IOS 16.6 cannot access data network, it must be a bug.

I have 4 iPhones below:

A: Iphone 11 pro with Koodo, IOS 16.6

B: iPhone 11 pro with Fido recently change to Koodo IOS 16.6

C: iPhone 14 Pro with Fido IOS 16.6

D: Iphone XR spare IOS 16.6

my son using iPhone B, recently change service provider from Fido to Koodo, it suffered phone cannot connect to data network, the SIM card changed twice, SIM card no problem with iPhone A C D , only iPhone B

we spent a lot of time with Koodo tec and apple tec, apple tec indicate we have bad battery with iPhone B. ask to repair the battery.

What I did after the call was:

ease all the content on iPhone D, then used Koodo sim card, it shows LTE and able to connect to internet (wifi disabled)
iTune full backup iPhone B, and restore to iPhone D, interesting things happen, iPhone D stop working and shows exactly same message, this iPhone D I changed the battery last year. must not be battery issue. it was working 2 hours ago before the restore, but stop working after restore.
sim card of iPhone A insert to iPhone B, same error
sim card of iPhone C insert to iPhone B, working fine.

please do let me know if you have similar issue. Please share you idea how to continue the trouble shooting as Apple tec kept saying this is hardware issue.

thanks.

Can’t access the web? Try rebooting i ph. I have I ph 12 with the latest update iOS 16.6. When problems come up I reboot. Use the volume up and down buttons- press in fast-first the volume up button then fast to the volume down button and let go fast-then fast over to power off button press and HOLD until apple logo comes on screen-then and only then let go and wait and do nothing until ph comes back on then swipe up and follow the instruction to punch in your pass code. This simple act has on many many occasions freed up a problem on i ph not working right. A quick bug fix THAT WORKS.

trust me , I reset network setting, re-insert sim card as much as possible, but still no luck.

I tried to get a Bell sim card still report same 3G issue that cannot access data network.

apple tec suggest me use new iphone instead of restore all the data....

Hi. I had this problem and usually you can resolve this problem by re-inserting the SIM card or re-starting the device
