Hi
You are more or less correct, but let me help straighten out a few
points...
ionCube is free, you only need the loaders which are provided free,
it's just if your current hosting company will install the loaders in
the php.ini file, or if they won't/can not then you can still load the
required files at run time.
The hosting gtrack provides is full hosting, the only thing not
provided is the domain name which we recommend you control anyway from
a 3rd party such as
123-reg.co.uk so you can use the hosting for
anything else as well.
The gtrack software allows unlimited vehicles / users / phones to be
tracked, not just 1 :)
The T-Mobile data SIM does have roaming ability at £1.50 per MB, this
is used on top of the normal monthly charge if you go out of the UK,
but if you don't move for 2 weeks while away, you won't incur costs :)
You could use a PAYG SIM and then 'tweak' the data settings for
something cheaper.
The good thing about our trackers is they will only send data once the
vehicle has move more than xxx meters from its last position, so like
above, if no movement, then no data is sent.
And of course you can change the frequency of the data updates at will
by simply sending the unit a new command, so if you pop-over the water
you can simply turn your tracker off, or make it update every 2000
meters instead of 1000 meters for example, saving more.
