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.

Back in the earlier days of the internet, an emerging but short-lived trend involved chatbots who could generate conversation with whomever it talked to. Does this sound familiar? Today, a similar phenomenon is creating a lot of waves online, headed by the infamous ChatGPT. The exceedingly popular ChatGPT is turning heads out of fear that the technology will eventually upend society and eradicate a lot of jobs.
But what exactly is ChatGPT? How is it different from language programs in the past? Is the world right to worry about them?
On the rise of language learning
ChatGPT is hardly the first software to inexplicably generate comprehensible dialogue without human intervention. Decades ago, the internet hosted rudimentary versions of today’s chatbot technology. The concept is somewhat similar, though. The early versions relied on a database of responses from human users. If you asked about coffee, for example, the answer you get will likely come from the logs of another user who talked about coffee in the past.
Because the system was imperfect in its infancy, part of the appeal was trying to get the software to fumble a conversation. However, if it did mess up, you can count on it asking you what it should have said. The next time someone asks the same question, the software might mirror what you said, creating a learning process between the software and the user.
Today, chatbots — meaning those usually used by businesses today — operate in the same way. If a customer comes with a query, the software will rely on a set of responses to most appropriately address the user’s problem. If the software can’t come up with a solution, the ball usually gets passed on to a human consultant.
Is ChatGPT just another chatbot?
Though the label certainly gets thrown around, ChatGPT isn’t strictly a chatbot. Instead, the software uses GPT-3.5, a specific language model created by OpenAI. Whereas early and more rudimentary versions of the same technology can already store an unbelievable amount of information in its memory, ChatGPT can analyze billions of words and the relationship between them.
Further, OpenAI extensively trains the software, ensuring that comprehension and grammar can live up to today’s standards. The learning is supervised. In fact, the company even has a makeshift reward system to ensure that the software puts out the most appropriate response. With users also contributing to the software’s learning process, ChatGPT is quickly emerging as a powerhouse for the technology.
The results speak for themselves. While users can generate simple conversations with the software, ChatGPT can just as easily answer more extensive queries with lengthier responses. If you ask it to create an essay about Christopher Columbus, for example, it can write a lengthy piece that can easily fool a casual reader. It can even handle more speculative queries. In a sample published by the developer, ChatGPT can answer what would happen if Columbus discovered America in 2015.
What’s it good for?
Based solely on what the software can do, ChatGPT can find its purpose in today’s world. The software can improve voice assistants and chatbots all over the internet. It can make big strides in the world of automation, enabling a more responsive interface between user and software.
On a more human aspect, the software can also handle more professional jobs with simpler prompts such as those involving simple marketing copy. It can help with more ephemeral research efforts, allowing users to get simple answers for otherwise complex questions.
And, on a more technical side, ChatGPT can reportedly analyze and detect what’s wrong with a piece of coding. With the software, developers can use ChatGPT to potentially repair code without having to pore over every single line. Allowing a powerful tool to inspect code speaks volumes for a lot of applications all over the world including smart vehicles and technical machinery.
However, as with every piece of technology, users will always find a way to use something beyond what it was originally designed for. ChatGPT is now changing the world of education as students are using the software to do their homework for them. Though a lot of the sample texts look like they can fool only lower levels of education, a Wharton business school professor (via Business Insider) recently stated that he would have been fooled by a ChatGPT essay, grading a sample with a passable grade of B or B-.
Should we be scared of ChatGPT?
ChatGPT is undoubtedly rocking the world of education. While some schools have banned the technology outright, others are debating on the software’s impact on how schools are taught. Since ChatGPT deals out more factual information, could education reinvent itself to teach more personal, tailored learning, rather than just the ability to spit out memorized facts. (“Factual” might even be an exaggeration. CNET, which recently experimented with AI-written articles, discovered a plethora of errors from using the software.)
Now, education isn’t the only world in peril. The creative industry is facing an extreme challenge wherein ChatGPT can potentially cause workers their jobs. Though the danger certainly seems real, the limitations of technology are also real. ChatGPT can create comprehensible text that can fool a human, but it will likely stumble with conceptualization.
A piece of software is just software. Even if it can write an essay about existentialism, it cannot think of the concept metaphysically. In the same way, even if it can show you a photo of a parrot, it cannot think of that photo as anything but a pattern of pixels. To a language learning software, words don’t mean anything else besides their relationship with each other. It’s the same thought process as a dog learning to run to its human when its name is called. The dog doesn’t know that you just said its name (or even the mere concept of a name); it just knows to do a certain action after hearing a specific sound.
Can ChatGPT change the world? Overall, the jury is still out, but it’s unlikely that a piece of learning software can do much to replace human-centric work. Regardless, it’s important to think of how ChatGPT can improve (or detriment) humanity.
