Re: HTC HD7 switching between bands

It's handy to know what features use what frequency for example, I went to the US last month and left the data roaming and Wi Fi options enabled - I ran up a bill of almost £100 for four days, not just on data but texts too.
A couple of slightly o/t questions if I may;
1. If I switch off data and roaming will the phone still 'roam' to find a carrier in the US for voice calls only, also will emails still come through on 2G?
2. If I switch off data and roaming but leave Wi Fi on will it find my US office network or will it not even begin searching of it?
Is there a table or reference anywhere for what does what?
Ta,

Yes to both but I would only switch the wifi on when you want to use it. Constantly on will mean it's continually searching for wifi connections and will be a burden on your battery.
Also make sure you switch off voicemail before you leave the UK, the way it is routed means you will be charged silly rates if someone leaves you a message.

Re: HTC HD7 switching between bands

Cheers for that, so just to clarify emails will still come through with roaming and data switched off overseas?
If its coming through on the 2G voice is it still classed as data, sorry to be pedantic on this but I never seem to get a clear answer when researching myself.
btw, switching off the 3G option has made a huge difference, the phone works normally with no missed calls, in addition the battery life has doubled to around two days.
Could this be something to recommend to O2 customer support?

If data roaming is off unless in wifi coverage abroad no emails will come through as cell data is blocked 2g/3G

Re: HTC HD7 switching between bands

Thanks again Adam,
As I mentioned in my post about researching the subject it may not be clear to users, indeed two replies from knowledgeable posters with different answers to the same question.
