The Vigor 2620Ln is a low cost router/firewall with LTE/4G as the headline connection method. In addition, it can use any one of three methods for its primary WAN (Internet) connectivity, falling back to one of the others in case of service interruption. It has a Dual-SIM cellular (3G/4G/LTE) modem, VDSL2 / ADSL2+ modem (Phone Line Broadband) and Ethernet (RJ45 - which can connect to many other WAN delivery sources), the Vigor 2620Ln provides extreme flexibility to ensure a reliable connection With the built-in 4G, the Vigor 2620Ln is ideal for mobile Internet connectivity, or locations which wish to use LTE as their primary connectivity method or temporary workplaces.  You have the benefits of a DrayTek firewall, with optional web content filtering, shared by multiple users on wireless or wired connections to the unit.  You slot regular (standard size) SIMs into the back of the vigor 2620Ln for use on any of the UK cellular networks or MVNOs (exc. Relish). The Vigor 2620Ln then provides Internet access to your local clients and the VPN facility fires up automatically and can provide a secure VPN link back to your HQ, or channel all of your traffic through a compatible 3rd party VPN provider for added security. Integrated LTE 4G/3G Modem The Vigor 2620Ln provides high speed mobile broadband connectivity for Internet access and VPN, with its built-in LTE 4G/3G modem. Downloading at speeds of up to 150Mbps and Uploading at up to 50Mbps. It's not locked to any mobile network and is compatible with all major UK mobile networks, such as EE, Vodafone, O2 and Three, as well as any MVNOs on those networks. The Vigor 2620Ln can even be used as an LTE modem so that you can connect another firewall or router to the Vigor 2620Ln. With its LTE Bridge mode, the Vigor 2620Ln directly links whatever's connected to the mobile broadband, without any additional network translation (NAT). The two aerials on the Vigor 2620Ln for the LTE/cellular connectivity provide increased gain and signal diversity for improved reception and a robust connection. The aerials can also be removed and replaced with specialist aerials (higher gain, outdoor) or an optional extension base used to position them most optimally. Ideal for Mission Critical Backup The Vigor2620Ln with a cellular service is ideal for mission critical connectivity such as retail/EPOS or security monitoring applications where continuous uninterrupted connectivity is essential. The flexibility of its interfaces means that your primary Internet connection can go through the Vigor 2620Ln, switching over to LTE when required, or the Vigor2620Ln could provide the LTE connection to an existing multi-WAN router/firewall. For additional failover, the Vigor 2620Ln also has a built-in DSL interface, compatible with an ADSL or VDSL line, as well as the option for Ethernet WAN (switchable with LAN port P2).  In all failover scenarios, the router continues to monitor the primary WAN feed and will switch back to that when restored. Alternatively DSL, or Ethernet can be primary with LTE/4G as failover. Constant Connectivity - Dual-SIM LTE Where connectivity is mission critical, a single cellular network can be a single point of failure, in the event of a mobile network outage. The Vigor 2620Ln has two SIM slots, so that in the event of one mobile network not providing Internet connectivity, the Vigor 2620Ln will switch to a secondary SIM and cellular network connection. It intelligently monitors for Internet connectivity and latency; If the primary 4G SIM's network can't access a required location, or is too slow, it switches over to the backup SIM to resume connectivity. For resilience in the event of mobile network outages, each SIM should be on a different cellular network (e.g. Vodafone and EE) and not 'virtual' networks which piggyback on the first (e.g. not Virgin Mobile and EE, as the former uses the latter's network). SMS Text Message Control & Reporting As a cellular network device, the Vigor 2620Ln takes advantage of text messaging (SMS) to allow remote interrogation and control. Send simple text message commands to the router from your phone to have it reply with its status (IP addresses, data usage), or reboot the router. Access to the SMS control features is secured with a PIN code and an Access List, a whitelist that allows messages only from your specified phone numbers to manage the router via text messaging. View SMS text messages received through the router's web interface in the SMS Inbox, for instance, checking for service messages indicating that you are low on credit. Or have the router forward received SMS messages to you via email, to ensure that you're continually updated on the Vigor 2620Ln's status. Send and receive text messages through the router from your web browser, or via command line, for automation and integration. VDSL2 & ADSL2+ Modem Many broadband connecti
