When I signed up to Toggle earlier in the year, the helpline lady told me that they can enable/disable IMSIs from their console position on request. Takes a couple of hours...
This suggests our mythical airline pilot (?) or truck driver could travel to more than nine countries in a 30-day period and still get service.
I'd imagine he'd also be a candidate for Toggle's promotion of customer of the year!
