Sprint
PCS
uses
IOTA
(IP
‐
based
Over
The
Air)
for
their
Over
‐
the
‐
Air
provisioning
system.
IOTA
uses
packet
data
calls
to
transfer
the
configuration
data
to
the
phone.
These
IOTA
data
sessions
can
be
network
initiated
or
client
initiated.
Network
initiated
IOTA
is
the
preferred
method.
An
automatic
network
initiated
IOTA
session
occurs
when
the
module
first
registers
onto
the
Sprint
network.
This
IOTA
session
is
queued
when
Sprint
originally
sets
up
and
'activates'
the
account.
In
their
current
implementation,
Sprint
imposes
a
72
hour
expiration
timer
for
this
queued
IOTA
session.
An
IOTA
session
has
a
device
time
‐
out
of
15
minutes.
If
there
is
no
success
within
15
minutes,
the
status
will
change
to
fail
and
the
module
will
stop
trying.
A
normal
IOTA
session
takes
from
1
to
3
minutes.
To
register
onto
the
network,
the
module
needs
a
sufficient
signal
and
must
be
manually
provisioned
with
the
MDN
and
MSID.
The
IOTA
session
will
occur
and
populate
the
3GPD
parameters.
If
it
is
the
first
IOTA
session,
it
is
called
a
Network
Initiated
Initial
Provisioning
(NIIP.)
NOTE:
An
IOTA
session
MUST
occur
while
the
device
has
a
sufficient
signal
and
is
registered
on
the
Sprint
PCS
Network.
A
session
will
not
be
successful
if
the
device
is
out
of
coverage
or
not
properly
registered
on
the
Sprint
PCS
network.

Wait
5
to
10
minutes
for
the
device
to
register
on
the
network.
Call
your

to
test
activation.
When
it

confirm
the
number
matches,
answer
and
