Hi i wanted to buy a booster with onebip on my prepaid card but when i wanted to register it says "sorry this service is unvailable for prepaid customer users".do i have a problem with my phone or is it just the tb thingy.and it has a $60 sgd balance

Maybe you can`t register OneBip with a prepaid card...:-?

i can.it says so clearly on the registration page.and the faqs page
