After the release of iPhone 4S, Apple missed out many things to fix in the iPhone 4S. One of the most important thing that Apple missed out was Battery Drainage issues. The issues are persisting form iPhone 4. When iPhone 4S came in the hand of consumers, Apple released an update to address the battery issues in iPhone 4S which was later on said to be not working on iPhone 4S. So Apple is now working to fix the Battery issues in their new update of iOS 5.1. iOS 5.1 beta 2 was released few days back. No new findings, other than few wall papers were added were found in the new Beta.

Soon after the release of iOS 5.1 Beta 2, Apple released iOS 5.0.1(9A406)r2  for iPhone 4S users. The new release was mysterious until we came across the news that, the new build brings NO SIMIssues fixed in it for iPhone 4S users. From Apple’s new support document:

In certain situations, iPhone 4S may have difficulty recognizing a micro-SIM card, resulting in the following behaviors: 

- “Invalid SIM” or “No SIM Card installed” alert appears intermittently. 
- Status bar displays “No Service” or “Searching” in a location with good network coverage.

Now those of who you are/ were getting SMS issues on iPhone 4S can proceed further to do another step. The solution is really simple and it was founded by me after many hours of search in the iPhone 4S and iPhone 4. The issues that iPhone 4S people are facing is that they cannot send an SMS to any one. The issue is most popular in Pakistan and might be in some other countries as well.

I came across this issue on more than one iPhone 4S. I tried restoring and doing everything but still the issues were there regarding SMS on iPhone 4S. So if you are one of those facing SMS issues on iPhone 4S and need to resolve them for free of cost and it doesn’t requires any hard knowledge or skills, pc or mac.

So feel free to follow the guide below:

Steps to follow:

Step 1:

The main issues is that SMS are failed while sending. It doesn’t matters if you try again or not. The SMS won’t go You can reset the network settings and try anything you want to. The issue will persist.

Step 2:

Now the findings made by me were that the issues are not with the firmware or your network. Everything is fine. The only problem is My Number.

The “My Number” on your iPhone 4S is the main issue that causes the SMS failure. As you can see that “My Number” got 00 00 which is not supported by the iPhone 4S.

Step 3:

Now to solve this issue on iPhone 4S, simply edit the My Number section wit your own number. Like I have done it.

If you cannot edit “My Number”, then do a fresh restore on iOS 5.0.1 and try again. The restore will allow you to edit the My Number Section.

Step 4:

Now you are all done and no need to do any hard work or any further steps. Simply resend the SMS and this time it will work.

Thats it. now you are done free to SMS. Your SMS issue is solved now.

Some times the iPhone 4S auto detects “My Number” and sometimes it fails to detect your number. The issue is found mostly in iPhone 4S, where as iPhone 4 works like a charm and got no issues of SMS or so.

If you think that I am wrong regarding this SMS solution, So delete the number from “My Number” from iPhone 4S and try to send an SMS. It will be failed. Do comment below if you like my findings and do share with other people to support me and to help them to fix the issue.
