Mobile Network Comparison

Three Mobile are rolling out a brand-new scheme to help you save money when using your mobile abroad. Called Feel At Home, the new deal completely abolishes all roaming fees you would usually have to pay when travelling in a select few foreign countries.

We’ve lost count of the number of times we’ve heard of mammoth bills caused by overseas roaming charges. Even within the EU, it is easy to run up £100s in a few hours browsing the internet and even a quick call to loved ones back home can cost more than your hotel room for the night. Things are often an order of magnitude worse if you’re visiting countries not in Europe.

Most of us are aware that when we go on holiday, we will be restricted to communicating with people back home during infrequent visits to desperately-slow internet cafés. While this means that we can really concentrate on relaxing and enjoying ourselves while we are away from home, sometimes emergencies can crop up. And this can mean that you urgently need to get in touch with people back in Blighty. Or, if you’re away for a really long trip, it’s definitely nice to be to call your significant other for a quick chat or check in with your folks.

Previously the prices have been exorbitant and completely unaffordable but Three’s new deal will make a difference, at least for a few destinations. When you’re travelling in Austria, Australia, Denmark, Hong Kong, Italy, the Republic of Ireland or Sweden you only have to pay the normal UK rates for making calls, sending texts or even browsing the web with your mobile data connection. Presumably these particular countries have made the list because Three’s parent company – Hutchison Whampoa – have business relationships with the operators existing there and have worked out some sort of deal.

Even better, if you have an inclusive allowances that provide a certain amount of minutes, texts or megabytes of data, these will still be usable when you roaming. So when you’re on holiday, you can use up your monthly allowance that would otherwise end up going to waste. And with many Three Mobile tariffs including unlimited data, the possibility of saving huge amount of money on roaming internet access are huge.

The only thing you have to look out for is that the offer only includes calling and texting UK numbers back home. You can’t make roaming calls to other countries or even the local country you are currently travelling in. Even so, there is nothing to complain about and it’s a great deal for all Three Mobile customers. Best of all, you don’t even have to do anything to activate the offer. You will be opted in automatically and will start saving as soon as your phone starts roaming on a network in any of the countries that are included.

We think this is great news as, traditionally, roaming charges have hit consumers’ wallets hard. Most the time, the mobile networks have done little to make this any better and have happily pocketed profits they’ve been making. Now, it’s almost worth picking up a Three Mobile PAYG SIM if you’re going away to one of the countries listed for about a couple of weeks.

Once again, it’s been down to Three to pioneer a new way of doing things that puts customers first. We can only hope that this hots up the competition for overseas roaming and that we see other networks follow suit with their own alternative offers to help you save money. Were also certainly interested in seeing which countries to the sized at next to the Feel At Home plan.

Did you use your mobile much last time you away on holiday? What’s the most expensive roaming bill you have ever been hit with? And what do you think of this new offer – will you be using it and do you think that the other networks will follow suit soon?

After some time of rumours, BlackBerry have admitted that over 4,000 of their staff will soon be without a job. Still struggling from lacklustre sales figures of their newest Blackberry 10 devices, the Canadian handset manufacturer released the news straight after the release of Apple’s latest flagship product – the iPhone 5S. In many ways, the rise of smart phone as brought about by Apple has been the catalyst for BlackBerry’s downward spiral of the last few years.

Indeed, it is probably true that Apple have wrestled the majority of their big spending corporate and high-end customers. Most sucessful handset manufacturers these days – companies like Samsung – have learned to compete with diversity in their product lineup and by offering cheaper options rather than trying to compete with Apple for the super high margin top-of-the-line products.

BlackBerry CEO Thorsten Heins may now be ruing his strategic decision to focus on the upper end of the market. He made it clear that he considered making budget smart phones a race-to-the-bottom and that the Canadian company would be concentrating on its traditional strong grounds of expensive handsets only affordable by very few. Ironically, this decision was seemingly made in ignorance of the fact that in recent times probably the only people keeping BlackBerry afloat have been teenagers who use their BBM service as a cheaper form of text messaging.

