Backdoor features in Sony Ericsson’s featurephones
I’m surprised nothing has been written about these features of some of Sony Ericsson’s newer phones.
Supposedly this should work on all their OSE-based phones (not Symbian or Windows Mobile) that were released during 2008 or later, according to a friend at Sony Ericsson. After this I might not have any friends there. Anyway…
If you enter ‘#speedy’ (as in the keys #773339) and press arrow down 4 times, you will activate HSDPA (as in high-speed downstream 3G), even if the phone is claimed to support only GPRS, EDGE or “normal” 3G. As all mobile radios today are software-programmable I guess this is to simplify production by using the same chips in all phones.
There’s also a code for getting no-cost data transfers (probably used by Sony Ericsson internally while testing in the field): Just enter ‘#outofcash’ (#688632274) and press arrow down 4 times.
I don’t know exactly what models this relates to, but it worked fine on my 760. The question is what operators think of this.
