhacks seems to be slightly inaccurate (I said 72 characters was the max) it is in fact

Max message parts exceeded *
The text message component of the message is greater than the permitted 160 characters (70 Unicode characters). Select Concat=1, 2, or 3 to overcome this by splitting the message across multiple messages.

basically if the max characters are exceeded then it splits them up into multiple messages (depending on how you have it set)

Values set are: concat=


Value Status
0 No concatenation - only 1 message
1 Concatenate of maximum of 1 message
2 Concatenate of maximum of 2 messages
3 Concatenate of maximum of 3 messages

the amount of characters is not changeable as I beleive they have chosen an amount that works with most networks.

REGARDING

For instance it sends the sms no. and message query to the site (logs in first if a login is required) waits for a response - if the response is postive - a message comes back saying it's been sent (this is the general idea).

this is easy enough it can be set to show when the message has been sent, when the network has received the message or when the message is received by the mobile.

it would be a very bad idea to have it set to have it hold on for a response as if there is a delay then the script would time out and I very much doubt a user would wait to see, for example if someone had their mobile turned off then you would not receive a message to say the mobile had received the message until the mobile was next turned on and if the user is anything like me I always forget to charge my phone and have it turned off for a couple of days at a time sometimes.
