Here’s what you need to know about eSIM

The technology behind Apple’s first dual-SIM iPhone

Published

on

When Apple first revealed their new iPhone XS and iPhone XS Max, people were expecting something different. While on the outside nothing seems to have changed, the inside is a whole different story. The most notable change is the introduction of eSIM (embedded SIM) technology, something that they’ve done before with the Apple Watch.

But, what is this eSIM? How different is it from the SIM card that you know and love? And does using an eSIM change the game completely?

Let’s talk about the SIM and eSIM

One of the essentials for any phone in the market is a SIM card. Short for Subscriber Identity Module, a SIM card contains key identification and security features from any network carrier. It is used by these networks to identify their consumers and provide mobile connectivity for them — through calls, texts, and access to the internet. SIM cards also allow you to store information when you decide to switch devices every now and then.

eSIM technology, as the name implies, is embedded into the phone yet it still keeps the same functionalities as before. On devices that were designed with only one SIM card slot, adding an eSIM makes it a virtual dual-SIM machine. 

How have regions adopted eSIM?

As mentioned earlier, this isn’t the first time Apple dealt with eSIM tech. The company had initially launched the eSIM for their Apple Watch Series 3 to give it better connectivity on the go. While Apples continues to incorporate eSIM in its newer Watch Series 4, they’ve decided to take it one step further with the iPhone XS and iPhone XS Max.

However, as of writing, only ten countries in the entire world currently support eSIM. This is mostly due to these countries having the proper infrastructure to support the use of it. While smartphone companies are looking to incorporate this new technology, the market for it seems to be relatively small.

The good and bad about eSIM

Like any other new technology, eSIM comes with its own set of benefits and difficulties — especially for those transitioning from the traditional SIM card. With eSIM installed in your phone, users will no longer have to go through the hassle of buying a specific SIM card.

Ideally, having an eSIM also allows you to switch between networks easily. Apart from an eSIM-capable phone, it also comes with the needed software to make the switching process faster and easier. In essence, you will be able to free up the allocated SIM card slot for a physical SIM card if your device supports it. This is most helpful when you travel abroad, and you need a local number in that country to access their network.

However, there are some processes that prove to be difficult with eSIM, one of which is quickly transferring your phone number to another phone, especially if you frequently switch devices. Unlike traditional SIM cards wherein you just transfer the card, you’d have to contact your service provider to activate the number in your new phone. This could be cumbersome depending on your provider’s customer service.

Furthermore, if the eSIM in your phone becomes corrupted or gets damaged in any way, it’s possible that you would need to replace your whole phone. Because the eSIM is integrated inside your phone, it won’t be easy to pry it out when things go wrong. This wouldn’t be too big of a concern for traditional SIM cards, especially when the card gets destroyed.

Are smartphones ready for the eSIM?

The eSIM technology is still in its young stages, and only a handful of devices currently support it. There is potential for the tech to be implemented across more devices in the future despite only a few countries welcoming them. However, a lot of people still primarily utilize traditional SIM cards given the difficulties of using an eSIM.

In the case of the new iPhones, for example, you can’t create two instances of chat apps on iOS. So even if you have two numbers running at the same time, you’d need a separate phone for another WhatsApp or Viber number, until Apple comes up with a software patch for this.

In the end, the technology’s impact can only be measured once more devices embrace it. But, for now, let’s celebrate how the eSIM gave us the first dual-SIM iPhone and see where the future will take us.

Here’s how India is trying to be China in the smartphone game

The world’s second-largest smartphone market has more to offer

Published

on

China is practically the world’s production powerhouse. And India wants to follow the same path. India’s Central government has approved three schemes to enable large scale electronics manufacturing and attract fresh investments worth almost INR 50,000 crore (US$ 6.3 billion) in the sector.

The government aims to provide companies a production-linked incentive of 4 percent to 6 percent on incremental sales for locally made goods over a period of five years. This not only includes mobile phone manufacturing but also assembly, testing, marking and packaging.

The other policy offers a 25 percent financial incentive for capital expenditure that goes towards “the manufacturing of goods that constitute the supply chain of an electronic product”. With these incentives, the government is optimistic that companies will come to India, contribute to progressing infrastructure, and make export-quality goods.

Inauguration of Samsung’s Noida Factory in India

According to their estimates, domestic value addition for mobile phones is expected to witness 35 to 40 percent jump by 2025, from the current 20-25 percent.

So far, companies have focused on assembling equipment like smartphones in India. A huge chunk of the components are still imported. These policy changes could act as a stimulant to locally source electrical components, semiconductors, as well as develop production clusters.

