eSIMs are gaining fast popularity, with several of the latest iPhones and Android models supporting this new GSM specification. We’ll cover everything you need to know about how to use eSIM with a mobile network, and how to find out if your device is compatible. An eSIM (embedded SIM) is a virtual SIM which you can install on your phone as software, removing the need for a physical SIM. For it to work, your phone must have a built-in “eUICC chip.” This chip, embedded by the manufacturer, is programmed with an eSIM ID (EID). It further connects to your carrier using an “eSIM profile,” providing the same voice, text, and data services as a physical SIM. You can use multiple profiles depending on your phone’s specifications. For example, an eSIM-compatible iPhone allows 8 or more profiles, and the latest Samsung Galaxy devices allow up to 20. However, like actual SIMs, you can’t use more than two active eSIMs at the same time. Since the eSIM is embedded directly into your phone, you can’t physically remove it from the device. However, just like a swappable SIM card, you can change it to a different network (if it’s not locked, that is). eSIMs are rewritable. That means you can change networks without removing your SIM. However, you will have to erase the existing eSIM profile and activate the new one. Like mini SIMs, micro SIMs, or nano SIMs , even eSIMs have their standardized physical form factor, called MFF2 (Miniaturized Form Factor 2.) While both eSIM and physical SIM provide the same functionality, they differ in a number of ways: To understand who can use eSIMs, check the following. As a general rule, you should verify each device’s specifications individually. Since eSIM technology only became mainstream after 2018, any handset models older than that would not be supported. Even for the latest phones as of 2024, many may not have eSIM compatibility. However, many newest iPhone devices in the U.S. have switched to an eSIM only configuration. To check if your phone supports eSIM, try the following methods: Currently, the following devices are having confirmed eSIM support. Other phone brands including OnePlus, Motorola, and Xiaomi have also launched eSIM compatible models. Apart from the phone device maker, your telecom operator should also support eSIM. In the US, all leading carriers including AT&T, T-Mobile USA, Verizon Wireless, Truphone, Ubigi, and Visible support eSIM. Globally, a large number of telecom operators in different countries have eSIM support with prominent exceptions being Mainland China, and a few others.

If you want to know how to use eSIM on your device, your device compatibility plays a crucial role. If both your device and carrier support eSIMs, use the first method. Otherwise, choose the second method. The great advantage with eSIM is that, unlike in the case of a physical SIM, you don’t need to visit a store or put in a mail order for a new SIM card. Using what’s called “remote SIM provisioning,” network providers can beam details to your eSIM, allowing it to connect to their network. The steps to activate an eSIM vary slightly depending on the mobile operator and device. In my case, I can use SMS-based activation with my carrier for a quick SIM upgrade to eSIM. All I need to do is give my consent, which will disable the physical SIM and activate the eSIM. There are other ways to switch from a physical SIM to an eSIM. Some telecom operators encourage you to complete the change through their mobile apps, which makes the process straightforward. Alternatively, the mobile operator might provide a QR code containing the eSIM profile that you can scan with your phone. Related : learn how to change your SIM PIN on Android and iPhones. If your Android phone is not eSIM compatible, there’s a workaround. You can order an eSIM adapter, which is like a tiny SIM card that fits into your physical card slot. The eSIM adapter comes with a prepaid data package for a specific country, which you can recharge as needed. This hassle-free method is popular among digital nomads and other travelers. Before placing your order, make sure your phone is compatible with the eSIM adapter. I checked a popular service called eSIM.me . It diagnosed my device and confirmed they had an adapter for it. Most of these plans are prepaid. After purchasing one, a QR code is sent via email on your intended delivery date (when you travel to a new country). You simply need to scan the code with your phone to use eSIM services on your device. Follow the instructions for uploading the eSIM profile on your phone which may require a device reboot. aloSIM is another popular eSIM adapter service that is very popular with travelers. Some of the top advantages of eSIM cards are: There are a few disadvantages of eSIM which is slowing its adoption among end users: We have explored how to use eSIM on your device. In addition to mobile phones, smartwatches like Apple Watch Series 3 and above, Samsung Galaxy watches, and many computers also include eSIM technology. Apart from that, other IoT products like cars, smart meters, security systems, etc., can also support eSIM. A carrier’s both new and existing users can apply for eSIM. On the other hand, more and more phones offer dual SIM functionality these days with one SIM as an eSIM. With eSIMs in place, you can also access Android phones with broken screens .

