Travel to China – ChunYun

The People's Republic of China (PRC), is a unitary sovereign state in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering approximately 9,600,000 square kilometres (3,700,000 sq mi). There are over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and the special administrative regions of Hong Kong and Macau.

Chinese New Year, also known as the Spring Festival, is an important Chinese festival celebrated at the turn of the traditional lunisolar Chinese calendar. People celebrate with their family and usually have a reunion dinner. This occasion is called “ChunYun”. Chun means Spring and Yun mean transport. Chun Yun is The Spring Festival Transport Season.

According to the data from Ministry of Transport of the People's Republic of China, there are 2.98 billion passengers who go on a domestic trip to China. The number of passengers is expected to exceed 3 billion according to the forecast for 2018. Among them, 393 million passengers are expected to travel by rail to home this year.

Travel to China - ChunYun

People are waiting at Guangzhou station to buy a ticket to return home. People need to wait for few hours or even a day to buy a ticket. 

In 2018, the last batch of the 90s will reach the age of 18, the new working force in China. They have grown up with the rapid development of the Internet, are more likely to buy a ticket on the Internet. Also because of the help of artificial intelligence and big data, the third-party ticket-grabbing platforms are more convenient and intelligent, which can help passengers to grab a more comfortable train ticket while improving the success rate of grabbing votes. All the above factors will improve the ChunYun experience and the travellers' ability to get around.

During the Spring “Chun Yun” Festival, most of the shops and factories are closed as the staff travel home to be with their families. However, I wouldn’t be recommended you travel in China during this period as a tourist. However, if you planned to go China in ChunYun period, you can experience peaceful China where families unite and spend some quality time celebrating the Spring period

Decoding cryptocurrency... Why not use it while you travel?


Cryptocurrency is a digital asset designed to work as a medium of exchange. Basically, it is in a digital format, and not physical cash. All the Cryptocurrencies are using decentralised control which works through a blockchain – meaning a public transaction database, functioning as a distributed ledger.

The first decentralised cryptocurrency is Bitcoin which was created in 2009. Until now, there are some popular cryptocurrencies worldwide – Bitcoin, Litecoin, Dogecoin and Ethereum.


Bitcoin is the most popular cryptocurrency and has a high reputation because it is reliable, stable, secure, and long-lasting. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment. Research produced by the University of Cambridge estimates that in 2017, there will be 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.


Litecoin was inspired by, and technically is nearly identical to Bitcoin. The initial release was in 2011 and until late 2017, its market capitalisation was US$ 4,600,081,733. Litecoin is focused on delivering a viable cross-border payment platform that would surmount the substantial barriers currently in place.


Dogecoin is a decentralised, peer-to-peer digital currency that enables you to easily send money online. Compared with other cryptocurrencies, Dogecoin had a fast-initial coin production schedule: 100 billion coins were in circulation by mid-2015, with an additional 5.256 billion coins every year thereafter. As of 30 June 2015, the 100 billionth Dogecoin had been mined. In December 2017, it had a value of US$1 billion.


Ethereum is an open-source, public, blockchain-based distributed computing platform and operating system featuring smart contract (scripting) functionality. It is focused on running the programming code of any decentralised application. The Ethereum Virtual Machine makes the process of creating blockchain applications much easier and efficient than ever before.


So what are the advantages of Cryptocurrency?

  • Easy access – You can access your cryptocurrency wallet anytime anywhere
  • Quick and easy payment – No exchange and coins
  • Costs less – Transaction fee is low in comparison to SWIFT/SEPA
  • Highly secure – No one can make any payment from the wallet unless you are the owner
  • No boundaries – It is not under the control of any central bank

Nowadays, more and more shops are accepting cryptocurrencies for payment.  Shopify shop owners can turn on BitPay functions to enhance their shop competitively, travellers can book flights via CheapAir or Expedia’s - an online platform which accepts cryptocurrency and Japanese e-commerce giant Rakuten also accepts it.  

Also, some of the worldwide chain restaurants like KFC (Canada region) and Subway are now accepting cryptocurrencies. This means that travellers don’t need to bring huge amounts of cash while travelling and it also and reduces international bank charges

Brisbane Airport (BNE) will soon become the first cryptocurrency airport terminal. The airport will partner with TravelbyBit, a cryptocurrency payment system, to allow travellers the ability to buy digitally.

The application of cryptocurrency will undoubtedly grow rapidly very soon. Travellers can travel around the world with a cryptocurrency wallet without limitations, so consider it before you take your next trip!

