eSIM Compatibility: Check Your Phone Before Buying

Check eSIM Compatibility Before Buying

Before buying a travel eSIM, confirm two things: your device supports eSIM and your phone is carrier unlocked. If either condition is missing, the eSIM may not install or connect.

What to check

• Your device model supports eSIM.
• Your phone is not locked to one carrier.
• Your operating system is updated.
• You have Wi-Fi available for installation.

iPhone notes

Many recent iPhone models support eSIM, but support can vary by country or region. Some regional models may not support eSIM. Check the exact model number before purchase.

Android notes

Many Google Pixel, Samsung Galaxy and other flagship Android devices support eSIM, but settings and model availability differ by region. Look for an eSIM or SIM Manager option in your phone settings.

After confirming compatibility, choose a plan: China eSIM, Japan eSIM, or browse all English guides from Code eSIM English.
