My brother, mom, sister, & so on can call me, but if I try to call them, I get a busy signal. I already rest my iPhone X and my bill is not over due. What’s going on?
This can be frustrating, I understand what you're going through. Are you by chance using WIFI Calling, or Calling Plus when you are making these calls?
My mom has a LG V30. Starting last weekend she noticed when she calls some landlines she just gets a busy signal. She is not using wifi calling or calling plus or anything nifty. She does have a blocked number – but we know that only one of the landlines she’s calling does actually block unknown numbers (previously dialing *82 and then the number worked for her with this landline). She’s been to a store to try and get assistance—they did a reset, changed sims, etc. But still no resolution. Any ideas on what could be going on here?
