Customer support
How can we help?
Email support@tellsim.com for help with an order, installation, activation, usage, or payment issue. Existing customers can also open their dashboard to view current eSIM details.
Contact support
Email support@tellsim.com. Include the email used at checkout and your order number when available so the team can locate the correct purchase.
Installation or connection issue
Include your device model, operating-system version, destination, and what you see on screen. Keep your QR code, activation code, and full LPA string private unless support specifically requests them through an appropriate channel.
Before you buy
Confirm that the exact device model supports eSIM, is not carrier-locked, and can use mobile data roaming where required. Ask before purchasing if any compatibility or plan detail is unclear.
Refund question
Refunds are limited for digital eSIMs that can be delivered and used immediately. Review the refund policy before sending a request, especially if an eSIM has already been installed, activated, or used.
