Cannot make international call with Stateside International Talk service


    I switched to T-Mobile yesterday.

    My plan is $45 Simply Prepaid (4GB 4G LTE) + Stateside International Talk

    Today, I tried made a call to Vietnam, I heard a voice saying that "Your T-Mobile balance is too low to make a call..."

    I am confused since I have been charged 60USD yesterday, 45$ for Simply Prepaid and 15$ for Stateside International Talk.

    Please let me know the reason I could not make international call to Vietnam.


    Thank you.
