I've now got a MagicSim adapter for my smartphone, turning it into a dual-sim phone. So I'm ready to retire my old punting "dumbphone". It was a pain to text with anyhow (numeric keypad, I ended up compiling texts on my smartphone and sending them to the punterphone to be forwarded on to the WG), and I carry the smartphone to punts anyhow, it's useful as a satnav and for googling unfamiliar hotels etc.
So I might as well take this opportunity to upgrade my security, as my old punterphone was registered in my name. I'll need a new sim. Here are my requirements:
Standard size sim, not a micro sim.
Anonymous: can be purchased with cash over the counter somewhere (not mail-order), left unregistered or registered under a false name, and topped up with cash. No credit/debit card transactions involved.
Not on Three, which is the network my main sim is on: I'd like to be able to switch networks. O2 isn't great in my area, so I guess EE would be best.
Data allowance or cheap data: it's going into a smartphone, after all.
Recommendations?
