The JAGER PRO I.C.E.™ Cellular Cam sends scouting and intelligence photos to your cell phone or e-mail when the PIR motion sensor detects movement. This cellular camera supports MMS, SMS and e-mail via any GSM Network carrier such as AT&T or T-mobile. All you need is an activated SIM card and a 32 GB or smaller SD card. An AT&T SIM card with unlimited texting ($25.00 or $15.00 per month) purchased directly from AT&T is all users need to communicate with the I.C.E.™ Camera. You can set up a pay by month plan with AT&T for $25.00 per month. Or if you have an AT&T phone plan, you can add a line for $15.00 per month.
