To celebrate the upcoming series Doctor Who staring Jodie Whittaker, I'm attempting to chronicle all the mobile phones used in previous shows. If you think you've spotted something that's not listed here, or think I've made a mistake, drop it in the comments. You can follow along with all 10 series. Rose From the start […]

My mobile provider - Three UK - offers WiFi calling, but only if you have a phone purchased directly from them. For everyone else, they have a crappy app which hasn't been updated in two years. So, let's break out of their artificial restrictions and get some WiFi calling on the OnePlus 5T! Step-by-step Open […]

Interesting Failures - Group Calling

Another in an occasional series of blog posts where I discuss products I've worked on which failed. It boiled down to this. Was there a way we could make normal people want to be on a conference call with their family and friends? Let me explain. ARPU - Average Revenue Per User - that's all […]

Interesting Failures - Visual IVRs

by @edent | # # | 2 comments

Another in an occasional series of blog posts where I discuss products I've worked on which failed. It was the early 2000s and the large mobile telco I worked for had just spent billions of pounds on a 3G license. 3G was the future! Sure, faster data would be nice, but the real money was […]

Review: Svpro 3D Camera - for Android and Raspberry Pi

I've been sent a 3D camera addon to review - the Svpro SV-2560X3D-001 is a £65 stereo camera designed for Android. It will also work with a Raspberry Pi! It looks a little like a Microsoft Kinect - a single bar with two embedded cameras. The camera resolution is 720p on each lens. You can […]

Walking back from work yesterday, I noticed an unusual set of chuggers - those faux-cheerful folk who try to stop you in the street asking for money. They were fundraising for Unicef. Rather than handing out flyers they were carrying high-tech VR headsets! Using the headset, I was able to take a virtual tour of […]

You need a SIM card in your phone to dial 999

by @edent | # # # # | Read ~1,846 times.

I want to correct a common misconception. Many people think that you can dial the emergency services even if you do not have a SIM in your phone. I see this advice scattered around the web - often telling people to keep an old, SIMless phone for an emergency - and it is dangerously wrong. […]

Many years ago, when I worked for a mobile phone company, a group of us were encouraged to come up with crazy ideas which the organisation could patent. I had one idea come this close to getting through until someone found an unnervingly similar patent and the whole thing was dropped. Well, it has been […]

App Showdown - Zapper ? MusicMagpie

by @edent | # # | 2 comments | Read ~271 times.

It is time for me to have a clear out. I've got hundreds of books which I've replaced with eBook, CDs which I never listen to, and DVDs I'm ashamed to own. Selling them individually on eBay or Amazon sounds like a lot of hard work... That's where Zapper and MusicMagpie come in. Both offer […]

A Brief History of Killing the Headphone Jack

by @edent | # # # # | 3 comments | Read ~1,761 times.

Is it the end-of-days for the humble headphone jack? As Apple prepare to remove it from their next iPhone - with Android manufacturers no-doubt following suit - I thought now would be a good time to look at the previous occasions when smartphone makers have tried to kill the headphone jack. This is a non-exhaustive […]
