I purchased an iPhone 6 Plus late last year to replace my iPhone 5 and it's a great piece of kit. Excellent battery life, screen and the size is great for what I use it for on a daily basis. With my
device family now consisting of an iPhone 6 Plus, iPad (3rd generation), iPod touch and MacBook Pro, I'm enjoying the synchronicity between everything. As they've always said, everything just works!
I was wondering, however, if I'd be able to bring my old iPhone 5 back in to function as another device to listen to music/play games when I'm on the road for a long period of time with no access to charging. Obviously I know I can switch it back on and get functionality from email/app store as was. My main wonder was whether I'd be able to get Text messages forwarded from my iPhone 6 Plus and allow the iPhone 5 to send on behalf of it? Would I need to put a SIM card in the iPhone 5 or would it function without? Making and accepting calls isn't essential, but if it works alongside the message functions, that would be a bonus.
I'm sure someone else has must have tried this out in the past - I've had a quick search through the forums, but couldn't find a precise thread about it.
Look forward to your replies!
