Does PTCL EVO work when mobile services are blocked in the country?

Hello all,

I'm trying to find a way to keep in contact with friends n family whenever government shuts down mobile services for so called security reasons. My research has led me to the conclusion that vfone is also blocked during the mobile blackout so I'm assuming that Worldcall wireless phone services are also included in the blockege. The only thing that remains to be found out is if PTCL EVO services are also down during such a blackout becasue if they are not, I'm contempleting buying either the PTCL EVO Tab, or, a much cheaper alternative, UFone Futura EVO phone becasue the requirement is just to keep in contact through txt or call, nothing more. So, can any user of PTCL EVO confirm if its on or off during mobile blackouts?

Also, does anyone else have any alternative ideas for keeping connceted with family in such a situation?
