Staying connected in the air

I promised Nicole that I would limit posts on airplanes and related topics, but I thought this was one worth mentioning.
Noticed the below indicator on one of our flights on Royal Jordanian. In case you don't figure it out, its a no-phone indicator. This particular flight apparently offered inflight mobile service. Gave it a try, but unfortunately couldn't get it to work.
Probably better to avoid bothering a cabin full of people and running up those international roaming charges.
