First, I can't english very well. Please understand.
I'm using optus prepaid optus usim.
If I will use same usim when i'm in korea, can i receive sms?
Or if can't, please tell me how to receive sms.
I don't need another. like send sms, calling etc..
Solved! Solved: Go to Solution.
You can use the SIM in South Korea.
You might want to purchase a OPTUS TRAVEL PACK for $10 a day.
Depends how long you are going?
You can also install an APP like WHATS APP if you just want to send messages to a few family and friends and not use SMS.
Thank you for your response.
You said I can receive sms without doing anything, right?
I just want to receive sms like internet banking certification.
My plan name is My Prepaid Ultimate but expired.
I just only use data add-on now.
Hey gorhkd0612 - thanks for getting in touch with us, sorry for the delay response. First of you'll need to check if your roaming is enabled for your service to work. You can ensure that it's switched on via your My Account here . You won't be billed for incoming SMS 🙂 For more details on activating roaming and further information click here.
