8. International
SMS Messages
Inter-operator
SMS messages can be further divided into two categories -- local
inter-operator SMS messages and international inter-operator SMS
messages (international SMS messages). A local inter-operator SMS
message is an SMS message that is sent from one wireless network
operator to another wireless network operator in the same country,
while an international SMS message is an SMS message that is sent
from a wireless network operator in one country to a wireless network
operator in another country.
Usually
the cost for sending an international SMS message from a mobile phone
is higher than that for sending a local inter-operator SMS message.
Hence, the cost for sending an intra-operator SMS message <= the
cost for sending a local inter-operator SMS message <= the cost
for sending an international SMS message.
The
interoperability of SMS messaging between two wireless networks
locally and even internationally is undoubtedly a main factor that
contributes to the success of SMS worldwide.
