Hi, a couple of months ago I purchased the Optus X Sleek locked to Optus and I haven't activated anything, I have been using the blank sim with no number. Can I use this phone on Coles Mobile as they use the same network (Optus) or do I need to unlock my device?
Thanks for reaching out to us about this.
You can certainly use this device with a Coles SIM card as the phone is located to the network and not the provider.
Hope this helps.
Did the Coles prepaid sim work for you on the Optus locked phone? I want to do the same thing and would like to hear your experience
