Just upgraded to HTC 8S - Urgent help needed!!!!

[Anonymous]

So I have just upgraded my contract today and chose the HTC 8 S, I asked the person I spoke to about sim cards as I have a bog standard one and I was advised that I just put the sim card I have already into the phone... now I have been reading reviews online and apparently you need a micro sim card?!I'm really annoyed now because surprise surprise as per usual I get told in correct information, anyway, my question is where do I get their some card from?? And does this mean I have to change my number again?

Thank you

You can call O2 or get one from an O2 shop, you can keep your number.

Well it's a bit complicated as I have upgraded my younger sister's contract to get a new phone sooner than my contract that ends next year and I have ordered it under her number.. so will they allow me to use my number instead of hers for the sim card but keep my plan and use the sim card that my sister has for the upgrade plan which is less date, txt etc?

As long as you swap YOUR sim everything will be fine.
