Do all of the 7's start after 05? Or do you also want to replace all 7's in the entire number?

If you only want to replace the first 7, you can do this:

UPDATE [dbo].[MyTable] SET Phone = '053'  + SUBSTRING(Phone,3,(LEN(Phone) - 3)) WHERE Phone LIKE '057%';

You can test it without risk by doing this:
SELECT  '053'  + SUBSTRING(Phone,3,(LEN(Phone) - 3)) AS Phone2, Phone FROM [dbo].[MyTable] WHERE Phone LIKE '057%';

(be sure to backup your table before trying anyone's code, that includes now )

If you need to replace all 7's then you just need this:
UPDATE [dbo].[MyTable] SET Phone = REPLACE(Phone,'7','3') WHERE Phone LIKE '05%';

UPDATE TableName
SET PhoneNumber = '053'+RIGHT(PhoneNumer,LEN(PhoneNumber)-3)
WHERE LEFT(PhoneNumber, 3) = '057'

UPDATE [dbo].[MyTable] SET Phone = '053'  + SUBSTRING(Phone,3,(LEN(Phone) - 3)) WHERE Phone LIKE '057%';
