    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).

How can I turn off the busy signal on my phone?


Check your iPhone settings
  1. Turn airplane mode on and off. Tap Settings > Enable Airplane Mode, wait five seconds, then turn airplane mode off.
  2. Check your Do Not Disturb settings. Tap Settings > Do Not Disturb.
  3. Check for any blocked phone numbers. Tap Settings > Phone > Blocked.
  4. See if Call Forwarding is turned on. Tap Settings > Phone > Call Forwarding.
Update your software
  1. Check for a carrier settings update.
  2. Check for an iOS software update. Some updates might require a Wi-Fi connection.
Remove and reinsert your SIM card If your iPhone has a SIM card, remove the SIM card, then reinsert it. Update your Preferred Roaming List (PRL) The PRL determines the cellular towers that your iPhone uses for cell service and selects those with the best signal strength.
  • If you're on the Verizon network, dial *228 and select option 2.
  • If you're on the Sprint network, dial ##873283#.
Contact your carrier When you contact your carrier, check the following:
  • Your account is set up to use your iPhone.
  • There aren't any localized service outages.
  • Your account doesn't have a billing-related block.
  • Your calls don't have errors on the carrier system.
Check your network settings
  1. Reset your network settings. Tap Settings > General > Reset > Reset Network Settings. This will erase all current saved settings, including Wi-Fi passwords, preferred networks, and VPN settings.
  2. Try to make or receive calls in another location.
  3. Switch to a different network band. Tap Settings > Cellular and turn off Enable LTE, 4G, or 3G (this option will depend on your carrier and device model).
Still can't make or receive calls? If you still can't make or receive calls, restore your iPhone as new.If restoring doesn't fix the issue, contact Apple Support or take your iPhone to an Apple Retail Store or Authorized Service Provider.

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?

What Type/Brand of router ?????

Apple's iPhone is a multimedia connectivity tool.
As such, the iPhone employs a sophisticated system to keep you connected to the web via WiFi signals so that you can stay up to date with email, mapping and media.
To use the iPhone's WiFi feature just follow these steps.
Tap a network.
If you have not yet used your iPhone's WiFi or if you're in a new WiFi area, the iPhone will show you a list of available networks.
Tap the network that you want to connect to in order to connect.
If there is a password required a little lock icon appears.
Enter the password to connect to locked networks and continue to surf the web.
Monitor your signal.
As you use your iPhone, especially if you're moving around, you should take a look at the signal strength of the connection.
The strength is indicated by a small, black broadcast symbol that stacks arches, or rounded bars, on top of one another.
The more bars there are the better the signal.

Make connecting to WiFi automatic or manual.
The iPhone is equipped to automatically search for available networks and connect you to one.
If you do not want the phone to search for networks, select the "WiFi" option on the phone's menu.
Then select either the on or off option of the "Ask To Join Networks."
Turning this option off requires that you find networks manually.

Forget a network.
Once you connect to a WiFi network once the iPhone automatically remembers the network and connects you to it at a later opportunity.
To forget a network so you don't get automatically connected choose the "WiFi" option on the menu.
Then tap the right arrow button next to one of the networks that the iPhone already remembers. Then tap "Forget This Network" to erase the phone's memory of the network.

Troubleshoot Wi-Fi Connection Problems on an iPhone
If you experience Wi-Fi connectivity issues on your iPhone, you may need to reset the Wi-Fi connection.
Your connectivity issues could be caused by the wrong password if you are having trouble logging into the Wi-Fi network or from a problem in your iPhone's settings.
By resetting the Wi-Fi connection, you are clearing out the previous settings created when you first connected to the network.

Tap the Settings icon on the iPhone's home screen, and tap the Wi-Fi tab.
Swipe the switch on the Wi-Fi tab to ensure Wi-Fi is enabled on your iPhone.
Tap the blue arrow button on the network tab you are connected to in the network list, and tap "Forget this Network."
Tap the "Forget Network" button that appears on the pop-up menu to confirm the action.

Tap the Wi-Fi Networks tab in the upper-left corner to return to the previous screen, and tap the network's tab in the network list to re-join it.
Press the Home button on the iPhone, and tap the Safari icon on the home screen to test the Wi-Fi connection.
Tap the blue arrow icon on the network's tab if the connectivity problem persists, and tap the "Renew Lease" button at the bottom of the network's window.
Tap the "Renew Lease" button on the pop-up box to confirm the action.
Tap the Home button on the iPhone, and tap the Safari icon on the home screen to test the network connection.

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

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.

GPS signal not sufficient on iPhone 3G


Had the same problem with Navigon for the iPhone. I found a simple quick fix:

1. Go to your iPhone Settings
2. Press the General tab
3. Scroll to the bottom and press the Reset tab
4. Press the Reset Network Settings tab

This may take a short time, then after it's done, reboot your device (if it doesn't on its own).
You should now have a good GPS signal!