Indeed, the company’s balance sheet has been hurtling downwards in perpetual freefall for sometime now. The latest figures show that the last quarter produced losses of nearly $1 billion primarily due to poor sales figures. In fact, their revenue fell far short of the predicted $3 billion with the company only taking about half that over the last three months.

Other issues that have caused BlackBerry to come into difficulties over recent years include the massive ongoing outages that happened almost exactly 2 years ago now. During these disruptions, millions of customers – many of them urgent business requirements – were left without access to e-mails or BBM messages several days. and of course, BlackBerry also lost untold amounts of cash over their failed venture to produce the BlackBerry Playbook tablet.

In fact the company struggled to sell even 4 million smartphones during the last quarter and the last time the figures were this poor was the same summer that the first iPhone was released by Steve Jobs. Their share price has also been plummeting in light of rumours about these figures and this has wiped billions of dollars off its value in just a few days.

The latest disappointing figures round off an awful couple of years for BlackBerry that has seen them lose a total of almost $2 billion. With substantial losses such as this, it remains to be seen how much longer they can continue as an operating company. BlackBerry have been looking for an external buyer for sometime now, but no deals have been forthcoming yet.

Things aren’t looking better for BlackBerry in the future either. After many rumours, the iPhone 5S really did have a fingerprint scanner and has now been released. It is being marketed as having ever more robust security features and will surely take another chunk out of BlackBerry’s customer base. Indeed, if Apple can persuade companies and governments that their sensitive information will be secure on iPhones, we can see many large contracts moving over from BlackBerry who used to be their traditional supplier.

Perhaps the most dire news of all is the recent industry-shaking sale of Nokia to Microsoft. It was thought that BlackBerry were courting Microsoft as a last gasp chance to gain any sort of meaningful foothold in the fast paced and ruthless smart phone market. This deal surely binds the two companies together for some time and effectively leaves BlackBerry as the left out third wheel.

And they’s certainly not going to be any love forthcoming from Google or Apple either. Without a relationship with any of the three major phone software companies in today’s mobile ecosystem, it’s hard to see how BlackBerry can have any meaningful place in the industry in the coming years.

Only two years ago, BlackBerry had a significant share of the smartphone market but now the latest figures show that it has less than 5%. Their CEO claimed that their flagship handset the Q10 would sell tens of millions but the actual sales figures are looking to be closer to just five million.

And as a result these job losses have pretty much been forced upon the company. There were already 5,000 redundancies last year followed by some more in the summer. The 4,500 who are being sacked now will reduce BlackBerry’s employees by almost a half. Their hope and prayer is that in the process the they will also slash their expenses and somehow return to profitability. We are unsure whether this will be possible after such a long time of haemorrhaging cash and struggling to make any meaningful difference in a market that appears have moved on from them.

What’s your take on all this? Do you think that there’s any future left will BlackBerry and if not how many more years will at last? Was the purchase of Nokia by Microsoft really is death knoll? Or had the end come earlier? And if you think that BlackBerry will survive all this and emerge again to be a successful company, how do you think they’ll go about doing it?

Back in April, Giffgaff suffered a partial network outage for a few hours. We liveblogged the event throughout the evening and later, Mike Fairman, the “gaffer” and CEO of Giffgaff issued a formal apology on the Giffgaff blog.

However, we wanted to dig a little deeper and find out the exact explanation for the series of events that led to the outage. After all, many things must have gone wrong to lead to the particular situation that left untold thousands without any mobile signal for several hours. And since there was another widespread outage at Giffgaff only last Friday, what better time than now to look back at the past mistakes have been made? [edit: There’s been another widespread outage tonight since we published this post. Seriously!]

This is especially true as there had only recently been an O₂ issue in October the previous year after which Derek McManus, the Chief Operating Officer, promised a £10 million investment in infrastructure to prevent the same thing happening again. There had also been a major 24-hour outage in July which prompted Telefónica UK CEO Ronan Dunne to apologise and offer compensation to >O₂ customers as well as a small outage on Giffgaff in March last year.

