Top ten travel tips

Published

on

With Christmas and New Years only a few days away, South Africans are beginning to hit the beach and go on holiday. Tariffic offers the top ten travel tips to avoid cellphone bill shock.

  • Not all roaming networks are created equal
  • It is important for you to research which networks will be the cheapest to roam on when you are overseas and manually connect to the cheapest networks when you land. Roaming rates in some cases vary drastically depending on which network your phone automatically connects to upon arrival in a country overseas.  For example, if Tshepo, with an MTN SIM while roaming in the United States, connects to AT&T, she’ll pay a cool R1/MB for data roaming, but if she happens to connect to the T-Mobile network, she’ll pay a massive R225/MB for data roaming!
  • Don’t use data roaming unless you absolutely have to
  • While some countries have more favourable data roaming rates, others, like Thailand will cost you anywhere between R120.27/MB on Telkom to R300.00/MB on MTN. So a couple of Instagram sessions for Howard could easily cost a few thousand rand!   It is best to rather turn off data roaming when its not 100% necessary and rather connect to WiFi networks where available.
  • Save money by buying a local SIM card when you land
  • Try buy a local prepaid SIM card when you land which will be much more affordable when making local calls and using local data while overseas.  It may be worth considering a dual SIM phone if you travel often so that you can still receive calls on your South African number but can make calls and use data with a local SIM.
  • Try not to make local calls with your South African SIM card
  • Some networks have fairly competitive rates for local calls while overseas, such as Cell C’s R1.87/min rate in the United States, but it is often very expensive to make a local call with your South African SIM card with calls in Thailand for example costing R15/min on MTN. Rather try connect to a local WiFi hotspot and make free calls using Skype, Whatsapp, or Facebook calling.
  • Beware of answering incoming calls
  • Answering calls from South Africa can become a very costly exercise while you’re traveling with rates as high as R27.64/min to receive a call in England if you’re on Cell C.  Rather notify your friends, family, and colleagues that you’ll be away and ask them to rather SMS or Whatsapp you.
  • Turn off voicemail when travelling abroad
  • Did you know that if you’re overseas and someone calls your phone and leaves a voicemail message, then you’ll pay for that call?  This becomes really expensive when you consider that you’ll pay international calling rates for that call, so if Chris is on Telkom and receives a one minute long voicemail message while he’s in Mauritius, it could cost him R14.23.
  • Save money with roaming deals
  • Many of the networks now offer roaming deals, which give you access to cheaper roaming rates in certain countries, for free or for a daily fee.  Examples of this include Vodacom’s Travel Saver and MTN’s Roam Like Home.
  • Rather receive a call from South Africa than call South Africa from overseas
  • Want to speak to loved ones in SA while you’re overseas?  It often works out much cheaper to receive a call from overseas than it is to call from overseas to South Africa.  For example, it could cost you R23.50/min to call South Africa from America on Vodacom, but will only cost R6/min to receive a call from South Africa.
  • Rather use WhatsApp on WiFi than SMS
  • SMS rates vary from country to country with MTN’s rates ranging from R1/SMS (if you’re in the US), to R7.50 (if you’re in Thailand), so a quick convo between Howard and his bae can add up pretty quickly.  Just think that a few emoticons could land up easily costing him over R100! Rather use Whatsapp than SMS.
  • Find the perfect cell phone contract based on your travels
  • If you consider yourself a global jetsetter, then get in touch with Tariffic where we can analyse how you use your phone to scientifically find the perfect cell phone package for you based on your lifestyle.  This will include the best package to make international calls based on your previous usage.  We’re saving companies and consumers up to 50% on their cell phone bills, so let us do the same for you.

Earth 2050: memory chips for kids, telepathy for adults

An astonishing set of predictions for the next 30 years includes a major challenge to the privacy of our thoughts.

Published

on

Buy 2050, most kids may be fitted with the latest memory boosting implants, and adults will have replaced mobile devices with direct connectivity through brain implants, powered by thought.

