TELEPHONE PORT - This will enable the connection of a normal analogue telephone to make and receive GSM calls - this means that if you insert a SIM card that provides both Voice and Data you can make and receive calls using a normal telephone with call charges as per your call plan.
EXTERNAL ANTENNA CONNECTORS - The B315 4G Router has a removeable cover on the rear of the unit that provides access to 2 x SMA antenna connectors to enable the connection of an external antenna. You can then select to use the internal or external antenna as shown in the video below.
Here is a quick video that shows how to configure the B315 to use the external antenna
3G AND 4G COMPATIBLE - The Huawei B315 4G Router will work with any 4G Data SIM Card and will also work with any 3G Data SIM Card and if you use a 4G SIM card and dont have 4G coverage then the B315 will automatically use 3G instead.
PORT FORWARDING ON THE HUAWEI B315 4G ROUTER
The video below shows where the settings are to configure port forwardin on the B315 4G Router. This assumes that you have already decided on a method to remotely access your router for exapmple using a Fixed IP SIM card.
port forwarding will not work unless you are using a compatible mobile network service that enables you to remotely access your router - many standard mobile data SIM card providers use CGNAT so your 4G router only receives a private IP address so cannot be accessed and also means that services like DDNS / DYNDNS will not work and also port forwarding will not work so please check with your mobile provider whether your connection receives a PUBLIC or Fixed and accessible IP address to enable remote access to the router otherwise port forwarding will not work.
