Applied at Sydney.Took my own photo required that was taken in last 6 months on phone.Kept coming up saying may not be accepted because more than 1 object in photo.After taking several different pics just submitted it and was accepted.
You can have multiple esims but only one can be active at any time.not all modern phones have esims capability.Have Woolies in Oz Esim and True Thai Esim on my phone.Just a matter of switching back and forth in connections.
I had a tourist visa and returned to Oz on 28 November then applied for another one and returned to Thailand on 25 December with new tourist visa.Both from Sydney.
