Correct me if Im wrong. I believe GoSurf299 is a 30-day subscription. If you already have a 30-day data promo on your current plan and wish to register to another, this is not possible due to "co-exsistence" policy of Globe.
For verification, you may also try to Contact Us for account validation and check what really seems to be the problem.
Have a wonderful day!
Yeah, I've just learned about it from customer service.So my only option now seems to be get 3-day plans, every three days, until my I can use my existing 30-day data again.
But thanks for the reply.
