GPS Tracking

I have a GPS tracking app on my Smartphone, but when I get an email, message or call it stops working and I have to switch it back on.
I can ‘live track’ it on a PC and it shows my speed, location etc.

Is there a good ‘standalone’ equivalent for less than fifty notes? Something I can put in my bag and forget about it for at least 30 days but be able to track said bag online in real time?
Looked at scambay and very confused.
Anybody got or used one?

Yorky, is your phone Android? If so, get Google Latitude, if it already isn’t installed on your phone, or Google Maps. I had no idea what Google Latitude was until I discovered that, once enabled, it keeps track of where you’ve been and even gives a summary of your time away and shows patterns of travel that can be replayed for any day. It’s dead accurate. What’s more, it’s free. Hope that helps!
