Using a Bali SIM card

[P_nicole]

Hello 

I’m going to Bali for a couple of weeks and I don’t want to pay £6 a day for my phone to work.

my phone isn’t unlocked so I can’t normally use any sim other than O2 

How can I unlock it to use a Bali sim for a couple of weeks while I’m away or will a sim from Bali already work in my phone?

If you bought your phone from O2 after April 2018 it is already unlocked.
