no... as far as i know, you'll need her IC and thumbprint to request to change. so 2 options:
1) convince her to do it - (since number is under her name i assume she should pay the bill?)
2) prepare to change your number
Hi @danial1331 !
As far as I know, if your ex can't be there, could you at least get a Letter of Authorisation & a copy of their IC? If you have these documents, you should be able to change ownership.
Hopes this helps
