MintMobile resells T-Mobile. It was formerly called MintSIM. It's inexpensive but has this persistent problem of not receiving calls. Tech support in Dominican Republic is basically: turn the phone off, then back on.
When? If the caller did not leave a voice message there's no way to know that you missed a call.
