Can I backup my iPhone 3G contacts to the sim card?

You cannot on the new iPhone without third party software that voids the warranty.

I am under the impression that that’s what the sim card is for. This way if you transfer it to a different phone, your contacts go with you.

Isn’t that one of the purposes of a sim card?

I have a backup of mine in my wallet in case my phone is either lost or stolen.

@Buttonstc – Exactly what I thought! Apparently, that’s not the case with the iPhone as @JONESGH indicated. It makes no sense at all.

Bummer! I was sick of having many many old and mostly irrelevant numbers on my sim card so I wrote down all of the important numbers and proceeded to delete all of my sim card contacts.

Then I bought an iphone and entered all of my contacts into my phone… couldn’t find the option to then save them to the sim chip but thought I would get around to finding out how eventually.

I guess this means I won’t have a back up of my numbers on my sim chip which is a shame.

Perhaps someone should design a free application to enable this.

I have an iPhone and that’s the one to which I was referring.

The guy at the ATT store actually made me a duplicate so I can’t imagine it’s just blank or something.

@Jones

What is the source of your info?

@Rachienz

Did you manually enter them all? When I got my iPhone, the ATT guy transferred them all automatically for me from my old Samsung.

Evidently, the iPhone sim is different from the ones which go into older models like my Samsung, but they just took care of the whole thing.

Did you get your iPhone from the Apple store? Are you not using ATT as your carrier?

They should have handled all of this for you at no extra charge if you are with ATT.

Right @Buttonstc. Thanks for your reply. They transferred my contacts to my phone, but they aren’t on the sim card. I guess I’ll go in to ATT and see what they say.

I remember when they did mine, there was the choice of to the phone of to the sim.

I chose the sim ( as I always did even with my old Samsung) because I couldn’t see any advantage of putting them on the phone. Eventually you’ll switch phones, right.

I settled this question for myself when I first got my Samsung. Prior to that when I had a Verizon phone there was no sim. What a pain!

No one has ever been able to give me any clear reason for why I should store numbers on the phone rather than the sim. Just doesn’t make any sense to me.

@Buttonstc – I am in New Zealand, we don’t haev ATT here. I previously had all my contacts on my Sim Chip which would have easily transferred over but I didn’t want to do that. I had many contacts that I was continually sick of seeing on my sim card so I just deleted them all.

I thought – no biggie – I will just enter the relevant ones manually and save those to the sim chip to have permanently… alas, I can’t now save these manually entered numbers into my chip.

I was not provided with a new chip for my phone, only my existing chip from my older phone which I have had with Vodafone for like 6 years.
