    Default iPhone keeps losing signal

    Yesterday, randomly, my iPhone 3GS with Telstra keeps losing the signal. Drops out, then says searching, then says No Signal. Then a couple of minutes later 3G comes back. My wife has the same setup but it's not happening to hers. Not sure if it's the phone or the sim card. Popped the sim card out and reinserted it but it didn't fix it. Any ideas anyone?

    I had this problem too - I think it's a SIM contact issue. I stuck some plain labels (cut to size on my SIM to the non-metal contacts side) to make the fit more snug and so far no more signal dropouts. Has happened to me on other phones (eg Treo 680) too.

    My 3GS started doing just that so I took it to the Genius bar who suggested that since it wasn't throwing any error codes that it is most likely a carrier issue and I should get a new SIM (or ditch the carrier ). Of course I'm with Optus, that bad. They have just opened a store about 3 doors down from the Apple Store, that's good .

    The girl in the shop asked me how old the SIM is (at least 3 years) and tells me you should replace your SIM every two years. Talking to other Telco peeps I know it seems this was more of an issue as SIM technology was changing about 5 years ago when chip capacity was increasing and voltages were changing, not so much of an issue anymore, but I digress... SIM replaced, fired up and away I go.

    Flash forward to the next day and the phone stays on "No Service" all day, that's Bad. But I managed to get a genius appointment for 1:30pm that day, that's good . Simple replacement and away I go as good as new (and without the stuck red pixel I had, which the dude tells me would have been replaced without question *slaps head*).

    A week later and the Wife's 3G is doing the same thing (mind you this was a replaced by a genius for dead WiFi about 6 weeks earlier). Again into the genius store and a new handset fixes the problem. Don't get me wrong, problems are fixed quickly and easily and the service is great, I'm just sick of having to go there. Luckily I work close enough that it's not too much of a hassle, still love the phone

    Long story short, go to genius, get new handset.

    Thans for the feedback. It would seem to be the iPhone not the SIM card as I put my SIM into my wife's iPhone and it works perfectly but now her SIM fails in my iPhone. Being Waaaaay over in the West we don't have an Apple store. I bought mine from the Apple store on line about 3 months ago. Is it a major hassle getting it exchanged over the net? Should I start with a phone call to Apple Australia?

    Yes, I would call them. They'll discuss the phone with you and if it's a warranty issue they can immediately mail you a new one, and then you mail the old one back to them. Its called the advanced replacement scheme I think and is covered free if you have Applecare. Alternatively its $29 or so if you don't have it.

    Alternatively, though, if you would rather they assess it first, then there is no charge payable but you mail them your phone and they send it back (or a replacement) when they've made an assessment. No iPhone for a bit though!

    Their phone number is bottom of the page here.

    Default Anyone had the paid swap over experience?

    OK I've done a full restore and contacted Apple support and after putting my wife's sim in to verify that it also fails hence it's the iPhone which is now not only losing 3G but occasionally my wifi and even shutting down and refusing to open for a few presses.

    Being in the West the first option they gave me would probably end in a 3 week turn around. Tried ringing 4 local Telstra Shops but just got their voice mail. the Third option is a $39 fee plus a $900 bond to send me an iPhone and then I will return the stuffed one.

    I like the third option but wonder if that works smoothly. ie they return your $900 without any fuss. I'm certain the iPhone is stuffed. But suppose they say there is nothing wrong with it or that some how I've damaged it (which I haven't. It's my pride and joy and I look after it like a baby) will I end up with a $900 charge?

    It's all a bit scary. Why the hell can't we have an authorised store in WA? Nextbyte in Nedlands are their authorised dealer but not to do that it turns out as I rang them.

    My iPhone is also dropping service... Other phones are not are not seeing the signal drop outs.

    No Signal displayed in top LH corner of display. Sometimes just going into settings and toggling airplane mode ON/OFF will restore connection to the network. Other times a reboot of the phone is required.

    I'm on Optus and running software version 3.1.2 build 7D11.

    I also have noticed this over the past few weeks...
    never happened on my iPhone 3G. When I won (thanks again iWorld Australia) my new iPhone 3G S, it didn't happen for the first few months - just lately.

    Not convinced it is the SIM card... as it finds it quickly again.
    Suspect it is something to do with maybe when there is less coverage? weaker signal? interference locally? Maybe software upgrade has even make the connection with Telstra easily disrupted?

    It does pop up with a lost error... but even by the time I noticed the error the signal strength has returned.

    Default Oh No. Replacement doing the same thing

    Basically got a replacement iPhone just now and it is still doing it. Whilst I didn't have it for 5 days awaiting the replacement unit I borrowed a Samsung 3G flip phone. I t worked flawlessly for the whole time didn't miss a connection ever. So it's not the SIM and the replacement appears to be a new one. What can I do? Just keeps losing the signal and then reconnecting. I'm tempted to try what someone did here and put a cut to size sticky label on it to bulk it out.
