SIm card question for all iPhone users

[Bigair]

I activated my iPhone with the sim card that it came with inside of it. Should i put my old sim card in the iPhone? will this make for better service or change anything? rarely it gets stuck on no service and i have to put it in airplane mode and back for it to search for a service. Could this be because im not using the right SIM card?


thank you

I have cingular also before i bought the iPhone

No, keep the iPhone SIM card inside.

Your old sim card was deactivated when you activated the sim card in the iPhone.

Interesting. I can get access to the sim card? Is there a special panel/button?
