If you're having trouble applying a promo code to your eSIM purchase, these are the most common reasons:

• Referral code restrictions: Reward codes starting with "R-" and referral codes can only be applied through our referral program page, not during checkout
• Expired codes: All promo codes have validity periods - check the expiration date in your original email
• Formatting errors:
  • Check uppercase/lowercase letters match exactly
  • Remove any spaces before/after the code
  • Avoid special characters not included in original code

If you've verified all these points and still can't apply your code, please contact[email protected]with the exact code and error message you're receiving.
