When do I install my eSIM on my iPhone?
We recommended you install your eSIM while you have a strong Wi-Fi or data connection to avoid installation errors.
If you’ve bought an eSIM data package to use on an international trip, it’s a good idea to install your eSIM while you’re still at home so you can make sure it’s installed correctly before you travel internationally.
But you can also install your eSIM when you’re already travelling internationally and you want to begin using eSIM data right away.
Will my data package activate as soon as I install my eSIM on my iPhone?
If you’ve bought an eSIM data package for another country and you’re installing your eSIM while you’re still at home, then your iPhone won’t be able to reach those international networks and your data package will not activate.
If you’ve bought an eSIM data package for the country you’re currently in, and you’re installing your eSIM while your iPhone runs the latest iOS software, your data package may activate immediately during installation. (Read more)
How to install eSIM on your iPhone
Once you’ve purchased a eSIM data package from aloSIM, you need to install your eSIM (digital SIM card) on your iPhone so it’s there when you need it.
It’s recommended to install your eSIM while you have a strong Wi-Fi or data connection, so you can do this while you’re still at home (prior to travelling).
Open aloSIM and choose your eSIM
Choose an eSIM installation method
As an iPhone user, you will probably see three eSIM installation methods: Automatic, QR code, and Manual. We recommend selecting “Automatic” if it’s available for your iPhone, since it’s the fastest and easiest method.
Tap the "Continue" prompts
Your iPhone will tell you that aloSIM would like to activate an eSIM on your iPhone, and you’ll tap “Continue.” Then you’ll see a nearly identical screen saying an eSIM from aloSIM is ready to be activated on your iPhone, and you’ll tap “Continue.” You may also see a third prompt saying you can continue using your iPhone while your eSIM is activating, and you’ll tap “Continue” again.
Tap “Continue” to approve the eSIM installation
Always select your Primary SIM as your iPhone's Default Line
Choose your iPhone’s Primary SIM if you’re asked to choose a Default Line to make phone calls or send messages because eSIMs don’t come with phone numbers. Even if you don’t plan on using your phone number while you’re travelling internationally, it still must remain your Default Line.
If asked, choose your Primary SIM as your Default Line
Always select your Primary SIM for iMessage & FaceTime
Even if you don’t plan on using your phone number while you’re travelling internationally, choose your Primary SIM for iMessage & FaceTime. (During the eSIM activation process, we’ll show you how to make sure iMessage and FaceTime are connected to your Apple ID so they work with or without your phone number.)
If asked, choose your Primary SIM for iMessage & FaceTime
If you're still at home, choose your Primary SIM as your iPhone's Cellular Data source
If you’re prompted to choose a default line for Cellular Data, that means your iPhone has more than one possible data source. If you’re still at home, choose your Primary SIM for now. If you’re already travelling and ready to use your eSIM for data immediately, choose your new eSIM.
If you’re still at home, choose your Primary SIM
If you’re already travelling, choose your eSIM
Now you'll be returned to the aloSIM app
If your eSIM installation has worked correctly, you should be returned to the aloSIM app and see a message that says “Your eSIM has now been successfully installed.”
Your eSIM is now officially part of your iPhone, just like a physical SIM card. (Except this one can’t be lost or damaged, and you can keep it in there forever eSIMs never expire.)
Your data package will only automatically activate under certain conditions
Your eSIM data package will only auto-activate and show as “ACTIVE” if you’re already located in the correct country and your iPhone is running the latest iOS software.
If you’re not yet in the correct country (or not running the latest iOS), the installation process has been completed, and you will be able to activate your eSIM data package when you’re ready.
