Remote Switch on/off from distance with GSM

-

which best way turn on/off arduino in great distance 10/50/100 kilometers ?
is sms message fast activate in less minute ?
otherwise can 3g ?
any otherway maybe in such huge distance ?

ps board not have ethernet or wifi

gsm appear option range.

if need simple relay control can buy off-the-shelf gate openers http://www.ebay.com/itm/gsm-gate-opener-wireless-door-access-free-call-remote-control-by-phone-rtu5024-/222062213024?hash=item33b3f077a0:g:3l8aaoswoudw1~jp less cost of arduino , gsm shield.

Indesign and MathType fonts

i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
