Please be careful when talking about things in other countries.

In the UK, and many other places abroad, yes, there are cheaper options. In the US, TMobil is actually the cheaper of the two (read that... TWO) providers for GSM. Especially if you're bringing your own phone, as they're the ONLY provider in the US that offers a non-subsidized price plan. The non-GSM providers are just about as expensive, and all of them also roll in subsidies for their devices.
