This is potentially a workable model:
- PAYG dumb phone for emergency calls or inbound calls (Nokia and LG might make a come back in the dumb phone space)
- iPad mini LTE for everything else.
Let's look at some facts using my situation as an example:
- during the day, I am at work, if people need to reach me, they can call my work, send me a text (iMessage, whatsapp, etc.), e-mail (work PC or iPad mini LTE), or call my dumb phone if really urgent (rarely happens)
- after work, I am at home, I got WIFI, computers, my dumb phone, and my iPad LTE. This is usually when I will be conducting personal calls. Which people can text me to call them, reach me on skype, line, google talk, and many other VoIP application on my computer or iPad
- when I am out, dumb phone will serve occasions where I need to get a hold of someone quickly, or I can use a bluetooth headset/or earbuds, and make VoIP calls from the iPad mini LTE using say, MagicJack, GoogleTalk or Skype. Or people can reach me on my dumb phone.
Cost analysis:
Option 1:- iPhone 5 on contract with data plan and voice plan etc: at least $60/month or $720 per year, plus paying $199 for the first year and stuck with contract (assume don't cancel). So that's about $820 per year for 2 years (US) or 3 years (Canada)
Options 2:
- iPad mini LTE up front cost : $459
- Monthly Data Plan fee : say $35/month or $420/year
- dumb phone on PAYG : let's be generous, say $100 for 1 year.
Summary:
- The price for the device is about the same.
- You save at least $200/year
- Chances are you will probably have an iPad or a iPad mini even if you have an iPhone (so if you can skip the iPhone, you are saving the $199 up front cost, save yourself from contracts, and save at least $200/year - more if you are on a more expensive plan).
- I guess it makes sense if you are on a budget, but the savings are probably not too significant for people with a decent job to want to go through the hassle of implementing it.
