My iphone 4s keeps on searching for network. Initially i thought there might be a problem with the SIM i use. I tried using my sim in other iphone and it worked.
Other sim, they worked on my iphone. What could be the reason?

My iPhone doesn't connect to my network anymore. I flew from Europe to the US a few days ago and it worked just fine in the beginning, but when I went on the subway and lost reception it didn't come back. A quick restart of the phone worked the first time. Now it happened again yesterday when I went on the subway and the reception hasn't come back since....
The Phone never asks me for the PIN if I restart the phone, even though it should and all it says is "Searching....", even if I remove the SIM it says "Searching..." instead of "No SIM".
I can still use Wifi though!Here is what I've already tried:Restarted the phone several times (both regular and the two-button way)Reset all settings
Reset network settings (twice)Switched airplane mode on/off several times (it was on for several hours over night)Â
I have tried a different sim card of a different carrier, so it's definitely the Phone. I really want to avoid to delete everything.

I bought my ip4s (brand new) on the 19th of January. And it was working fine up until last week when it stopped detecting wifi networks When I turn on wifi the "finding networks" circle keeps on searching with no success even though I used to connect to same router before. I tried everything: resetting network connections, rebooting phone. I even downloaded the latest iOS software just now. The problem seems to persist and to add to that the battery is being drained quickly even though I already turned off wifi (so it ain't still trying to connect).

As soon as Iphone had water contact, turned off immediately and backed on after 3-4 hours. Turned on in the evening on the same day. Everything works like camera, sound, wifi, imessage etc., except does not connect to ATT network. Took it to att store and tried changing the sim. No use. Took to apple store, explained had water damage, so they tried to restore. The whole installation takes place. Then the initial set up screen starts showing to choose country, language, connect to wifi. After that it tries to activate phone then displays message saying that phone is damaged and cannot be activated. I just want the phone to be same as when I took to the store so that at least I can use it as ipod.
The software seems like it is not allowing me to use the other features of the phone and only does if I am able to connect to the network. I had been to att store as well and told that I am not changing my plan or breaking the contract but we buy a new phone and continue with att. Since as a owner of the iphone I should be able use the other features though it is not able to connect to cell phone provider network. How to bypass the activation step and takes me beyond that point so that at least I can use it as ipod. Looks like apple software is restricting the use of the other features of the iphone if not used for making calls.

My iPhone 5S is about five months old and the network constantly disappears into "Searching...". I've done everything from restarting my device, to a hard reset, to a network settings reset, and even replaced my SIM card but I'm still plagued with the problem. It's not got to do with the network, because that seems to be working fine for everyone else in the country.

My iPhone 4s drops network services and keeps searching for about 2 hours and then starts working again. I reset all the settings etc and makes no difference to it and still won't work. Checked the sim and network and there are no issues with it.

My blackberry curve 8530 for metro pcs keeps shutting off by itself (very frequently) and taking like 5 minutes to restart. I factory resetted the phone and it is still doing it. I tried to update it using the Desktop Software but it would not even connect, it would just charge it. Also, I went to setting and memory and prompt when connecting, and it still did not work. Also it keeps going in and out of service, when I know I have service, it says "Searching for network".

I recently updated my blackberry software. EVerything worked fine, I has no problem updating. When I put my new sim card in (brand new sim, never been used), my phone registerd me on the verizon wireless network, even though I am livning in south africa with a south african sim card. I can send sms and make phone calls, but that it is! Before I did my sim swop and system update, everythin worked fine on this phone. I cant bbm, use the internet etc etc.I have tried everything. Tried to resend registerstation message, manually connected to 3G vodacom network and resent registration msg. I have called my service provider. I have rebooting. I even tryed restoring data from a recent backup i did when my phone worked, and that did nothing. EVERYTHING, and im on my final straw. I just want a working phone.

Myspace account stopped sync and updating in the happenings. so like twitter, I deleted my account and re-added, but now I cant re-add my space account at all! It keeps giving me the message "Your entry is invalid, please try again."I keep trying it everyday but no use. It also disappeared from the status bar (where i post my happening status to social networks). Why can't I re-add my myspace account? it worked before resetting the phone. everything works fine and all other social networks like twitter, orkut and facebook work fine ,but not mypace. I tried logging in to myspace from a PC and my login worked fine. I even created a new motoblur account but no use.

I upgraded to a new Bold 9900 in November with T-Mobile, and went to Dubai for winter vacation in late December. I frequently visit there and have a local SIM card, and previously I used an unlock code from the internet to unlock my old Bold 9700 so that it accepts the Dubai SIM card (and for the past year and a half I been using this unlocked Bold). I tried doing the same thing like I had done before this time around with my new Bold 9900, but like an **bleep** that I am, I used up all ten MEP code tries with the device, and now the phone network is blocked. Every time I put in either the Dubai or T-Mobile USA SIM card, it says on the top "Invalid SIM Card". Also after rebooting, it always asks me that I need an unlock code to unlock the card, but when clicking "yes", it just does not do anything, same thing goes with clicking "no." Now that I am back in the US again, the US T-Mobile SIM card still does not work with the phone. If anyone knows what the right procedures are to go about getting my blackberry working again and getting the network block to go away so I can start using my T-Mobile SIM Card?when I go to the SIM Card settings on the device, it reads: SIM: Disabled Network: Blocked Network Subset: Disabled Service Provider: Disabled Corporate: Disabled Once again?

Just got my Bold for Christmas and it's just been the greatest phone I've had so far. I decided to leave the OS as is (5.0.0.423) and only installed apps I would actually use (Google Maps, Trapster, ScoreMobile, Poynt, QuickLaunch and WeatherEye as well as the Bottom 8 theme). Everything worked amazingly on my phone until 2 days ago.
Sometimes (7-10 times/day) when I dial a call it says "Calling" for about 20 seconds then says "Call Failed". Sometime I have to retry up to 6 times to be able to make my call. Very frustrating.
My next issue (that appeared almost simultaneously with the 1st one) is that I literally just loose the network. The phone will say "Searching for network" for 4-6 minutes then find it back. So many calls missed and frustration !!!!!
Now to help anyone that might have a solution for me here are some facts:
- I own a Bell unlocked 9700 (using it on Fido network)
- OS v5.0.0423
- Only installed apps and themes are listed above
- My SIM dosent seem to be loose in its slot (one of my older BB's had that problem, cardboard fix!)
- My wife is on the same network with a BB Pearl Flip and dosent loose the network

I am on vacation, and for some reason just had to update my iPhone 4 to the new update 4.1. Well guess what, it will not update!!!!
My itunes is the latest one, so I even deleted itunes and re-installed it, restarted my computer and iPhone, then tried to restore it again. No go. At first itunes was giving me a 2002 error, now I believe it's something like 1004 error. What can I do? There is no apple store where I am located.

I need to find a good App that evaluates how well various chargers/USB cords are charging the G4 but haven't found one yet. The "Galaxy Charging Current" App worked well with my S4, but doesn't play well with the G4. I've also tried several at the top of the Play Store list (Ampere, OPO Charging Current) but most give very erratic mAh readings.
