[Samsung Galaxy S Blaze 4G] 2ndhannes:
Me too

Hi Erikmm,

first of all, a big Thank You for your work with the Blaze!

I'd like to give this issue a bump as I am also having troubles with mobile hotspot

I am using a sim-unlocked phone with a different provider, and when I try to activate the mobile hotspot, I get a message "mobile data is not available or invalid sim" - mobile data works flawlessly with the APN I configured for my provider.

From what I saw in the log, it appears that access data for T-Mobile is hardcoded somewhere in the ROM.

Here is the output of logcat | grep -i tether:

Any idea how to fix this? The normal settings menu for APN shows no reference to T-Mobile...

Thanks a lot

Hannes

Edit: pinternet.interkom.de is the correct APN; I've no idea where pcweb.tmobile.com is coming from...
