Galaxy Fold Activation Failure Review
A frustrating experience attempting to activate a new Galaxy Fold, plagued by technical errors and poor customer service from the carrier.
I received my Galaxy Fold around 3:00 PM on September 30, 2019.
My excitement after receiving it was short-lived. I attempted to activate it, following the instructions that said I just needed to swap the SIM card.
However, no matter how many times I inserted the SIM, it wouldn’t work.
I kept getting an error message saying, ‘This is an unactivated terminal,’ and it told me to contact 02-1599-0011.
I called the customer center, and they told me they would get it activated even if it was late, so I waited... but in the end, it didn’t happen.
A day passed...
Today, October 1, 2019, it still isn’t working.
I have made eight calls to the customer center...
Still nothing.
The reason: Apparently, there is a ‘Data Sharing’ service on my current line that needs to be canceled first.
They only told me this around 5:00 PM...
When I requested an immediate cancellation, they said this had to be handled by the specific department at 114 (carrier support).
I contacted 114. They told me they would call me back and asked me to hang up.
I went into the T world app myself and canceled every single additional service I could find.
Still hearing nothing, I called 1525 again.
They told me the Data Sharing service was still not canceled.
With no further updates, I called 114 again to request the cancellation, only to be told that their business hours ended at 4:30 PM.
Are they kidding me?
Then 114 called me back just to repeat that their work ended at 4:30 PM...
They kept saying they were sorry, so I told them the consultants had nothing to be sorry for, but that I was just going to activate it with KT instead.
Ugh, so annoying...
Then they taunted me by saying a device bought from SKT cannot be activated on KT... Wow.
See if I ever buy anything from T World again.
Frequently Asked Questions
I inserted a USIM card into my Galaxy Fold, but it says it's an unactivated device. What is the cause?
This may be because the 'Data Sharing' supplementary service is subscribed to on your existing line. In the case of the original poster, activation via USIM change was not possible while this supplementary service was maintained, leading to continuous error messages.
Can I directly cancel the 'Data Sharing' supplementary service in the Tworld app?
No, it's difficult to cancel directly in the app. The poster accessed the Tworld app and canceled all other supplementary services that could be canceled, but 'Data Sharing' remained active, so they ultimately had to process it through the 114 customer service department.
What is the closing time for activation-related services at SKT's 114 customer center?
It's 4:30 PM. The poster contacted 114 multiple times to cancel the supplementary service and process activation, but was informed that related services had already closed at 4:30 PM, failing to complete the process on the same day.
Can a device purchased for SKT be immediately activated with KT?
No, it cannot be activated immediately. The poster, frustrated, told the customer service center they would activate with KT, but was informed by the consultant that a device purchased from SKT cannot be immediately activated with KT.