5G is the future

5G is the future

Nowadays, most people are phone-addicted. They are always on the phone, using social networks, gaming, chatting, movie streaming etc. The demand for mobile network usage is increasing, as users seek a fast, stable and secure network – 5G. 5G is the Next Generation

Mobile Networks and defines the following requirements:

  • Data rates of tens of megabits per second for tens of thousands of users
  • Data rates of 100 megabits per second for metropolitan areas
  • 1 Gb per second simultaneously to many workers on the same office floor
  • Several hundreds of thousands of simultaneous connections for wireless sensors
  • Spectral efficiency significantly enhanced compared to 4G
  • Improved Coverage
  • Signalling efficiency enhanced
  • Latency is reduced significantly compared to LTE

Major different between 3G, 4G and 5G








BY 2020






Broadband with / CDMA/ IP technology

Unified IP and seamless combination of LAN/ WAN/ WLAN/ PAN



Integrated high-quality audio, video and data

Dynamic information access, variable devices with all capabilities


Future of mobile network

2020 is the big year for 5G. According to the Ericsson Mobility Report, in 2020, there will be a reach of 9 billion mobile connections and 6.2 billion subscribers globally. 5 million of which will be 5G subscribers, covering a 15% of global population. 5G applications will make use of enhanced mobile broadband, mission-critical services and Internet of Things (IoT).

Development status:

The EU has decided to develop a 5G broadband network technology that uses the 694Mhz to the 790Mhz frequency band and major telecommunications service providers will be able to obtain usage rights by the end of June 2020.

The British government announced an updated 5G development strategic plan in December 2017. They strive to ensure 95% geographic mobile coverage and the availability of essential services where people live, work and travel. Also, they are developing a model to secure fast, reliable mobile connectivity on main rail routes and major roads. Some large and midsize businesses are paying for the trial of 5G high-speed networks.

In the US, Verizon Wireless, the nation's largest wireless carrier is co-operating with a South Korean based company, Samsung, to deploy and tested 5G in five cities across the United States. T-Mobile US Inc plans to launch 5G in 2019, and complete the nation-wide infrastructure rollout by 2020.

5G development in mainland China is led by the government and is part of the governments 'Made in China 2025' strategy. Three of the major network providers have announced their 5G implementation schedule, and are striving to achieve a goal to be 5G network ready by 2020.

KT Corporation, South Korea's largest telephone company, is working with Ericsson and local network suppliers to run a 5G network pilot testing during Winter Olympics in Pyeongchang, Gangwon-do, in 2018.

Japan Telecom operators, including NTT Docomo, KDDI and Softbank, will officially provide 5G communications technology services by 2020, while nationwide deployments are scheduled for 2023. The total investment will reach 5 trillion yen (about 45.7 billion US dollars).

Overall, the progress of 5G in 2017 has achieved gratifying results. We believe that in 2018, there will be a bigger breakthrough.

UK Local Sim Vs Roaming Sim

People always struggle when deciding which kinds of SIM card to use whilst travelling. Should you use your own SIM card and pay the roaming fee or buy a local SIM at the destination?

When you travel to the UK and buy a SIM card there, you will use the local rate. That’s what we call a “Local SIM”. The average price for data usage is €0.028/MB and €0.62/Min for a local call. Normally, the local rate should be better than roaming rate as the telecom providers provide the services to customers directly. What’s the difference? Let’s see.

Roaming in the UK

Different countries and suppliers will charge you at their own rate. And there a is huge difference between what they will charge you, versus what a local provider will charge you. Below is a summary of the roaming prices for  Asia, Africa, South America, North America and Oceania.

If you come from Asia, you will get the cheapest roaming rate. It is only cost you €0.13/MB for mobile data and €0.62/Min for a call (in UK to the UK). The second lowest region is Africa; it will cost you €0.16/MB of mobile data and €0.16/Min for a call (in UK to the UK). And the roaming price for Oceania SIM plans to the UK is 1MB mobile data or 1 minutes UK to the UK call for €0.33.

Unfortunately, if you are using a South America SIM plan and roaming in the UK, the price is much more expensive. The roaming data will cost you €8.89/MB and €1.21/Min for a call (in UK to the UK). It is 316% higher than using a local SIM for using mobile data.

But, this is not the most expensive. The roaming charge from a North America SIM plan to the UK is even higher. It is €12.77/MB and €1.27/Min for a call (in UK to the UK). For mobile data, it is 445% higher than using a local SIM. Can you imagine how terrifying it will be when you receive your phone bill after you return to your home country?

So why people are still using roaming?

A Brief History of the SIM Card

SIM cards are one of the many examples of hidden technology that enable our daily lives in the modern world. The majority of people need to only think about and see their SIM card for a few minutes each time they upgrade their phone. Here at SIM Local, we think about and see SIM cards more often than the average person! While we appreciate that not everyone shares our obsession, we’ve picked out some of the more interesting facts to share with you today.


Starting on an unexpected note, did you know that the Zimbabwean government abandoned its currency in 2009 due to hyperinflation? At its most extreme, prices were doubling almost daily, with the quickest doubling on record being 24.7 hours. In November 2008, the rate of inflation was calculated at a staggering 79,600,000,000% per month. So what has that got to do with the phone in your pocket? The German company Giesecke & Devrient, who printed these bank notes for Zimbabwe, are the same company who made the first SIM cards. They sold the first batch in 1991, a very modest order of 300 SIM cards in comparison to the billions which exist globally today.


