eSIM is as secure as SIM cards as it utilizes the same encryption and authentication protocols. Actually in some aspects eSIM is more secure than SIM cards because it cannot be physically swapped.

Cellular data eSIM doesn’t offer mobile numbers for calling or SMS. But you can use all your mobile apps that provide calling and texting including FaceTime, WhatsApp, iMessage, Zoom, Skype, etc. 

Of course. Most eSIM devices support having two lines active at the same time. So you can keep your primary line “on” for calls/text, while you can use eSIM for cellular data. Just make sure your data roaming on the primary line is not activated to avoid roaming charges. 

For eSIM-enabled iPhones (e.g. XR or newer models), you may manually activate Celitech eSIM by going to:

Settings > Cellular > Under Cellular Plans tap “Add Cellular Plan” > tap “Enter Details Manually” then under:

  • SM-DP+ Address: fill this field with
  • Activation Code: fill this field with the provided activation code (format XXXXX-XXXXX-XXXXX-XXXXX)


Go to Settings > Cellular > under Cellular Plans click on the eSIM plan > Toggle “Turn On this Line”.

For iPhones (iOS 14 or later), this is how you can check:

    • Open “Settings” and scroll down and tap on “General” then select “About”
    • Scroll down to “Carrier Lock” if you see “No SIM Restrictions” then your iPhone is unlocked
