3G is not working after upgrade to iOS 9.3

Tap Settings > General > Reset > Reset All Settings

Then restart your iPad and see if you have 3G.

If that didn't help, tap Settings > General > Reset > Network Settings

Then restart you iPad one more time.

I have removed my sim card and then put it back in. Fixed it for me.

I Have the exact same issue with my iPad. I tried both remedies listed here, and neither helped reestablish a cellular connection. Frustrating!

Same here, tried all remedies, none seem to be working. Apple needs to do a through beta check of all iOS upgrades before releasing them, can't have working devices getting rendered inoperative. 😠😠

I initially had the same result when I removed/restored the sim card after shutting the iPad down. When I re-tried the sim card replacement using the following steps - Success 🙂 :

• Remove sim card while iPad is switched on
• Shutdown iPad
• Return sim card after shutdown
• Restart iPad

Hope this helps.

Glad this worked for your iPad. I followed your process and unfortunately it did not work on mine.

Same here, no success with the restart, hence have downgraded mu iOS to the previous version 9.2.1 , and everything is working fine. So the issue is with iOS 9.3, not enough testing before releasing it.

After trying all the suggested solutions with no success, I've opened the 'carrier' tab and deselected the 'automatic' mode. This immediately solved the problem, after that I've reselected the 'automatic' mode. Hope this may help.

Faced the same issue. solved it by removing and reinserting the SIM Card. However, after restarting the iPad 2, it shows No Service again.

I do, however, noticed that after the latest update for iPad 2 to 13E236, the "Mobile Data Number" has become "Unknown".

I tried removing the SIM and re-inserting, and yes the 3G service was restored for my iPad 2 after re-start.

However after a second re-start, sure enough, the "No Service" message returned. A quick pop-out and back-in of the SIM got things going again, but it sure is frustrating! And yes, I rarely "hard" re-start the iPad, so I guess I'm going for a while at least until Apple get the 9.3.1 / 9.3.2 out that fixes this little mess.

I Have this same problem on iPad 2 since the 9.3 update. I haven't found a solution but I have found a way to get the cellular network back. But if you power off and then power on you will find it gone again and you have to redo the following work around.

1. power off and remove SIM card. Then power back on and it will ask for SIM card. insert sim and it should find the network. This is simple but if you have a case it is a nuisance to keep pulling it apart.

second workaround.

1 Go to settings and turn cellular (mobile) data OFF.

2 Turn Aeroplane mode ON.

3 Power off iPad.

4 Wait about a minute. (Not sure if this is absolutely necessary)

5 Power iPad on.

6 Turn Aeroplane mode OFF

7 turn Cellular Data on.

you should then see a cellular provider box pop up under the Cellular Data box and the it should search and find your network.

this works on the iPad 2 and hopefully other iPads.

I Noticed heavy battery drain under 9.3 and when I ran my iPad in the No Service condition, battery usage improved dramatically.

good luck.

I updated my iPad 2 to IOS 9.3 last evening and immediatly noticed I lost 3G. No Service replaced 3G at the top left screen. Based upon a suggestion I read in this forum, I pulled my AT&T SIM card while the iPad was on, dropped it on the floor and found it a couple of minutes later. I re-inserted and immediatly the radio went into "Searching" mode. It found the network in about 15 seconds and so far all is good. I'm not sure if dropping the SIM card on the floor is essential, but it did make me wait a couple of minutes before re-installing.

This worked for me!

I was puzzled with the issue after the 9.3 update. Even contacted my mobile internet provider.They are not aware of 9.3 issues what so ever.

The first work about from Mikec1951 definitely works. Finally,something worked for me. Thank you, mate. It was driving me crazy for a few days.

I haven't tried the second one but regrettably noticed that every next "Power off" will bring the "No Service" sign back with no further radio signal.

After a few attempts to restore signal I realised that it's a system code bug that should be fixed by Apple ASAP.

I believe there is no stable work around that may last long enough in order to forget about it.

Strange bug, by the way. Never seen anything like this before on Apple products, old or new. Makes my good old iPad 2 useless after 9.3 update.

Common Apple! We still rely on you and your system and software engineers with our old iPhones and iPads.

Add me to the club of iPad 2 users that noticed "No Service" after updating iOS and powering down.

I have no problem accepting that my device is no longer under warranty. I would have no problem accepting that it is "no longer supported".

BUT DAMMIT APPLE!!! WHO DECIDES IT'S OK TO PUSH UPDATES ON YOUR EARLIER ADOPTERS WHICH THEN CRIPPLE THE DEVICES!!!

I am so disheartened/disappointed/angry about this continued practice that I have resisted investing in any new tablet from Apple and I'm seriously considering moving over to Android for my next tablet.
