GSM:
Spectrum Technologies recommends the purchase of a 3G
Pay As You Go SIM Card and Service Plan with voice and text ca-
pabilities. For example, a $25 Pay As You Go SIM card with a 90
day life
would work well.
Be sure to have the retailer properly test the SIM card to verify it
works before leaving the store.
IMPORTANT: If the SIM card is running low of funds, the Cellular
Alert might believe a call went through when it actually was inter-
cepted by the carrier to play a recording notifying you of low card
funds. Check for these messages regularly by testing the SIM card
in a cell phone.
CDMA:
Spectrum's CDMA Modems do not have a removable
‘
SIM
’
card and typically do not offer Pay As You Go plans. Consult with
your cellular provider to obtain a cost effective plan. A machine
-
to
-
machine plan with voice and text capabilities will work with modem
technology.
CDMA modems need to be
‘
provisioned
’
after a cellular plan is acti-
vated.
THE CDMA MODEM CANNOT COMPLETE A VOICE CALL
OR TEXT MESSAGE UNTIL THIS IS DONE. PLEASE SEE PAGE

—PROVISIONING CDMA MODEM.
Some carriers send a text message or voice call after the first call of
the day on prepaid accounts. This may cause the first call or calls to
fail as your carrier sends welcome texts and screen banners. If your
test call or text fails, please wait a minute and retry.
Be sure to test your Cellular Alert to ensure calls and/or texts are
successfully received before it is used in production.