Bangalore and Hyderabad are infamous for their IT Tech Parks that house thousands of employees from IT service firms like TCS, Infosys, Accenture, and many more. Similarly, the government wants to create production clusters that can develop an eco-system of their own. These clusters can create a seamless supply chain when paired with proper land, air, and shipment infrastructure.

The timing of the announcement is what matters the most. China is embroiled in a trade war with the US for quite some time and we’ve seen how a giant like Huawei got caught in the cross-fire. Companies are skeptical about depending too much on China for production and sourcing. Hence, countries like Vietnam have witnessed a huge inflow of foreign investment from the likes of Nintendo, Foxconn, and even Samsung.

India is very much like Vietnam. A developing economy that’s on the look-out for foreign investment and enhances local production capabilities. This not only helps the government increase its tax revenue via taxation, but also provides employment. Considering the current Coronavirus crisis, it’s obvious that these plans may not materialize soon. But, as soon as the storm is gone, companies would want to find an alternative to China.

Prime Minister, Narendra Modi with Apple CEO, Time Cook

It’s reported that the alleged low-cost iPhone from Apple has been delayed due to the pandemic. Irrespective of the current health crisis, Apple has been trying to ramp up its local production in India and has done so, cautiously. India is the world’s second-largest smartphone market and every brand wants a piece of the cake. Realme and Xiaomi have been intensely fighting for supremacy, Samsung continues to lead via the offline market, and OPPO and Vivo have flooded all commercial banners with their products.

Xiaomi currently has seven plants in India, major ones being at Sri City and Sriperumbedur. It also makes its televisions in Tirupathi. Manu Kumar Jain, Vice President, Xiaomi, and Managing Director, Xiaomi India said that 95 percent of Xiaomi’s phones are made in India with 65 percent of a phone’s value being sourced locally. The government has been successful in compelling companies to make in India because it consistently kept on raising import duty on smartphones.

Samsung already has the world’s largest mobile phone factory in India that assembles top-tier variants, ready for export. We don’t know the volume it churns out right now, but their long-term investment is a precedent for other brands to take the market seriously. OnePlus has a research facility in Hyderabad where it makes software products intended for the Indian market.

Samsung’s factory in Noida, India

According to industry ICEA, the NOIDA region (a part of Delhi NCR) has close to 80 mobile manufacturing factories that provide employment to approximately 50,000 people. It’s normal today to see companies release press notes announcing new facilities across the country that’ll employ thousands of people.

Prime Minister Narendra Modi kickstarted the “Make in India” campaign five years ago to encourage foreign companies to invest and build in India. While its effects are debatable in a few industries, there’s no doubt that the mobile industry has picked up exponentially. State governments of Karnataka, Andhra Pradesh, Telangana, Uttar Pradesh, and Tamil Nadu have played a major role in establishing these clusters that symbolize progress.

Engineers are widely available in India, the country has developed multiple ports under the private-public model, and numerous airports are under construction. India is already the world’s second-largest smartphone maker, but the gap is huge. It’s about briding this. Obviously, the scale at which China produces is unmatchable. But that cannot undermine India’s efforts to be more relevant on the global stage. From a purely consumption-based economy, it’s slowly trying to turning into a production backed state.

Explaining smartphone display refresh rates

Are they really any different from PC displays?

Published

on

Smartphones, little by little, are turning into mini-PCs with the features that come with it. From browsing on social media to playing video games, technology is slowly adopting a more “on-the-go” lifestyle. Recently, smartphones have acquired another feature that your own desktop or laptop already has.

Some of the recently released premium and gaming smartphones now come with displays having their own dedicated refresh rate. Refresh rates aren’t new, but to see it on a compact device has a lot of people wondering. How different or similar is it to a PC’s refresh rate? And is it actually something good to have?

A crash course on refresh rates

A display’s refresh rate, basically is the number of times your display updates every second. Your screen usually takes a few seconds to just a second to load new images, depending on that rate. For example, a 60Hz refresh rate means that in one second, any image on your display is refreshed 60 times. Your eyes wouldn’t catch it fast enough, but that’s how your display works.

For most PC displays, the default is at 60Hz with companies releasing displays that range up to 240Hz. You mostly see this in displays fit for gaming purposes, since gamers prefer the higher refresh rate for improved performance. If you’re someone who mostly likes to watch movies, it really doesn’t matter how high the refresh rate is.

Note that this is entirely different from frame rates, in that these show how many images are produced within a second. Although, having a high refresh rate allows you to perform a lot better because it is optimized for higher frame rates. That’s why you see some gamers complain about playing on a 60Hz display.

