Reliable WiFi for remote areas
I installed this solar-powered LTE router at a remote cabin where there’s no wired internet, and it works better than I expected. Setup was simple just insert a SIM card, position it where it gets sunlight, and you’re good to go. The connection is strong and consistent, even in spots where my phone struggles to get a signal. The WiFi range easily covers the area around the cabin, and the built in battery keeps it running smoothly day and night. The device feels tough and weatherproof. It’s handled rain, sun, and wind without any issues. If you need internet in a rural or off-grid location, this is a great solution. And the best part it runs completely on solar power, so there’s no extra cost to keep it going.

Big solar panel! Keeps battery charged!
This got my internet to the barn! Didn't think it was possible. Fairly easy setup, the solar panel is adequate to keep the batteries charged. Been up and running almost a week and haven't noticed any interruptions. Nice to extend my wifi cameras out where I need them.

Works as it should
Easy to set up. Took around 30 minutes except for the time to find my drill. Using it to cover the dead spot in our home because I didn’t want to pay for another “pod” from Xfinity.

Ich verwende 2 Kameras auf meiner Pferdewiese im Freien. Mir fehlte WLAN. Ich habe eine Prepaid SIM im Einsatz, da die mitgelieferte mir nicht zusagte. Bei dem SIM Kartenwechsel musste ich den Router ausschalten und wieder neu einschalten. Dann funktionierte alles wunderbar!

Solidly constructed unit. However it functioned badly. It needed increasingly frequent power cycling to maintain a connection. The power switch is not well placed to make this easy. After a couple of months it stopped working completely. In the end I bought an external 4G antenna and a TP-LINK ARCHER modem which never needs power cycling and acheives 4G download/upload many/many times greater than this unit.

Prodotto pessimo Il funzionamento del 4g è a singhiozzo. È necessario spegnere e riaccendere spero il router per far funzionare la connessione 4g. Il tempo massimo di funzionamento continuo è stato per non più di 3 giorni e non dipende dalla configurazione e. Idea geniale se solo funzionasse Mi dispiace non poterlo più restituire
