Yesterday I arrived in Bangkok, as I have done many of times before. In the past my Samsung Galaxy S5 has automatically, with the same PAYG SIM card as I'm using now, registered with a local network within a few minutes of being switched on. This time it didn't. Now, a day later, I've been unable to register with a local network either manually or automatically, even though I can see about 10 available. I topped up my card with £50 prior to departure, so that is not the issue. To compound my frustration my UK provider Orange or its parent company EE publish no contact info for help, other than phone or snail mail. Can anyone help please with accessing local networks or Orange/EE?
