BULZONE and Office 1 Superstore- Bulgaria offer you the opportunity to stay connected
to the World in your eventual trip to Bulgaria. We are the only one who provide that kind of service.

As you know, the Mobile phone companies around the World use different frequencies for their services.
For example in the USA the frequency of the GSMs is 1900 Mhz, in EUROPE- 900/ 1800 Mhz, etc.
That means- if you don't have a 3-band cellular phone you won't be able to useit everywhere. 
So, if you live in North America, Australia or Asia and you go to Bulgaria you can't use
 your phone there. But now, using our service, you won't miss a call.
Even if you live in Europe, to avoid the roaming charges, you can 
use ourservices- we also offer SIM and prepaid scratch cards.
