Is it possible for a 'standard' GPS enabled phone to be tracked without an expensive subscription service?
I was going to stash an old PAYG mobile phone into a horsebox we have, hardwiring it to a 12v power supply so it was always on. If the trailer was stolen, I could pay a few quid and track it via the mobile phone transmitters/triangulation, accuracy can be as low as 200-300 metres but it gives you an idea of where to look.
I've been looking at GPS trackers (which are £££) and was wondering if a GPS enabled phone would do the same job but cheaper. The trailer is stored in a barn on a farm and it could be a couple of weeks before anyone notices its been stolen.
Any ideas?
