10.2. The 2nd Way:
Sending SMS Messages from a Computer through a Connection to the SMSC
or SMS Gateway of a Wireless Carrier or SMS Service Provider
The
way for sending SMS messages from a computer through a mobile phone
or GSM/GPRS modem has a major limitation, that is the SMS sending
rate is too low. If you need a high SMS sending rate, obtaining a
direct connection to the SMS center (SMSC) or SMS gateway of a
wireless carrier is necessary. The connection may be made through the
Internet, X.25 or dial-up. If you cannot get a direct connection to
the SMSC or SMS gateway of a wireless carrier, another choice is to
get a connection to the SMS gateway of an SMS service provider, which
will forward SMS messages towards a suitable SMSC.
10.2.1. Difficulties
in Getting a Direct Connection to the SMSC or SMS Gateway of a
Wireless Carrier
It
can be difficult for small businesses or individual application
developers to obtain a direct connection to the SMSC or SMS gateway
of a wireless carrier since a wireless carrier may only provide such
service to those who have huge SMS traffic. Buying SMS messages in
bulk means the total fee will be very high (although the fee per SMS
message will be low).
Besides,
the information about the service (for example, cost of the service,
protocols supported, network coverage) is usually not stated clearly
on a wireless carrier's web site. This is because the wireless
carrier staff wants to know more about your SMS messaging
application, such as its nature and traffic requirement, before
offering a price and providing further information to you. To decide
which wireless carrier's service plan is the best, you have to
discuss with the sales staff of each wireless carriers. This is
troublesome if you just want to send a small number of SMS messages.
(Of course if you need to send a large amount of SMS messages, say
one million SMS messages per month, negotiating with the wireless
carrier staff for a more favorable agreement is a necessary step.)
A
more convenient way to send SMS messages is to use the SMS
connectivity service of an SMS service provider, which is described
in the next section.
