Hi folks

I'll be in NZ for about a month.

Normally, just roam with my UK O2 SIM, but this time I was planning on getting a 2degrees SIM on arrival, and buying a 'Combo pack' with 50mb data for starters.

My iPhone is unlocked.

Is it simply a case of sticking the new SIM in? Are there a lot of settings to fiddle with? I'll need to swap back to the O2 SIM every once in a while to check for messages.

More importantly, can I turn off 3G usage easily? (I expect to have pretty frequent access to free wifi, and I don't want to be using up my 50mb of data unnecessarily.) Ordinarily, I'd just turn off data roaming, but I guess with a local SIM I wouldn't be roaming any more ...

Thanks
