r/tmobile on Reddit: Guest payment for a past due balance?
September 11, 2024 -

hi y'all!

my sister is currently struggling financially and has a past-due balance on a t-mobile postpaid account. i'm getting a bonus coming up and would like to pay it for her.

i'm not an account holder or an authorized person on the account, so i'm interested in making a guest payment. obviously through the web site it won't show the amount due. will the store be able to help me? the only information i have is her (currently deactivated) phone number.

i understand that as i am not on the account or an authorized user they won't give me the financial specifics, but can i ask them to pay off the balance exactly, or do i need to go in with a specific number in mind (in which case i'll just do the payment online)?

thanks y'all!

r/tmobile on Reddit: T-Mobile will not allow me to use guest pay
June 7, 2024 -

At the end of last month, I ported out my lines and my account closed. Prior to closing, I asked if my account was protected by the uncarrier/price-lock guarantee where my last month’s bill would be covered. The rep informed me that no such protection existed (magenta max from a few years back) and I’ll need to pay my bill via guest bill pay after account close.

Now when I try the guest pay option using my account number, i get “We are unable to accept guest payments from this phone number provided at this time. To make a payment, please log in.” But I cannot log in, no longer have account access.

When I contacted T-Mobile, they’re stating I cannot make payments to a closed account without logging in. So what am I supposed to do?

r/tmobile on Reddit: How to pay a bill without account number?
April 19, 2025 -

I'd like to help my friend out and pay his phone bill but he's the type of dude that would never let me if he knew what I was up to, so there's no way I can ask him for the account number.

I tried the guest pay thing online but it didn't work and it asked for the account number.

Is there a way to pay a T-mobile bill or add a prepaid card to a T-mobile account with only the phone number? I've done it with Verizon before so I'd be kinda surprised if there's not a way to do it.
