PULS(afterthedeviceshaveconnectedtothenetworkandsentintheirfirstIDReport).SeethePULSUsers
Guideformoreinformation.
IfyoudohappentohaveaSIM,theoperatorwillaskfortheIMSIandICCID(IntegratedCircuitCard
Identifier)alongwiththeIMEIoftheLMU.Again,inreturnyoushouldgetalistofIMSIsandPhone
Numbers.
TheIMEI,IMSIandICCIDareallavailablethroughtheATI1command.TheIMEIshouldalsobeprintedon
thebottomoftheLMU.
YoushouldalsogetanAPN(AccessPointName)value.TheAPNisthedeviceonthenetworkthatallowsa
GPRSdevice(i.e.theLMU)togettotheinternet.TheytendtolooklikeaURL,forexample:
myAPN.myOperator.com
OperatorscanoffermorethanonetypeofAPNandcanevensetupacustomAPNjustforyourdevices.The
ratestheychargewillvarydependingontheAPNserviceyouwant.Operatorsmayalsorequestyouusea
blankAPN.WiththeAPN,youshouldalsoreceiveausernameandpasswordcombination.
ThelastitemanoperatormayprovideisaSIMPIN.ThePINiseffectivelyapasswordtothedevice.Themain
differencehereisthatthePINwillrestrictallthecapabilitiesoftheGSMdevice,wheretheSPCisusedjust
forconfiguration.
TheactivationsequenceforaGSMLMUwouldthereforelookasfollows:
AT$APPPARAM2306,0,“myAPN.myOperator.com”
AT$APPPARAM2306,1,“myAPN.myOperator.com”
AT$APPPARAM2314,0,“myUSername”
AT$APPPARAM2315,0,“myPassword”
ForablankAPNthefollowingcommandcanbeused:
AT$APPPARAM2306,0,“”(forablankAPN)
OnlyenterthisnextcommandifyouhavebeengivenanonzeroPINasanyerrorsmaylockyououtofthe
modem.
AT$APPPIN<SIMpin>
YoucanconfirmactivationbywatchingtheCommLEDtoseeifitgoessolid.Youmayalsoconfirm
activationusing
AT$APPCOMMSTATUS?
Agoodresponseshouldlooksimilartothefollowing:
