Ive heard that you can use a nexus one in every country, but can I use it in all of those countries above without changing the plan and doing complicated things and paying and everything? Please help!!
If the Nexus One doesn't have a SIM lock (in most cases it doesn't), then yes. You can use them in the UK, Singapore, China and the US. However, it won't work on all carriers in the US because they don't use SIM cards.
