But why would t-mobile offer 3 month early upgrade to me when my online account says I can change plan in March (1 month before end).

I suppose it could be t-mobile but I would rather I was notified by post or email rather than getting a cold call out of the blue (especially given t-mobile lost customer data last year).

because if you accept an upgrade your with them for another 12,18 or 24 months making them money if you downgrade your plan you make them less

Got a call from an almost identical number (one digit out) a couple of weeks ago, my earliest upgrade is the end of Feb. The caller said she was from t-mobile offering me an early upgrade, she asked my name, which I gave, then started spouting some nonsense about data protection and asking for my account password 'to check my usage and see what she could offer me'. This set off alarm bells, so I told her in no uncertain terms that I would not be giving out any personal info to an unsolicited caller. The upshot of it all was that I terminated the conversation despite her protestations that she was genuine.
Anyhow, the next day I rang T-mobile cust services and they confirmed that this was one of their marketing people and the call was genuine! I then asked about an upgrade and was told that my earliest was 24/02/10, which was when I expected it, so no upgrade for me!
No way was I giving out personal details to someone I didn't know from Adam, it seems as though t-mobile don't have a clue how to deal with the public these days after all the fuss over loss of personal data I would think they would know better than to try cold calling from an unrecognised number.
