Not your usual telco
I am usually skeptical of most phone companies as they frequently over promise, under deliver, and charge a lot. Orange does none of these. There customer service rather call centre, SMS, or email is great. They are quite helpful, and even suggest plans to you that fit your needs and not their profit lines needs. Although I do have an occasional issue with signal strength in some parts of London, I am a loyal Orange customer because they tick every other box of what I look for in a company.
