Can't turn on data after travel, iphone SE

[sergi]

Hi,

I recently travelled and used foreign carrier sim card while was abroad. The data settings on my iphone SE were changed to those of the foreign carrier. Don;t really know what was changed.

When I returned to Canada, i could not activate data with my public mobile sim card anymore.
When I open browser, I get the following message: "Could not activate cellular data network. Turn on cellular data or use WiFi to access data"

I re-set all the possible settings but nothing works so far.

- My Iphone SE is Canadian and previously the data worked well with Koodo and Public mobile.

- Cellular data is ON.

- My Public mobile data plan is active and data used well below the limit.

- I did re-set network settings (General->Reset->Reset network settings)

- APN is set to isp.mb.com (Cellular->Cellural Data Options->Cellular data network)

- I tried getting out and putting back sim card, did't help.

- There is no specific user profile in General iphone settings.

- I see Public Mobile 32.0 as carrier in General->About menu.

What should I do to enable internet/data connection on my iphone ???

Appreciate your help!

Usually only recommended for iPhone 4 and earlier; anything running iOS 9 and up should pick up the required settings with a carrier update.

LOL, I didn't realize that. I have an unlocked 6S and when I first put the PM SIM in the phone it could not access data, so I installed the unlockit APN profile (I'd used it before on an iPhone 4, so I just assumed I needed to again). I just deleted the profile and I still have data access. I guess a little patience and reboot might have achieved the same result ;). Thank you for the info.

Thank you so much restoring the phone from iCloud really helped, although I had other issues associated with restoring, the data works well now.

Surprisingly however, the backup was long ago when I was with Virgin. So the restore set my APN to pda2.bell.ca.

And the data works!!!

How is this even possible???

[sergi]

I tried sp.mb.com. Didn't help.

I restored my old settings through iCloud. The backup was long ago when I was with Virgin.

So now my APN is pda2.bell.ca. Ant the data works!!!

It's a mistery to me.

@sergi, do you have a way to change it from isp.mb.com to sp.mb.com?

@sergi I think you should try to restore the iOS software via iTunes. If it still doesn't work, 

I recommend you send a private message to the moderator team and ask them to investigate that for you.  include your account# or phone#, as well as your account PIN (if know) to help speed up the identification process.

Oh. Do calls & texts function properly?

It all looks correct and matches settings on my SE. So last thing occuring to me would be 

to  ”force" change of your network settings.  

• Go to Settings

• Then go to Carrier, turn offf Automatic and select a network other than Public Mobile, Telus, or Koodo 

• When you exit the menu the phone should lose the network.

• Repeat the process and select Public Mobile as your mobile network.

If all that fails, I'm afraid you will need to try a factory reset. Do a full backup before you do, though.
