The guy who will resolve my problem is a genius ! I have an iphone 6 (IOS10.3) that I bought in France.
I have a t-mobile sim card simple choice I add Canada roaming. Usually I don't have any problem as soon as I arrived in Canada I just need to insert my sim card on my iphone.
Since this month, I can make and received calls, I have coverage , I have the "3G" icon BUT NO DATA.
When I try to navigate on google for ex I have the message : "You are not subscribed to a cellular data service"
I talked to t-mobile 1000000 times. they confirm that my plan include data in Canada.
I tried my sim card on android phone i change the APN and I HAVE INTERNET.
So I tried to reset my settings, I tried all the manipulations with a reprentative nothing worked! The guy told me my sim card is not working!!!!!!!!!!!! but its working on another phone ??!
AND THE BIG PROBLEM, i can't change manually the APN (which resolved for sure my problem). When i click on Settings/Cellular I DONT HAVE "CELLULAR NETWORK" !!!
I have only Cellular DATA / LTE / DATA ROAMING that's it !
When I insert my french sim card I HAVE THE CELLULAR NETWORK AND I CAN CHANGE THE APN ! but as soon as i insert my t-mobile sim card I DONT HAVE THE CELLULAR NETWORK APN anymore....
If someone can help me please ! I am desperate
I thought I can assist a bit. Not that I have the device in front of me, but from what I understand is you put your Canadian SIM into your UNLOCKED T-Mobile device and you are currently on the Canadian network. First off the moment you put the Canadian SIM into your iPhone it automatically detected that your Canadian SIM on the Canadian towers and downloaded the (Settings-->General-->About.....Carrier) Carrier settings for Canada. The T-Mobile Carrier (Settings-->General-->About.....Carrier) should read T-Mobile 27.3 or something like that depending on your iPhone model. I do not know if T-Mobile is authorized to send its Carrier data settings to your phone while on another network. But connect to iTunes or find an available WiFi so the correct carrier settings can be transferred to your iPhone.
Update your carrier settings on your iPhone or iPad - Apple Support
Hope this has Helped.
