IPhone can't make calls... "network lost".

Hi, I bought an iPhone in NYC and I unlocked it back in Mexico; it worked alright for about three days, but suddenly one day it did not let me make or receive any calls at all. I did not update the software, nothing in the settings was changed, I only synced it to iTunes and no more. It displays the following message: Your network was lost, please choose another network in settings. But it still does not work. I can use everything, TouTube, Weather, Email, iPod, Safari, everything works fine, it's just that I can't make or receive any calls at all :( Can anybody tell me what can I do, since I'm in Mexico. Is there any way I can fix it on my own?

    Hi, I have a similar issue with mine. It was also unlocked and updated. It worked ok although while talkinging it tends to cut out.
    I updated one of the icon cynia or something like that, as i thought it might help with stopping the cutting off of conversation. I updated that in the morning and by the time i went to bed i could not access the phone. Other parts are ok..sms, weather, etc.

    I got an unlocked iPhone in China, and it worked for the first hour or so with China Mobile and now get a "Network Lost" Error.  Only thing I can think of is that I used the phone to try to access the app store, could Apple have done something through the app store access to shut off my service?

Ladies and gentlemen!
Before you restore or update your cracked iPhones or doing anything silly to get you further in a soup allow me to suggest a simple technique that worked for me.
My problem was quite similar to the one you guys have posted above. I could do everything else with the iphone, even receive calls but when it came to making calls, the phone wouldn't let me do the same. It would return a Call Failed message!
If you have the same issue try the following:

Go into the phone settings and turn call forwarding, call waiting, show my caller id, and TTY off and reboot.

If that doesn't work try turning call waiting, show my caller id, and TTY on and reboot and it should work.

I'm not sure why this would work but it did for me and I hope it also does for you. Good Luck

If you are UNABLE TO make any calls,call screen freezes,does not allows you to use keypad..DO THIS TECHNIQUE.

1- Installer > Utilities >Find application name KATE >Hit kate and on top right UNINSTALL it.
After its uninstalled

2- settings>General > about > Reset>Reset all settings.

3- Shut it off and restart after 2 mins.

Hope it works for you guys.

This is what I did the first time I got the ‘Repair Needed’ error on my iPhone:
1) Take out the Sim
2) Turn off your iPhone
3) Turn it back on
4) You will get a message, something like “No Sim”
6) Insert your Sim Card
5) It will take a moment to activate, then your all set.

You are not going to want to hear this - but you did update the software.

Apple placed an update in the Itunes software that crippled the cell capability for the IPhone if the declared network was not one of the two approved networks for the phone.

At this time there is a solution to this - there is a program called jailbreak for the IPhone. According to the documentation the solution to your problem is to use this program and "jail" the IPhone, reapply the Itunes update that broke it, and then "jailbreak" the phone to restore connectivity.

One of the intended effects of the Itunes update was to delete the network settings on your card, which means you will need to goto your provider and have the phone reset to their network or restore the settings yourself providing that you made a backup.

It is my understanding that the EDGE and WiFi data connectivity functions are not broken by this problem.

To obtain a copy of the program you need, Google it and download it from a local server. Be aware that as always, when you download and install software from Internet there is a potential risk - be sure to have an updated virus scanning and killing app on your system and scan the file prior to installing it.

I hope that this helps you.

  • Anonymous Nov 15, 2007

    As I understand it once you reset the phone you need to reapply the last ITunes update so that the update version number is the most recent, that way when you jailbreak the phone ITunes thinks that it has had the most recent version update applied and so does not try to kill the settings again.

    Hi
    of course i did not get my iphone from apple or service provider:-) so, this could be a real issue to get the phone to work correctly.

    I cannot understand why it keeps cutting out.

    A friend told me it could be the hardware(iphone itself) not a software problem as its been fully updated.
    Any solutions?

I have a HTC Desire that I bought before 8 months on Three Network from United Kingdom.Now I have moved to a different country but my cellphone seems to be network locked.How can I unlock it now?

I bought my HTC Desire from Three Network about half a year ago. Just a couple of days ago, I called Three at 333 to get my unlock code. It took about half an hour to verify me and my credit card details. I suppose you could call their international number at 00447782333333. It costs me 15.32 pounds to unlock.

IPhone "Network Lost" message every 3 minutes!

Go - Settings/General/(scroll down to) Reset/Reset Network Settings.

Phone will turn itself off and on again. Et voila - no more annoying message saying "Network Lost"

Note: This procedure doesn't mess around with any of your other settings, applications etc.

Good luck.
