Yes, i changed from Genie sim to £25 a month contact and i was allowed to keep my number
Just call them up and ask for a number port. It's that simple :)

No, the iPhone 3 does not support dual SIM functionality. It is designed to accommodate only one SIM card at a time. If you need to use two SIM cards, you would have to switch them out manually, as the hardware does not allow for simultaneous use of two SIMs.
Of course. SD cards or MicroSD cards are just memory cards. Unless you are meaning sim cards, then that's a different story.
If your phone is unlocked - yes. It's simply a matter of swapping the existing SIM card for a new one.
You can get the provider of the phone to switch them over if necessary. Those with SIM cards, if both phones use them, can be switched over yourself.
Cellcom in Wisconsin does not have sim cards, wish they did. I have heard that you can get a sim card from them but non of their phones have a spot for sim cards.
No, it only needs one SIM card. The Blackberry Storm2 9550 is both CDMA and GSM, and CDMA phones do not use SIM cards. So you would only need to use one SIM card when you switch the phone's mode to GSM.
Nope, cause metropcs does not use sim cards but a esn number. Sim cards are usually associated only with GSM phones, and metropcs Verizon and sprint all use CDMA
Verizion uses CDMA and CDMA networks don't use Sim Cards cause i only know of GSM providers using Sim Cards Sim Cards like tell the phone your number , minutes and stuff. a phone can't work on a provider without a Sim Card (CDMA phones are programmed via there OS or circuit board).
The Phone Number is assigned to the SIM card. If you put the SIM card into the new phone, the number will be the same, However not all SIM cards wil transfer to all phones.
