I am getting an iOS system error:

Could not activate cellular data network

Turn on cellular data or use Wi-Fi to access data.

while I'm not connected to Wi-Fi and I'm trying to use any apps that need a data connection. Cellular data is turned on, and I'm not in airplane mode or anything. LTE was working just fine yesterday.

I have tried Settings > General > Reset > Reset Network Settings with no success.

In case this is relevant, details from General > About:

  • iPhone 6 (Verizon; MG642LL/a)
  • Carrier: Verizon 25.1 (I'm subscribed with PagePlus MVNO on Verizon's network)
  • iOS: v10.0.2
  • Modem Firmware: 5.24.00

Is this likely a problem with my phone, or with PagePlus? How can I resolve it? Thanks!

  • There's a few similar questions about this. See if this answer helps. It's not a direct duplicate but it's similar.

  • Thanks. Unfortunately the menu path described there (Settings > Carrier) doesn't even seem to exist anymore. If you read his update, he says even that appears not to have fixed his problem. Does lead me to believe this is a carrier issue, though.

ETA: Go to ivzwentp.tracfone.com and install the configuration profile. This fixed the problem for me. (That's what the text I got last week instructed me to do. I was able to find a copy of that text online, at a different site.)

Same problem here, also on PagePlus. I've tried to chat with PagePlus customer service but have been unable to get through. I did get a weird text message last week about iPhone data issues on PagePlus - maybe that was related? I thought it was spam so I deleted it...

  • Yeah, I just got a message from them with the same link. It feels really shady though--they want you to install a cellular configuration "Profile" (I had never heard of this--I'm not well versed in cellular networking stuffs)--but iOS says the profile PP linked to is unsigned, which feels really questionable. Not sure how much of a security risk it is to install something like this. And yet, it did get LTE working...

  • I get new profiles from AT&T after almost every major iOS release so the 'process' of installing a new profile is ok. I can't speak to the validity of the link you received, only you can do that.

  • Do the AT&T profiles you install say "Not Signed" in red text? This one does. That's the part I'm more worried about. If it's not signed, I am much less confident that it isn't malicious, and apparently from reading up, configuration profiles can give third parties a lot of control over your phone.

    Yeah, it's not signed and it's over a non-secure http channel. This caused me not to use it for a while until I was desperate and just did it. I figured I could wipe my phone if there was an issue. But it fixed the cellular non-data issue. I have the same URL as was posted here.

I have finally got this working. As noted above, my problem initially was the opposite of the OP. I wanted to remove the cellular data (APN profile) when I travel, then restore it when I go back to the US.

There are two parts to the solution, each covered elsewhere in more detail. Here is how I put them together.

  1. If Tracfone/Verizon has pushed a profile onto your phone with iOS 11, it will be hidden and cannot be removed. You have to backup and then edit your backup with iBackupBot. (This is described elsewhere.) The simplest edit (and the only one that worked for me) is simply to remove the profile file. "mobile/com.apple.managedCarrier.plist" Then still using iBackupBot, you do a full restore including reboot. The result is a restore with all your data, etc. intact, but no profile installed. After I did this, my foreign SIM worked fine with cellular data.

  2. Although I am not back in the US, I did go to the iphone.flexserve.net site where, as Aaron suggested above, I installed "Straight Talk (tracfone.vzwe...)" as my profile. Of course, my French cellular data immediately stopped working. However, in Settings, General, I now see the Profile and this one can be removed. I did that and Bingo, French cellular data is restored.

Unfortunately, this is a solution for techies. The good news is that you only need to do the backup, delete profile from backup, and restore once. After that, you have an easy way to delete the profile and then reinstall it.

I think it will be important to install the profile immediately on returning to the US, before Tracfone/Verizon pushes out another hidden profile. Then refuse all proposed carrier settings updates.

Also, who knows if this will keep working when there is another iOS update.


For what it's worth, below is the email I got back from PagePlus technical support. Installing the configuration profile worked for me, but CAUTION, iOS says that the linked configuration profile is unsigned which means that we can't be confident that this is the exact file PagePlus intended us to download. Theoretically, a malicious hacker could swap it out with their own file, and do bad things to our phone once we install it. So proceed at your own risk!

