Hi, joined Smarty and finding it difficult to set up the apn for using my phone abroad, tried doing the suggested Xperia version but it won't accept, any ideas?

What handset have you got there @ANDREWL_1895440. 

Your topic title mentions Sony Xperia, but there is no Sony Xperia S20 5G handset.

Are you using a Samsung Galaxy? 
If you're using the Samsung Galaxy S20, the APN instructions are online at:
