How can I send a message to my relatives in Ukraine?

Let me tell you, the most convenient thing is that he sends you a text message first, and it is the simplest and most reliable way for you to choose to reply! If not, what Unicom mobile needs to add +38 before sending the number, followed by his mobile phone number. (For example, +380630932773, remember the digits. The international area code must be 12 digits. ) The international area code, just like China is +86, is definitely no problem! I forgot to mention, I am a Ukrainian student. If you don't understand, you can ask me!