So who bought these SIM cards? It won’t come as a big surprise to find that it was the technologically advanced Scandinavians. Radiolinja, a company in Finland, achieved a number of additional firsts in the mobile space during the nineties:


  • 1991: The world’s first GMS call was placed, which was the start of what is now billions of daily phone calls. Give Giesecke & Devrient and Radiolinja a thought the next time you’re forced to listen to “hello? I’m on the train. THE TRAIN.”
  • 1993: The first person-to-person SMS text message was sent, launching thumb Olympics amongst teenagers worldwide.
  • 1996: The world’s first fixed-mobile service bundle was launched.
  • 1998: The world’s first ringtone was sold. In our current world of in-app purchases, Netflix and Kindles, it’s strange to think that the industry of digital downloadable content didn’t exist until this first ringtone sale 17 years ago.


Another thing that has changed in the world of SIM cards is their size. Following most technology trends, over the years they have become simultaneously smaller and more powerful. The original SIM cards were the same size as a credit card. If you think back to the last time you bought a new SIM card, you might recall that it came embedded in a credit card sized piece of plastic. This is because new SIM cards are required to be compatible with older models of phones. While one of the original phones would be hard to track down today, theoretically you could install your entire credit card packaging with your modern SIM card still attached, and the phone would work. There’s something to remember if you ever find yourself in a Back to the Future scenario!

The Accidental Roamers

Typically when we think about roaming charges, what comes to mind is the unavoidable 10 minute call to your bank at home, or weighing up the decision to turn on roaming data to use Google Maps vs. wandering around lost for another hour. Roaming charges are expensive and unpleasant, there’s no doubt about that. However at least they’re made more palatable by the fact that you’re enjoying a nice holiday somewhere.

Not everybody has that luxury. For some people living close to their country’s border, roaming charges are an ongoing and daily nuisance.

One Canadian woman recently interviewed explained that she frequently receives messages from her telecom company warning that she has surpassed her $100 data roaming limit, without ever leaving her home town. According to, despite having a Canadian SIM card and living in Canada, her phone thinks that it is roaming in the United States.


Similar problems occur for owners of UK SIM cards in Northern Ireland. Ofcom, the UK telecoms regulator, estimates that in some parts of Northern Ireland, 30% of the population experience inadvertent roaming on a daily basis.

In these examples, the messaging from the network companies is fairly similar: while they empathise with the problem, the way our modern technology works can make the solution difficult. The radius of cellular towers doesn’t neatly follow borders, and two neighbouring towers from different countries can cause interference with one another. However as more regions, including European and African countries, are talking about eliminating or restricting international roaming charges, this problem may fade away over time.

So if you’re living or staying in a border region, is there anything that you can do to avoid expensive roaming charges? Luckily there are some solutions at hand.

    Firstly you can disable your phone’s ability to select a local wireless carrier, and manually lock it to your own contracted company.

    Secondly, you could consider buying an additional SIM card for your neighbouring country. Living close to a border opens up opportunities to very easily work, shop and socialise “abroad” so it’s possible that there’s a need to be in touch with both communities frequently. For example, people living near the border between Northern Ireland and the Republic of Ireland could buy both an Irish sim card and a UK sim card. You could buy either a second phone, such as a cheap unlocked mobile phone, and have two numbers on the go. Alternatively you could buy a dual SIM card phone which allows you to use two SIM cards simultaneously.

    Finally keep complaining! Just because you understand why the technology switches you between countries doesn’t mean that your problem is solved. Local networks still have a responsibility to avoid passing on these roaming charges to their customers. The more noise you make, the more seriously the problem will be taken.

      So what's a SIM Local when it's at home?

      This week we’ve launched our new website. We’ve been online for a couple of years, but it’s amazing how quickly things need to be refreshed and updated online. We decided to do a spring-clean of the appearance of the site, and also the cogs and wheels behind the scenes. With this in mind it seemed like perfect timing to launch our first blog.

      So what is SIM Local? To put it very simply, we’re a company who sells local SIM cards. We offer an alternative to expensive roaming charges, which gives our customers more money to spend on the fun stuff like sightseeing, shopping, shows, sporting events and supper. 

      The SIM Local team is based in two countries. We have a large team running our 3 stores in Heathrow airport, and the rest of us are split between our Dublin airport store and our head office just outside of Dublin city. We have some things in common with our typical customers. We love to travel, and are glued to our phones. We’ll be writing about interesting travel or mobile stories that we come across, or our favourite bugbear, roaming charges. The blog will also be a source of news for any new products, partnerships or store openings that we’re planning.

      We’re also active on Twitter and Facebook, so don’t be shy about getting in touch. We also welcome emails to

       We have a few things up our sleeves in the coming months so come back to catch up with us!