Given these previous issue and the promises of substantial investments in infrastructure to avoid further outages, we feel it’s only fair for customers to know the root cause and the decisions that led to them being without their phone for such a long time. Previously we investigated the true details of the big O₂ outage so now we’re aiming to do the same for this one.

Giffgaff usually have excellent communication and kept users up to date through the forums while the issue was ongoing. They also posted several blog posts detailing the causes of the outage and what prophylactic measures would be taken in the days and weeks after service was restored.

Charl Tintinger, Head of Operations at Giffgaff, made a blog post explaining in detail what happened. Effectively, his explanation was that a third party supplier “experienced a mains power failure, which resulted in a service wide outage”.

Now this may seem like an explanation, but it’s actually ignoring some very important issues. First of all, anyone who works in telecoms knows that it takes more than a power outage to interrupt critical systems than affect uptime and necessary services. The standard configuration for any data centre is for them to use normal mains power from the National Grid but, in the event of an outage, to automatically transfer to battery powered Uninterruptible Power Supplies (UPS). These keep the systems alive until the power is restored or, if the outage is ongoing, allow for a smooth transfer to backup diesel generators. These generators should automatically kick in and start pumping out electricity before the batteries die.

Data centers rarely just rely on just battery UPS devices for emergency power – in fact, many even have secondary backup N+1 generators to provide additional redundancy. Critical services can take this even further. After all, the people who run mission-critical systems like this have learned over the years that, WTSHTF, outages can last longer than a few hours. It’s better to be prepared for the worst.

However, Giffgaff’s statement said that the reason for this outage was that the “backup power system” was “depleted before the issue was completely resolved”. Now backup generators typically have about a week’s supply of diesel – there’s no way this would have been going on for so long without the administrators being notified or the issue being resolved. So it sounds like there are two possibilities – either the data centre Giffgaff had outsourced to didn’t have backup generators or there was some sort of switchover failure when transferring from the UPS power to the generators.

Both of these possibility distinctly call into question the competence of the third-party Giffgaff were using as well as why they were chosen. It’s a real shame that they were not explicitly named nor was it mentioned whether they’d still be supplying services for the mobile network. After all, it is standard practice to have a Service Level Agreement that guarantees a certain level of uptime. For example, some service providers might promise a high availability of services where the downtime is less than 5.26 minutes per year – this is the equivalent of 99.999% availability (commonly referred to as “five nines”). Service Level Agreements are standard practice in telecommunications – it is not uncommon for network service providers to explicitly state their own service level agreement on their websites.

Giffgaff have said that “The data centre have already updated some of their processes and implemented some physical monitoring on the boxes should the direct power be lost and battery power start to be used”. They have also claimed that “the monitoring on the network nodes is being reviewed so that they alert at the right time, giving engineers enough time to get to site before the back up power is at risk”.

You do expect to get the quality of service you pay for and this sounds suspiciously like the data centre was not meeting modern standards or that someone messed up pretty severely. There certainly shouldn’t be issues with monitoring the power supply to critical systems and we sincerely hope that Giffgaff are reviewing their contract with this third party.

For those of you who want a bit more detail about the particular system that was affected, Giffgaff have said that it was a “piece of hardware that manages calls and texts on the network”. This might not seem like the most helpful explanation but let’s think about how a mobile network is structured.

There are three main parts of the core Network Switching Subsystem – the Mobile Switching Centre (MSC) which effectively sets and releases all connections, the Visitor Location Register (VLR) which stores information about the physical location of each subscriber and the Home Location Register (HLR) which holds information about each subscriber’s SIM card and phone number. Although we don’t have so much information, we can be reasonably sure that this particular outage was due to some part of the Network Switching Substation.

Anyway, we hope that explains a bit more of the details behind this outage. Hopefully now you have a better idea how a mobile operator works and what can be done to avoid these sorts of issues. Thankfully, this outage is now well in the past. Although we are becoming increasingly reliant on our mobiles, a few hours without signal is usually not an emergency and hopefully can be filed away under first world problems.
