Can you please be specific on what sim are you going to get and where will you use it?
If you want to get Globe sim and use it in South Korea via roaming, then you can make outgoing calls to any countries as long as it is supported and as long as it has prepaid load. The same with postpaid. For more details please call roaming hotline at 027301212 using any globe line.
yes it is possible. just dial *131* + country code + area code (or partner code) + mobile number + “#”. (i.e. *131*639171234567#). for incoming and outgoing call, Php80 per minute.