Transitioning to a smartphone near you

Eventually, the concept of amping up a refresh rate will reach the world of smartphones. In fact, the OnePlus 7 Pro was actually the first mainstream smartphone to have a display with a 90Hz refresh rate. Most smartphones, even budget ones, have displays built with a 60Hz refresh rate. Something about it just makes you scroll through your phone without feeling too dizzy, unless you scroll too fast.

Premium smartphones mostly incorporate either a 90Hz or 120Hz refresh rate for a smoother UI experience. With higher refresh rates, scrolling through your phone feels a lot smoother without risking an eye sore. Of course, these smartphones do cost significantly more than your average, everyday smartphone.

Apart from premium smartphones, gaming smartphones have also incorporated higher than 60Hz refresh rates. Phones like the Razer Phone 2 and the ASUS ROG Phone 2 both come with a 120Hz refresh rate to suit mobile gamers, especially FPS (first-person shooter) gamers. With these higher refresh rates, mobile gamers see clearer images with less motion blur involved.

Do you really need all the hertz?

That begs the question: what do you need a high refresh rate screen for? When you use a PC, 60Hz is already good for most tasks and games. Trying to go for higher refresh rates usually means that you’re doing a lot more than the ordinary. Tasks such as heavy-duty data analytics or hardcore gaming are optimal for higher refresh rates.

The same logic works for smartphone displays, except on a smaller screen size. A lot of what you can do, you’re able to do so on 60Hz displays. If you’re just using your phone to browse social media, watch Netflix on the daily, and play games casually, you don’t need anything higher. Although, it is a premium to have if you want buttery smooth software.

If you play games competitively, you would prefer higher refresh rates just like in gaming monitors. Higher refresh rates allow you to perform at an optimal level when going for higher frame rates. We’re talking close to no image tearing or motion blur when you play PUBG Mobile or Call of Duty. While you can perform well at the default 60Hz, going for a 90Hz or 120Hz ideally makes the experience better.

Some final thoughts

Smartphone display refresh rates have always been a part of the technology. These displays were built in a way that everyone can benefit from them. It’s only fairly recently that smartphone companies came up with a way to make the experience a lot smoother. Hence, smartphones started incorporating higher refresh rates.

It almost feels like having that high refresh rate is a premium, given only select smartphones have it. But it’s a premium that you don’t really need unless you have a good reason to. Apart from the cost of experiencing it, it really depends on what you plan to do with your smartphone.

At the end of the day, it’s better to ask yourself if it’s a feature worth getting. If it’s something you feel you can’t live without, by all means, right?

Stranger Things 3: What exactly is an ignition cable?

Possessed Billy knew what he was doing

Published

on

By now, you’ve probably seen the third and newest season of Stranger Things on Netflix. If you still haven’t, it goes without saying that there are spoilers ahead and you should stay away from this article.

Seeing a pop culture reference such as Stranger Things together with the seemingly unrelated world of automotive in one writeup such as this could be strange (pun intended) for some. We really don’t mind and thought it would be a fun and unique way to talk about the show and learn a few things from it, as well.

So we ask the question: What exactly is an ignition cable?

The ignition cable is part of a vehicle’s ignition system. In simplest terms, it’s a mechanism that starts the engine. By generating a high voltage from the car’s battery to the spark plugs in its engine, it causes them to ignite the engine’s combustion chambers and get it up and running.

And in order to transfer that voltage from the source to the engine, you’ll need an ignition cable as it’s like a subway system that acts as pathways for the voltage to pass through. So if the ignition cable is not present, there’s no way to start the car.

Back to Stranger Things, Billy (although already possessed by the Mind Flayer) obviously still had his knowledge on cars so he took away the ignition cable trapping our favorite gang at Starcourt Mall’s parking lot.

Just to further stress the importance of an ignition cable and the whole ignition system for that matter, we’d like to visit other possibilities and ask, “What if Billy didn’t take it away?”

Well, the plan was for Eleven and her group to go to Bauman’s secret place and stay safe while Joyce, Hopper, and the rest try to close the portal and render the Mind Flayer powerless. If their ignition cable was intact, they’d be a lot safer away from the Mind Flayer although we wouldn’t be able to see that amazing fireworks scene inside the mall.

Through this, we see the importance of that one small part under the hood of the car. In real life, it really pays to make sure that everything is in good working condition and that one faulty cable could mean trouble for you if remained unaddressed — unless there’s a car on display inside a mall somewhere that you can take spare parts from!
