I do not see why the trip to Nepal is relevant.
check to see that under the listings "network" and "carrier" the same name appears. it should be that name of your carrier. if they are not the same then the phone is not connecting to your network for data. if this is the case then go into...
enable "data roaming" and "3G"
if this is not the problem I'm out of ideas
same issue here. did you have any luck fixing it? i'm on o2 UK, haven't touched a thing!
when i reset to factory defaults it starts working again. but the second i restore the backup (even before i install any of the apps - this is the base backup restore including voicemail + sms + settings i guess) it stops working again.
looks like i'm restarting from fresh.
Yeah, me too. I am a AT&T user that is subscribed with everything they require. I have the iPhone 3G and just now (for no apparent reason) I cannot connect to the internet via my service provider. I was literally using my 3G internet capability (got to love Pandora) less than four hours ago. However when I attempted to listen to some more just now, I found that my 3G was unavailable. All of the problems the original poster described is true for my phone as well. I have restarted 3 times, turned it on and off (in case somehow it would react differently), and I have restored it through iTunes. I am even running the current update. I am at a loss and I really want to fix this because I honestly listen to Pandora aprox. 4 hours a day. Also, the last time I restarted it, my phone froze and would not let me do anything until i connected it to my computer. I am so confused please someone come look at this and help me (us) out.
Hey guys. I stumbled upon this forum as I was experiencing the same problem. Nevertheless, as I was reading the discussion here I also restarted my phone and it now works. I think the phone probably did change networks and couldn't switch back. Restarting the phone seems to have cleared that up. I hope that helps.
I too are experiencing the same problem on a 8gig 3G Telstra Australia iPhone that was bought outright. I also have another (same) iPhone and the settings on both are identical yet the new phone refuses to connect. I have tried a few ideas/suggestions including: settings, general, network, cellular data network and changing it from telstra.iph to telstra.internet. this works but I think something is wrong because to .iph refers to iPhone (I have switched it back until to confirm with telstra about this).
I have also tried settings, reset, reset network settings but this did not help but has worked for others.
I have also tried turning off the unit and taking out the sim card and restarting the iPhone but again no luck yet.
I plan to speak to both Telstra and Apple to see if this problem has a simple solution and will post a new thread titled "solution to cellular network problems".
Personally by all the trials and errors so far I believe it is a carrier problem and having to re-enter the pin on this phone everytime I re-boot it suggests it could be sim card related.
I have this problem on O2 in the UK on a pay and go deal...the settings change on their own to mobile.co.uk (ie the contract setting) from payandgo.co.uk
Its happening more and more sometimes 4-5 days now
I go and change the data network settings and sometimes it sticks, sometimes I have to restart, sometimes I take out the sim and put it back in...no one things works.
Hi guys i also had the same problem you are having with my iPhone 3G on 02. The only way i found to solve it was to reset the network connection on our phone.
To do this go to: Settings>General>Reset>Reset Network Settings.
Your phone will then shut down and restart and it should then be able to connect again.
Hope this helps
Hi, I am just having the same problem .
I bought my iphone in Italy and now i am in New Zealand.
