Simple, donet want to pay a small fee? If there is such a requirement, Either don’t use it or pay £1,000 for you own charger, Oh, by the way, did they tell you, that you have to pay for the electricity it uses? How dare they!
Why the attidude Roger?
The problem with Ohme chargers is they are E-Sim only, unlike other chargers on the market that support both E-Sim and Wifi, many including lifetime E-Sim.
It may only be £2 a month now, but what will be next year or in 5yrs time?
