Why Are Some Of My Calls And Texts Not Being Received Blu Studio Hd 6 0

Chosen Solution

Some people have been saying that they are calling and texting me but i have not received any of those particular calls or texts. My phone is the Unlocked GSM version and i have straight talk phone service.

I am having this problem, too, with my unlocked Vivo 8, T-mobile service.

Blu Android, boyfriend calls, rings once, goes to voicemail. What’s going on?
