x-no-data-charges


Screenshot of a Symbian mobile phone asking "Opening a secure connection. Yes or No?"

Here's an idea that can't possibly work. People used to pay-per-minute for telephone calls. Some numbers were "zero-rated". That is, if you called them you wouldn't be charged. At first it was calls to the emergency services which were free. Businesses and other organisations realised that it was good customer service to provide a free-to-call number. Generally speaking, this means that the called-party pays the phone company for incoming call rather than the caller paying. Thus 0800 numbers…

Best Bulk Data PAYG SIMs in the UK

How much money I've spent on mobile calls / text / data in the last year


The Doctor holding Ryan's phone.

A couple of months into the pandemic, I realised that I was vastly overpaying for my mobile usage. I was paying £10/month for unlimited calls, texts, and 8GB data. That's a pretty reasonable price, but I was sat at home all day on WiFi - so I had no need for data. I don't send SMS any more - all my friends and family are on Signal / WhatsApp / Telegram etc. And, it turns out those services also do free video and voice calls. So why was I paying for stuff I didn't need? So I switched to a …

Why spam calls come from similar numbers to your phone number


Can of Spam. From https://www.flickr.com/photos/27308606@N04/3920588954/in/photolist-6Ys3vh-D4tFyP-5Nfafk-4YquSL-j76egA-b4ThXT-j71TQi-4C6NQo-4zGP8b-8jBWuu-9NZujn-4mZsmC-Skcx6h-6qY9vr-hNh67-5Hf4WS-mSRtT-718hHC-71HDFc-kCAL2L-2NYWTK-kCANQm-6eLuK-6cSS7G-vVZqB-79Z3X-dgu3-4sqgZw-8WuDpp-5FQ3yz-4nFSR8-563Gj-mb7gL-39uw1-5f1fho-2NiBSN-5pDMMS-8b9Hjq-pRrxLR-hfXfA-5xmaj-9vw9hx-o9bd3k-258kqqN-tuDnQ-8YeJPL-5hrex8-pFKpm-vSKr9b-39r59D

In the last few months, I've received dozens of spam calls which appear to come from a similar phone number to mine. If my number is 07700 900 123 I get calls from 07700 900 124 or 07700 900 456 Here's my working theory on why spammers do this. Americans. In the UK, there's a separate "area code" for mobile phones. If a number starts 07 then it is mobile (it's a bit more complicated than that). In the USA, there's no cellular prefix. If you buy a SIM card in Las Vegas, you'll probably get…

Mobile data is getting too cheap to meter - free bandwidth is here


List of price plans. Free for 250MB, £1 for 500MB, £6 for a GB.

A few months ago, I wrote about how data is so cheap it is being given away. Mobile network Three were offering £10 data SIMs which came with 200MB of zero-cost data. Recently, I've found another free provider of data, with an intriguing price-plan. RWG Mobile are a Welsh MVNO who use EE as their backhaul. As well as the usual high-end plans, they also have this at the lower end. Yup! A free SIM with 50 UK minutes / SMS included. Think about how much calling and texting you do each month. …

My solution to spam calls


The Amazon Polly config screen.

Like most of you, I'm inundated with spam calls. So I have a new solution. When an unknown number calls me, they get routed to this audio file. 🔊 💾 Download this audio file. This was created with Amazon Polly which is free for casual use. I was pretty impressed with the voice quality. Although there are limits to how well you can control the speed and intonation. While there are a number of accents available, there are only a small number of distinct voices in British English. T…

Using SipGate to set up a BANANAPHONE!


A developer console.

Like many of you, I'm inundated with spam calls. I've suffered endless car accidents, my National Insurance Number has been suspended multiple times, and my broadband will be cut off imminently. Wouldn't be nice to screen out all the fraudsters? So I've set up a Bananaphone. When people ring me, they get 30 seconds of my favourite song. Then the call is passed to me. The theory being that my friends get to enjoy a short ditty but con artists are likely to hang up before the call connects to…

How much does it cost to call an 056 number in the UK?


Old BBC News website. Net calls get their own area code Blue police lamp, BBC Fixed phone firms must give access to emergency numbers In the UK, the telephone area code for cyberspace will be 056. Government regulator Ofcom has picked the prefix for customers who sign up to make calls via the internet. Users can also opt for geographic numbers. The decision on numbers comes as Ofcom reveals how it plans to regulate services that use the net rather than the old fashioned telephone network.

Here's a little telephony mystery for you - can you find out how much your phone provider charges for 056 calls? (Skip the background and jump to the survey) Background Way back in the mists of time - 2004 - Ofcom decreed that "Voice over Broadband" was going to be the next big thing. VoB (which is like VoIP, but specifically tied to a broadband line) would receive the prefix 056. In that document, they suggested a price cap of 5 pence per minute - considerably lower than other services -…

Cell Broadcast Emergency Alerts being tested in the UK


Pop up which says "This is a test message. This is an O2 Test Message to test Cell Broadcast. No action required. In future, alerts like this one may be used to warn you about a danger to life in the local area.

I have only been on the periphery of this project - back from when I worked at a Mobile Operator - so it's incredibly exciting for me to see this come to life. This morning, my phone picked up an Emergency Alert test from the Cell Broadcast system. I had to specifically opt-in to receive test messages. Each phone is different, but on Android I unlocked developer options and found the alerts settings within notifications. Your phone will almost certainly have the option somewhere else. …

Data is so cheap it is being given away


Advert for 200MB of free data.

Giving up on phone contracts


Table showing my mobile usage. 5 minutes, 4 texts, 1 MB.

Another weird economic casualty of COVID19. I'm not wearing out my socks and shoes. I cancelled my train season ticket. And now, I'm giving up my mobile contract. For a decade, I worked in the mobile industry - and always had an unlimited SIM card. Rejoining the real world, some years ago, was a bit of a shock to the system. You mean people have to pay for phone calls?!? The pandemic has everyone reassessing their finances, right? Do I need that beer-of-the-month subscription? Should I move …
