    It is not a new phone...it is one of the original iphones. I have not dropped it, and the SIM card is clean. I just had the SIM card replaced (so i had to reactivate it) and I still get no service. I did activate it using an authorized carrier. I thought replacing the SIM card would help and I was told it would, but no dice.

First, is this a new phone that came with this issue? If not, how long is the phone? Did you drop the phone at all? Try looking at your SIM, the section that has copper plates should clean and free of debris. Also confirm whether you are or are not unlocking and using an Apple authorized carrier (I'll be able to help in either circumstance).

Iphone 4s no network coverage at home


By no network coverage do you mean no cellular signal or can't connect to your home wifi? If wifi trouble push settings button on iphone. Select and turn on wifi. It will search for available wireless networks. Choose your home wifi, should be the strongest signal, most bars. If you don't know your ssid , look on the sticker on the modem. For instance ssid at&t 2345. Once you select your ssid you need to enter password which is also found on the sticker on modem. Enter password and select join. You should now be connected to your wifi. This will always reconnect automatically when you leave and come back home. If not wifi issue, are you just too far from cell tower to get good signal?

No signal bars on my iphone 3gs 16 gb


first try turning airplane mode on for a few minutes, then back off. its found on the first page of the settings menu near the top. It will cut the link to the cellular network completely, then rebuild it from scratch. I'd say give it at least a few minutes of down time.
if that doesn't work, try a hard reset. hold the power button on top along with the home button until the phone turns off and reboots, then let go and look for service.
if that doesn't work, update your iphone to the latest software. New software frequently contains updates to the software responsible for connecting with the cellular towers.
if no luck thus far, you're destined for the genius bar I'm afraid. good luck

I forgot my iPhone Passcode. What can I do to unlock it?


iPhone setting:*
- Auto-Lock: 1 Minute;*
- Passcode Lock: On, require passcode immediately, after 15 min or 4 hours etc;*
- Network: Turn 3G Off

Scenario 1: Home screen is active with screen on*
1. Press power button for seconds until asked to '"slide to power off"
2. Slide to power off
3. press power button to turn on iPhone
4.*When asked to enter passcode, touch the "Cancel" key, then slide to unlock
5. bypassed passcode

Scenario 2:*
1. On the screen of being asked to enter passcode, press power button for seconds until asked to '"slide to power off"
2.*Slide to power off
3. press power button to turn on iPhone
4.*When asked to enter passcode, DO NOT touch any key on the screen, press power button for seconds until asked to '"slide to power off"
5. Slide to power off
6. press power button to turn on iPhone
7.*When asked to enter passcode, touch the "Cancel" key on the right bottom corner, then slide to unlock
8. bypassed passcode

Notes:
1. When Network setting changes to Enable 3G: ON, "3G" signal shows up, passcode CANNOT be passed through
Go to a underground parking lot or a lift where 3G signal is weak, when 3G signal switches to "E" (Edge), passcode CAN be passed through following above steps
2. When no 3G or Edge signal, above steps don't work

Conclusion:
Seems passcode security is related to network status
Possible security hole under Edge

Ii got a unlocked iphone had signal for the first hur or too now has none even tho it says orange has no bars and cant txt or call or recive


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.
