Physical SIM Card vs. eSIM: What Sets Them Apart and Which Should You Choose?
For many years, mobile phones received cellular service through a physical SIM (subscriber identity module) card that connected your handset to your phone carrier. These physical SIM cards made it easy to swap your phone or carrier whenever you're getting a new device or you're traveling. Nowadays, however, most modern phones also support eSIMs. As the name indicates, eSIMs are embedded directly into the phone and the carrier information is programmed remotely via software. Whether you choose a physical SIM or an eSIM depends on several factors, so we've outlined a few commonly asked questions below. An eSIM lets you set up wireless service using software, instead of a physical SIM card. Apple/Screenshot by Sarah Lord/CNET What do physical SIMs and eSIMs do? A physical SIM card is essentially a tiny card with a chip that connects your phone to your wireless carrier. It contains identifying information like your account info and phone number. Without it, your phone won't have a number or any way to connect to a carrier and you won't be able to make or receive calls and text messages. Some phones allow you to remove the physical SIM card, which allows you to easily swap phones or carriers. This is useful if you want to use your existing number in another phone, or if you want to use your phone with another carrier. Just insert a different SIM card and you can connect to a different cell network. For years, some phones supported having dual SIM cards. You might have your home number on one and your work number on the other. An eSIM, however, is embedded directly into the phone's circuitry and cannot be ejected or removed. Instead, all the carrier information is programmed remotely via an app. The biggest advantage of eSIMs is that it allows one phone to have multiple lines even from different carriers. This is especially useful when traveling, as you can add a global eSIM provider without having to purchase and wait in line for a physical SIM when you arrive at your destination. For more on eSIMs, you can check out our explainer here. You can also move your service from one phone to another without needing to dig out a SIM ejector tool but you might need to call your wireless service provider for assistance. Many phones still use physical SIM cards as an option alongside eSIM. Jason Cipriani/CNET Can I have an eSIM and a physical SIM? Yes, many phones allow you to have an eSIM and a physical SIM simultaneously, even from different carriers. You can use both simultaneously, or you can designate one as active while the other is on standby. Some people designate one number for work while the other is for personal use. How do I switch phones with a physical SIM or an eSIM? To switch phones with a physical SIM, all you have to do is eject it from your existing phone and then insert it into a new one. This typically works regardless of the phone you are switching between, allowing you to move your service from an iPhone to Android phone at will. With an eSIM, your carrier can either transfer the number over for you or you can do it yourself through your phone's settings. Your carrier will often send detailed instructions on how to do so. Typically it's easy to transfer your eSIM when moving to a phone of the same operating system, for instance moving from an iPhone 14 to an iPhone 16 where both are on iOS or from a Samsung Galaxy S21 to an S25 because both use Android. If you are switching between iOS and Android, you'll likely need to call your provider for assistance. Converting an existing physical SIM card to an eSIM is fairly easy too, although it sometimes requires more steps. You can check out our guide on how to do so here or you can refer to your carrier for more specific instructions. In the US, all iPhone models since the iPhone 14 require eSIM. Internationally, Apple still includes a physical SIM slot. Celso Bulgatti/CNET Do any phones require eSIM? Yes, some phones are eSIM-only and therefore require eSIM. iPhone 14 models and newer are eSIM-only in the US, meaning they lack a physical SIM card slot. Most Android phones include a physical SIM slot and support for eSIM. Simpler phones, like the Barbie Phone made by HMD, only use physical SIM cards. HMD Do all phones accept eSIM? Most modern iOS and Android phones accept eSIM, such as the newer iPhones, the Pixel 6 and the Samsung Galaxy S21 and newer. Simpler phones, however, like HMD's Barbie Phone and the minimalist Light Phone do not. For those phones, you'll want a physical SIM card.

T-Mobile explains to the FCC why it couldn't have interfered with NextWave's 2.5GHz signals
A little over a year ago, we told you that NextWave, a company that offers secure and reliable mobile broadband via a private network to industrial and enterprise users, was having a beef with T-Mobile . NextWave controls 2.5 GHz spectrum (Band 41) in several major cities, including New York City. As many long-time PhoneArena readers know, this is the same frequency used by T-Mobile for its mid-band 5G service and is one of the reasons why the carrier is considered to be the top 5G provider in the U.S. T-Mobile has unleashed a new argument in this battle with the FCC and NextWave. In a filing submitted to the regulatory agency, T-Mobile says that if NextWave has no customers, it doesn't matter if it is operating within NextWave's spectrum range. According to T-Mobile , NextWave has not shown that it has built the facilities and is providing service to customers in the areas where it has been accused by NextWave of exceeding signal strength limits mentioned in the rules. As a result, T-Mobile says, "There is no basis for NextWave's continued complaints [about T-Mobile interfering with its signal]. NextWave offers 5G private networks using 2.5 GHz 5G mid-band spectrum. | Image credit-NextWave Getting even more to the point, the nation's second-largest wireless carrier told the FCC, "If there are no customers to serve, there can be no 'service' requiring a reduction in power." NextWave has a different take on this, of course, and earlier this month it reminded the FCC that the agency's role includes policing spectrum and dealing with interference. In this case, both go hand in hand. NextWave almost scolded the agency by saying, "Given the duration, severity and willful nature of T-Mobile 's misconduct for more than two years, it is now imperative for the commission to perform these duties ... and demand that T-Mobile immediately cease its unlawful operations." And while the FCC did issue the aforementioned two violation notices to T-Mobile , the latter says that it no longer needs to take any action at all. Replying to NextWave's latest response, T-Mobile says that it is the "first-in-time" provider in the 2.5GHz spectrum band in New York City. As a result, the wireless provider claims that it doesn't need to turn down the strength of its signal until a "second-in-time" provider actually needs to use the spectrum. And as far as things stand right now, T-Mobile claims that NextWave doesn't actually need to use the spectrum. T-Mobile notes in the filing that the "second-in-time" provider (NextWave) has the obligation to notify the "first-in-time" provider ( T-Mobile ) that it has completed construction of its facilities and has started providing service to customers. Obviously, NextWave has yet to inform T-Mobile that it has completed construction and has started offering service to customers. This could put T-Mobile in the driver's seat, although it will be up to the FCC to reverse the two violation notices it previously presented to the carrier. - T-Mobile T-Mobile says that this obligation is "consistent" with previous FCC decisions and would seem to give T-Mobile a shot at prevailing in a situation where it might snatch victory from the jaws of defeat. This is one of those cases where a subject matter drier than your grandma's turkey sandwich actually does have some juicy meat to it. We will continue to keep an eye on this battle and update you when appropriate.
