what Is Wrong With My Sms

I hate to ask you this, it seems like a canned response that you'll see over and over again here... Did you try to reboot your phone?

I also see that your phone is saying no service. Are you sure that only your texting is broken?

There might be an update from your service provider that needs to be installed (and that is also what I'm gathering by your screenshot).

Try this link:

Manually update your carrier settings on your iPhone or iPad - Apple Support

I hope that this will help you ;-)

Step 1→If you see No Service, Searching, or SOS on your iPhone or iPad

Step 2 If step 1 doesn’t resolve it:

Go to Settings/General/About and look at Modem Firmware. Is the entry blank? If it is you need to reinstall it by restoring the phone to factory settings, then restoring a backup. Back up the phone first, of course:

1. How to back up your iPhone, iPad, and iPod touch - Apple Support
2. Restore your iPhone, iPad, or iPod to factory settings - Apple Support - follow the instructions to restore using your computer, do not using Settings/General/Reset (which is not included in those instructions)
3. Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

If the modem firmware DOES have a value you may have a hardware problem. The first step is what I just posted, but after that you need to contact Apple support using the Get Support link at the top of this page.

Start here:

You need to have a good Service & Wi-Fi.

Charge the battery > 70%.
