Hi,

Does anyone know how can I unsubscribe i60 (prepaid) because I want to subscribe to UMI. I asked the promoter at Umobile kiosk, he said I can just subscribe to UMI and my i60 will be automatically unsubscribed, but that's not the case. When I try to subscribe to UMI, the system (*188#) said "You are unable to subscribe to this plan. Please proceed to buy the booster blablabla".

Help and thanks in advance!
