Thank you for viewing. This is a listing for a used PA-HT100LN network device. Purchased in 2018. Power-on was confirmed before listing. This is a SIM-free compatible LTE (mobile network) router. It allows you to build a WiFi environment with a low-cost SIM. You can easily and simply have wireless internet at home without the need for line installation. Official website details: https://www.aterm.jp/product/atermstation/product/mobile/ht100ln/ You need to enter the APN when using it (I think it can be used with any SIM except Rakuten). Please understand that we cannot accept claims or returns after delivery, so please purchase with this in mind.
