Can you use an old iPhone 4s for just music & apps, not a phone?

My dad got an IPhone 5 & still has his old IPhone 4s. He said he will give me it as I need an IPod for music. I don't want it as a phone because I hate contracts/plans & won't do them-only pay as you go. I've searched & ppl said I need a IPhone sim card. Would I need to go to a place like Rogers to get one or will I have to have it as a phone still? Never had any phones that have been able to have Internet before… Btw I'm old fashioned & prefer flip phones lol

IPhones don't have simcards. All you really need is an iTunes account, and I'm pretty sure you can download iTunes for free. Just make sure to go into settings and turn it to airplane mode when not downloading things or trying to do anything online. There's no reason for your phone to be constantly spending battery searching for a signal if you're not even using it as a phone. You can actually even still use apps of all kinds on it through that iTunes account, without having any kind of service plan whatsoever. You can also still use all internet features over Wi-Fi, and set up your phone to only use data on Wi-Fi. No simcard or service plan needed.

So I'm assuming your dad wants to still be able to use the phone function on his new phone and you don't. Take the sim out of the old one and put it into your dad's new phone. Voila, you don't have a phone function, but can still use music, app etc. You won't however have 3G or roaming as I think to get a package with 3G you have to also buy a phone plan. You can use Wi-fi however.

Yes you could use it for that, but in the setup process, since it is a phone still, you'd need to activate it.
