    5G service is appearing in parts of Chennai, in Jio Network

    The long-promised 5G is finally in Chennai. I got this speed in my iPhone 12 Pro with the iOS 16.2 (20C65) update running on the Jio 5G network. Currently, Jio seems to be running a free trial offer for 5G. Speedtest pictures seen below were taken from a car (I was not driving) while travelling from Marina Beach to Santhome, Beach Road, Chennai. I also noticed 5G in the T. Nagar shopping district near Panagal Park. In another mobile, this one with Airtel I am seeing only 20Mbps with a Samsung Galaxy S20FE phone. Of course, 5G speeds are said to be more location/tower dependent.

    Protect your SIM card

    சமீபத்தில் என் ஐபோனின் சிம் கார்டை ‘இ-சிம்’மாக, அதாவது சிலிகான் அட்டையாக இல்லாமல் மென்பொருளாக மாற்ற ஒரு தொலைபேசி நிறுவனத்தின் கடைக்குச் சென்றேன். என் ஆதார் அட்டை, ஆள்காட்டி விரல்ரேகை, புகைப்படம் என்று (பாஸ்போர்ட் புதுப்பிப்பில் கேட்கும் தகவல்களை போன்று) யாவற்றையும் விரிவாகக் கேட்டு இருபது நிமிடங்களுக்கு மேல் எடுத்துக் கொண்டு செய்து முடித்தார்கள். நான் பொறுமையாகக் காத்திருந்தேன். வேலை முடிந்தவுடன் அந்த ஊழியரிடம் நன்றி கூறினேன். அவர் ஆச்சரியத்துடன், “பொதுவாக இந்த அளவுக்கு நாங்கள் கேள்வி கேட்பதற்கு எல்லோரும் கோபித்துக் கொள்வார்கள். நீங்கள் ஒருவர்தான் சிரித்துக் கொண்டு எல்லாவற்றுக்கும் பதில் கொடுத்தீர்கள்!” என்றார். ஏன் பொறுமையுடன் இருந்தேன் என்பதற்கான காரணத்தை இந்த வாரம் மெட்ராஸ் பேப்பரில் வந்துள்ள எனது கட்டுரையில் படிக்கலாம். நினைவில் கொள்க, செல்பேசியின் ஆத்மா என்பது அதன் சிம்-கார்டு. அதை பாதுகாப்பது நம் பொறுப்பு. #simcard #safety

    Blackberry Town by Chuck Howitt

    With the dominance of Apple and Google on the mobile phone market in the last decade, I feel puzzled and sorry for the two earlier leaders in the space – BlackBerry and Nokia. Both were dominating mobile giants and not from the USA. BlackBerry was from Canada, a country I have travelled to briefly on a weekend trip to Vancouver from Seattle. Even today in tech circles I hear people talking with high regards for the technology chops of BB. As a result, I always wondered where the company stumbled and this book “BlackBerry Town” by Chuck Howitt will shed some light to it. As I started reading the book…

    Move from Android to iOS and transfer WhatsApp from Samsung Phone to iPhone

    With the public backlash against WhatsApp with their privacy policy revision, this may not be the best time for this post, but still here it is. I recently got a new iPhone. I am coming to an iPhone after exactly a decade, my last was iPhone 4 in 2010 and now it is iPhone 12 Pro. While waiting for the new phone, I made a check list of all the items and apps that needed to be moved from the Android phone (Samsung Galaxy S10 Lite) and where their data resided: Contacts – Google Contacts Calendar – Google Calendar Mail – Microsoft Outlook and GMail Notes – Evernote and Google…

    For Apps is Mobile first and Web last?

    As a farewell thought for 2020, let me leave you with an observation of a trend of last few years that got cemented this year. As an early developer for the web, I had believed that applications will get developed for the web first, depending on the market you then write native apps for iOS and/or Android. Using iPhone for the last few weeks, I am observing it is the other way round nowadays. Even if there is a web version of an app they are crippled compared to the native mobile apps. Look at Instagram where posting is not available on the web version (for God’s sake, why?), or…

    An open letter to Facebook - what is a story, and do we need it?

    Dear Facebook, Please understand that not everyone is as smart as your product managers, I am not. I don’t understand the UI for the “Your Story” feature on the web. When I see a notification that a friend has posted a new story, I click and I get a weird looking “mobile” like window which goes away even before I can read the whole post or story or text or whatever you are calling it today. And, if I reply to a story, I am unable to figure out where it went. If the “Story” is having a video, why am I not given any of the controls – to…

    Anyone for a premium mobile service?

    The mobile market in India has (stabilised) become an Oligopoly play – with Airtel, Vodafone and Jio racing to the bottom (~lower ARPU) with ever poor customer service. I am leaving out Government owned BSNL & MTNL as I see no future for them – both have surrendered their 4G spectrum many years ago. In this scenario, I see an opportunity for luxury brands to offer a white-labelled service (backhaul provided by one of the 3 players). I will be happy to pay more for such a premium service. This SIM Card can include industry-leading privacy controls, identity protection, call/message screening options, concierge services, doorstep SIM replacement, fastest speeds in…

    How my son got back his lost phone

    Over the years, I have become more and more careful with my belongings especially in keeping them safe while travelling. Rarely I do misplace or lose items. One such time was last year when I lost my iPad at a Microsoft Conference in Atlanta, USA and got it back. Today was the turn of my teenage son. Yesterday evening, I and son had landed at Chennai Airport after a good vacation at Kerala’s Kumarakom and my son had forgotten to take his small bag from the trolley we used. He didn’t miss it, till today morning. Morning, he got up and was frantically looking for his phone all around the house.…
