Address is: Russia, Kaliningrad Oblast, Sovetsk town, Shevchenko street, house 3A, apartment 58
7-59-97 seems like stationary phone number local to town. It needs country number + oblast code to make call from different country. Seems like 997-01161 is it, but I am not sure. Anyway cell phones inside Russia have different format.
If we search "how to call to Sovetsk" we can find this: Телефонный код Советска, код города Советск, Как позвонить в Советск, 40161
It states you need to dial next number for make call from another country:
00 7 40161 XXXXX where XXXXX is 5-digit number inside Sovetsk. Seems legit, you could try it.
