Why doesn't iPhone 5 (US GSM) work with Germany's biggest carrier?
I bought an iPhone 5 16 GB during my travel to New York in December. The people at the Apple Retail Store at 5th Av assured me that the hardware will work with all major GSM carriers in Europe ... which now turned out not to be correct.
Because now - back in Germany - I can not use the phone because it just does not connect with my carriere's Network (Deutsche Telekom). SIM has been cross checked in plenty of other devices (EU Version of iPhone 5 / US iPad Mini / EU iPad Mini) and it works perfect in those devices. Only in the US GSM iPhone 5 none of the tested Telekom Nano SIMs worked. What makes it even more strange is that a German o2 (Telefonica) nano SIM works in the iPhone. O2 ist Number 3 in der German market - Telekom is #1.
Neither German Apple Support Team nor Telekom stuff were able to assist or come up with a solution - Has anybody here heard about this issue before? Am I really the first person on earth with this problem?
Thanks!
