I've just came from abroad where used a different sim card. Upon my return, I can't access data on my phone.
When I try to open a tab in Safari it says: "Could not activate cellular data network. You're not subscribed to cellular data service"
I tried the following tips I found online: Soft reset, Cellular Data on/off, Reset Network settings, Reset General Settings, Airplane on/off, Delete Safari cookies/website data, Delete profiles under General (there were no profiles there), Updating Software. Nothing worked and the problem re-occurs.
I also went to the Fido store where I changed my sim card, but they weren't able to help with this issue.
Everything works if I insert my sim card into a different phone.
Would appreciate any help here.
Thanks for letting us know.
Can you try a Cellular Data Reset?
You can find it in Settings - Cellular - Cellular Data Options - Cellular Data Network - Reset Settings.
Keep us posted if this changes anything.
Hello there @alexv27
The last thing you're going to have to try is a full restore of your device through iTunes.
You will want to do an iCloud backup beforehand to save your stuff, because if you are experiencing a software issue, an iTunes backup might recopy the same issue so better to avoid that from the start.
If after a complete restore, you are still experiencing this issue, you'd have to start looking into a replacement option. Good luck!
My iPhone X is unlocked
I bought the SIM card from a Fido store here in Quebec. For the activation I went online to do that but I did not find ay activate sim option. Can you please tell me how to do that?
