Lori wants a simple smartphone for her mother that visits limited sites online and just make phone calls. Is there one that has loudspeakers, voice recognition, big buttons and a big screen? Leo suggests giving her an iPad for the websites, so she can see it. Then you can get a flip phone from Jitterbug that can handle the phone calls. A smartphone will be too small for her to use. You can also give her an LTE iPad that can make calls as well.
You may also be able to pair her hearing aids with the tablet so she can use the audio and hear better if the hearing aids are newer.