This configuration profile from PagePlus is NOT signed

Here is the help I got from pageplus to get data back for my iphone 5s:

"Please turn on your WIFI, open Safari and enter ivzwentp.tracfone.com, Accept the changes to install the new profile."

I installed the profile even though it is unsigned, since the link is provided by customer service people directly.

    I wouldn't install any profile that's not signed.

  • @fsb reasonable, but it's a dilemma: install profile or lose cellular data on PagePlus

After weeks of my tracfone not working, I finally found an answer with tracfone customer service. Go to iphone.flexserve.net. Select APN & Proxy Changer, Enter your country, then for operator, select "Straight Talk (tracfone.vzwe...)", then click "Generate Profile" and install the profile. Turn your phone off and then back on. If that doesn't work, try Verizon (4G LTE) as the operator.


I just followed Aaron's suggestion: Go to iphone.flexserve.net. Select APN & Proxy Changer, Enter your country, then for operator, select "Straight Talk (tracfone.vzwe...)",

I wanted to add that I use Tracfone (over Verizon network), not Straight Talk, but this solution worked perfectly for me on an iPhone SE that a month or so ago had started having the problem: “Could not activate cellular data network”

  • Now I have the exact opposite problem. I am in France and need to remove the Tracfone/Verizon APN settings in order to get cellular data from my provider here. Since iOS 10, the APN profile is hidden. I have found no way to remove it except with a Reinitialize to factory settings. You cannot then restore from an iTunes backup because it will just restore the problem APN. Reset network settings doesn't help.

I have had this same issue on my iPhone SE. I use tracfone and I bought a 200 minutes card yesterday. It added the minutes and data and texts into my account but then my phone could not use data. I had plenty of bars of signal and it showed Verizon LTE (I have the cdma tracfone card). I had to call tracfone several times before someone there could help me but it is resolved now. They had to update something and the rep asked me the MEID number and IMEI number from my phone plus my sim number. It took about 30 minutes once I reached a person who knew how to fix this. Also this has happened to me a couple times before. I love having affordable service on an iPhone so I will continue to deal with this inconvenience. Also I do NOT believe this is an issue with the gsm sims but the CDMA has much better signal strength where I live.


I had same issues but then found this out took me a week but now my data works go to https://iphone.flexserve.net and select Verizon 4g not tacfone profile and you should be able to use your data.


This is what worked for me, which is a bit different than what's already posted: I did a full DFU mode restore to the latest firmware, set up the phone, factory resetted it (settings > general > reset > 2nd option from the top), set up the phone again, did a Cellular Data toggle first off then on (settings > cellular > cellular data OFF/ON), and finally the web started working. There was no need for any additional profile download, and it worked perfectly with both Verizon and PagePlus sim cards... your mileage may vary.


I used these steps as suggested:

I also got the dreaded "Could not activate cellular data network" on an iPhone XS with iOS 14. I tried toggling Airplane mode, Cellular Data mode, restarting phone, reset network settings, none of those worked.

What finally worked was to change the General > Cellular > Network Selection from Automatic to T-Mobile (or whatever your provider is). After that, the cellular data worked perfectly fine.


I had the same problem in December and that is what Tracfone told me to do as well. It works. I will say I seem to have this issue every time I add data to my phone.

Ok. Here is how I fixed my no data problem with Tracfone and iphone 5se.

  1. Put the Tracfone sim in an iphone that the data works in. (Iphone 6 and above). Be sure the data is working in that newer phone.
  2. Backup the newer phone on itunes.
  3. Re-set the phone and all settings on the iphone 5se.
  4. Restore the iphone 5se with the back-up from the newer iphone.
  5. Re-start the iphone 5se
  6. Once the iphone 5se has been re-started, go into celluar settings and turn Cellular Data "Off" and then turn back "On".
  7. Turn wifi off. check to see if cellular data is working. It should be.
