New official T-Mobile UK Data policy
As far as T-Mobile Data allowance is concerned I found the following on their site...
''... If you join T-Mobile before 30 September 2011 and select a 24-month price plan of £25 a month or more, the good news is that there's no fair use policy. Remember that you can only use internet on your phone in the UK and you can't use your phone as a modem (tethering) or use internet on your phone for peer-to-peer file sharing or making internet phone calls...''
Comment: do they block voip packages????
''... If you're choosing any other pay monthly plan (<£25), please see the fair use policy below.
However much you use the internet, you'll never get charged extra
We're the only operator to offer you a fixed price for browsing and emailing on your phone with no limits and no extra charges. Use 3G for getting online on your phone when you're out and about. Never pay more than your monthly fixed price. You can always browse and email with no limits.
Is there an allowance?
You can browse and email as much as you want. There is a 500MB allowance for streaming videos and uploading and downloading files. If you hit this limit during the month, you won't be able to do this stuff again until the next month.
For the best internet on your phone, connect to your home WiFi, so you won't even touch your 500MB allowance.
What about using apps?
Some apps use a normal internet connection, so they will work just like your browsing and email allowance. But there are some apps that use streaming connections, so these will fall into the 500MB allowance...''
So their new fair usage policy discerns between ''normal'' data and ''streaming'' data''. (packet inspection??) Web browsing and email sync fall into normal data category that is unlimited and does not count towards your 500MB download data allowance
When downloading a file off the internet (let's say an app off the MarketPlace), or streaming a movie, you are consuming data from a 500 MB data ''pool''. If you exceed tgis limit, you cannot further download/stream, but you can still continue to have data access for http/browsing data. apps like netflix, vevo, youtube fall into that download data category, I assume
One question arises, what happens with voip data packages (if there are any voip apps for wp7 for the time being, anyway there is a google voice client I recon)
