Before you buy a travel eSIM, it is worth checking that your iPhone supports eSIM and is ready for digital activation. This guide explains what to look for, how to do a quick compatibility check, and where to find Apple’s official instructions.
Most eSIM issues are caused by device compatibility, regional model differences, or a locked handset.
Most iPhones from iPhone XS, XS Max, and XR onward support eSIM, but there are regional exceptions and model differences to be aware of.
If your phone is network locked, it may refuse to install a travel eSIM even if the handset itself supports eSIM.
Keeping iOS up to date improves eSIM compatibility and ensures newer setup methods, such as QR code long-press and carrier links, work properly.
A quick way to test for eSIM support is to check whether your iPhone shows an EID number.
Open the Phone app on your iPhone and dial *#06#.
If your iPhone displays an EID number, it usually supports eSIM.
If you only see IMEI numbers and no EID, your device may not support eSIM.

Apple states that eSIM setup on iPhone generally requires an iPhone XS, iPhone XS Max, iPhone XR, or later, together with a carrier or worldwide service provider that supports eSIM.
In general, the following iPhones support eSIM:
Not every iPhone model sold in every market supports eSIM in the same way. Certain China mainland, Hong Kong, and Macao variants can differ from the standard international pattern.
Even on a compatible iPhone, a carrier lock can prevent a travel eSIM from being installed or used. If you are unsure, contact your primary network before travelling.
Apple supports several ways to activate an eSIM on iPhone, and Simpal uses the methods most convenient for travel customers.
After purchase, Simpal can provide a QR code that you scan from your iPhone to add the eSIM.
On compatible iPhones, you can often install directly from the order confirmation page or from the email sent after purchase.
If needed, you can also enter the eSIM details manually in iPhone settings using the activation information provided.
Your order confirmation page updates automatically while your eSIM finishes provisioning. This is often instant, but it can occasionally take up to about one minute.
iPhone can store multiple eSIMs, so you can keep previous travel plans saved and switch between them when needed.
It is best to install your eSIM while connected to Wi-Fi or another stable internet connection.
