When your device for some reasons does not work like expected, contact us right away. We generally can not give support or make a refund on things that happened days ago. You can send us a email to email@example.com, sms/chat/WhatsApp at +3546517368 or use the contact forms on this site. Please have your order number and modem name ready when you contact us. It’s also very important that you completed the modem activation/registration at hotspot.rent.
