In general, I am satisfied with the device. I connected an external antenna, the reception is almost the same. I recommend, especially for summer cottages. Some pros: Accepts any SIM card. I have Tele2. Virtually nothing needs to be configured. Turned it on and everything went. Picks up a signal confidently. With its cons: Bad friends with a laptop (the Internet flies). But this is not the case with the router.
