Hi,
To make it clearer. A GSM modem is a mobile phone as far as the operator is
concerned. Both are using a SIM card and are charged by it. Kannel doesn't
care. The differences between a GSM modem and a mobile phone (with modem
functionality) are:
1) You can use your mobile for other things as well (calling friends, etc.)
2) A dedicated GSM modem is more reliable, in terms of DLRs, status and SMS
handling.
BR,
Nikos

David,
Unfortunately you won't save any money this way....You will pay the same
price by sending an SMS from a mobile phone or using Kannel->gms modem. Well,
you save money because you can use Kannel instead of other commercial products.
Kannel only helps you in enabling SMS on your website/application.

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
