eSIMs
eSIMs are generated and sent immediately after your order is completed.
Check your Email: Look for an email sent to the address you used during registration.
Wait 10 Minutes: While usually instant, please allow up to 10 minutes for the network to process the request.
Check Spam/Junk: Automated emails containing QR codes are sometimes flagged by filters. Please check your junk folder.
Still Missing? If you cannot find the email after 10 minutes, email support@onsim.uk. Our team can verify your details and resend the activation QR code.
