I have an iPhone 6S. My husband has an iPhone 5 (I think - just know it’s older than mine). We have AT&T for our service. My phone continually cuts out when I’m using it as a phone - only in my house. My husband’s phone never does this. Texting always comes and goes through and I can access the internet without any problems. It’s just phone calls that suddenly cut out. I can’t remember the last time I’ve been able to have a full phone conversation on my phone. Within a minute or 2, the call drops. I have to use our landline if I want to make a phone call to anyone whether I’m calling a cell phone or a landline. It also doesn’t matter if I make the call or if someone calls me. Any ideas on what could be going on?
Sorry if this is too basic, but iPhones will use Wifi for calls rather than cell service when Wifi is available. If the Wifi is intermittent, you might have problems with phone calls–these need to be be continuous, whereas texts aren’t always instant and we expect web pages to occasionally take some time to load.
The reverse could also be true–you might have great wifi in your home but crappy cell reception, only your phone doesn’t have wifi turned on.
Hope this is of some use.
Look at the settings for each phone and see where they differ. Also consider how you hold the phone. If you use his phone does it cut out?
To put a finer point on this, when you are at home, pull out your iPhone and look at the top left of the screen. It will have a certain number of dots (either filled in or unfilled), the word AT&T, and then a couple other icons right after that.
It could say 4G or LTE. If it says that and you have few bars of service, that is a problem.
I have poor cell reception at my house, but my iPhone connects to my in-home wifi and that provides the connection to make phone calls. If you are using wifi calling, instead of 4G or LTE you will see something like this: link. (Apologies for the poor resolution on the picture.)
If you need help turning on wifi calling, it is very easy to do. Just ask.
Thanks! I’ll try all of your suggestions tonight when I get home.
