How to turn call waiting on iphone?
When I click to turn call waiting on it comes up wih this and won't let me turn it on. Why won't it work? 
This " Call Waiting " can be enabled by your Cellular Service Provider only.
That feature (among others) is controlled by your carrier, not the phone itself.
- Will it show up as a missed call if i call someone by accident for half a ring? So I accidentally called my ex on his iphone, but I quickly realized my mistake and hung up after a half ring. Like you know how when you're calling someone it rings, I hung up after the first riiiing. My question is, will it show up on his phone as a missed call? I tested it out on 2 friends. One iphone 5 and iphone 4. They both told me they didn't get a call. Am I in the clear?
- Is there a way to forward calls to another number that are call waiting? Iphone 7? I know how to forward calls and set up call waiting but is there a way for forward the calls that are on call waiting to another site when I'm actively on the phone with someone
- IPhone 6s Plus, how do you mute a call while on call? (not how to mute ringer)? I have a new iPhone 6s Plus and need to listen in on conference calls without other people on the call hearing me type in the background or the kids, so how do I Mute the sounds on my end so I can listen in without disturbing the others on the call? My current phone keypad on the iPhone 6s Plus only shows 1-9,0 *, and # buttons.
- Does a call go through right away when you call someone? I got this iPhone 5 and I was on Facebook scrolling through stuff and I guess i hit someone's phone number and my phone automaticity started calling the number. I hit end as soon as I could but did that person get that call? I accidentally called someone before and I didn't think it went through cause I hit end right away but they kept calling back. I just don't want this person to have my number.
