Didn't Receive Your eSIM Email? Yahoo, Hotmail and Outlook May Be Blocking It
Waiting for your travel eSIM but can't find the email? Don't panic. In many cases your order has been successfully processed, but your email provider may have filtered or delayed the message.
This is most commonly seen with Yahoo Mail, Hotmail, Outlook.com, Live.com and MSN email accounts, although it can happen with any email provider.
Why Does This Happen?
Travel eSIM emails are a little different from normal emails.
They often contain:
- QR codes for installation
- Activation instructions
- Download or installation links
- Technical information such as ICCID numbers
Unfortunately, automated spam and phishing filters sometimes mistake these legitimate emails for suspicious messages.
This is known as a false positive, where a genuine email is incorrectly identified as spam or potentially unsafe.
It's Not Just AirSims
This is something that affects many businesses across the travel, technology and software industries.
Email providers are constantly updating their security systems to protect customers from scams, phishing attacks and malicious QR codes. While these systems are important, they occasionally block legitimate emails by mistake.
Which Email Providers Are Most Common?
We've occasionally seen customers experience issues with:
- Yahoo Mail
- Hotmail
- Outlook.com
- Live.com
- MSN.com
Most emails are delivered successfully, but these providers tend to use aggressive filtering that can sometimes quarantine genuine messages.
Where Should I Check?
If your eSIM email hasn't arrived within a few minutes, check:
- Spam or Junk folder
- Deleted Items
- Quarantine folder (if available)
- Focused / Other Inbox (Outlook)
- Promotions or Updates tabs (Gmail)
Also search your mailbox for:
- AirSims
- support@airsims.com.au
- eSIM
- Your order number
Why Do QR Codes Trigger Email Filters?
Cyber criminals sometimes hide malicious websites inside QR codes or shortened links.
Because of this, many email providers inspect emails containing QR codes much more carefully than ordinary emails.
Legitimate businesses, including travel eSIM providers, can occasionally be caught by these automated systems even when the email is completely safe.
Can Delivery Be Delayed?
Yes.
Some email providers temporarily hold messages for additional security scanning before delivering them. This may result in delays ranging from a few minutes to, in rare cases, several hours.
What Can I Do?
- Check your Spam or Junk folder.
- Search your mailbox for AirSims or your order number.
- Wait a few minutes and refresh your mailbox.
- If you still can't find the email, contact our support team. One of our agents will get back to you during business hours. 💡 For efficient service please have the order number ready and/or the email address used when ordering.
Planning Ahead
To reduce the chance of missing important travel emails, consider using a reliable email address that you regularly monitor when placing your order.
Many customers find that Gmail tends to deliver transactional emails more consistently, although no email provider can guarantee 100% delivery.