Like with other supposedly dangerous technology, the world of technology is a Pandora’s box. We can never put the genie back into the bottle. Once it’s out, it’s out. Instead of worrying about how technology can destroy the world, the more appropriate response is to figure out how it can better humanity without sacrificing anyone’s wellbeing in the process.

If you watched the latest Far Out event from Apple, you might have noticed the debut of a new technology coming to smartphones: satellite connectivity. Though Apple has made the biggest deal of the new feature, the technology has existed even before Apple’s announcement. In fact, various smartphone makers are also announcing their own takes to go along with Apple’s satellites.
But what exactly is satellite connectivity? Before the world gets more of the new feature, let’s take a look at this emerging technology.
Look at the sky
The night sky is filled with satellites. Though you might not see any of them with the naked eye, they are all there in low Earth orbit (LEO). As you might imagine, their uses are aplenty. Most attribute LEO satellites to imaging, navigating, and measuring data. However, one emerging use is the improvement of connectivity for consumer devices.
Now, the biggest proponent of satellite internet is Starlink, a project of Elon Musk’s SpaceX. With over 300,000 satellites, the company’s satellite constellation provides internet to several countries including areas with low coverage. In fact, the company’s services are already somewhat in the Philippines.
Satellite internet does have its benefits. While the service isn’t the fastest, it offers connectivity that regular towers can’t normally reach. Imagine being out on a hike but you suddenly remember, oh my God, you left your stove running at home. Satellite internet will allow you to connect to the internet and notify a neighbor to check if your apartment has any wayward burn marks running up its walls.
Quite a feat, isn’t it? But is this what Apple just launched?
SOS, please someone help me
Contrary to what you might think, Apple’s new satellite connectivity doesn’t offer internet. It’s also not Starlink. Instead, it’s a simple SOS messaging service through the Globalstar satellite constellation. It won’t solve your faulty 5G service. However, it’ll help you in a pinch if you find yourself lost in the middle of nowhere.
Once again, imagine you’re out hiking. Suddenly, you fall down an unseen slope and break your ankle. You find yourself miles and miles away from civilization, and no one knows where you are. Apple’s satellite connectivity can help you send an SOS message to the authorities.
Here’s how it works. When you’re in a predicament, fire up the feature and point your phone towards the satellite nearest you. (Don’t worry; the phone will tell you where it is).
Now, it might take a few seconds to a minute before the phone can connect to a satellite — especially if the skies aren’t clear or if you’re underneath a canopy of trees. It might not even connect if the skies are completely obstructed. Regardless, while it tries to connect, the phone will ask a series of questions including who needs help and if anyone was harmed. This helps the phone craft and compress the necessary information for your message.
Because the service is only for emergencies, you can’t write an essay. Apple says that it will squeeze messages three time as small to ease transmission. It’s a wide-reaching 911 call for when you can’t actually call 911.
After compressing the message, the satellite will then beam the message to a nearby relay station on the ground, which will alert authorities for you.
Who can use it?
Naturally, only Apple users who have the latest devices will have the feature for now. Also, because it’s so new, it’s only coming to the United States and Canada with the upcoming iOS 16 update later this year. Of course, it might arrive to other territories soon after the initial launch.
China, however, is a no-go. Huawei launched its own satellite connectivity, packing the feature in the new Mate 50 series. If you’re in mainland China, you’ll have to use Huawei’s services.
Interestingly, Apple made it a point to say that the feature is free for the next two years. The implication seems clear: Users might have to fork over cash to keep the feature once the two years are up. Now, if you’re celebrating the coming of this arguably essential feature, the possibility of a paywall might leave a sour taste in your mouth. Should companies gatekeep who gets to send emergency messages in their time of need?
Passing fad or the future?
If you’re not a regular hiker, satellite connectivity might not appeal to you. However, it’s still interesting to wonder if the technology will make an impact outside of Apple. And it does seem that way.
It’s no coincidence that a few brands, including Apple and Huawei, have suddenly launched their own satellite connectivity features within a short span. Companies are putting a lot of money into the future of satellites. Very likely, Apple won’t be the last company to adopt the new feature.
Emergency satellite services are essential. Even if you don’t hike, you’ll never know when you might get into a precarious situation without cell coverage. Satellite connectivity mitigates that risk.
Now, how will the technology evolve beyond emergency services? Coupled with the efforts of Starlink, the early stages of satellite connectivity proves the concept of a satellite-laden future. Currently, a lot of services still struggle with the lack of towers in certain locations. The aid of satellites creates a future that won’t need towers everywhere. Though speed might be an issue, connectivity won’t.
That future is quite a possibility. However, it will also come with a host of questions. With space limited to only a handful of providers, will companies launch more satellites to address the potential need? How will space look like then? Will it just be a wasteland of used satellites? How much will everything cost? Though it’s coming, the future still has much to clarify.
