Since coming back to Australia and using the Australia SIM my 4G shows I have internet but to get the internet to work I need to turn mobile network off (4G disappears) then turn it back on again. Afterwards 4G works fine.
When I have the problem, 4G will show but there is no activity. If I try to check email for example the email app (default app) starts to refresh and then just stops like there is no new email.
When I was in England I had a notification that there was new software. I updated the software over the air. All seemed well.
The phone is completely stock and not rooted. I haven't tried anything to resolve really.. except these two things:
- Rebooting phone - problem comes back after a while say 24 hours
- setting the APN. If I choose another APN, for some reason the one I was originally on is re-selected somehow. I don't know how, may be the provider has some control over this? I use Telstra.
Any help appreciated.
