Root access= phone administrator=needs to be allowed by user, so only affects ****tards.

You need to ask your possible installers how much they are going to charge you per month for the Securecomm service, there are different prices for different levels and if over wifi or gsm.
I've installed all 3, all have had some problems in 1 way or another. Personally I would go Texecom or HKC, I do think the Texecom is more user friendly and their App is free with no monthly charge, there is a monthly charge for the HKC App.
I assume the you have entered the no-ip details in your EE routers ddns section and not the tp link nano
If it doesnt have one then you can run an updater program on a pc/laptop, it's called Homing Beacon
