The transfer was from a micro Tmobile sim to a Nano Tmobile sim (UK) - this was done in store.
Problem - only some apps recognise the WCDMA (3G) connection as a legitimate connection. Google Play Store, Spotify, Google Now, Google Now Voice and a few others will not connect to internet reporting back a "no connection" error or timing out.
Other streaming apps such as youtube, vimeo, vevo, facebook all work fine.
I have tried:
- WCDMA Only - no effect on problem.
- GSM Only - all apps work.
- WCDMA GSM Auto - no effect.on problem.
I have also bought a 3 UK pay as you go sim - this works perfectly with no errors.
The conclusion im coming to is I may have some issues with the APN settings for Tmobile UK (which in reality is EE-Everywhere) - however on the HTC One M8 the APN settings are locked, they can not be edited. I can add a new APN connection but it can not be selected.
Does anyone know how to unlock the APN options. I have tried Tweakker APN from Google Play but this has no effect.
Any guidance would be appreciated.
