DIDs: (10-digit phone
numbers) are available for P2P (Person to Person) traffic only. Send and
receive text messages in a fluent 2-way manner. Each account license key
is assigned one or more DIDs for sending and receiving text messages.
CDYNE recommends sending no more than 500
messages per DID per day. All marketing, one-way and alert type
messaging requires the use of a short
SimpleSMSSend is recommended for sending
single, immediate text messages.
AdvancedSMSSend is recommended for sending
scheduled text messages and allows multiple numbers with one message, or
multiple numbers with individual messages.
U.S. Carriers are standardized and all text messages are 160 characters
(including spaces) in length. When sending a text message to a recipient
in the U.S. with more than 160 characters, the SMS Notify! API will
automatically split the message into two or more messages for delivery.
Canadian Carriers vary from 136 to 160 characters (including spaces) in
length. CDYNE sends to Canada the same way as the U.S. To ensure
complete message delivery, CDYNE advises that your application only send
messages to Canadian recipients in 136 character increments. If the
message is longer than 136 characters, the best practice is to split the
message on your application side at the 136 character mark to avoid data
loss that may occur from Canadian Carriers that truncate anything over
136 or 140 characters.
Your account DIDs determine which destinations may be reached.
By default, SMS Notify! will send text messages per domestic or
international assigned DIDs via round-robin. When you pass a license key
with multiple DIDs assigned, SMS Notify! will look for the country code
to determine which sending DIDs to use.
When CDYNE detects 1 + area code, we look for a U.S. DID. If a Canadian
area code is detected, SMS Notify! will look for a Canadian DID first.
If not available, it will look for a U.S. DID to send the text message.
When 011 + country code is detected, SMS Notify! will first look for the
local international DID (i.e. sending 011 + 61 will prompt SMS Notify!
to use an Australian DID). If not available, it will look for the
default U.K. DID for sending.
SMS Notify! will send messages to the U.S., Canada, or worldwide. The
turnaround time to obtain account DIDs vary by coverage and whether or
not you request an area code specific DID.

SMS Notify! recognizes the date and time in
(Coordinated Universal Time). When clocks move forward 1 hour in the
spring, most time zones will need to remove one hour from their UTC
offset. For example, Eastern Standard Time (EST) is UTC -5 hours but
Eastern Daylight Time (EDT) is UTC -4 hours.
