Reset the iPhone:
It has been observed that simply resetting the iPhone can resolve signal strength issues.
Reset network settings:
In some cases resetting the network settings has also helped so tap Settings, tap General, tap Reset, tap Reset Network Settings.
This will restart your iPhone and will also delete any stored Wi-Fi passwords as well as DNS settings and more.

Place your SIM card again:

If your iPhone’s SIM card is not placed properly, it has been observed that it can affect signal strength.
So a good idea would be to remove your iPhone's SIM card by pushing a straightened paper clip into the small hole on the top of the device to open the SIM tray, then check for debris inside the tray or SIM card slot, remove it by blowing into the slot or using compressed air and then placing the SIM card properly and then re-inserting the SIM tray.
The notion is that improper SIM contact can result in a weak signal, so the above procedure could help.
Attaching scotch tape to the SIM card:
This is indeed the most ingenious methods, it appears that attaching a small piece of scotch tape to the outer side of the iPhone’s SIM card (the side of the SIM card that does not have metal contacts) can result in a surprising boost again borrowing from the notion that improper SIM contact can result in a weak signal.

Up graded to 3.1.3..now i cant get a signal..what do i do???My phone was jail broken..but like i said no signal so i cant make any calls now.


Updating to official 3.1.3 will lose your unlock, possibly forever.
You can't downgrade. Lesson is never upgrade the iPhone without checking that the unlock works on the new version.

Need to unblock a c905


The answer is that there used to be a connection before O2 and Vodafone started blacklisting handsets! Orange and T-Mobile have been blacklisting handsets for a long time (It is only recently that O2 and Vodafone also started blacklisting handsets).

NB Orange & T-Mobile always lock their handsets!(e.g. an Orange handset will only accept an Orange SIM and will not accept an O2, Voda or T-Mobile SIM)

So if you reported your Orange or T-Mobile handset missing to your network it became barred/blacklisted! BUT it was only barred on your home network. Therefore unlocking the barred handset would enable it to work on every network except the one it was originally locked too! Therefore the phone still had some commercial value, as it would function on at least 3 out of the 4 networks.

It wasn't long before Orange and T-Mobile began to combine their individual blacklist databases. Therefore a phone barred on Orange was also barred on T-Mobile and vice versa. Even at this point the barred handset could be unlocked and used but only on 2 out of a possible 4 networks (O2 & Vodafone).

The government eventually stepped in and forced O2 and Vodafone to update their systems and introduced the CEIR. Now that all the networks share a central blacklist database, even if a barred handset is unlocked it still remains useless on ALL UK networks!


Hope that helps.

Iphone not picking up signal from carrier


If you can do a full restore back to factory settings (re-locked? I don't know if you can even re-lock it... lol.. I haven't unlocked mine) and see if that works. If not, you may have an issue with the antenna/receiver unit in the phone. Apple should be able to verify the issue.
