Is The iPhone 4 SIM Card To Blame For Reception Issues?

So we all know the iPhone 4 has some issues and among them, the worst one is probably the reception problem when you hold the device. As the internet did various testing on this problem, the issue was isolated to the lower left corner of the iPhone 4 when users cover the antenna. But was that really the problem?

Today, a MacRumors forum member posted a story of how his iPhone 4 signal issues had been resolved! While he was at an Apple Store for tech support on his iPhone 4, the Apple representative temporarily removed the SIM card and then put the SIM card back. The result was a drastic improvement in reception:

I went on my merry way, but realized something now. No matter what position I held my iPhone 4 in, the signal never decreased. I held it the many ways I know the signal issue pops and nothing. No bar loss, no signal loss, no call drop. NOTHING. So there you have it.

I am theorizing that moving the SIM card had something to do with the signal issue, because the only thing I have done to my iPhone 4 differently is take out and reinsert the SIM card. Other than that no other changes to it. No setting change, no software change no nothing. Just reinsertion of the SIM card.

Of course, the internet investigated and found that the SIM card may be making contact with the SIM tray and essentially causing a short in the reception.

To test the theory further, some users isolated the SIM from the tray or cut the other side to ensure the SIM was not touching the tray. Results have been mixed at best.

At this time, it is too early too tell what the real issue is, but I feel strongly that the reception issue is not just the iPhone 4 alone but that AT&T also plays a factor. We all know that the Canadian networks are more robust than our American counterparts, so let’s hope that when the iPhone 4 arrives here, we won’t have to modify our SIM cards or hold the iPhone 4 differently.

    The problems are happening in the uk too tho where they have better cell service than the US. Im worried that apple isn't going to do anything until the redesign next year and in a few years we're all gonna look like suckers for buying the “iPhone that cuts out when u hold it a cretain way”….

    Althoughh i also wouldnt be surprised if.apple had an “updated” version waiting to go, but wanted to unload all there current stock first so they don't lose money on them…

    What I want to know is not how many iphones are having this issue, but rather how many people's user experiences are being flawed because of it. It sounds to me thus far like people are just bitching about it for the sake of bitching about it. Is it actually interfering with their everyday iPhone use? Like, were you talking to Auntie Wendy when suddenly you touched the bottom of the phone and POOF!? She was gone? I mean seriously, this is only a REAL issue if it's stopping the iPhone from being an iPhone. I can't help but wonder how many people would have even noticed had it not been pointed out by the internet?

  • Man these reception issues are getting out of hand. I would like to test it firsthand to make my own conclusion with the networks here in Canada.

    It is definitely a design flaw, not the sim or AT&T….read the iPhone 4 review, page 2 – Antenna: http://www.anandtech.com/show/3794/the-iphone-4-review/2

    Right, I got myself an unlocked iphone4 from UK and am using it on my fido network in Canada. Of course I had to cut my sim card.

    I can ASSURE you all that I faced NO call drop or ANY other reception issues no matter how hard and where I held the phone. This I tested in Toronto and in the outskirts where 3G reception is not as great as that in Toronto.

    ZERO reception issues whatsoever …PERIOD
