Because my mother has a care line system fitted in her flat, BT were unable to fit a new landline as it would interfere with it and no longer function properly. A relative suggested I use a 4G modem which has a port for a landline. This was good advice. The initial setup was easy and the phone connection was very good. I had one issue in that after updating the firmware, the phone stopped working. I contacting the IT support and the phone was soon back in use.

seems to be doing what it says on the box. I purchased a much cheaper competitor but it failed after a week , so i bit the bullet and paid more money and less hastle , as the sayin goes , you get what you pay for

A pity there is no 5hz connection

As a user of 4G for phone and broadband in a rural location I had been using Huawei/Soyealink b525-333 which has a RJ11 for phone over 3G, but since the 3G service discontinued recently, the 525 is only good for broadband. The TP-Link N300 Telephony Router has an RJ11 socket to connect a standard phone / dect base and the router works just great with Vodafone VoLTE (4G calling). Good price and as it’s TP-link works well with wireless extenders also in use.

There's no need for this 4G router when 5G exists, as 4G tends to provide a very slow, buffering Internet connection, especially for video streaming, and the wifi technology and range on this was abysmal. For a few quid more, you'd be better off getting your hands on a second hand 5G router with built-in phone ports.

GOOD points: This modem lets you plug in a phone, giving you the convenience of a landline phone and mobile internet.BAD points: The data rates are very slow on both 3G and 4G. For comparison, my 10 year old Samsung mobile from 2012 is much faster (1MB/s+, using tethering). This shouldn't be the case, but it is. Max download rate on this modem is around 250kb/s (IF you're lucky). Also, the UI is really slow, you will spend a long time setting this up.OPINION: Avoid this modem unless you need to plug in a landline phone.UPDATE (6/2023):This modem now stops working around every hour. The manufacturer support doesn't really work, and there are no firmware updates for this hardware version (V1). I'm in the process of starting a return (through Amazon), and I can't recommend this modem to anyone.

WiFi signal is good and strong but no 5g. I have tried this with different SIMs and all work, EE, Three, and GifGaf (O2). However, data speed is variable and definitely not as good as using the SIM in a iPhone, so if up to 10mb of data speed is good, then this device is ok.It will also connect to a standard phone line/lan.

I am using lebara sim to connect with 4G internet and it is working perfect. I can able to connect 4 systems and speed is still good. Initially TP link was not able to provide good speed and I connected with customer card team they gave proper guidance about the settings change needed. Same day after changing the setting it started to do its full functions. Worth to buy and good one.
