Because I can not stand the mobile phone radiation on the head and ears I rely mainly on phone with a landline telephone. This was much more costly in Austria in comparison to the mobile phone tariffs + free minutes so far. The Voicebox Vodafone is finally an alternative. It is a top-quality product at a very good price. The connectors are also with us in Austria, the device is mounted quickly and easily, the reception from the external antenna is super! In my network operator I have requested a second SIM card (cost 6 euros per month in addition) and connected my landline phone with this SIM on the voicebox. Now when a call is ringing my number cell phone and landline phone at the same time and I can decide where I take off. Now I call on both telephones which saves me a lot of money a month with my free minutes. I am thrilled and can only highly recommend this product!