These are some of the more dramatic forecasts in Earth 2050, an award-winning, interactive multimedia project that accumulates predictions about social and technological developments for the upcoming 30 years. The aim is to identify global challenges for humanity and possible ways of solving these challenges. The website was launched in 2017 to mark Kaspersky Lab’s 20th birthday. It comprises a rich variety of predictions and future scenarios, covering a wide range of topics.

Recently a number of new contributions have been added to the site. Among them Lord Martin Rees, the UK’s Astronomer Royal, Professor at Cambridge University and former President of the Royal Society; investor and entrepreneur Steven Hoffman, Peter Tatchell, human rights campaigner, along withDmitry Galov, security researcher and Alexey Malanov, malware analyst at Kaspersky Lab.

The new visions for 2050 consider, among other things:

  • The replacement of mobile devices with direct connectivity through brain implants, powered by thought – able to upload skills and knowledge in return – and the impact of this on individual consciousness and privacy of thought.
  • The ability to transform all life at the genetic level through gene editing.
  • The potential impact of mistakes made by advanced machine-learning systems/AI.
  • The demise of current political systems and the rise of ‘citizen governments’, where ordinary people are co-opted to approve legislation.
  • The end of the techno-industrial age as the world runs out of fossil fuels, leading to economic and environmental devastation.
  • The end of industrial-scale meat production, as most people become vegan and meat is cultured from biopsies taken from living, outdoor reared livestock.

The hypothetical prediction for 2050 from Dmitry Galov, security researcher at Kaspersky Lab is as follows: “By 2050, our knowledge of how the brain works, and our ability to enhance or repair it is so advanced that being able to remember everything and learn new things at an outrageous speed has become commonplace. Most kids are fitted with the latest memory boosting implants to support their learning and this makes education easier than it has ever been. 

“Brain damage as a result of head injury is easily repaired; memory loss is no longer a medical condition, and people suffering from mental illnesses, such as depression, are quickly cured.  The technologies that underpin this have existed in some form since the late 2010s. Memory implants are in fact a natural progression from the connected deep brain stimulation implants of 2018.

“But every technology has another side – a dark side. In 2050, the medical, social and economic impact of memory boosting implants are significant, but they are also vulnerable to exploitation and cyber-abuse. New threats that have appeared in the last decade include the mass manipulation of groups through implanted or erased memories of political events or conflicts, and even the creation of ‘human botnets’. 

“These botnets connect people’s brains into a network of agents controlled and operated by cybercriminals, without the knowledge of the victims themselves.  Repurposed cyberthreats from previous decades are targeting the memories of world leaders for cyber-espionage, as well as those of celebrities, ordinary people and businesses with the aim of memory theft, deletion of or ‘locking’ of memories (for example, in return for a ransom).  

“This landscape is only possible because, in the late 2010s when the technologies began to evolve, the potential future security vulnerabilities were not considered a priority, and the various players: healthcare, security, policy makers and more, didn’t come together to understand and address future risks.”

Pizoelectrics: Healthcare’s new gymnasts of gadgetry

Published

on

Healthcare electronics is rapidly deploying for wellness, electroceuticals, and intrusive medical procedures, among other, powered by new technologies. Much of it is trending to diagnostics and treatment on the move, and removing the need for the patient to perform procedures on time. 

Instruments become wearables, including electronic skin patches and implants. The IDTechEx Research report, “Piezoelectric Harvesting and Sensing for Healthcare 2019-2029”, notes that sensors should preferably be self-powered, non-poisonous even on disposal, and many need to be biocompatible and even biodegradable. 

We need to detect biology, vibration, force, acceleration, stress and linear movement and do imaging. Devices must reject bacteria and be useful in wearables and Internet of Things nodes. Preferably we must move to one device performing multiple tasks. 

So is there a gymnast material category that has that awesome versatility? 

Piezoelectrics has a good claim. It measures all those parameters. That even includes biosensors where the piezo senses the swelling of a biomolecule recognizing a target analyte. The most important form of self-powered (one material, two functions) piezo sensing is ultrasound imaging, a market growing at 5.1% yearly. 

The IDTechEx Research report looks at what comes next, based on global travel and interviewing by its PhD level analysts in 2018 with continuous updates.
