Is your iPhone an eSIM?
Basically, an eSIM is a digital SIM that allows you to change cellular carriers at anytime. You can store up to eight eSIMs on your phone at one time, and you don’t have to worry about losing or breaking the physical SIM card.
Apple is introducing support for eSIMs on its latest iPhone models. But if your carrier doesn’t support it, you could find it challenging to use the feature.
Adding a second line
The iPhone XS, XS Max, and XR first introduced a dual-SIM feature that lets you have two phone lines on one device. You can associate a physical nano-SIM card with one line and an embedded SIM, or eSIM, with the other.
There are also apps that can offer a virtual second line on an iPhone, such as iPlum. These provide a toll-free number with voice mail and texting capabilities.
In addition to the eSIM and other options, iPhones have a nifty little trick for switching off a line at a glance. All you have to do is swipe down from the top-right corner of the screen to access Control Center.
You can also find apps that let you do a lot more than just add a second line. These are usually referred to as VoIP services, which stand for "voice over internet protocol." They typically have a data plan and can send and receive SMS messages, though you'll still need an active cellular plan to make and receive calls.
Adding a second cellular plan
When a carrier or mobile network supports eSIM, you can set up a second line on your iPhone. This is useful if you want to keep your personal calls separate from work-related ones.
Adding a second cellular plan to your iPhone is a fairly easy process that will take a few minutes to complete. First, make sure your carrier or mobile network supports eSIM and then follow the instructions below to add it to your phone.
Using a second cellular plan on your iPhone will allow you to avoid international roaming charges and save money on data while traveling abroad. You’ll also be able to choose which line to use for iMessage and FaceTime as well as to enable Allow Cellular Data Switching, which allows you to use both cellular plans at the same time.
Adding a data plan
A data plan is a type of wireless service that allows you to access the internet through a mobile carrier. It can come in different types and data tiers, and a user must select the one that best suits their usage needs and budget.
It can also help prevent you from going over your data limit. Many people end up exceeding their data limits without realizing it, and this can result in expensive bills.
Adding an eSIM on your iPhone is simple, and should only take a few minutes. It’s usually a good idea to check with your carrier for instructions on how to do this.
In some countries, your carrier will send you a QR code that you can scan with the camera on your phone. You can also enter the eSIM information manually. If you do this, your new eSIM line will automatically be activated.
Adding a Wi-Fi hotspot
When you need a Wi-Fi connection, but there’s no available network nearby, your iPhone can act as a portable hotspot. It can do this by acting as a wireless router and using your phone’s data plan to connect devices like your laptop or tablet.
This process is called tethering, and it can save you from paying the carrier fees for a mobile hotspot or consuming your data plan faster than normal. It also lets you share your phone’s cellular data with a device that doesn’t have WiFi or USB connectivity.
You can create a personal hotspot by going to Settings > Cellular and tapping Personal Hotspot. Next, toggle on Allow Others to Join and enter a password, if necessary. You can then connect to your iPhone’s hotspot with any other device that has Bluetooth or Wi-Fi, or you can connect through a USB cable.
