I have the TMOB S6E and a new NanoSim however i get a redirect when trying to use the internet. Something about upgrading.. blah blah blah. I have access to the network with the same sim on my TMOB G3 (D851) ... what could be the issue between the two devices.

Checked the APN: fast, epc, and the ancient wap.voicestream ironically all three worked on a donated sim..

Put the my personal nano sim back in my G3 and worked just like always, does anyone know what could be happening, why the block is only on the samsung device? what settings files anything i can move edit del to have my service continue through to the new device?

Thanks
