I've occasionally suffered from the issue whereby the Desire drops the network signal and never recovers from it unless you either turn airplane mode on and off (which sometimes works) or power the phone down completely for a few minutes, which has always worked so far. However, I've had the problem 3 times already today coupled with the message "No SIM Card in Phone" ...... The only way around this is to power down the phone for at least 5 mins and restart. Anyone have any ideas re this ? Is it a phone, network or even a sim card issue? Can live with it if it happens once a week or so, but multiple times a day is a real pain!!
No help, but i've never had that issue, not once. I lose signal quite a few times too living in the sticks.
This happened to me today for the first time. But it automatically went to airplane mode and when I turned it off it came up with the no sim card detected notification. A reboot fixed it, however I did not have to wait 5 mins as you did. I am pretty sure it is not a sim card problem since it was from my old phone which never had similar problems. I currently have the HTC desire with Android 2.1. No idea what caused it though.
OK, not sure if this is the fix ... but it seems to have fixed mine. I turned the sim lock to off, so there is no pin needed to unlock. I think there was a problem where it could not unlock the sim.
Thanks for the input guys ...... troj0, I didn't have my sim card locked so hopefully your fix has solved your problem permanently. nx1977, I took your advice and contacted T-Mobile who sent me a new SIM card which seems to have cured the issue completely! The phone and original SIM card was only a month old and sourced from MobilePhonesDirect, so perhaps I just had a duff one.
I have the same problem. I tryed to change sims and it was same problem, too... So now i`m wondering if tis sim card or the phone...
Had the same with mine today. As it was out of warranty i took it apart to have a look. As it turns out it is an issue with the design of the simcard reader as far as I can tell. At the back if it there isnt anything stopping the sim card from hitting the battery and going in to far (or at least there wasnt on mine). After i realized this I put my sim card back in, ensuring that I didnt push it right the way back, It now works. As far as i can tell there is a little bit of resistance when its in far enough but pushing it to much pushes it past where the reader can read it. Hope this helps
One of many problems i have encountered with my HD, failed GPS antenna, sent back to HTC for repair, random changes in app settings, ringtones and of course signal dropping out accompanied by the re-starting no sim card message. Im currently with Vodaplank, my wife has the HD with Treemobile works fine, no issues, put our phones together activate GPS hers locates within 3 seconds mine takes up to 30 seconds. Take my sim card out and put it in her phone works first time every time. I think i have a LEMON but i also think the network adaptive software has something to do with it, maybe. What i do know is HTC wont be my first choice at upgrade time and after 10 years with Vodaplank unless they can offer me something truly irresistible neither will they.
