Mobile phone service comparison websites

I have been asking around for the best mobile phone services,
is there a price comparison website stating what mobile services charge?

So far i heard fonic is a good deal,
Any advice on the matter?
thanks

Depends what your calling pattern is.
If you make a lot of international calls, www.ortel.de is supposed to be good.

I'd first find one which networks have the strongest signal in your area. You might find that narrows down your choices quite a bit. The "best" (ie cheapest) plan is useless if you can't actually use the darned thing, which may mean using a more expensive provider.

Maxxim now offers 8ct/min for all calls. SMSs are also charged at 8ct/SMS. It uses T-Mobile network, so coverage is good.
