Virtual Mobile Operators

Tuesday, August 31st, 2010

A very short post this week… more of a reference table than a post really! In the UK, there are only 3 physical phone operators. All the others are Virtual Operators, i.e. they use the infrastructure from another operator. They may route the calls differently, or direct you to another directory enquiries – but the masts they use is from the physical operator. This is particularly important if you are having coverage trouble; it would be pointless to leave Orange for Blyk mobile because you don’t get a signal in your house as Blyk shares the masts with Orange.

Virtual Operator Physical Operator
3 Orange in non-3G areas
abica 3, Orange and T-Mobile
ASDA Mobile Vodafone
Blyk Orange
BT Mobile Vodafone
Fresh Mobile T-Mobile

Mobileworld T-Mobile
Sainsbury Mobile O2
Talkmobile T-Mobile
Tesco Mobile O2
Virgin Mobile T-Mobile

Coming next week… time permitting… either a rant on single-use codes for videogames or a theme I’ve wanted to do for a while, which illustrates exploits for things that people don’t assign value to (e.g. medical data, birthdate, address, etc). Hopefully, even if one person changes their behaviour and protects themselves more because of reading this,  I will be happy!

What Secrets Can Your Printer Tell?

Monday, August 23rd, 2010

So my work life has started to find its rails again, and I’m going to start posting again. Albeit at a reduced rate for now. Today, we’ll start with an interesting topic that crossed my mind last night.

It was actually a combination of things really; first I got an email from the Sec urity Controller at one of my clients. Along with everyone else working in a certain building, I was reminded that I shouldn’t leave protectively marked documents on the printer tray. The email was quite helpful, and went on to include a how-to on setting a job not to print on the printer until you typed a 4-digit PIN into the printer. Great. (more…)

Apologies

Tuesday, August 3rd, 2010

My apologies for the lack of posts recently – my professional life has taken an interesting turn. That said, in every challenge there is an opportunity; so I’m rolling up my sleeves and going for it.

Normal blog posts will resume asap; in the mean-time, if anyone is needs an IT Sec consultant, drop me a line! Until then, I’ll be working on distributing my CV…
