Hi local sim card in germany will work freely in any foregin mobile phones only if it is unlocked one else if the phone is locked to some other network provider in other countries then it wont accept any other GSM sim until you unlock it ..You can easily unlock the phone through online providers like ProUnlocking.com here they are rendering network unlock code for all mobile models at reliable cost ..You first check that whether the code is available for your mobile model ,country and network provider .If yes then pay for it and unlock the phone then freely use it with any GSM sim ./...
