Hii AnshiSFDC

Trigger Is Working If Account BillingCountry And Contact MailingCountry Are Same then update Contact phone With Account Phone okay 
//First We Create Account With BillingCountry India
Account a=new Account();
a.Name='test';
a.BillingCountry='India';
a.Phone='2328938';
insert a;

//First We Create Contact With MailingCountry USA
Contact c=new Contact();
c.LastName='conname';
c.MailingCountry='USA';
c.AccountId=a.Id;
insert c;

//Then We Update Account BillingCountry here Cause If We Update Account Before Creating Contact The Trigger Will Work But It Will Not Be Able To Find  Related Contact Hence Contact Phone Will not Be Updated
a.BillingCountry = 'USA';
update a;
