The combination of upgrading to iOS 10 and installing the latest carrier updates appears to be causing issues for some T-Mobile and Telstra customers in the United States and Australia respectively, crowdsourced information suggests.

tmobile
A number of T-Mobile and MetroPCS customers claim that once their iPhone loses service temporarily, the device is unable to reestablish a cellular connection unless it is fully restarted or network settings are reset. The issue appears to have started after the latest 25.1 carrier update on iPhones running iOS 10.

MacRumors reader GCHASE1995:

Anyone on T-Mobile that has done the carrier update to 25.1, have you been getting no service? I can't get service at all. I can get it, if I reset network settings. Then if I lose service I can't get it back.

Reddit user Hitokill:

I am in the same boat as many others. If I can stay connected to the LTE network the 25.1 update is fine. However, I work in a building with certain areas that have no coverage. Once I walk in those areas and lose signal, then walk to an area where I normally have full bars I can't get it back on no matter what I do (hard reset, Airplane Mode, etc...) The only fix I found was going into settings and Reset Network Settings. Totally sucks but that is basically what I have to do. T-Mobile rep said he did something on his end too, but didn't fix the issue when it came back.

Meanwhile, several Telstra customers in Australia report that Visual Voicemail no longer works after updating to iOS 10 and installing the latest carrier update. "I have no indication that a voicemail has been left and nothing shows up in the voicemail section," wrote one user. "Voicemails are definitely being left though."

It is unclear if Apple is aware of these issues, but they will likely be resolved in a future software or carrier update.

Now who's to blame here?

Apple is probably already "investigating". As usual. Something they prefer over testing prior to rollout.

And they will claim that only a tiny insignificant amount of users were affected. As usual.
Carrier update not Apple update. It's T-mobile's burden to fix.

This is happening to me. It won't automatically reconnect to the network after losing signal. I also updated through iTunes. I'm hoping T-Mobile rectifies this soon. I don't want to have to revert to 9.3.5.
Reverting to 9.3.5 will not resolve it. Its a carrier update not iOS.

A Telstra employee replied ('http://whrl.pl/ReIo1X') in that Whirlpool thread, confirming they are aware of it, and it's not limited to iOS 10.

Just a update – we've narrowed the issue down and it is not specific to iOS 10, we've found it on users with iOS 9 as well. Still working to address it.

T-Mobile is to blame.

Of all the things on an iPhone, the only part that Apple doesn't have control of is the carrier. If T-Mobile pushes out bad settings and there's something wrong with them, that's no more Apple's fault than an app in the app store being buggy. Less than even most there, in fact, since the bug only appears when interacting with an external piece of hardware (the cell tower), at that.

That said, it certainly isn't everyone--I'm on T-Mobile and both of the phones in my house seem fine.
