iPhone 5 No Service Issue

Have you tried resetting you network settings? Settings>general>reset>network settings.

I have T-mobile and when there was a carrier patch introduced, I missed it. I wasn't recieving LTE until I did that. You check for carrier updates in the settings>general>about section. One will just pop up, but id still do a fresh reset on the network settings.

Thats my only guess

Since you didn't tell what troubleshooting steps you took, if any, do the followning steps:

1. Reset phone (no data loss): press both home and power buttons for at least 10 seconds, releasing when the Apple logo appears.

2. Settings > General > Reset > Reset Network Settings

3. Replace SIM card from AT&T

4. Restore phone in iTunes using a backup

5. Restore in iTunes as new, without using a backup.

6. Warranty service from Apple.

Well its ATT I believe. Its weird dude haha....I have a similar issue. I have LTE now wherever I go EXCEPT my house. It constantly switches between 4g and LTE only in my house. Could just be the specific area your house is in. Sorry Goodluck

Yeah because its the only LTE Iphone in your house. Its another band to switch between thats why. You can try turning LTE off when your at home. Its one less band it searches for.

Im assuming you have WIFI so LTE is pointless at your house for voice

Yeah Id turn off LTE then when your home. Tower upgrades are happening all across T-Mobile and ATT so thats a good thing. Maybe it will improve in the near future. Make a habit of checking the about section for carrier upgrades. I do it now too since my experience. Goodluck

I have been facing similar problems with my Jan 2013 Iphone. I get into a lift, it goes to No Service. When I am out, it does not automatically reconnect. All kinds of resets and updates etc. were done to no avail. I have to switch on Airplane mode and then switch it off.....then it starts searching for the carrier and connects.

Only saving grace with IOS 7 is u can quickly access the Airplane mode settings.....

I believe many are having similar problems all over the world.

Hope Apple comes out with a quick solution.......I am hugely disappointed....

I don't think it's an Apple issue dude. It's carrier. Me 2 before, but with recent carrier updates and continuous tower upgrades, I have LTE everywhere since my last post.

Its not a carrier issue. The sim works fine in my old Nokia....

Sorry. My iphone 5 didn't have any issue not connecting it just wouldn't be LTE. All I will say then is try resetting network settings or restore your phone and try again. The reason why I said it's not an apple issue, is because there would be more publicity on it. Here people come for issues out of the millions of iphone 5's sold. There's a few small threads on a similar thing, but that's it. Not many on other sites either. It's not a widespread issue. So I think you would have better luck talking to your carrier.

I'm not defending Apple either. I'm just suggesting what I would do. Remember the iphone 4 antenna problem? That was Apple :) Goodluck

I agree it's not a carrier issue. I experience similar issues, but only when away from home. In our household we have two iPhone 5s and one iPad mini all with the same carrier (AT&T). When all of our devices are together, my phone is the only one that constantly switches from LTE to E to 4G to no service. It's to a point where I have to carry my iPad whenever I travel in my car because my phone is nearly useless for GPS.

So I finally took my phone to the the Genius Bar. Nothing came up on the diagnostic test and the techs were a little stumped. They surmised it was probably an antenna problem. Anyway, I have a replacement phone now and it's working beautifully. I think this confirms that it wasn't a carrier problem. I'm a very happy camper now.
