Bringing Your Cell Phone to Denmark

First all, I should note that all of this is based on my experience with T-Mobile and may not entirely apply to you.

Depending on your carrier, you will want to have at least a dual band phone (900/1900 MHz), preferably a quad band phone (850/900/1800/1900 MHz). My current-until-last-night phone was a dual band, and at least according to T-Mobile the frequency of the carriers I would be using in Denmark and most of Europe would be are on a frequency of 900/1800 so coverage might be a little spotty. Hence the purchase of a new phone (be quiet, it is only $30 after the annoying mail-in rebate).

In general, Europe has far superior coverage and I assume that Copenhagen will be no exception.

Also, you probably have to activate international roaming. For T-Mobile this is called WorldClass International Service. It is free, but may take a couple days to activate and you may have to try a couple of times to get it to work.

Also as you probably guessed phone calls on your phone will be pretty expensive, although you probably won't be making many calls. At least with T-Mobile, any call is a $1 a minute, including checking voicemail and including incoming calls even if you don't answer them - if your phone is on (hence, if you're not expecting a phone call I would keep the phone turned off). Text messages are cheaper at 35 cents. I'm not sure if this is cheaper than renting a phone there, but I figured this would be less work once I get over there and I wanted a new phone anyway.
