Hi Cezary,
Thank you ever so much for the useful info.
The basic point that I still can really understand is 'how' Kannel - or any
free gateway - could reduce the cost of sending sms. I just need to get the
answer before going through installing linux, buyinga GSM modem, etc.
Despite googling a lot for the last 10 days, I am still 'confused' really.
The aim is to set it up for someone abroad. The sim card provider do not allow
sending free messages from a mobile phone.
So, if we went for the option:
Application -> Free Gateway (e.g. Kannel) -> GSM modem ( + simcard)
How could that be cheaper than to send them directly from a mobile phone?
On Kannel's website, one of the answers for this question
1.2 Why should I use Kannel instead of a commercial WAP gateway?
is: The price is right :-) Do you really want to pay thousands of dollars of a
WAP gateway?
May be in this particular case, one should go for the other option, to bypass
the sim card provider altogether, i.e.:-
Application -> Free Gateway (e.g. Kannel) -> SMSc agent/provider
In any case, thank you once again for your reply.
Best regards,
David

I think 1000sms/day is too much for gsm modem/sim card.
I'm assuming you are UK based. Most of UK networks don't allow to send more
than 3k sms/month (even if you are on 'unlimited text' plan). If you exceed
that volume you may be disconnected or charged as per normal text 10-15p.
Please check T and C (especially the "fair usage policy") of your SIM provider
before you decide to go this way.
If you get an SMPP connection from SMS carrier you will pay 3-5p/sms.
AFAIK:
H3G UK - allows to send 3k SMS. After that you will be charged 10p
t-mibile UK - "If you send more than 3000 texts a month or text more than 200
different numbers in 5 days, you may be breaking your terms and conditions,
which say that you can’t use your phone for anything unlawful or to send
nuisance"
O2 UK- "All usage must be for your private, personal and non-commercial
purposes. You may not use your SIM Card: a. in, or connected to, any other
device including modems;"
Best Regards,
Cezary

Hi Nikos,
Many thanks for your repsonse. It is really useful.
Before actually sending my enquiry to this list, I had done some searchig for a
while on google, and I understood that the only way to send sms message to
recepints is by going through an SMS Centre for the dsetination network.
In your reply, you mentioned as an option:
Application -> Kannel -> GSM modem
Can it really be done that way - *bypassing* the SMS centre?
And if yes, what is considered as "low volume"? Would 1000 messages per day
be 'OK' with a sim card provider?
And of course, it all depends on the destination network. Real SS7
connections may not be an option.
I would appreciate your advice.
Best regards
David

Hi,
1) To push SMS you will need:
Application -> Kannel -> GSM modem
-or-
Application -> Kannel -> SMSc link
Application is some kind of web interface to facilitate and schedule pushes.
Optionally you can substitute one of kannel's components, smsbox, with SQLbox
for sending bulk.
GSM modem provides for a low volume, cheaper usually interface using a SIM
card. But volume is restricted else SIM maybe disabled. SMSc provides for a
more reliable interface, however, throughput is restricted according to your
contract. Volume is unlimited (of course you are charged for each SMS). You can
also shop around to get the lowest price globally, whereas with a SIM you are
restricted by what your operator gives you.
2) Cost depends on your volume and destination. If Clickatell is an
aggeragator, ie routes SMS to other SMScs, you can do better than them. If,
however, they have real SS7 connections, given their volume, it is unlikely.
BR,
Nikos

Hello,
I have windows xp on my pc, and am very interested in Kannel.
Before installing Linux and going through the whole process, I would like to
know, if possible, please:-
1. To send sms messages, what else would one need apart from:-
Kannel + GSM modem + SMSC connectivity (for recepients' network)
Anything else apart from the above 3 'components'?
2. Would that arrangement be actually cheaper than to go through some bulk SMS
suppliers like Clickatell, for example? I think it should, but I am not sure.
I would greatly appreciate an answer.
Best regards,
David
