subject: How to do an iPhone Repair [print this page] The iPhone 4 is not known for taking great phone calls. The iPhone 4 has recently been criticized as a result of some dropped calls and antenna problems. It isn't unusual for the iPhone 4 to have No Service listed. However, the No Service phenomenon is not unusual regardless of what type of cell phone you are using. Here are some ways to repair the problem.
There really isn't a problem with the iPhone's antenna and it is not easy to repair. Rather, you should try to troubleshoot these iPhone 4 antenna problems. The easiest way is to adjust the way you are holding the iPhone 4 so that you don't have a tight grip on the lower left hand corner. You also need to use the free Bumper case that was offered to iPhone 4 consumers.
If you are not getting any service there are some things that you can try. The first thing to do is to double check to ensure that your iPhone 4's Airplane Mode is on. If it is you will get No Service on your iPhone 4. You will probably have to wait as long fifteen seconds after turning the Airplane Mode off to have iPhone 4 services again. If that doesn't work, try pressing the Sleep and Wake button a couple of times to see if that repairs the problem.
If nothing so far has fixed the problem, you may be out of your general service area. This is not as common as it was in the earlier days of cell phones, but you still can get into regions where you may lose service altogether. If this happens consistently then you need to contact your service provider to determine your data plan and preferred, but there is little that you can do in the meantime to repair the No Service reading on your iPhone 4.
There may be times when the No Service message on your iPhone is the result of problems with the 3G network. There is an easy way to troubleshoot this. Begin by going to Settings and choosing General. From here go to the Reset option and then select the Reset Network Settings option. Next, enter your password at the prompt. After you have reset the network settings your iPhone 4 should only take a couple of minutes to restart. After it has come back your Iphone 4 and 3G network service should return.
