What could be done to solve the problem?

Try settings/general/reset/reset network settings. If that does not do it then contact your carrier

In that case the procedure assuming it is a PAYG phone is to get an o2 PAYG sim, put £20 on it and then make a few calls making sure you leave £15 on the sim to pay for the unlock. Then there is an online unlock request form on the o2 site just fill this in. It takes between 1-14 days and you get a message from o2 telling you how to complete the official unlock through iTunes.
I got my o2 unlock in nov 09 so this is not just opinion.

I have had similar issues backing up to iCloud. Thy only thing I have found to work every time is backing up to iTunes and then doing a restore to my new device. That includes iPhone 6.

TS1398 My iphone 3G only gets wifi if its within 1 ft of the router. I have had the antenna replaced but its no better.

My iphone 3G only gets wifi if its within 1 ft of the router. I have had the antenna replaced but its no better. I have restored to factory through iTunes but still not working. 3G signal is good

Try these steps. Check to see if your router has a firmware update. Go to the manufacturers website and check. If so, install. If not, reset the router. Disconnect from power for 30 seconds, plug it back in. Wait for it to boot up and then check your wifi.
Do a reset on the phone. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. After the phone restarts, check wifi.
If none of this helps, then make an appointment at the Apple store to have the hardware checked. If it is found to have a hardware defect, they will more than likely replace the device. Remember the final call is Apple's.

Iphone 3Gs turns its self off when i go on to the internet

Hello,
Can anyone please help me my Iphone 3Gs turns its self off when i go on to the internet, especially when i go on to google. When i am on the internet browsing my phone screen just goes blank then i need to turn my phone back on.
This happens all the time and it gets so bad that the internet doesn't turn on and turns its self straight off.
Thanks

You need to go through the basic troubleshooting steps as described in the User Guide:
Restart phone
Reset phone (press both home and sleep/wake buttons until the Apple logo appears.
Restore phone in iTunes using a backup.
Restore in iTunes as a new iPhone, without using a backup.
BTW, are you really still using long obsolete iOS 3.0 as your profile states?
Is your phone jb or hacked? In that case, SOL.

I cannot get phone signal when abroad

I have an iPhone 4S and cannot get a signal when out of my home country. Is there a solution for this by changing the phone settings?

Did you enable international use with your carrier before you left? If you did, check Settings>General>Network and make sure that Roaming is turned on.

My iphone 3Gs only has wi fi access within 1 to 2 meters from router

My iphone 3Gs only has wi fi access within 1 to 2 meters from router. It had been working normally for the last two years. I changed wifi modem a couple of months ago but still worked fine until a couple of weeks ago. I have the same problem with other wifi networks. The iPhone only picks them up if it's within 1 to 2 m of the box.
I've tried turning the phone and the modem on & off, restoring the phone and different wifi networks - no change, still has the same problem.
Can anyone suggest what might be wrong or what I could try next?

These are the symptoms of a loose or detached Flex Cable # 6 at the top of the Logic Board.

If you mean the hexidecimal equivalent of the alphanumeric password, then you can find this via the AirPort Utility, as follows:
AirPort Utility > Select the AirPort > Manual Setup
On the AirPort Utility's menubar select Base Station > Equivalent Network Password
