SWMB Ltd described a solution to my woes and gave excellent answers to all my questions so I finally took the plunge. I am so glad I did. The company was very responsive throughout the process. Answering all my questions and showing an in-depth knowledge of the technology and practicalities. On the day, the installer showed commendable perseverance in finding the best 4G signal. The installation itself was quick, clean, and efficient. The small external antenna is visually unobtrusive. I am up and running with 20-30 Mb/s DL/UL with my VoIP phone working. Time now to cut the cable to Openreach! Thank you to the SWMB team.
