I have a Jeenee sim card that uses the Optus network. Would that sim card work in an Optus locked smartphone? I'm wanting to buy the Oppo A73 phone that is locked to Optus, but am not sure whether my sim card can be used with that phone or not.
With most locked phones providing the provider is the same network the Sim card works.
Can you find someone with any phone locked to Optus and try the Sim in their phone. Of it works you should be ok with any phone make.
My preference would be to buy the OppoA73 online and unlocked for around $270. You can then use any providers Sim.
