Good Idea, still useless documentation, but outstanding and dedicated tech support! *by M***. on Reviewed in the United States on May 10, 2019* The manual is as basic as possible it doesn't cover anything about USB tty's in the Cellular setup area. Unit works wit AT& T in the US but you have to literally search for the AP{N information. Just use "BroadBband". As proven by 6 hours of AT&T tech support and various troubleshooting they don't know how to set up anything but a cell PHONE.. Can't be used with 3g and 4g even though the write up matches the AT&T 3g and 4g specs. Unit appears well designed and well built. good craftsmanship and form / function of the physical unit. Software interface and manual cause it to be a bit difficult to get set up.Changed from two stars to 5 star for the dedication of the SerialLink support staff, and the aggressive response of tech support in trying to get this working. Support has been email questions and answers, today they logged in remotely and tested. It appeared to be a bad SIM card or bad APN. After replacing the SIM card I found the APN dat Only Devices on AT&T is "Broadband" Amazingly none of tech support knew this.Very impressed with support the working product and especially Serial Link support. Definitely a 5 star operation.. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect for RV Internet! *by M***M on Reviewed in the United States on July 14, 2020* I bought this modem/router for my RV and it works exactly as I had hoped! I placed an AT&T SIM card in it and changed the APN inside the system settings, which I configured via WiFi. Easy setup and works great! Much better speeds and settings than the system that came pre-installed on my RV, and much cheaper! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works ith Mint Wireless, low cost service *by R***S on Reviewed in the United States on March 14, 2020* This product is being used with a amateur radio project to remote a Dstar digital radio repeater. Performance is good and unit was easy to setup.. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/125415502-seriallink-slk-e900-industrial-4g-cellular-router-4g-lte-modem](https://www.desertcart.us/products/125415502-seriallink-slk-e900-industrial-4g-cellular-router-4g-lte-modem) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
