Well it might have worked…

Having written about my iPhone 6S Plus connecting to 4G problems.

So the issue I have is I have been at home on the Wi-Fi, I leave the house and then wherever I am I check the phone as find that it says.

Could not activate mobile data network Turn on mobile data or use Wi-Fi to access data.

The only solution was to go into airplane mode and then turn that off. At which point all works fine. Even if you turn off mobile data and turn it back on again, that doesn’t work. It’s airplane mode or nothing!

I said that I was going to upgrade my iPhone to the latest iOS, 13.5.1 which I did and went fine.

Since then has it worked?

Well I have been out a couple of times and I think it’s being fine, but watch this space!

My 4G still keeps getting lost….

Back in January I blogged about issues I was having with my iPhone 6S Plus and the Three network.

The problem is still happening, it’s just that I notice it less as the lock down restrictions meant I was driving a lot less (so didn’t use the phone for music and podcasts, which I use to do for long journeys). Even when walking and cycling as part of our government sanctioned exercise I wasn’t using my phone.

So the issue I have is I have been at home on the Wi-Fi, I leave the house and then wherever I am I check the phone as find that it says.

This is even with 4G being in the top of the phone. Clicking OK results in no change. You are still not connected to the internet. As you can see in this screenshot the phone does show 4G at the top.

What’s interesting, was that I thought it might be a handset issue, but family (also with Three) are having similar issues with their iPhone 6S and a newer iPhone XS.

At the moment, the solution is to go to airplane mode and then turn that off. At which point all works fine. Even if you turn off mobile data and turn it back on again, that doesn’t work. It’s airplane mode or nothing!

I am going to update the iOS on my phone, which I haven’t wanted to do, as newer iOS upgrades often result in different problems on older phones. I think it might be an phone operating system issue rather than the network. Having said that, Three are working on the network this week, so I will probably wait until next week, just in case. If I still have the issue, it’s upgrade time!

Where’s my 4G gone?




Over the last few weeks I have been having an issue with my iPhone 6S Plus and the Three network. Over the last four years I have had very few if any issues with my Three data connection, so it’s weird I am having an issue now.

It’s not isolated to a single tower either, as it happens locally and further afield.

I don’t have a real solution and it appears from searching online others are having similar issues as well.
