If you dial a landline from another landline phone in the same area, then you do not have to use any prefixes, just dial the number. In our case: 7866658

If you are calling a number with a different area code – from another town or from a Hungarian Mobile phone-, then you have to dial the prefix 06 followed by the area code. For example to dial our office number outside Budapest you need to dial: 06 1 7866658.
Similarly, to call any mobile phones from a landline or a Hungarian mobile phone inside Hungary you need to dial 06 followed by the 9-digit mobile number, in our case: 06 30 3453132.
The most certain way to reach a mobile phone from anywhere to everywhere in the world is to dial + followed by the country code, the mobile area code and the number. To reach us from any mobile phone inside and outside Hungary.
