Telephone country codes never begin with zero.
Country code +93, dialed as 00 93 from many places, is Afghanistan. A number beginning with +93 7 is most likely a mobile phone.
Country code +37, dialed as 009 37 from many places, is an incomplete country code in Europe. You need one more digit.
To avoid confusion, it is best to write an international telephone number in correct international format, beginning with the plus symbol and the correct telephone country code (e.g., +93 or +370), omitting any dialing prefix.
(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
