My brother who works in the UK asked me about this service (prepaid callthrough:

Do you think it's worth considering?
My brother has an O2 SIM (not sure which tariff however) with International Bolt-on. He wants to use it for calls to Poland (1p landlines, 7-8p mobiles, 5p setup fee). Of course, on top of it there's a fee to connect the access number 020 7112 7222 - I guess it's charged like "Standard calls" (i.e. UK landline).
IMHO it doesn't make sense to use this service to Polish landlines but to mobiles it would make some savings...
