CELL phone needs a refill

hace 3 años

Hello, everyone!

In Russian (Ukrainian) we alsways say, "I need to refill my account." That's it. No more words. Just this tiny phrase that we say when our MOBILE/CELL phone is out of credit. Now, here comes the question.
What is the phrase that you personally use to express the necessity to refill you (MOBILE/CELL phone) account? I guess you won't say, "I need to refill my account."

Thank you very much!
