Is it necessary to have a SIM card to transfer pictures off an Iphone?

I have an iphone 4 with hundreds of pics on it and have had no luck. Some of the software I've researched online to assist seems shady and in any case all of it only goes as far as the iPhone 4s.

Can you still turn on the iPhone and have access to the pictures? I don't think pictures need a 3g or 4g signal. If you can, just get a cable that connects the iphone to your computer.

i've done that before, then just manually go to the folder your iPhone is under, some sort of external drive, and open the various folders to find the pictures you want. Then just manually cut and paste into a folder on your computer's hard drive.

try looking on youtube for what i mentioned with out adding any additional software. But, just manually going through the system folder of the iPhone when it's connected to your computer.

No. SIM cards have nothing to do with pictures (on any phone)
