I've just gone self employed and need to change to either a pay monthly or contract deal because I need to call people on mobiles on different networks. Gone through about 30 quid of credit this month because I'm on standard pay as you go.. and that needs to change. I see that O2 are pretty useless on this, only offering O2 to O2 as inclusive calls from what I can see. Are there any decent deals at the moments that would suit my needs? I'd say I need less than 200 minutes a month.
