Hi all, please help me.
I have a iPhone 7 Plus and it is stuck on 3G. I went abroad for 2 weeks (where I didn’t use my phone) and have been back a week, but have yet to connect to 4G especially in areas where I usually would, the CBD for example.
There's usually a "reset network settings" option under cellular/network section of the settings in your phone. Try that 🙂
