When it comes to eSIMs, not all mobile phone models have the capability to use them. For example, Apple shares that you need at least an iPhone XS, iPhone XS Max, iPhone XR, or later iPhone model to use eSIMs. Additionally, iPhones manufactured in mainland China, Hong Kong, and Macau are limited to two nano-SIM cards for dual SIM functions. However, visitors who bought iPhones outside these countries can still use eSIM features.
For Android users, eSIM compatibility will vary across brands and models. To find out if your Android device is eSIM compatible, go to Settings > About > Show EID. If you can find an EID number, it means your device is eSIM-compatible.
Even if your mobile phone is eSIM-compatible, it’s also possible that your device is locked to your carrier, which means you aren’t allowed to activate eSIM until you finish your contract. To check if your carrier can preserve eSIMs on iPhone, go to Settings > General > About. Then, scroll down until you see Carrier Lock and check if it says “No SIM restrictions.” If you’re unsure or can’t seem to make your eSIM work, call your carrier to confirm.
On the other hand, most modern smartphones will be able to access Wi-Fi hotspots from portable internet sticks. So, if you’re traveling with an older model or locked phone, an external Wi-Fi stick may be your only option.
