I am having this same problem. My phone is basicly useless unless I am connected to wifi. I can't get on safari, send/receive texts, or do anything that needs an Internet connection.

If your phone connects with wifi, but not cellular, you have a bad SIM card. Go to an AT&T store and get a replacement.

Was the other SIM card from your old phone also from AT&T?
It may be the wrong size. Or installed wrong. Get a new sim from AT&T.

Re: My iphone 6 plus could not activate cellular data network

HI,

 

I had this EXACT problem about 2 weeks after I received my iPhone 6. 

 

We had contacted ATT regarding another matter and as ALWAYS they try to switch your plans because anytime they do they get a commission. I was told I would get more data and save $35/month.  They flat out lie to you to get that commission. We stopped getting unlimited data and they charged us $50/mo more.  They do this consistently. Crooks!

 

After spending 3 hours on the phone they changed my plan back with a big mistake. They thought I had and Iphone 4s and an Iphone 5s (my old plan). I called 2 weeks later when I noticed the issue and  after 2 hours with Apple and 3 hours with ATT they said they would get back to me.  I got a text 10 minutes later from ATT asking me to call them.

 

I called them and they said when they changed my plan back they made a mistake. The iPhone 6 will not work on the same data plans as all other iPhones. I don't know the technical details but that was it. They pressed a button and all worked fine.

 

So ATT made a mistake, I spent almost 14 hours trying to resolve it and I have had it with ATT.

 

Never again~

Re: My iphone 6 plus could not activate cellular data network

I had the same problem when I got my wife an iPhone 6. Somehow when they were doing the changeover from her 4S they forgot to transfer the data plan.

Technical Support fixed it for us quickly and painlessly over the phone.

I fixed my problem by creating a new APN for my iPhone 5, because I moved to Fido before a week. I found a online guide about the APN creating and it worked for me.

Re: My iphone 6 plus could not activate cellular data network

Hello Community!

 

We have seen quite a few threads out there over the years regarding customers getting an error "Could not activate cellular data network" or "You are not subscribed to a cellular data service".  The good news is that this is not a problem with your phone, or the network!

 

In most cases it is a simple matter of updating your device information with the network, and you can be up and running in no time.

 

Key factors to resolve this error:

  • Typically occurs on an iPhone when the previous phone was a non-iPhone
  • Must be on an active data plan with AT&T
  • Must have your IMEI updated on your account to the device you are using (if you recently switched phones this could be the issue)

If after confirming that you have the correct device updated, and are on a data plan by going to myAT&T, you can contact us via Private Message for additional assistance.

 

Thanks for all the great feedback and conversation!
