access cellar data

Hey there @raeldredge, we want to help get you connected to the AT&T cellular network on your iPad Air device. 

First, we'd like for you to confirm additional details with us:

• What's the exact make and model type of your iPad Air? This information will help us confirm device specific support for further help.
• What current network stregnth is your device showing in the Status bar? The network signal strength is displayed in the Status bar. The more bars, the better the connection. If the iPad is connected to the Internet via the cellular data network, the 5G, LTE, 4G, 3G, E, or GPRS icon appears in the Status bar.
• Have you confirmed that your celluar data is turned on?
  1. From the home screen, select the Settings app.
  2. Select Cellular Data. To turn cellular data on or off, select the Cellular Data switch.
     • Note: To turn LTE data on or off select Cellular Data Options > Enable LTE switch. Learn more from the Apple support article about cellular data settings and usage on your iPhone and iPad.

Next, you may need to reset your device network settings. You'll need to proceed with doing the following:

• If you are having connectivity issues, you can try resetting your network settings. This will delete all network settings, returning them to factory defaults. From the home screen, select the Settings app > General > Transfer or Reset iPad > Reset > Reset Network Settings > select Reset to confirm.
  

Feel free to reach back out to confirm the following details with us and try these steps. Let us know if this information helped. 

Thanks for contacting the AT&T Community.

Did this work?  I have same issue and did not help

I get the same thing.  Has anyone found a fix?  Reset was no help.

We want to help with a fix to what you're experiencing with your iPad device, @Dwamneff. 

As one of our Community Specialists stated, we'll need to know a few more details to get to the root cause of things. Please provide us with the answers to the questions presented above along with a little more information about what you're experiencing with your device. We're happy to help with a solution! 

It's also important that you're using a compatible SIM card. Your iPad must have an embedded Apple SIM, an Apple SIM card in the SIM-card tray, or an AT&T SIM card.

IPads that use an Apple SIM card:

• iPad Air 2.
• iPad Mini 3.
• iPad Mini 4.
• iPad Pro 12.9.
• iPad Pro 9.7 (has embedded Apple SIM).

We're looking forward to your response!

Same issue I am having and the network reset did not work. I have an iPad Air 4th gen

Hello there @Jtmyob21, we want to shed some light on your iPad Device.

As our other Community Specialist has stated that a new SIM card will help. It's important that you're using a compatible SIM card. Your iPad must have an embedded Apple SIM, an Apple SIM card in the SIM-card tray, or an AT&T SIM card.

Need to get a new SIM Card? 

You can visit a local AT&T store. *Charges may apply.

If you have an AT&T Prepaid account, you can order a SIM online.

We hope this information helps.

I'm receiving the same Invalid Access notification on a 3rd generation iPad that I only use in warm weather months. It's always been easy to sign up for prepaid data in the past, and was functioning just fine when my previous plan expired in late fall of 2021.

I've tried restarting the iPad (several times) and also reset the network settings (twice) without clearing the error message.

I assume that my iPad has an internal SIM rather than a user-replaceable SIM card as I purchased the iPad new as an AT&T device.

My 4g signal isn't exceptionally strong, but I've successfully purchased data before when the device was located in a very low signal area.

Any further suggestions would be appreciated, and I'll happily supply any requested addition information.

Thanks,

Hey there cbrillow, we want to get service to your iPad Gen 3.

Your iPad Generation 3 does have a SIM card slot that you can install and remove. Please try our Troubleshoot and Resolve tool, to send an over the air update to your SIM. You can also try our device support tool, under Connectivity for more support.

If you are still experiencing the same error after trying our troubleshooting tools, then you may need to update the SIM on your device. You can visit an AT&T Retail Store closest to you and pick up a new SIM. 

Please reach back out to us if you need further assistance. Thank you for contacting AT&T Community Forums.

Lorie, AT&T Community Specialist

Hi Lorie,

Thanks so much for your prompt response and (theoretically) helpful suggestions. I did find the SIM and am able to remove and inspect it. (Re-inserting didn't cure my problem...)

I would like to try the Troubleshoot and Resolve tool that you mentioned, but I can't open ANY of the links on the page that opens up -- not even either of the 'Login' links.

The Chat function doesn't work either. I get a 'Loading' message on all the links...

Let's troubleshoot your iPad together, cbrillow.

Let’s meet in a Direct Message to troubleshoot your iPad. Please check your Direct Message Inbox (it’s the chat icon next to the bell icon in the upper right corner of the Forums).

In the meantime, you can use the troubleshooting link from another device.

We look forward to meeting you in a DM to get your iPad activated. 

Thank you for contacting AT&T Community Forums.

Lorie, AT&T Community Specialist

Thank you again, Lori.

I'm trying to follow you instructions, and getting extremely frustrated. I can see your DM indicator if I login on my other iPad, but not when I login on the one with the problem.

Is there any point in trying to troubleshoot on a device that's not connected?

Hi cbrillow, we understand how frustrating it can be when technology doesn't work for us, and we want to help you get yours working.

To answer your question, yes you can troubleshoot from a working device to answer questions about the device you are having trouble with, and hopefully you will be able to access the settings that the troubleshooting steps walk you through on the iPad having trouble.

Please use the DM indicator that you see on your working tablet to communicate with us through a DM. From there we can work with you privately to get this resolved for you.

Thank you for contacting AT&T Community Forums.

Also getting “Invalid Access” error messaging on selecting “Settings/Cellular Data/Manage AT&T Account…”

3rd generation 2017 iPad.

Have continuously been using AT&T DataConnect Pass Plan since August 2018 uneventfully until now.

Per above suggestion in thread changed AT&T SIM card, but without change in the error, at local AT&T store.  Representative there suggested this might be a computer glitch somewhere in system and to come back tomorrow, if not resolved, to prepay the next round of service in person.

We want to help with the error you're receiving, @May_Bee.