President-elect Donald Trump’s election victory has led the Kremlin to double down on a risky gamble: that Trump’s desire for a quick resolution to the war in Ukraine will lead to a settlement that freezes the conflict along its current lines, legitimizing Moscow’s territorial gains. Since the US election, Russian forces have ramped up their military offensive, which will predictably continue until the inauguration as Russian President Vladimir Putin aims to strengthen his negotiating position. Despite Europe’s wish for stability on its eastern border, it must not accept any resolution that entrenches Russian territorial gains in Ukraine. Indeed, several indicators suggest that the war may be entering its final stretch. The course set by Moscow might be leading it toward an iceberg over the next twelve to eighteen months, as Russia confronts three primary challenges that could alter the conflict’s trajectory to the Kremlin’s disadvantage. First, the Russian economy is under severe strain from the war’s financial demands. Military wages have skyrocketed , with new recruits offered substantial sums, distorting the labor market and creating a stark wage gap between military personnel and civilians. The average civilian salary is currently at just above a million rubles per year, while many new military recruits receive a sign-up offer of up to two million rubles. This unsustainable policy, designed to increase recruitment and maintain morale, is destabilizing the economy by distorting the labor market. It is also a testament to Putin’s miscalculated gamble on a swift military campaign. To sustain the war effort into its third year, Putin is now dragging the Russian economy toward a crisis due to escalating military expenditures. Second, Russian manpower shortages are becoming critical, with an estimated thirty-six thousand soldiers killed or wounded each month. Recruitment quotas are stretched thin, with regions throughout Russia struggling to feed the country’s war machine with men. To ease the pressure, Russia has begun recruiting from territories it occupies in Ukraine and has even resorted to turning to North Korea for additional troops to avoid tapping into the populations of Moscow and St. Petersburg. The deployment of troops from Pyongyang is unlikely to be a one-time occurrence. Instead, the Kremlin appears to be trying to establish a pipeline of ten thousand to fifteen thousand North Korean troops per month to fill its manpower deficit and try to stave off an eventual crisis of manpower shortages. Third, Russian forces are facing a looming crisis in heavy armored vehicles as stocks dwindle. The scarcity of such equipment will eventually force a shift toward more infantry-intensive tactics, likely causing further increases in Russian casualties. Putin’s intensified military efforts in anticipation of the US election were a calculated risk, betting on a quick settlement. However, if Western resolve holds over the next twelve to eighteen months—when Russia might hit its breaking point—the conflict’s outcome could defy Putin’s expectations. The importance of Europe sticking together Europe will likely become a lower priority for the United States in a second Trump administration, as Washington’s focus and resources shift toward China and the Indo-Pacific. This pivot will put more pressure on European states to strengthen their defense spending, increase their contributions to NATO, and move toward greater strategic autonomy. As this shift gives the United States greater flexibility in Asia, it will also require Europe to take greater responsibility for addressing regional security challenges, such as the threat posed by Russia. It is possible that US disengagement from Europe, combined with Russian advances in Ukraine, might convince European Union (EU) countries to agree to a robust common European Defense. But a Russian victory would likely end up undermining Europe’s ambitions to become a more cohesive political bloc. Although Ukraine is not an EU member, a Ukrainian defeat could spill over and end up revealing that the bloc is not prepared to fulfill the most basic mandate for any political entity: guaranteeing strategic security and stability to its citizens. One plausible reaction to a Ukrainian defeat would be for major European countries to retrench into their own state-level security, which could then threaten to weaken the European project along its economic and other lines as well. Moscow is deeply aware of this and plans to realize this prospect through hybrid campaigns, including weaponized immigration, arson, sabotage, cyberattacks, and disinformation. Arguably, the primary effort of Russia’s war is not the kinetic one on the battlefield, but rather the cognitive one directed at European countries to undermine their political will to act, making a Russian victory inevitable, so the Kremlin hopes. Peace isn’t peace if it leads to another Russian push If the United States reduces its support for Kyiv, then Europe must resist the temptation to seek a premature, unjust settlement. What may appear to be the restoration of peace would cause catastrophic damage to the West’s deterrence. It would also be a welcome respite for Putin, allowing him to reorganize and prepare for a new push toward the Kremlin’s repeatedly stated objective of erasing Ukraine as an independent country. Many indicators suggest that the war is entering a decisive stretch, presenting a crossroads for Europe’s future. With the United States potentially reducing its commitment to Ukraine and the new European Commission taking charge in Brussels, the EU’s actions vis-a-vis Ukraine will be carefully watched by allies and adversaries as the first signs of its new strategic identity. They will shape its perception in Washington as well as in Moscow and Beijing—whether it be one of division or unity, strength or weakness, awareness or denial. As Russia sails toward the iceberg, it is crucial for Europe to remain steadfast in its stance. Allowing Russia to claim victory now would not only have grave consequences for Ukraine but could also lead to the collapse of the European project.
